The upper part of the smartphone sensor does not work. The sensor on the phone does not work - what to do? Repair of touch phones. Features of the operation of electronic devices

Modern gadgets have become an integral part of our lives. The telephone is the most common gadget. Almost every person has it. Unfortunately, even the most reliable phones can break due to shock, water or software failures. The most common problem that many mobile device users face is that the sensor does not respond to touch. If the device is still under warranty, then you should immediately contact the service center. Otherwise, there is no need to rush, because there are cases when the problem can be easily and quickly fixed. The sensor does not respond to touch, what should I do in this case? Let's look at all aspects of this problem.

Phone screen repair

Before solving the problem, you need to make sure what is causing your display to break down. This could be mechanical damage, liquid getting inside the device, or software glitch. If you are sure that you did not drop the phone or spill liquid on it, then we can assume that this is a software glitch.

Cleaning your mobile phone screen

First, you can simply clean the display of your device. You will not harm the phone in any way, but improve the connection and perhaps the problem will be solved. This method may help if the sensor does not respond to touch. What to do?

Take a suitable cloth and liquid to clean the screen. It is better to use lint-free or any other natural fabric. To clean the display, we will need a glass or monitor cleaner.

If this method does not help, then you should move on to the next steps. Of course, they may not help either. Only a professional can determine the true cause of the breakdown, but even he cannot solve every problem.

Software glitch that caused the display to break

If the display mobile device sometimes reacts to your touch, then you can try Hard Reset systems, this full reset settings. But it’s worth remembering that this can only help if the sensor glitches from time to time. After resetting the settings, install applications that can clean system registry. This will eliminate errors caused by RAM. Recommended applications are WinFixer and Cleaner4. Unfortunately, the second utility is paid, but has good functionality. The first program is suitable for you if you are not sure of the reason why the display does not respond well to touch, and you are not going to spend money.

All actions should be performed without a memory card. It may contain viruses that cause system malfunctions. After resetting the settings and cleaning the registry, you need to put the SD card in place and scan the device with an antivirus. Select full check devices and wait. But even after these actions, the sensor does not respond to touch. What to do? In this case, it is necessary to proceed to replacing the sensor, since the reason is not caused by a software failure.

Mobile phone display replacement

The sensor does not respond to touch - what should I do? If previous methods did not help, then you need to replace the damaged display. Most often, this needs to be done when the device has been dropped, cracks have appeared, or moisture has entered. In the latter case, you may not even notice how liquid got into the phone, as this can happen due to temperature changes. Thus, condensation that accumulates in a mobile device will interfere with the normal operation of the phone. At first, black spots may appear when working with the gadget, and later the sensor itself will stop responding to touches. In this case, you will need to change the screen.

Phone screen repair - not too much difficult process, the main thing is attentiveness and accuracy. Any person can do this. The sensor does not respond to touch - what should I do? First you need to disassemble your device, but you should remember the sequence of actions so that there are no problems with assembly in the future. All plugs and latches are removed using a thin object. You will need to carefully remove all elements from the latches with this object.

After disassembling your smartphone, you need to remove the display. It is necessary to check how the display is attached to the matrix. This can be done in two ways: monolithic or separate. This is very important, since when ordering a new screen, this aspect will need to be specified.

The sensor can also be connected to printed circuit board different ways. Exists contact method, in this case the sensor is simply disconnected and is wired. In the latter case, you should be very careful.

If you need to detach the matrix from the sensor, you must follow these recommendations:

• First, heat the surface to 60 degrees. This can be done using a regular hair dryer. It should be heated evenly so that the glass does not crack and the glue heats up.
• Next, you need to find a flat and thin object to easily disconnect the sensor from the matrix. To do this, simply pry the edges and carefully lift them up.

All that remains is to attach the new sensor. How to do it? The kit should include the sensor itself and glue. First we apply special glue, and then carefully attach the sensor.

Cost of a new display

How much does it cost? Of course different models For smartphones, the cost of the screen will vary. On average, to change the display on phones with a diagonal of 4.5 or 5 inches, you will need to pay about 700 rubles.

If you don’t want to disassemble the phone yourself, you can contact a specialist. The master will ask about 2000 rubles. Although this procedure is not very complicated and you can change the screen yourself. You just need to approach this carefully and carefully.

Touch buttons don't work

Lower touch buttons directly relate to the screen and in the event of their failure, it is necessary to perform all the actions that we have already considered. If the touch buttons do not work, you should first do a full reset. Next, clean the system registry and scan your device for viruses. Unfortunately, if the steps taken do not help, you will need to change the screen.

Touchscreen not working? What to do?

What to do if you just replaced the screen, but it completely stopped working and responded to touch?

This is one of the most unpleasant problems, because the touchscreen is the main and only option for functioning and working with the device.

In this article we will look at the causes of this problem, ways to solve and prevent it.

If after replacement the touchscreen stops working, then you need to understand what could have caused this problem.

Causes of malfunctions

• Accumulation of debris inside the device;
• Problems with connectors;
• Crooked display;
• The screen is damaged during replacement;
• Damage or break in the cable.

Ways to solve the problem

The problem is serious, but like any other, it has a solution. These issues may occur if your device has an LCD screen.

• Try rebooting your gadget. Most often this is the method that works.

• If rebooting does not solve the problem, perform a hard reset of the device. In this case, your personal data will not be lost. How to do it? Each device has its own special combinations that are different from others. Therefore, you need to look at the instructions for your gadget or search for it on the Internet.

• If the touchscreen doesn’t work the first time, this is not a reason to panic. After all, the whole point may be incorrect installation sensor if the technician made an error in touching the sensor with the screen.

Here the device needs to be opened to check this. First of all, remove the protective cover of the screen, because the reason may lie there.

Advice:

do not rush to remove the cover and disassemble the device if you have not yet fully verified the functionality of the screen without internal intervention.

Checking the loop

If it is not connected tightly to the display, then it needs to be reconnected and checked for functionality.

It is also necessary to check the connection with the contacts, whether they are inserted completely.

If they suddenly become oxidized, you need to carefully clean them with an eraser.

But if there is any visual damage there, it needs to be replaced.

If the contacts are not connected properly, there may be incorrect clicks or the screen may not work at all. You should disassemble the device, insert the cable well and put it back together.

If the contacts are pressed through by other contacts, for example, from a connector, then the cable must be inserted all the way and pulled out one tenth of a millimeter so that the cable rests on the new contact points of the pad.

It so happens that the controller soldered on the cable turns out to be incompatible with your version. This often happens with gadgets from China.

Then you need to unsolder the controller from your old display and solder it into the new screen.

If you cannot do this yourself, due to lack of experience, take it to the masters who understand this.

• There is a protective film on the display. If it is of poor quality, it will affect the performance of the screen, reducing sensitivity to touch. Therefore, remove it and wipe the screen with a special cloth.
• Requires calibration. Try turning on your device without using the sensor so that the controller can rewrite the data about the new screen. During the download, its firmware will be updated and after the update the system will start.

This procedure is called screen calibration. It is used for strong and weak screen sensitivity, as well as for complete absence sensitivity.

Basically, calibration is performed using special applications.

In most cases, this relates to ignorance of certain features of use, as well as careful attitude to technology. For example, after replacing the touchscreen, part of the screen does not work, and you were confident in solving the problem using this method. Obviously, it will not be possible to solve it if the attitude towards technology remains the same. Therefore we will consider everything possible reasons, why part of the touch screen does not work.

Part of the screen on the phone does not work

So, experts almost always advise using the method of elimination. The fact is that part of the screen on an iPhone sometimes does not work due to the simplest little things, which can be easily eliminated, and sometimes you have to completely change parts of the equipment.

Part of the touch screen on your phone is probably not working due to one of the following reasons:

1. Sometimes part of the touch screen does not work due to simple memory overload. In our pursuit of greater opportunities and the desire to store as much information as possible, we do not notice how we simply overload our equipment. As a result, there are no more resources left for the touchscreen. And sometimes the equipment system fails, then you have to resort to the so-called deep reboot.
2. Part of the screen on a smartphone does not work after careless handling. When was the last time you cleaned your screen? When traces of dirt accumulate on it, greasy spots, contact becomes worse and sensitivity decreases.
3. The technique cannot tolerate temperature changes. This is one of the reasons why it is not recommended to carry your phone in your jacket pocket in winter. By the way, such changes can lead to condensation, which also leads to problems. The contacts begin to oxidize and the sensor starts acting up. In such a situation, it is enough to wipe the contacts with a cotton swab dipped in alcohol.
4. In a cramped bus or just in sudden movement, you won’t even notice how you damage your phone. Part of the screen on the phone does not work after the smallest cracks appear.
5. It is likely that part of the touchscreen on your phone is not working after a slight shift or partial peeling of the touchscreen itself. Here you can use the heating method with a hairdryer. The fact is that the sensor is fixed with a small layer of glue, which can be heated and set everything in place.

Why is part of the touch screen on my phone not working?

Components electronic devices may break if used carelessly. If part of the touch screen on your phone does not work, this may be caused by both temperature conditions of use and mechanical damage.

Competent diagnostics will help you repair a smartphone or tablet screen that does not respond to touch. Sometimes it helps easy cleaning, combined with disassembling the housing. However, if after all the user’s actions the device does not turn on, it will have to be taken to the service, and this may lead to additional costs.

Causes of failure

There are the following reasons why part of the screen does not work:

1. Oxidation of contacts due to condensation. Moisture trapped inside the device can lead to complete or partial loss of functionality. Oxidized contacts stop responding to processor commands and transmitting them to the screen. To eliminate the consequences of liquid ingress, it is necessary to disassemble the device and clean the internal components. To do this, you can use alcohol applied to a cotton swab or swab. After this procedure, the phone should turn on in normal mode.
2. Cracks on the surface of the screen. Due to microdamage to the sensor, it stops responding to pressure. Such damage occurs due to falls or impacts on the screen. You can identify cracks in the display by carefully examining its surface. If part of the touchscreen is covered with cracks, then it is possible to restore functionality by replacing the touchscreen of the device.
3. Disabling touchscreen contacts as a result of displacement. This usually results in the bottom or top half of the screen not working. To diagnose contact displacement, you need to disassemble the device and see if visual order symmetry of components. If you see misalignment of the contacts, you can try to correct them using tweezers. In addition, some elements are fixed with glue, which can high temperatures melt and dislodge the contact. In order for the upper part to return to its place, you need to heat the mount with a hairdryer and return the component to its original position.

Features of the operation of electronic devices

In addition to the listed breakdowns, electronic devices may begin to malfunction due to the features interior architecture. Limiting the size of components affects their power reduction if the tablet screen does not respond to touch - this may be due to the device being overloaded big amount resource-intensive applications. For prevention, you need to start the task manager. Find out what is loading the device’s central processor and disable unnecessary applications.

Electronic devices have increased sensitivity of screen sensors. A situation where the screen of a tablet or phone does not work may be due to simple contamination. The adhesion of grease and dust to the surface causes the tablet to not respond to touch.

Free legal advice:

If the screen on the tablet does not work, the most the best solution will take it to a service center for diagnostics. Most models have a very long warranty, which will allow you to replace the device with another device without defects or get your money back at no additional cost. If the case is not under warranty, perhaps you should just buy new gadget and subsequently treat it more carefully.

The touchscreen on a mobile phone does not work: we fix it ourselves

Free legal advice:

Good afternoon, dear reader!

Today I will tell you a story from my life. This is not just a story, this is practical advice. It’s not for nothing that this article is located in the “Everyday Affairs” section.

I have several phones. Yesterday on one of them the touchskin (or touch screen) is a touch screen that completely replaces the physical keyboard.

As usual, he “died” partially, but this was quite enough to completely paralyze all work.

light spot

The sensitivity on the narrow strip on the right has disappeared. The phone was turned off at night, and in the morning I tried to turn it on. This procedure is accompanied by entering a password. And I need this narrow stripe on the right, since I will use the number located there.

As a result, I couldn’t even turn on the phone. As usual, calls began to service centers and answers: “Leave your phone number - we will call you back once we check whether we have such a touchscreen or not.” As a rule, everyone promised to call “today or tomorrow.” What should I do right now?

Free legal advice:

In general, there was only one bright spot in this whole story - the Internet. Why light? Because you will always find answers to 99% of your questions on the Internet! I found the answer too.

Which? I'll tell you now.

Where can I get it?

If the touchscreen on your phone is “covered with a copper basin,” you will need a piezoelectric element to “resurrect” it. Where can I get it? Of course, in a piezo lighter. But I don’t have a piezo lighter at home: with a handle, on a wire or a battery - there’s no such thing.

But there is a piezoelectric element. It is installed on the hob of my gas stove. Turning the burner knob, I open the gas. At the same time, I push the handle down and turn on the piezoelectric element. This is how I light the burner.

In general, I need a piezoelectric element, but I don’t need gas. I turned off the gas valve. Turned off my phone. I brought it with the screen to the piezoelectric element: the place where my touchscreen “died”. I turned on the piezoelectric element and moved the screen for a few seconds so that the spark covered the “dead” area of ​​the touchscreen.

Free legal advice:

After that, I turned on the phone, and - lo and behold! – the touchskin is working! He really recovered! He became fully operational!

The effect lasts...

Various sources on the Internet report that the effect of such resuscitation lasts from several days to one month. Today is my second day since the touchscreen “came to its senses” - everything works perfectly.

Of course, it is necessary to replace the touchscreen, but resuscitation from a piezoelectric element as an immediate method is simply great!

If my solution helps you, I will be only glad! Have you ever experienced a sudden “death” of your touchscreen at the most inopportune time? How did you solve this problem?

Comments

Very interesting. I would never have thought of using a piezoelectric element to resurrect a phone. In my experience, this has never happened before; the phone did not fail on its own. There were problems with the batteries due to the exhaustion of their resource. I took note of your case. Thank you.

Timur, I would never have guessed either. While I was looking for a solution to the problem. I read about another method: swipe the phone screen across the TV screen. I have regular TV, not LCD. This is what you need to use. I tried it, but it didn't have any result. And with the piezoelectric element from the hob, everything worked out, which plunged me into indescribable delight. And I immediately shared this method))

Real miracles of technology) Thank God, I don’t have any problems with my phone, but now I know exactly how to urgently resuscitate it)) If only there was some other method of enlarging random access memory laptop using a frying pan or repairing an air conditioner using raw smoked sausage)))) Share such extraordinary solutions to everyday problems more often) thank you)

Hello Mihas! That’s exactly what I thought when I was looking for a way to resuscitate the touchscreen. And when I read about using a piezoelectric element (and before that, about a TV screen) as a tool to return the touchscreen to normal operation, I grinned for about five minutes. Exactly until the touchscreen started working)

In general, in the world, as I understand it, there are many different ideas and methods that initially cause a smile and even laughter, and then surprise and even amazement. That’s exactly the amazement I experienced when I revived the touchscreen using a “lighter” located on the hob surface of my gas stove))

Free legal advice:

As I understand it, we're talking about about electric ignition on a gas stove? The strip on my touchscreen phone hasn’t worked for a year now, I also scoured the internet and couldn’t find anything like it. Do you need to expose your phone to a spark? I'll go try it)) There's nothing left to lose on the phone))

Anastasia, I used exactly the ignition, which is built into the hob of my gas stove)

The narrow strip on the right didn’t work for me either: probably 5-6 centimeters wide. I turned off the phone, turned on the piezoelectric element and moved the “dead” part of the screen over the spark so that it touched this area. Literally a few seconds. Then he turned on the phone. That's all. He earned it))

In my situation, a complete replacement of the touchscreen was required. The phone fell on the asphalt unsuccessfully and the screen broke. As a result, it took me a week to repair it; I spent a long time looking for spare parts and some special tape. The repair cost 3 thousand rubles.

Good evening, Vladimir!

Free legal advice:

The touchscreen in my situation also needs to be changed. I have already reanimated it using the method that I gave in the article))

The point is simply that this option is momentary. Here's how to call or write down a contact from your address book right now. For such a case, using a piezoelectric element on the hob is a very good solution))

Sergey, good evening! Indeed, a most interesting way. Someone thought of this! So far, the only touch phone in our family has broken down - that of our eldest daughter. Once I revived it by resetting it to factory settings, getting into a menu with a bunch of lines consisting of hieroglyphs - I chose a line at random, I was lucky. Now that he has died for the second time, I will try to replace his firmware - also according to instructions from the Internet)

As they say, one head is good, but two are better. And the Internet contains ideas and practical ways to solve various everyday problems from a huge number of people. The scale of the information presented is enormous - the whole world!

It is not surprising that you can find answers to almost all questions on the Internet, since, probably, any life situation that happens to a person has already happened to other people. And some, the smartest or luckiest, have certainly already found a way to emerge victorious. And you just need to find a way to solve your problem that someone else has already thought of)

Free legal advice:

I’ll add: I thought of it and didn’t keep silent about it, I shared the method with others. Many specialized forums and communities contain so much useful information that you can only be surprised and admired) Well, use it as needed.

Konstantin, I agree with you. Today there is actually information great amount. In this situation the main task- be able to find the right one.

It seems to me that the Internet today has answers to almost all questions. If 20 years ago you had to dive into some serious problem on your own and spend a huge amount of nerves and time on solving it, today to solve the vast majority of questions it is enough to be able to search and find answers. And I personally have no doubt that they exist.

If the question is specific - you are right, Konstantin - often it is enough to find a popular and authoritative thematic forum, register there and ask for help. They will definitely help!

Sergey, thanks for the advice. As soon as touch phones appeared, I immediately became concerned about this kind of malfunction. I even for a long time I didn't buy a smartphone. But time passed. I didn’t want to go with a model from the age of dinosaurs, so I bought it. No problems so far. But as they say, it’s better to arm yourself with knowledge for the future. It is especially useful for us women to know “what to do” in order to problematic situation don't be hysterical.

Good day to you, Arina!

You're right. Useful little things never hurt. If everything works for you now, that’s great! And let it continue like this! May your touchscreen never die. And let you change your phone for only one reason - you just want something new!

But if, God forbid, something happens, if something somewhere stops responding to touch, you will already be fully armed. And remember how to revive “dead” zones. And if you don’t remember, come to my blog and read it again))

Not only the article on restoring the functionality of the touchscreen, but also any other articles - go to my website and blog, read, leave comments! Always welcome!

Sergey, hello! I haven't been to your site for a long time. And here you can find and read a lot of interesting things. I saw this in this article original solution“resurrection” (even if temporary) of the touchscreen. And, most importantly, how! I would never have guessed that a gas stove not only helps with cooking, frying, and grating, but also repairs smartphones.

I'll take it into account. Moreover, I had a similar case earlier. Then I had to change the screen completely. 🙁

Hello, Vitaly! Glad to see you)

I want to say that this method is not a complete solution to the problem, but it is very effective measure, allowing you to revive your phone “here and now”.

You need to find someone’s phone number, they should call you right now or you need to call yourself, you need to send an SMS with congratulations, and then - bam! - touchscreen “blown away!”

It is precisely in this situation that the proposed method of resuscitation is the most effective, and in many cases the only option to get out of a difficult situation.

But then, when the priority issues (urgent call, send SMS, find a phone number) are resolved, then you definitely need to change the touchscreen)

The main thing is not to forget to turn off the gas. 🙂

Yes, yes, you noticed that correctly))

Otherwise, instead of resuscitating the touchscreen, you can empty it family budget on new phone, because now when a phone fails, a person is often left not only without household communications, but also without the ability to fully work. After all, the telephone today for many is the Internet, communication with customers via Viber and a lot more!

I unsuccessfully flashed my smartphone and ended up with a “brick”. Now I walk around with a rarity of shaggy years. 🙂

Well, old phones are sometimes more reliable than the latest models))

Today's ones fell on the floor - everything: the screen cracked, there were scratches. If there are a lot of applications or viruses, the device slows down.

And how it was before... Nokia 3210: even crack nuts, even talk to a friend, even do these two things at the same time - everything works out great!))

By the way, I revived the touchscreen and forgot about this problem for a couple of days. Then he “died” again. I revived him again. Then again. And then, during the next resuscitation using the piezoelectric element of the hob, I received a slight electric shock, and the touchscreen “died” forever. That’s when I had to honestly go to a repair shop and change the touchscreen.

As I said in the article, it is imperative to replace the touchscreen. “Resuscitation” is a temporary measure to “revive” the phone “here and now.” And then the touchscreen still needs to be changed.

What I didn’t expect to read on your site was such a life hack. Although the solution is “dark”, the godfather needs it quick results why not!?

Alexey, of course, this method is just a temporary option. It in no way eliminates the need to visit a repair shop to replace the touchscreen.

However, as a temporary measure, when you need to pull out a desperately needed number from your phone or urgently call right now, this is one of the most effective ways.

And this method helped me. Otherwise I would simply not have mentioned it. I was able to call and get contacts. Twice in this way I brought the touchscreen back to life. But a few days later he died forever.

And I took the phone to the workshop, where within three days (the model is not new anymore) they brought it back to life)

The method really helped. I just took apart the lighter with the piezoelectric element and clicked it on the non-functional part of the screen. The touch worked. Thanks to the author.

Sergey, hello! I write only about what really works, only about what I tried personally)

I'm glad the method helped you. While the phone “comes to life”, do everything you planned (call, copy messages and phone numbers) and then be sure to send it in for repair to replace the touchscreen.

As I already said, the method described in the article is an excellent option for “revitalizing” your phone in the “here and now” format. But it does not restore the functionality of the touchscreen forever. After some time it will stop working again. Then the method I described will help again. Then again. And then the touchscreen “dies for real.” Therefore, do not forget to promptly replace it.

I have a SUPRA M727G tablet, it didn’t fall, I didn’t enter anything, but the touchscreen on the left was broken. Many people on the Internet write that the method with a piezoelectric element works, so I think maybe my platenette is not like that, or they are making fun of me on the Internet :)

The method is 100% not working; personally, not a single method from the network has helped me yet. Of course, the tablet itself is not expensive, it’s easier to throw it away and buy a new one, it keeps one, in perfect condition, it’s a shame to throw it away

Yes, of course, the method presented in the article is not a guarantee of results. Windows 10 has crashed for me, about which I wrote an article “Windows 10 does not start after changing boot parameters: how to fix it without reinstalling the system”, so Microsoft technical support told me a proven method of restoring the system while saving user data, but they immediately made a reservation that There is no 100% guarantee of success.

On the other hand, I always write only about what I have verified from my own experience. It was the method with the piezoelectric element that helped me. I think this works most of the time. It worked for me.

At the same time, the proposed option is definitely temporary. It is designed to revive your device to a short time. But then it must be taken to the service center.

I think in your case you need to do exactly this: if none of the temporary options work, then it’s easier to take it for repair. At least there's no need to throw it away.

Damn, until recently I was sure that this was a scam! Especially when the spark from the lighter did not work on the screen! But she got hit several times metal case, right next door. AND?! Damn, it works. I was amazed. Thank you! It's been a long time since anyone surprised me like that!

Good evening to you, Vasily!

When my touchscreen crashed and I discovered a method using a lighter on the Internet, it was just crazy) That is, it was generally illogical and wrong.

It’s as if I read that to fix a water tap you need to break a glass of red wine on it so that it stops “running.”

And I just decided to try it, because right now there were no other options anyway. I tried it. And the touchscreen worked! To say that I was surprised is to say nothing))

Guys, it really works...

Good evening, Mikhail! Of course it works)

I wouldn’t even think about writing an article if I hadn’t tried this option myself and personally convinced myself that it worked)

I confirm a method for restoring the sensitivity of part of the sensor on an Acer phone

moved a hand-held piezo lighter across the screen to ignite the stove - and for some reason the screen started working

I'm shocked by the way

I hope it works for a long time

Good morning to you, Sergey!

I'm glad that this method helped you. Of course, it is not a panacea and may not work at all in some situations, but in most cases it still works)

But regarding “it will work for a long time” I will say that it is better not to hope. This method is a temporary measure to make emergency calls or to pull a contact from your phone. Then it must be sent for repair.

Congratulations to all those who made it work. After the described procedure, the width of the “insensitive strip” increased from 5 mm to a quarter of the screen.

I was just recently thinking that this method probably doesn’t help everyone, and some people may not get the effect of such a procedure. And then you appeared)

To be fair, it is worth noting that if you decide to resort to the option of resuscitating the touchscreen, then it is no longer working for you. Therefore, using the method presented in the article, you can revive it, but you may fail. But I’m sure you did everything right by trying to bring the touchscreen back to life before taking it in for repair.

P.S. You know, I revived my phone two or three times using the method indicated in the article, after which the width of the “insensitive strip” also expanded to the area of ​​the entire screen. It is quite possible that you have gone too far with the number of contacts of the piezoelectric element with the surface. That is, at some point, resuscitation did occur, but the procedure did not stop, which led to the “death” of neighboring areas of the touchscreen.

Sergey, thank you very much!

When I moved the tablet over the spark, I giggled, but no matter what you do out of despair, the tablet is only six months old, especially since you don’t need to open the tablet, it won’t affect the warranty. As my friend said, explaining why she dyes her hair every month: in life you have to try everything!

You should have seen my stunned face when the dead strip on the touchscreen started working. And I’ve been washing it for a week now!

My wife is grumbling, but I don’t give a damn, after this dance with tambourines, at your tip, I already believe in everything, even that I will find a young, beautiful, rich and deaf-mute woman. Good luck.

Nikolay, good morning to you! If I held a competition for the brightest and funniest post, you would definitely be the winner))

Nikolay, I sincerely congratulate you on the resuscitation of your tablet! And I am very pleased that my article helped you. I’m sitting here all happy and happy and smiling)

I wish you Have a good day and a great mood. However, I am sure that you are always in a wonderful mood. And that's great!

Nikolay, check out my blog. You're always welcome)

That's crazy. I thought it was a divorce. BUT...I don't believe my eyes. Thank you very much, Sergey. I really don’t know how long this will last, but the process itself is amazing.

Good evening to you, Vladimir! I have the same emotions and the same summary (in the style of “Stunning! I can’t believe my eyes!”) was as a result of resuscitating the touchscreen in a similar way))

And as for the timing. After the first resuscitation, my phone worked for several days. Then I brought him back to life in this way. He has worked much less now. And then, when another attempt, the touchscreen has already “died” to be honest.

Vladimir, in any case, this is a temporary measure, but it seems to me that it is the most effective if you need to temporarily return a full-fledged touchscreen, and, accordingly, full phone to life.

I bought a new phone for 20 days, but not in a store and without a warranty, most of the screen at the bottom on the right does not work correctly, for example, instead of the letter 6 it writes 3, it’s dumb, but if I have to change the touchscreen, I’ll try. Thanks for the advice, it’s funny, but after reading the reviews it’s useful.

This is exactly how the touchscreen “dies”. I had the same thing most of the time. First, the “centering” gets lost: I press one number or word, but something completely different is displayed. And after some time, the area where numbers and letters are written crookedly simply dies off.

Valery, I think it’s time for you to change the touchscreen. And before that, you can extend his life using the method indicated in the article.

Thanks Sergey. I did calibration with two applications, but it didn’t help.

Valery, then it’s time to try the method described in the article. If you decide, please write whether it helped or not.

First, I want the service center to check, maybe the cable has come loose, and the sad thing is that there are no touchscreens for it, I looked on the internet and couldn’t find it.

Strange. It seemed to me that everything was on the Internet)

Although, no, I remember I was looking for a charger for one ancient telephone- I never found it.

People, under no circumstances do what is written in that article. A high-voltage pulse can damage the electronics of a smartphone and you will now get a full-fledged “brick”, all these laudatory reviews about the method are fake, be careful with such would-be advisers, they are just trolling you.

Master with many years of experience.

Evgeniy, good day to you!

If you indicated your website or page on social networks, I think many would definitely turn to you for advice. It’s strange, but when searching for your email in “My World,” the page of a woman named Albina, who is 43 years old, pops up. You don't know why this happens?

Evgeniy, it seems to me that in this case You do not advise, but dissuade. In other words, you tell a person in response to his confused question about what to do with a “dead” touchscreen: “Don’t do that.” What should we do? Should I take it to the service? So this is a no brainer!

But the point is that we are considering a situation where we urgently need to call or find a contact. Right now! Otherwise everything! What to do? Your answer: “Nothing can be done.”

Just do it! And I did it. I revived the phone in this way. Moreover, several times. Did I put my phone in danger? Certainly. But the fact is that the phone is already “dead”. A touchscreen is an element of “smartphone electronics”. This element has just been covered. And he needs to be revived. Need it right now! How to do it? The method in the article talks about this.

I tried this method myself and it worked: I revived the touchscreen for several days. Does this method provide a guarantee of recovery? Of course not! I even write in the article that this is not a replacement for repairs, but a chance to bring the phone back to life for a short time.

Evgeniy, I still ask you to indicate your page or website. Otherwise, your message and your regalia - “a master with many years of experience” looks somehow frivolous.

Does anyone know where I can buy a touchscreen for my Leagoo KIICAA Power phone?

Valery, I could be wrong, but it seems to me that everything is available on the Internet, for example, on aliexpress)

Thanks for the tip, it helped a lot, before I couldn’t get a three, it was only a one, now everything is ok

Sergey, good morning to you!

I'm glad that the advice in the article was useful to you. At the same time, do not delay replacing the touchscreen. Next time he may “die” forever)

This method of resuscitation is an effective measure for many, including me. However, this is only a temporary solution. Then the touchscreen must be replaced.

There was the opposite effect, in the evening I put it on exercises, in the morning I picked up the body, and it itself pressed the same current on the wheelbarrow.

It’s impossible to do anything at all, not to call, not to text, there was no gas stove at work and there was no piezo lighter either, but I had a shocker from the Alisha, hit the touchscreen and everything really started to work with a bang, I’m waiting for it to die completely. But the method is cool, I would never have guessed it myself.

Roman, good afternoon! It’s great that you managed to revive your gadget using the method described in the article!

“..I’m waiting for him to finally die...” - I think that we shouldn’t wait for this sad moment. It’s better to take your phone to a service center so that it can serve you for a long time. And if he starts acting up again, you can use “shock therapy” again)

OOOOO. WOW!)))) Thank you very much for the advice, the strip on the left didn’t work, after shock therapy it flies like new)))

Good evening to you, Irina!

It's great that everything worked out for you too)

Respect and respect!)) I’ve been suffering for about a month now similar problem! I would never have thought that it was possible to cure a touchscreen this way, but a miracle happened.)) Thank you!)

Alexander, good evening! It's great that everything worked out for you. And I’m glad that my article helped)

Let me note once again that this method is just a temporary measure that can revive the phone in a situation where nothing else helps. You definitely need to replace the touchscreen with a new one!

Hello. What could cause such a breakdown? The bar on the right doesn't work on my phone. And sometimes it works, but not more than an hour. I'll try tomorrow. Would a piezo element from a lighter work?

To answer the question of what could cause the breakdown, you need to put the phone in the hands of a specialist. There are many reasons: from damage to the board to water ingress.

Of course, a piezoelectric element from a lighter will do. And it is more convenient to use than the piezoelectric element discussed in the article.

I wouldn’t have guessed either, in short, after replacing the touchscreen with a non-original one, the strip on the bottom doesn’t work for me, about 5 centimeters, I used a regular piezoelectric element from a lighter to temporarily install the touchscreen, it’s just that my stove is electric, not gas, but a piezoelectric element can be used and carry it with you just in case, throw it in your pocket, and that’s it))))

Hello, Ruslan! So did you manage to restore the touchscreen? If yes, then I sincerely congratulate you! And traditionally, I will note that this is not an absolute, but a temporary solution to the problem. As soon as you managed to make an emergency call, “pull out” a contact and send a message, it is better to immediately take the phone to a service center and replace the touchscreen.

Ruslan, Happy New Year to you! Good luck to you, success and prosperity!

Happy New Year, too. Of course, I will change the touchscreen, only this time I will install the original one so that there are no dead zones with the motor.

Thank you very much for the tip, about the piezoelectric element, and I forgot to write, people write that they punch the touch, and then turn on the phone, and the sensor works and I don’t turn off the phone at all, and it’s absolutely not necessary for me to spark the entire non-working area /

When I correspond on VKontakte, there is a row of letters on the keyboard. refuse to work, then I just hit one of them with a spark non-working buttons keyboard, sometimes it’s enough once, and sometimes it takes several times until it works, but I hit one of the letters with a spark, at one point, but then the whole row of buttons works, and then the whole keyboard works like that

Ruslan, just on a working device, the moment the spark touches, all the electronics can fail. It can also occur when the phone is turned off, but the likelihood is higher on a running device.

In any case, I'm glad that my advice helped you!)

The most effective way to return your phone to working like it came from the store, and in some cases even better, is to put it in the microwave for 45 seconds. No more, no less, otherwise there are 2 options: 1-it will not be restored and will not help, 2-the display will melt. I myself work in a workshop, suckers pay well for it and carry packs of phones, half of them are restored.

I wonder what you do when your microwave strategy fails and your phone completely fails? The client brings you a phone, the problem of which is that sensitivity has disappeared separate area, and you return the phone to him with a melted display and with the words: “It is beyond repair. Contact another service"?

Kind of weird. I don’t really believe that you work in a service department. It feels like you’ve previously tried to “cook” a phone in a microwave at home, and in half the cases this is exactly the result you achieved.

No, Gagarin, so that not 50/50, but all 95%, you need to remove the magnetron from the microwave and from a distance of 1 m for 90 seconds. irradiate the phone. Yes, required condition: Hold the magnetron with your hands. If it doesn't work out, that is. If you fall into this 5%, you can console yourself with the thought that maybe they will give you a Darwin Award.

Gagarin, you seem to be suckers yourself and are looking for someone to drag you to the workshop. You are the clown, not Gagarin...

Unlike their ancestors, modern smartphones controlled using a touchscreen and several auxiliary buttons. Therefore, it is difficult to imagine a situation worse than the one when the screen on the phone does not work.

This manifests itself in its complete inoperability, loss of part important functions or accidental sensor activations. It is especially unpleasant when a black phone screen catches the user at the most inopportune time.

There are several reasons why your phone has a black screen:

• the device fell;
• the microcircuit has failed;
• the connecting cable flew out;
• moisture has entered the device.

It is almost impossible to immediately understand why the phone screen does not work. The only exceptions are obvious damage that leads to the appearance of cracks on the display or deformation of the case. But first things first.

The phone fell

To damage the display, just one fall of the gadget from a small height is enough. The greatest risk is a collision with asphalt or rocky soil, when the impact falls on a certain part of the protective glass.

If after this, the user’s display no longer works, the glass on the device could have cracked, resulting in damage to the touchscreen along with the display, or the cable could have popped out. It would be reasonable to take the gadget to a specialist for diagnosis, making sure to note that you dropped it.

Screen control chip failure

Another extremely common occurrence is the failure of the graphics chip. The display stops receiving information from the device and no longer shows images. It is extremely difficult to identify this problem at home. In this case, all components must be completely replaced. This operation will not be possible if the device is smashed to pieces.

Worn or disconnected cable

Compared to most hardware components, the cable can be replaced without additional re-soldering of the device board. Usually, solving such a problem takes several hours, even when the cable is completely broken.

It is possible that the display no longer lights up, not because of a broken cable, but because it was disconnected from the main board as a result of a strong impact. Repair work will only take a few minutes, cost varies depending on complexity internal device gadget.

Moisture and liquid entering the phone body

One of the worst scenarios for why the screen won't light up is if the hardware comes into contact with moisture. Whether it's steam or a few drops of liquid, they can cause destruction of board contacts, cause short circuits, or manifest themselves in a specific way when the sensor does not respond to your touch or divide the image into several zones.

The solution to this problem will depend on the amount of oxide formed. If you delay repairs, thorough cleaning may not be enough and you will have to resort to replacing damaged modules.

Oxide Elimination

It is possible to fight oxide on your own. Immediately after moisture gets into the gadget, it is recommended to completely disassemble the device and check it for the presence of electromechanical corrosion. The affected area is treated with 96% medical alcohol to better effect use a toothbrush soaked in alcohol and dry the board.

It’s worth warning right away that such personal intervention can only worsen the condition of the smartphone. It is better to give the device to the specialists, where they will treat it with a water-repellent solution and provide high-quality washing using an ultrasonic bath. Dry it in a heating cabinet at a certain temperature. It is often impossible to say for sure whether the device can be saved due to extensive damage to the hardware of the board.

Advantages of specialized service centers

The obvious advantage is a complete diagnosis of the device followed by replacement of failed parts. Unlike carrying out these manipulations at home, the risk that the master will touch an important unit through negligence is minimized.

Additionally, you will receive a warranty for the entire device, and not for an individual part that had to be replaced. As replacement parts, use only original spare parts without using low quality Chinese analogues.

Rather than try to fix the problem yourself, it is better to immediately contact specialists who have experience in restoring mobile devices and the necessary tools for this. This is especially true for those who need an urgent screen replacement.

Conclusion

The display of a mobile device is very fragile and can be damaged not only due to a strong impact, but also due to moisture getting into it. It becomes almost impossible to save your device without the use of special tools, and in the vast majority of cases, intervention inexperienced user, leads to complete damage to the hardware board or individual modules.

Video

Touchscreen devices have replaced push-button phones. What has changed since this technology became firmly established in our lives? Almost everything that is in any way related to the functioning of the device. That is why a situation in which the sensor stops working requires immediate resolution. Moreover, in many cases a person has almost every chance of restoring his device. We'll talk about this in more detail later.

Why did the sensor stop working?

There are quite a few reasons why the sensor on your phone does not work (what to do is described below). Considering the technology of the touchscreen, as a rule, most often this control element is quite fragile and finicky. Its performance depends largely on weather conditions, damage, and liquid ingress.

If a software failure occurs or the system spontaneously fails to work, problems with the operation of the sensor may occur. These shortcomings are, in principle, conditional and can be easily avoided. We can seriously say that a person is the most important factor in the performance of a mobile device. It is the actions of the owner that will determine how long the device will be in use and why the sensor on the phone does not work.

Common touch screen problems

Often, breakdowns occur due to mechanical damage. If the phone is dropped or deformed, the device will not function properly as a result. Impacts or other mechanical influences can cause various consequences. As a rule, they can be ordinary chips on the lid in best case scenario or a cracked display - at worst. If the deformation of the case does not affect the operation of the gadget in most cases, then the screen will need to be replaced. If the sensor stops working, then you need to pay attention to the components of the mobile device. If the case part moves slightly away from the display and you can notice a gap, then you should immediately take the phone in for repair.

Sometimes a smartphone may stop working if liquid gets into it. Many people have absolutely no idea how water manages to get on the board, but this is a common problem.

Self-rehabilitation

If the sensor on your phone does not work, it is not clear what to do, then first you need to go to the device settings. There you need to calibrate the touchscreen. This feature can often be found in the main settings. These steps can be carried out if the screen is completely in order, the body is intact, and there are no signs of deformation or oxidation. If the sensor has a perfectly smooth surface, then it is likely that the touchscreen has simply turned off.

If the forecasts are not entirely optimistic, the sensor on the phone still does not work, what should I do? It is better to immediately start looking for a solution to your problem. In order to commit the following actions, you need to have certain skills.

Oxide Elimination

In order to eliminate the oxide, you need to use a special tool - a Phillips and flat-head screwdriver. An unnecessary plastic card will also work. You should take alcohol, a toothbrush, an eraser and napkins. Before you disassemble your device, you need to watch a video that describes how to do it. To do this, just type your phone model into a search engine and look at reviews of it.

You need to be careful when separating parts of the housing. There is a risk that a person’s cable may fly off, wires may break, or any parts may break. In order not to get lost with the screws, you need to draw a diagram of the phone and arrange the screws according to the drawing. All accessible places where liquid can get into should be wiped with alcohol, then with an eraser and then blotted with a napkin.

In order to eliminate corrosion of the board, you need to use a toothbrush. Often this is the reason why the phone’s sensor has failed. Where the cables are connected, especially when it comes to the touch screen connector, it is necessary to treat it with alcohol and remove the deposits with an eraser. As a result, the surface will be dry and clean.

If the screen peels off or shifts, then this is probably the problem. Often in such cases the phone’s sensor fails. To put the screen in place, you need to use a hairdryer. You can peel off the touchscreen from the display simply by heating it. The glue will dry, and then it will be easy to move the sensor to the desired location.

The device must be assembled carefully and carefully, installation must be done one at a time. Don't forget about screwing in the screws. It is also necessary to put protective housings back on the microcircuits.

Other methods: how to fix the problem

There are many other reasons why a sensor can fail, so a person’s actions will directly depend on the failure. Sometimes you can solve this problem yourself, remembering that the repair touch phones- an expensive service. For example, if the sensor does not work due to surface contamination and does not respond to touch, then you need to wipe the screen with liquid. You should also use a soft cloth. This is necessary if the question arises about what to do - the sensor on the phone does not work.

If the protective film was installed incorrectly and now the lower part of the sensor on the phone does not work, you need to replace this coating by cleaning the screen from dirt. Dust and dirt often get trapped under the film. This is what makes working with the sensor difficult.

In other cases, the cause may be a software failure. This problem can be easily solved by resetting the settings or flashing the device. In the most in case of emergency should contact the service center. We'll talk about this below.

If the sensor on your phone does not work for no obvious reason

If the sensor stops working for unknown reasons, then it is better to contact the service center and carry out full diagnostics phone. This is the only way to find out the real reason breakdowns and eliminate them without harm to yourself or additional money spent. If the phone is still under warranty, then you can easily replace the sensor or solve the problem itself. As a rule, experts answer the question of why the sensor on the phone does not work quite quickly. This method is the most effective. If a person does not want to harm his phone, it is best to immediately contact the service center as soon as a breakdown occurs. If you are not confident in your abilities, you should not try to decide this problem on one's own.

Results

To summarize, it is imperative to say that the phone should be treated with the utmost care. Replacing the sensor on your phone is quite a complicated process and also expensive. Therefore, it is best to provide your device with the most ideal operating conditions. There is no need to throw it away or treat it carelessly. You should definitely periodically wipe the screen and change the protective film, only then can you really achieve excellent and long-term operation of the touch screen. If the gadget is under warranty, then replacing the sensor on the phone will be a free service.
