The floor touchscreen does not work. Simple tips for those who do not work the sensor on the phone

Doesn't touchscreen work? What to do?

What if you just changed the screen, and he stopped working at all and react to touch?

This is one of the most unpleasant problems, because touchscreen is the main and only option of operation and work with the device.

In the article, we will consider the reasons for this problem, ways to solve it and prevent.

If, after replacing the touchscreen stopped working, then you need to understand what could cause this problem.

Causes of violations in work

Accumulation of garbage inside the device;
Problems with connectors;
Crookedly planted display;
During replacement, the screen damages damage;
Damage or impulse of the loop.

Ways to solve the problem

The problem is serious, but, like any other, it has a solution. These problems may occur if on your device a liquid crystal screen.

Try to restart your gadget. Most often this method is triggered.

If the reboot did not solve the problem, perform full reset Devices. In this case, your personal data will not be lost. How to do it? Each device has its own special combinations that differ from others. Therefore, you need to see the instructions for your gadget or search it on the Internet.

If the touchscreen has not earned the first time - this is not a reason for panic. After all, it can be in incorrect installation Sensor, if the wizard made an error in touch sensor with the screen.

Here the device needs to be opened to check it out. First of all, remove the protective cover of the screen, because the reason may wage in it.

Tip:

do not hurry with the removal of the lid and disassembling the device, if you have not yet checked the screen performance without internal intervention.

Checking the loop

If it is connected not tightly to the display, then it is necessary to reconnect and check the performance.

You must also check the contact with the contacts, whether they are inserted to the end.

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

But if there are any visual damages there, but it needs to be replaced.

With a short connection of contacts, there are incorrect triggerings of the press or the screen may not work at all. You should disassemble the device, insert a loop well and collect back.

If the contacts are sold by other contacts, for example, from the connector, the loop must be inserted until it stops and pull out one tenth millimeter so that the train stood on new points of contact.

This happens that the controller sold on the loop turns out to be incompatible with your version. This often happens with gadgets from China.

Then you need to drop a kotroller from your old display and get it into a new screen.

If you yourself can't do this, because of the absence of experience - take the masters that are dealt with.

A protective film is pasted on the display. If it is poor quality, it will affect the operability of the screen by reducing the sensitivity to contact. Therefore, remove it and wipe the screen with a special napkin.
Calibration is required. Try to enable your device without sensor application so that the controller can rewrite the new screen data. During the download, its firmware will be updated and the system starts after the update.

Such a procedure is called screen calibration. It is used with a strong and weak sensitivity of the screen, as well as with the complete absence of sensitivity.

Basically, the calibration is made through special applications.

Modern gadgets have become an integral part of our lives. The phone is the most common gadget. It is almost every person. Unfortunately, even the most reliable phones can break due to shocks, water or software failures. The most common problem with many users of mobile devices are faced - the sensor does not respond to touch. If the device is still under warranty, then you should immediately contact service center. Otherwise, it is not worth a hurry, because there are cases when the problem can be easily eliminated. The sensor does not respond to touch, what to do in this case? Let's consider all aspects of this problem.

Repair of the phone screen

Before resolving the problem, you must make sure that the reason for the breakdown of your display. This may be mechanical damage, entering the liquid inward the device or software failure. If you are confident that you did not drop the phone or did not shed liquid on it, you can assume that this is a program failure.

Clearing Mobile Phone Screen

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

We take suitable tissue and liquid to clean the screen. It is better to use a lint-free or any other natural fabric. To clear the display, we will need a means for cleaning points or monitors.

If this method does not help, then it is necessary to move to the following actions. Of course, they can also not help. The true cause of breakage can only be installed professional, but it can decide not every problem.

Program failure, which led to a displays breakdown

If display mobile device places react to your touch, then you can try to make Hard Reset. Systems, this is a complete reset of settings. But it is worth remembering that it can help only if the sensor is from time to time it is buggy. After resetting the settings, install the applications that can be cleaned. system registry. This will eliminate errors caused by rAM. Recommended applications - WinFixer and Cleaner4. Unfortunately, the second utility is paid, but has a good functionality. The first program will suit you if you are not sure why the display does not respond poorly to touch, and you are not going to spend money.

All actions should be done without a memory card. There may contain viruses that cause failures in the system. After resetting the settings and cleaning the registry, you must install an SD card in place and check the device with antivirus. Select a complete device check and expect. But after the actions performed, the sensor does not respond to touch. What to do? In this case, you need to proceed to replacing the sensor, since the reason is caused by a non-software failure.

Mobile Phone Display Replacement

The sensor does not react to touch - what to do? If the previous methods did not help, then you need to change the damaged display. Most often it should be done when the device fell, cracks appeared or moisture hit. In the latter case, you may not even notice how the fluid got into the phone, as this can happen due to the change of temperatures. So, condensate, which accumulates in a mobile device, will interfere with the normal operation of the phone. First, black spots may appear when working with a gadget, and in the future the sensor itself will stop responding to touch. In this case, you will need to change the screen.

Repair of the phone screen is not too complex process, the main thing is attentiveness and accuracy. This can accomplish any person. The sensor does not respond to touch - what to do? You must first disassemble your device, but you should remember the sequence of actions so that there are no problems with the assembly in the future. All plugs and latches are removed using a fine item. You will need to carefully remove all the elements from the latch.

After disassembling your smartphone, you must 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 pCB different ways. There is a contact method, while the sensor is simply disconnected, and wired. In the latter case should be very neat.

If you need to respond to the matrix from the sensor, it is necessary to follow such recommendations:

First, heat the surface up to 60 degrees. This can be done using a regular hair dryer. It is evenly dispersed to warm up so that the glass is not cracked, and the glue is heated.
Next, you need to find a flat and thin object to easily disconnect the sensor from the matrix. To do this, we simply use the edges and gently raise.

It remains only to attach a new sensor. How to do it? Included, the sensor and glue should go. First we apply special glue, and then carefully attach the sensor.

The cost of the new display

How much is of course different models Smartphones screen cost will be different. On average, to change the display on phones with a diagonal of 4.5 or 5 inches, it will be necessary to give about 700 rubles.

If you do not want to disassemble the phone yourself, you can contact a specialist. For the master asks about 2,000 rubles. Although this procedure is not very complex and can be changed independently. Only to this will need to be suitable carefully and carefully.

Do not work touch buttons

The lower sensory buttons directly belong to the screen and in case of their failure, it is necessary to do all the actions that we have already considered. If the touch buttons do not work, you must first make a complete reset of settings. Next, clean the system registry and check your device for viruses. Unfortunately, if the actions did not help, it will be necessary to change the screen.

Modern mobile devices cannot be submitted without touch screens. Therefore, decide what to do if the sensor does not work on the phone, it is necessary only after studying the events that led to the breakdown. The screen is the main part of modern smartphones, without which they lose all functionality.

In order to find out why the sensor does not work on the phone, you will need to carefully examine the smartphone. Sometimes the problems in the phone are visible to the naked eye, for example, if the screen is broken, and in some cases, the performance can be lost without reasons. Moisture entering, rough mechanical impact and much more can affect the condition of the apparatus.
If the source lies in the software failure, then the situation may be observed when the gadget reacts incorrectly to your touch. There are such problems often because of the action of the host itself, which by negligence or inexperience, made changes to the operation of the system.

Typical touch screen faults

The most common reason why the touchscreen does not work is mechanical damage. Blowing and other impacts can lead to negative consequences. The most neutral will be chips, seriously problems will appear in the formation of a "cage", in which the device can continue to function.

As modern smartphones Quite fragile devices, even after falling from the height of human growth, it stops working. If the device continues to function, and damage is applied in the form of formation of slots in the case or its deformation, cessation of the work of the screen, then it is necessary to contact a specialist for repair work as soon as possible.

Another popular cause is moisture. Despite the fact that the device looks like a monolithic device, it has small gaps and gaps through which the fluid hits the main fee.

Moisture and fluid getting into the phone body

Moisture getting into cellular mobile leads to the beginning of the contact oxidation process and fee. If the gadget fell into a similar situation, then it is not necessary to disassemble the smartphone without much. The first thing to be done is to dry the device. If the drying did not give the result, it should be attributed to a specialized repair center, which is especially concerned with expensive models, the intervention in the internal scheme of which leads to irreversible consequences. During the repair, you can use cheap replacement of the device that will receive calls and SMS.

Elimination of oxide

In some cases, after the moisture fell inside the gadget, after a certain time it will start to work, but poorly or incorrectly. In this case, you can try independently eliminate the oxide, which occurred when contact with the liquid.

To do this, you will need a tool with which the oxide will be removed (card from plastic, screwdriver, and so on). Also necessary: \u200b\u200balcohol, toothbrush, eraser and napkins. Before analyzing the smartphone, you need to get acquainted with the instruction that can be found on the Internet.

The cleaning procedure should pass carefully, since any awkward movement can lead to an additional breakdown. The disassembled gadget must be folded onto a sheet or a napkin in such a way that it can be easily assembled, as in the drawing. Every place you need to wipe with alcohol, eraser and flush with a dry napkin.

If traces of rust were found, it is eliminated with a toothbrush. The place is processed with alcohol, the remaining corrosion is removed by the eraser.

It is especially difficult to have in cases where the reason has become a sweet drink. The impact of such a mixture has a chance to derive a gadget, and without the intervention of a mining specialist will be impossible.

Spain display

If the display has occurred without damaging the screen, it is necessary to just thoroughly wipe the sensor with a cleaning fluid, then remove the remaining moisture with a dry cloth. To save the display it is recommended to use protective filmwhich is easy to glue and removes in case of contamination.

Plurif damage

Damage to the device of the device is one of the reasons for a breakdown that cannot be eliminated at home. Therefore, if the sensor sometimes works incorrectly, it is worth contacting a specialist who can with the guarantee can restore the device's performance.

Software failure

Reload the smartphone. In some cases, the changed settings of the software will not be applied after rebooting the system.
Take advantage of the built-in program for testing the sensor. To do this, you need to enter a combination that is unique to each brand apparatus.
Check the temperature temperature and place the machine into favorable conditions.
Check the operation of the memory card and SIM card.
Download the gadget in safe mode.

In some cases, the problem can be solved by these simple ways. If attempts did not give any fruits, then it is necessary to turn to the masters.

For changing push-button numbers Sensory devices came. What changed after this technology firmly entered our lives? Almost everything that is in any way associated with the functioning of the device. That is why the situation in which the sensor stops working, requires instant permission. Moreover, in many cases, a person has almost every chance to restore its device. Let talk about it in more detail below.

Why the sensor stopped working

The reasons why the sensor does not work on the phone (what to do is described on), quite a lot. Given the manufacturability of the touchscreen, as a rule, most often this element is rather fragile and picky. Its performance is maximally dependent on weather conditions, damage, as well as fluid entering.

If the program failure or spontaneous failure of the system work, problems with the operation of the sensor may appear. These shortcomings, in principle, are conditional, they can be easily avoided. It can be serious that a person is the most important factor in the working capacity of the mobile device. It is from the host actions will depend on how long the device will run in operation and why the sensor does not work on the phone.

Typical touch screen faults

Often, breakdowns are formed due to mechanical damage. If the phone fell or deformed, the device will work incorrectly as a result. Due to blows or other mechanical stress, various consequences may occur. As a rule, they can be ordinary chips on the lid at best or the selected display - at worst. If the deformation of the case does not affect in most cases to work the gadget, the screen will need a mandatory replacement. If the sensor stopped working, then you need to pay attention to the components of the mobile device. Is there a body part slightly moves away from the display and you can notice the gap, then you should immediately carry a phone for repair.

Sometimes the smartphone can stop working if liquid falls into it. Many are completely incomprehensible how water is managed to get on the fee, but this is a common problem.

Independent rehabilitation

If the sensor does not work on the phone, what to do is not clear, then you must first go to the device settings. There you need to calibrate the touchscreen. Often this feature can be found in the main settings. These actions can be carried out if the screen is completely in order, the housing is whole, there are no traces of deformation or oxidation. If the sensor has a flawless smooth surface, it is likely that the touchscreen simply turned off.

If the forecasts are not quite optimistic, still does not work the sensor on the phone, what to do? It is better to immediately begin to find a solution to your problem. In order to make the following actions, you need to have certain skills.

Elimination of oxide

In order to eliminate the oxide, it is necessary to use a special tool - this is a cruciform and flat screwdriver. An unnecessary plastic card is also suitable. You should take alcohol, toothbrush, eraser and napkins. Before disassembling your device, you need to watch the video, where it is described how to do it. To do this, it is enough just to dial the model of your phone in the search engine and see the reviews on it.

You need to be careful when disconnected parts of the case. There is a risk that the person can fly the train, break the wires or break any details. In order not to get lost with the screws, you need to draw a diagram of the phone and decompose the screws according to the drawing. All available places where liquid can get, you need to wipe with alcohol, then the eraser and then flush the napkin.

In order to eliminate corrosion of the board, you need to use a toothbrush. Often this is the reason that the phone sensor refused. Where the plume connection occurs, especially when it comes to the connector touchscreen, It is necessary to handle alcohol and remove flair by eraser. As a result, the surface will be dry and clean.

If the screen displays or offset, then the problem is exactly in this. Often in such cases refuses the phone sensor. In order to put the screen in place, you must use a hairdryer. You can unscrew the touchscreen from the display by simple heating. The glue will freeze, and then it will be easy to shift the sensor in the right place.

The device must be assembled carefully and carefully, the installation must be alternate. No need to forget about screwing screws. It is also necessary to put the protective buildings back on the chips.

Other ways: how to fix the problem

There are many other reasons for which it may refuse the sensor, so the actions of a person will be directly dependent on the failure. Sometimes it is possible to solve this problem independently, recalling that repairs touch phones - Expensive service. For example, if the sensor does not work due to surface contamination and does not respond to touch, then it is necessary to wipe the screen with a liquid. You should also use a soft napkin. It is necessary if the question arises about what to do - the sensor does not work on the phone.

If the protective film was incorrectly installed and no longer works bottom part Sensor on the phone, it is necessary to replace this coverage, clearing the screen from contaminants. Often dust and dirt fall under the film. That is what makes it difficult to work with the sensor.

In other cases, the reason may fail software. Easy to solve such a problem by resetting or flashing the device. In the most emergency cases Contact the service center. Talk about it below.

If the sensor does not work on the phone without explicit reasons

If the sensor stopped working for incomprehensible reasons, it is better to contact the service center and carry out full diagnostics of the phone. Only so you can figure out the true cause of the breakdown and eliminate without harm for yourself and additional money spent. If the phone is still under warranty, you can easily replace the sensor or solve the problem itself. As a rule, the question of why the sensor does not work on the phone, experts respond 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 the breakdown appeared. Do not, if there is no confidence in your abilities, try to solve this problem yourself.

RESULTS

Summing up, you must definitely say that the phone should be treated as careful as possible. Replacing the sensor on the phone is a rather complicated process, as well as expensive. Therefore, it is best to provide your device as ideal conditions for work. No need to throw it or relate to it inactively. Be sure to periodically wipe the screen, change the protective film, only then you can really achieve excellent and long-term operation of the touch screen. If the gadget is warranty, then replace the sensor on the phone will be a free service.

Screen on the phone?

Components of electronic devices may be damaged if they use them carelessly. If part of the touch screen does not work on the phone, it can be caused by both the temperature mode of use and mechanical damage.

Repair of a smartphone or tablet with an insensitive touch screen will help cope with serious problems. Sometimes it helps a simple cleaning in combination with disassembly. However, if after all user actions, the device does not turn on, it must be transferred to the service, and this can lead to additional costs.

Causes of fault

You can select the following reasons for which the part of the screen does not work:

Oxidation of contacts due to condensation. Moisture that fell inside the device may cause To full or partial loss of working capacity. Oxidized contacts cease to respond to processor commands and transfer them to the screen. To eliminate the effects of fluid entering, you need to disassemble the device and clean internal components. To do this, you can use alcohol applied on your cotton swab or tampon. After this procedure, the phone should be included in the usual mode.
Cracks on the screen surface. Because of the micro-damage of the sensor, it stops responding to pressing. There are such damage due to fall or shocks on the screen. It is possible to determine the cracks on the display by carefully studying its surface. If part touchscreen Covered with cracks, you can restore performance, replacing the device touch screen.
Disconnect the touchscreen contacts as a result of offset. It usually does not work in the lower or top half of the screen. To diagnose contact offset, you need to disassemble the device and check whether the visual order of symmetry of the components is not disturbed. If you see contact displacement, you can try to fix them with tweezers. In addition, some elements are attached to glue, which can melt at high temperatures and exhibit contact. In order for the upper part to return to its place, you need to heat the holder with a hairdryer and return the component to its original position.

Features of electronic devices

In addition to these failures electronic devices May begin failure due to internal architecture. Restricting the size of the component affects the dispersion of the power if the tablet screen does not respond to the touch - this may be associated with the overload of the device with a large number of resource-intensive applications. To prevent, you need to start the task manager. Find out what the processor loads, and disconnect unnecessary applications.

Electronic devices increased the sensor sensitivity of the screen. Situation when screen A tablet or phone does not work, can be associated with banal pollution. Attaching lubrication and dust to the surface leads to the fact that the tablet does not respond to touch.

If the screen does not work on the screen - better decision It is sending it to the Diagnostic Service Center. Most models have a very long warranty, which will replace the device without any costs without defects or refund. If it is not guaranteed, you can simply just buy a new gadget and take care of it later.
