There are two main categories of reasons why the screen on a tablet does not work - due to mechanical damage or due to a software glitch. With the first category, everything is clear - if your device is dropped or someone damages it, the screen on it cracks, as a result of which it stops working correctly. The second category of reasons is more difficult to diagnose, but it is much easier to deal with this kind of problem.
Thus, users quite often complain that the screen has stopped working and does not respond to touch in any way after charging, installing new applications on the device, or visiting any websites. All these problems are caused precisely by software failures, which, unfortunately, happen on devices running the Android operating system quite often.
If there is no mechanical damage to the screen, but it does not turn on, you need to perform a number of simple steps that can help “revive” your device. Step one is to unplug the battery, wait 30 seconds and put it back in place. You can remove the battery from the tablet by simply opening the back cover of the device. This procedure is necessary because it allows the system itself to reboot and theoretically can eliminate a software failure.
Step two - reset your device to factory settings. You can do this even if the touchscreen of your tablet does not respond to touch. Here you should be warned that the instructions below are typical for most tablets, but not for all, so you should first find out how to hard reset your device. Before resetting the settings, you must turn off the tablet and, just in case, remove the memory card and SIM card from it.
Next, press the volume up key and the power button at the same time. After these manipulations, the device should vibrate and a menu will appear on the screen. In this menu, use the volume keys to select “Settings” and then “Format system/Restart Android”. After this, your device will begin to reboot, and all settings and programs that were installed on it will be deleted.
Step three - reflash your tablet. If the first two manipulations did not help, and the screen still does not work, but is not mechanically damaged, then flashing the firmware will help. Most users are scared by this word, but in fact there is nothing scary about it, since it only means reinstalling your operating system - just like on a PC. If you have never flashed your tablet, then it is better to ask someone more experienced to do it, so as not to completely “kill” the device.
If the tablet screen does not work due to mechanical damage, which includes not only cracks, but also damage to the cables, then it should be replaced. It is worth noting that replacing the screen on a tablet should be done as quickly as possible, even if it works. This is due to the fact that if there are cracks, after some time not only the touchscreen, but also the matrix may fail, and replacing it will cost much more.
At the same time, it is highly desirable that the tablet screen be repaired by specialists, since if you try to do it yourself, you can only aggravate the situation. Thus, if there is mechanical damage on the display of your device, the best solution would be to contact service centers or companies that provide repair and maintenance services for mobile devices.

If there is no display backlight on the iPad, this does not affect the performance of the tablet in any way, but it significantly reduces its ease of use. The lack of backlight or its weak operation does not allow you to fully use the iPad in the dark or in bright sunlight - you simply cannot see the image on the screen. This small flaw makes the tablet completely useless in most cases, but it's an easy problem to fix yourself.
LED backlighting is necessary in order to comfortably view texts and images on the tablet at any time of the day and in any lighting. If the light bulbs do not work correctly, this significantly reduces productivity when working with the gadget. The lights are located below the display. Most often, the problem with the LED backlight lies in the settings of the tablet itself. Therefore, it is not necessary to immediately take the device to a service center.
This problem often occurs among Apple users, and you can solve it on your own by following simple recommendations.
If the display backlight does not work, you can try to determine the cause yourself and fix the problem. The main reasons for the lack of backlight on an iPad of any model can be called:
If the cause is an incorrect brightness setting, the problem can be solved very easily:
If there is no damage to the internal elements, the problem should go away.
If the brightness settings are fine and set to the parameters you want, but the LED backlight still disappears, there may be another problem. Most minor problems with Apple technology can be resolved by hard rebooting the device. Therefore, if you discover any problems in the operation of the gadget, you should immediately do a hard reboot. If there is no display backlight, this method may also be useful.
To do this, you must follow the following scheme:
Most often, such a reboot quickly restores the faulty backlight. If this does not help and the problem does not go away, check whether the “auto-brightness” function is turned on, and also update the tablet to a new version according to the scheme specified by the manufacturer. Lack of updates is a common cause of many problems with Apple tablets. Therefore, you should update the software version to the latest version every time your device prompts you to do so.
If the backlight has disappeared, and the above tips did not help and the image is also not visible, remember the last manipulations with the device. When the tablet falls, the light stops working and the cable and fuse are damaged, even if there are no visible damage to the gadget. The problem is solved by replacing the fuse or the iPad display cable.
Also, a problem with the LED backlight can occur after you spilled something on the tablet and the liquid flowed inside, flooding the fuse. First of all, dry the device thoroughly, then restart it and try setting the light again.
The absence of backlight after repair or replacement of the display indicates poor-quality repair work. For example, you decided to change the display cheaper from an unverified technician who did a poor job. It will not be possible to correct such work without the help of a qualified specialist.
Only a professional technician can competently solve such a problem if a hard reboot of the tablet does not help, and all settings are set correctly. The technician will perform diagnostics and determine the problem in the loop or fuse. In particularly difficult cases it will be necessary.
If the display backlight does not work on an iPad of an old or new model, and you have taken all the steps to fix the problem yourself, you should contact a technician for help. Specialists registered on the YouDo website:
When there is no display backlight on the iPad, fill out an application and receive favorable offers from masters registered on the Yudu website.
There is no picture on the screen, it is dark and does not work. Various circumstances can contribute to the appearance of such a defect. For example, if the device does not charge or the power circuit fails, and the user does not know about it, he may decide that the problem is in the screen. Try to find the "Reset" button and reset the settings to factory settings. Of course, the issue could be in the display itself, but in this case, most likely, we are talking about a hardware failure. If the backlight is on when you turn on the device, but nothing else happens, then the problem lies in the screen. Take the tablet to a service center for diagnostics. It may need to be replaced.
The image on the display is distorted or shows cracks or chips. Shocks and falls are the main enemies of mobile technology, so if the tablet’s screen does not work, think that maybe the device was dropped or moisture got into it. If such a problem really happened, then most likely the screen will have to be replaced with a new one. But you need to carry out diagnostics first, since only the protective glass may be damaged. The cost of replacement in this case will be much less.
There is an image, but it is impossible to unlock the tablet or the screen does not respond to commands. Carefully inspect the device: if scratches, cracks, darkening or other defects are visible, then the resistive layer may be damaged or delaminated. In this case, most likely, replacing the touch glass or replacing the touch glass controller will help. In addition, such manifestations often indicate software failures, virus penetration, etc. If there is a picture, but the tablet screen does not work, try resetting the settings. Reflashing the device can also help, but doing it yourself is not recommended.
If you are not an electronics specialist and do not have relevant experience, then it is better to entrust tablet repair to professionals. Even if the tablet screen does not work due to a software glitch or a simple replacement of the protective glass is required, only a specialist will return the equipment to working order in the shortest possible time.
There are two main categories of circumstances why the screen on a tablet does not work - due to mechanical damage or due to a software failure. With the first category, everything is clear - if your device falls or someone damages it, the screen on it cracks, as a result of which it stops working correctly. The second category of circumstances is more difficult to diagnose, but at the same time it is even easier to cope with this kind of problem.
Thus, users quite often complain that the screen has stopped working and reacts in any way to touches after charging, installing new applications on the device, or visiting some websites. All these problems are caused specifically by software failures, which, unfortunately, happen quite often on devices running the Droid operating system.
What to do if the tablet freezes!!!
If there is no mechanical damage on the display, but at the same time it does not turn on, you need to perform a number of common actions that can help “resurrect” your device. Step 1 - Disconnect the battery, wait 30 seconds and return it to its place. You can remove the battery from the tablet by simply opening the back cover of the device. This function needs to be implemented, as it allows the system itself to reboot and, on a theoretical level, can remove a software failure.

Step 2 – reset the device options to industrial. You can do this even in this case, if the touchscreen of your tablet does not respond to touches. Here it should be warned that the following summary is typical for most tablets, but not for all, so you should first find out how to do a hard reset specifically for your device. Before resetting the options, you need to turn off the tablet and, just in case, remove the memory card and SIM card from it.
Next, press the volume up button and immediately press the power button. After these manipulations, the device should vibrate and a menu will appear on the display. In this menu, use the volume buttons to select “Options” and then “Format system/Reboot Droid”. After which your device will begin to reboot, and all options and programs that were installed on it will be deleted.
Step 3 – reflash your own tablet. If the first two manipulations did not help, and the screen does not work as before, and is not mechanically damaged, then flashing will help. Most users are afraid of this word, but essentially there is nothing terrible in it, since it only means reinstalling your operating system - the same as on a PC. If you have never flashed your own tablet, then it is better to ask someone more experienced to do it, so as not to completely “destroy” the device.
If the tablet screen does not work due to mechanical damage, which includes not only cracks, but also damage to the cables, then it should be replaced. It should be noted that replacing the screen on a tablet should be done as quickly as possible, even if it works. This is justified by the fact that if there are cracks, after some time not only the touchscreen, but also the matrix may fail, and replacing it will cost even more.
With all this, it is very better for the tablet screen to be repaired by specialists, since if you try to do it yourself, you can only worsen the situation. Thus, if there is mechanical damage on the screen of your device, the best solution would be to contact service centers or companies that provide repair and maintenance services for mobile devices.
Components of 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 simple cleaning combined with disassembling the case helps. 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.
There are the following reasons why part of the screen does not work:
In addition to the listed breakdowns, electronic devices may begin to malfunction due to the peculiarities of the internal architecture. Limiting the size of components affects their power reduction if the tablet screen does not respond to touch - this may be a consequence of overloading the device with a large number of 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.
If the screen on your tablet does not work, the best solution would be to 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 a new gadget and subsequently treat it more carefully.
When our devices malfunction, we try to solve the problem as quickly as possible. Before going to the service center, you should check your tablet yourself. Sometimes the cause of defects in operation is software glitches, this also applies to the screen. In this short review, we will touch on three common problems faced by tablet owners:
IMPORTANT! We remind you that you can try to solve software failures yourself; only professionals from service centers should deal with hardware problems.
Failures in the operating system may be the cause. During normal operation, the screen begins to darken when inactive - this allows you to save battery power. If the display gets darker while playing, watching a video or browsing the Internet, then it’s time to restart the device. It’s better not to take on the task of updating the gadget’s firmware yourself.
In the case when the screen gets darker and then gets brighter again, it’s worth checking the matrix. It may be malfunctioning; replacing the part will help here, since the matrix cannot be repaired.
Here, too, there can be two options - a software failure or hardware failure. First of all, go to the settings of the application that is responsible for power. If all indicators there are set to a minimum, then the screen will not be able to work normally during games or videos.
The cause may also be an OS failure; in this case, it is recommended to restore the original firmware of the device. As for mechanical damage, flickering usually appears due to the cable - it can come off or become damaged.
If this problem occurs when working with certain programs, then you should remove them and check the result. Also, some users solved this problem by doing a full reset (all data on the device is deleted). If the screen goes out when in contact with the tablet, and lights up again when you press the case, then this is mechanical damage. Most likely, the problem can be solved by securing the cable.
