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 some important functions, or random triggering of the sensor. 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 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 take only a few minutes, the cost varies depending on the 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

Has an obvious advantage full diagnostics device with subsequent replacement of failed parts. Unlike carrying out these manipulations at home, the risk that the master will touch important node by negligence is reduced to a minimum.

Additionally, you will receive a warranty for the entire device, and not for separate part, which had to be replaced. As replacement parts, only original spare parts are used, 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

Display mobile device it 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 using special tools, and in the vast majority of cases, the intervention of an inexperienced user leads to complete damage to the hardware board or individual modules.

Let's look at the problem when, when you launch an application or game on Android, a white/black screen appears and no further loading occurs. It feels like the phone/tablet freezes when turning on the game.

This article is suitable for phones and tablets of all Android device manufacturers: Samsung, LG, Sony, Huawei, Xiaomi, HTC, ZTE, Fly, Alcatel and others. We are not responsible for your actions.

On Android devices, a problem may appear that causes emotions similar to those when the user personal computer sees on the monitor " blue screen Death" for Windows. Similar situations happen with inexpensive gadgets and with flagships.

If a message appears on the screen of your tablet or smartphone White screen If you launch an application and you don't know what to do, then you shouldn't worry. Let's take a closer look at the problem and consider ways to resolve the situation.

The following causes of malfunction are identified:

• A new application was recently installed.
• Unsuccessful attempts were made to flash the device's firmware.
• Device long time was in a very dusty room.
• The gadget could have fallen into the water, which is why it happened short circuit or corrosion of elements (when some time has passed after the fall).
• Impacts or falls can cause mechanical breakdowns, which is often preceded by the formation of white stripes.

The main reason is insufficient quantity random access memory gadget, which when launching the application is necessary to load it. When users use different applications, then when they are turned off they go into background mode and look forward to further work. To ensure they load faster next time, applications in RAM retain their work.

Increase

From this we can conclude that you should clean the RAM before downloading applications and games so that they can turn on normally without a white screen. You can press the corresponding key, after which it will delete all active applications.

The screenshot shows the Android interface on a Samsung smartphone, where cleaning is carried out special key bottom right. The process for other manufacturers is not much different; they have corresponding cleaning buttons.

You can also clear your device of running background processes using the Smart Manager utility.

Increase

Go to the “RAM” section and click on “End All”.

Increase

As a result, you will be shown how much RAM is freed up, and your smartphone will immediately start working faster. This application disables all unnecessary background processes happening on your device. All important processes work will continue so as not to harm the device. After these manipulations, the application should load normally, without a white screen appearing.

In some situations, the cause of the white screen is a recent installed application. The appearance of a white screen and the device freezing when opening or closing a program may indicate that the device simply does not have enough internal memory. In such a situation, the user will need patience.

• Checking how much is open running applications, close all unused ones.
• Let's see how many tabs are open in the browser. They need to be closed.
• We clear the desktop of unnecessary widgets and shortcuts.
• We move frequently used programs to the built-in memory from the SD card.

A white screen appears after the gadget falls

The display most often stops working due to mechanical damage. Drops or impacts can damage the matrix or other parts of the board. In such a case, the device’s display may stop working altogether. Self-replacement parts and repair is a task that not every user can cope with, which is why it is strongly recommended not to experiment with disassembling the device, but rather to take it to a service center.

It often happens that the screen shows White color, because the cable has become disconnected or damaged. On older devices, the contacts may oxidize and become dirty. Advanced users can clean them with an eraser, which will be quite enough. It is important to remember that opening the gadget yourself will void its warranty.

Increase

A damaged display is not yet a reason to choose and purchase new gadget. Such components can be easily replaced without special equipment, even at home. In chapter technical support or on the forums are available detailed instructions for parsing the desired model products.

If the cause cannot be determined

Sometimes it happens that the user simply restarts the phone, but the gadget does not turn on, the system does not boot, and only a white screen is observed with no signs of activity. Sometimes technology can malfunction.

You can try all known methods to reboot the device. If such a reboot does not help, then remove the battery and turn off the power. You also need to remove the SD card. After a short break, you need to start the gadget again.

After completing the manipulations, is a white screen still displayed? This means that it is worth resetting the gadget to factory settings, although information will be lost because of this, but the functionality of the device can be restored.

Unlike push-button telephone, the smartphone is controlled by touching certain points on the screen.

If it starts to work incorrectly or stops functioning completely, it becomes impossible to control the device. Let's look at the main types of faults and steps to eliminate them.

The display responds erroneously to touch

For example, you click on on-screen keyboard one letter, and the adjacent one is entered. This means that the sensor needs to be calibrated. This problem can occur after minor impacts or a small hit.

Sensor calibration can be done on any smartphone - read ours. After launching it, crosses are displayed on the screen, clicking on which “trains” the sensor.

The display is on but does not respond to touch

There can be many reasons for this malfunction. The most common is a lack of smartphone RAM. This happens when the user opens many applications at the same time and the device freezes. A simple reboot of the gadget will help here.

Screen contamination

The next reason is screen contamination, which occurs due to fingerprints and wet hands. In this case, it is enough to wipe the display with a damp cloth. There are deeper contaminations when moisture gets between the glass and the sensor. Before taking your phone to a service center, you should try drying it with a hairdryer, but without too much heat.

Often such a malfunction appears when the phone is used outside in winter or in the heat in summer. or overheating. As a rule, when the ambient temperature normalizes, the viability of the screen is restored.

The display does not turn on, but the phone works

In such cases, the smartphone can even receive incoming calls. This malfunction also occurs for many reasons, but it is unlikely that you can fix it at home on your own. The fact is that such symptoms indicate serious and deep problems.

One of possible reasons- problems with the display cable. The cable is a flexible strip with conductive tracks that connect the display to the screen control chip. Sometimes, due to a fall or impact, the cable simply becomes detached - in this case, it is enough to return it to its place. Often moisture or dirt gets under the contacts of the cable - cleaning the contacts can solve this problem. If the cable is damaged, it must be replaced.

Replacing the display

We looked at the simplest and most cost-effective faults. If the cause of the breakdown is the screen control board, or the display itself needs to be replaced, you need to think about the feasibility of such a repair, since its cost is often comparable to the cost of the smartphone itself. Judging by numerous videos, the process of peeling off the touchscreen from the glass for subsequent replacement does not seem difficult and it may seem that anyone can do it. But the statistics service centers says the opposite - too many new faults arise after home repairs.

If simple activities They didn’t give me a way to restore my smartphone screen positive result, in order to avoid additional costs, it is recommended to contact a specialized service.
