The tablet streaks the screen. The tablet display does not work - reasons and repairs. The display cable has come loose from the connection socket

One day, stripes and ripples of unknown origin may appear on your favorite tablet. What is it and how to deal with it?

The data cable is worn out or has come out of its socket

This most often happens after the tablet falls or hits hard objects. In this case, no physical damage is visible on the display; there are no cracks, illuminated areas or spots. During sudden shocks, the display's connecting cables may “jump out” of the socket. To restore the functionality of the device in this case, just press on the cable and push it tightly into the socket. True, when disassembling the tablet, you should be careful not to inadvertently touch any other elements, because this is a fairly miniature device with small spare parts.
In rare cases, the loop simply refuses to transmit data as it should. In this case, a trip to the service center cannot be avoided. Although replacing a cable is usually inexpensive.

The display (matrix) was damaged

When dropped, the most common damage is physical damage to the matrix or protective glass. Such damage is expressed in the appearance of stripes and ripples on the tablet screen, which appear immediately after a fall. Even more obvious symptoms are tangible or visible cracks and stains. It’s unfortunate, but you won’t be able to fix such problems on your own. The display or matrix will need to be replaced at a service center, which will cost a pretty penny. The price depends on the screen size and tablet model.

Software glitch

If ripples, stripes, unnatural color distortion, or other types of inappropriate behavior (overlaying several pictures on top of each other, etc.) appear on the tablet screen, the cause may be a software glitch. In such a situation, you can try resetting the tablet to factory settings or an even more radical method - a complete flashing.

Normal tablet operation with occasional freezes during which image artifacts appear
Due to poor cooling, tablets can overheat, and in such conditions the video chip often cannot cope with its responsibilities and stripes and ripples may appear on the tablet screen. This most often shows up in games when streaking and other artifacts begin to appear. On the Internet you can find several ways to improve the cooling of a Chinese tablet at home. If the device is manufactured by a well-known company, then it is best to take it to a service center.

Stripes and ripples appeared on the tablet after falling into water

If the device comes into contact with water, first of all it must be thoroughly dried, for which it is best to first disassemble it. If this method does not help restore functionality and the stripes and ripples from the tablet screen do not disappear, you will have to visit a service center. There are qualified craftsmen who can determine what exactly was damaged during bathing.

What to do if stripes appear on the screen after the phone falls. Video guide from PC4USER.

If stripes or ripples appear on the tablet after an impact or fall, there is a possibility that the cable connecting the device’s motherboard and display has popped out of the connector. At the same time, the tablet itself is visually intact, there are no permanent black spots on the display or cracks. In this case, the device user can try to fix the problem themselves. To do this, you will need to carefully disassemble the tablet and insert the cable back into the socket on the system board.

In the event that you know that the tablet 100% did not fall, but the stripes still appeared on their own, you will probably have to take the tablet to a service center to replace the cable. Unfortunately, it tends to “wear out” over time.

Mechanical damage to the matrix

If ripples, stripes or spots on the display appear due to shocks, falls, and other physical influences, this may indicate damage to the matrix. This type of failure can be distinguished from the previous one by the presence of a crack under the touchscreen, or by the presence of dark spots of various sizes, which retain their constant position when the display is turned on. You can do independent repairs only if you have experience in replacing the display, and also have a new display in stock. Otherwise, you need to take the device to a workshop. Replacement costs vary depending on the tablet model and display size.

Video driver failure

Sometimes the reason for the inappropriate behavior of the image on the display may be caused by a software glitch. How to distinguish problems in the system from problems with the loop? If the tablet has not been subjected to mechanical stress, but the image changes color on its own, or duplication or overlaying of images occurs, try resetting the tablet to factory settings. If this does not work, you can try to reflash the tablet. And only if these manipulations do not solve the problem can we assume that the cable is the culprit of the malfunction.

Cooling problem

Some budget tablets made in China may have problems with overheating and lack of cooling. The tablet may work quite normally, but after heavy load (for example, after playing games), it may freeze and streaks will appear on the display. After some time, the stripes disappear on their own and the tablet works again. Such symptoms clearly indicate poor-quality cooling, or even its absence. At home, you can organize a cooling system only if you have knowledge and skills in this area. In other words, may the service center help us.

Tablet screen flickering

When a tablet screen flickers, it is quite difficult to determine the cause. Let's look at how this happens. The first option is software, that is, you just need to update the firmware. It’s unlikely, although users often fixed the problem by adjusting the power application, sometimes the reason was in a specific energy saving profile.

The second option is hardware. Here it all again comes down to poor contact between the display cable and its connector. More precisely, this is something that can be checked. If the loop does not help, then you only need a specialist to diagnose and, as a rule, you will not achieve anything.

The fact is that the tablet screen also flickers in cases low-quality capacitors. They must be made of silicon, but Chinese manufacturers often try to save money on this. Sometimes a group of capacitors is not completely soldered. You can solder them personally, although this happens extremely rarely.

A frightening situation - stripes appeared on the phone screen. But when using a mobile phone, no one is immune from this. And, it doesn’t matter how long you use this phone, the problem may arise immediately after purchase or after a few years. Let's take a closer look at why stripes may appear on your phone screen, and what to do about it.

Reasons why stripes appear on the screen

The appearance of streaks can be due to a number of reasons that are inevitable when using a cell phone:

  • falls from a great height, impacts, pressure on the screen;
  • moisture ingress;
  • software failure;
  • viruses that can be downloaded and installed along with unverified applications;
  • overheating when charging;
  • manufacturing defects.

When using cheaply assembled phone models, any fall, shake, or blow can cause contact breakage, damage to the microcircuits and, as a result, the appearance of stripes on the screen.

The stripes themselves can also tell you about the cause of the problem. If a black line appears on the screen after a fall, this indicates that the screen itself is damaged and needs to be replaced. If there is moisture or mechanical damage, multi-colored or white stripes may appear. Blue, yellow, green stripes indicate a possible software failure. The appearance of a red stripe indicates a manufacturing defect in the display; in this situation, it will most likely need to be replaced. Damage to the controller is indicated by the appearance of colored ripples on the screen.

What to do if stripes appear on the screen?

If, by all indications, the appearance of stripes on the screen is due to a software glitch, then at home you can reset to factory settings. If this does not help, then it is better to contact a service center, where specialists will reflash the phone and clean it of viruses.

In case of mechanical damage or moisture on the phone, it is better to immediately take the device to a repair shop, since repairing it yourself can aggravate the situation and make the repair more expensive.

The appearance of stripes on the screen is a fairly common occurrence. At the same time, the phone fully retains its functionality and the presence of stripes causes inconvenience when watching videos, reading, etc. #streaks appeared on the phone screen #stripe on the screen #red stripe #multi-colored stripes #blue stripe #white stripe #green stripe #yellow stripe #black stripe #why are there stripes on the phone screen #after a fall

You could leave everything as is and continue to use the phone, but if this breakdown is related to damage to the phone, then over time the problem may worsen and more expensive repairs will be required. Therefore, if stripes appear on the screen, if you cannot cope with this at home, it is better to contact a specialist at a service center. In the service center, after diagnostics, the problem can be solved quickly and at a low cost.

A. What to do and how to treat?

Many users encounter a problem when phone or The Android tablet starts acting up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.

For example, the device has problems with defects of one kind or another in the image, color rendition, etc.. The reason for this may be:

1st: Software glitch- i.e. the problem is a software glitch

2nd: Hardware failure- i.e. the problem is in the hardware (i.e., replacement or restoration of spare parts for the gadget is required)

However, do not rush to get upset - in 90% of cases there are problems operation of the system for adjusting color correction, detailing and other functions of the display smartphone a or Android tablet is to blame software glitch which you can easily fix on your own.

Fixing a software glitch:

Method 1. Quite simple - go to "settings", find there "backup and reset", in which you choose full reset settings with deletion of all data. Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if even after this the problem is not resolved, see Method 2.

Method 2.

Based on solving problems with communication and network reception phone number and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a lot of them, however, the fewer functions an application contains, the more effective it is, as a rule. The best tool to monitor system functions, corrects and corrects all possible settings and synchronization errors is an easy-to-use, free utility for Android devices. You can download the application from Google Play and see its additional options in the description. After installing the application, all that remains is to launch it. Further, in principle, nothing more is required from you. The application will take full control of the device's functions. (By the way, among other things, the gadget will begin to charge 20% faster, and its performance will also increase significantly, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system runs at 50% faster.)
Method 3.

Changing the device software, or as it is also called "re firmware ". This method, as a rule, requires certain skills and can be solved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.

If none of the methods brings results, unfortunately, you will have to contact the Service Center for repairing your tablet a or smartphone a.

Stripes or dots appear on the screen of your Android smartphone or tablet. The display of a smartphone or tablet ripples, flickers, and blurs the image. What to do and how to treat?

Lines on the phone screen are a very common problem. The main trouble is that such a malfunction can appear at any time: on the day of purchase or after several years of use.

However, despite the frequent occurrence of the problem, there are still device owners who do not know how to solve it.

What does the defect look like?

The main thing to remember is that the display does not lose functionality after a malfunction is detected. But this is not a reason to abandon the device in this state, because only its owner suffers from the incorrect functioning of the smartphone. If stripes appear on the phone screen, the image quality drops, so you will have to exclude reading and watching movies (few people like to “break their eyes”). That is, there will no longer be any point in having such a device.

The defect manifests itself as distortion of the content on the display. It ripples and runs in stripes (horizontal or vertical) of different colors: from black to iridescent tints.

Classification

Using this section, you can indirectly find out the cause of the breakdown, but it will be quite inaccurate. However, it's worth a try.

  • For example, colored and white stripes on a phone screen are often a sign of mechanical damage to some component of the display or a loose cable fit into the groove.
  • Black lines indicate the need to replace this part of the smartphone.
  • Colored ripples indicate a problem with the controller.

However, without opening the case, such “diagnosis” cannot be confirmed, so either your own hands or service centers can help.

How does the defect manifest itself?

This section is also important, as it will make it clear which part of the device (hardware or software) the fault relates to. Everything is quite simple here:

  • If stripes appear on the phone screen only when you launch a specific application or make any changes to the settings and files of the device, then the problem is a failure of the operating system.
  • When lines appear on the display after mechanical intervention, damage, or when touching the touchscreen, we can safely talk about problems in the hardware itself.

After determining the type of malfunction, you should move on to methods for solving it.

Line on the phone screen: what to do?

If the problem is caused by mechanical damage, then there are two ways: take the gadget to a service center or disassemble it yourself. In the latter case, you should look for a master class in video format that will show you how to open the case and get to the display. Next, you will need to carefully examine this part of the gadget to understand the extent of the damage.

If the problem is only that the cable does not fit tightly into the groove, then it is quite simple to correct it, and the stripes on the phone screen will disappear. But if it or the controller (chip) is damaged, there is nothing left but a complete replacement of components.


In the event of a software failure, the situation is usually corrected by a hard reset (resetting the settings, during which all personal data is deleted; it is recommended to save important files before performing it) or cleaning smartphones from viruses. Although the first method is more reliable, since many OS protection programs do not see the pest.

Multi-colored stripes on your phone screen are not a death sentence

Even the most reliable equipment fails from time to time. Sometimes mysterious defects may appear on the display of a smartphone or tablet. If you notice that a line has appeared on your phone screen, what should you do?

This is a fairly common breakdown, so you should know what causes the defect and how to fix it. We list the causes of problems according to the frequency of their occurrence:

  1. Loop contact failure.
  2. Crack in the display matrix.
  3. Software glitch.
  4. Excessive load on the system.
  5. Getting wet.

And having repaired possible damage yourself or with the help of a service center, you can continue to use your smartphone to communicate with friends and work colleagues and use health applications on your gadget.

The display cable has come loose from the connection socket

The most likely reason for stripes appearing on the phone screen is a loss of contact with the cable due to an impact or fall, while there may be no visible damage on the display or case - cracks, stains or discolored areas. Also, the cable may come off due to sudden shocks and shaking.

If the contact goes away, you should contact the service center to troubleshoot the problem. But if you consider yourself an advanced user and think that you can restore the functionality yourself, then you just need to press the cable so that it fits tightly into the socket connector. However, you must be careful when disassembling the smartphone - you should not touch adjacent connections or “disturb” other miniature and sensitive elements.

Please note that opening the smartphone yourself will void the warranty!

In very rare cases, damage occurs within the cable itself. Then it is necessary to completely replace the part. Its cost is low, as are the prices for the work of a specialist to install it.

Crack in the screen matrix

This defect often occurs when falling. Visible white, black or red stripes on the phone screen occur when the matrix and glass are damaged. In this case, cracks appear that can be identified by touch.

In this case, there is only one repair method - replacing the screen. Its price, unfortunately, is quite high; it consists of the cost of spare parts and specialist work and is determined by the service center.

Software glitch

In some cases, ripples or stripes on the phone screen occur due to software failures. Sometimes unnatural colored spots appear and images overlap. Such defects can be caused by a virus, a bug in recently installed software, or an incorrect firmware update.

The fix method is to reinstall the software or reset to factory settings. A more radical way is to restore the settings at a service center. Firmware for some can be found on the pages of our website.

Periodic freezes with image distortion

If defects appear intermittently and are accompanied by program freezes, they are associated with overheating of the processor or video chip. The game pauses and appears simultaneously on the phone screen.

Today on various forums you can find several ways to independently correct these defects. But if you are the owner of a smartphone with a warranty, we recommend that you contact an authorized service center that services devices from the best manufacturers.

Defects associated with smartphones falling into water

If the reason for the appearance of streaks or streaks is obvious and is associated with the device being exposed to rain, a shower or a puddle, repairs should begin by turning it off. Then remove the battery, disassemble the case and dry all the parts.

If after drying and turning on the stripes or ripples do not disappear, you will have to contact a service center.

If an android with appears on the screen, this means that an unsuccessful experiment was carried out with the device’s software. This may have happened due to the installation of an unlicensed program or after switching from original firmware to custom firmware.

Hard reset

This action is carried out in the device’s engineering menu and allows you to return the smartphone or tablet to its original settings, which is very useful when the android lies with an exclamation mark. A special engineering menu is called up by pressing certain buttons, but there are some difficulties here. Models from different manufacturers have different key combinations. There is a certain sequence in calling the engineering menu.

The device must be turned off. It is best if the battery is fully charged. For most gadgets, the following combinations of buttons to open the menu are suitable:

  1. The Volume Down key (or Volume Up key) is pressed and held together with the Power button.
  2. Both sound control keys are pressed and held, and then the power key is pressed.
  3. 3 buttons are held simultaneously: main screen, volume up and power.
  4. The Home key is pressed together with the sound control key down, then the Power key is pressed. You must wait until the manufacturer's splash screen appears and release the Power button. After the robot image appears on the screen, you can release everything and wait for the engineering menu to appear.
  5. Press and hold the power button for 2 seconds, then hold down the sound control keys and the power button and hold until a special menu appears.

After this, the gadget will either restart and return to factory settings on its own, or an engineering menu will appear. For your information, in this mode the touch screen does not work, all menu navigation is carried out using the sound control keys, and the selection button is the power key or the Home button. You must select “Wipe data/Factory reset”.

Several lines and a question will appear on the display (“Delete all data from your device?”). You must agree, after which the device’s memory will be cleared.

Reset on different devices

On smartphones and tablets manufactured by Samsung, the engineering menu is entered by pressing 3 buttons simultaneously: the gadget's main screen key, the volume up key and the power button. Resetting to the original settings is done using the Wipe data/Factory reset item and then rebooting.

HTC devices, when Android with a red exclamation mark appears on the display, can be brought back to life by pressing and holding the power and sound control buttons. When Warning appears on the display, you can release everything and press the volume up key. On some models, hold down the volume button and press the power key until an android robot appears on the screen. After it appears, you can release the buttons and press the volume down key again. A menu will appear in which you need to select “Restore original settings”.


On Acer smartphones, settings are reset by pressing and holding the volume up key and the power button. A menu will appear on the screen where you need to select Recovery Mode and press the volume down key. An android with an exclamation mark will appear. Now you need to press the power button. A menu will appear where you need to select Wipe data/Factory reset.

And on the tablets of this company, you need to move the screen lock lever to the left position, press and hold the power button and sound control keys. When the tablet starts to vibrate, you need to change the position of the screen lock lever several times until the words Erasing Userdata and Erasing Cache appear on the display. From this moment, the removal of settings will begin.

To return to factory settings, Asus devices must be switched to the engineering menu by pressing the volume down key and holding down the power button for 3 seconds.

After the time has passed, you can release the power button and hold the volume down key until a special menu appears. There you need to select Enter recovery mode, then Wipe data/Factory reset.

Device firmware

If a hard reset does not help, a complete software replacement is required. But there is a formality here: the firmware will only help if the “USB Debugging” function has been enabled in the device settings. This method is quite risky and the slightest violation of the instructions can lead to damage to the device.

Here it’s worth thinking about: should you try to restore the device yourself or trust the professionals? But if you decide to flash the gadget yourself, you should carefully study all the available information on this issue. Models from different manufacturers have significant differences and features regarding software changes.

In general, the process of replacing software looks like this: download the file with the firmware, study installation information, read reviews about this firmware version. Next, the file should be unpacked into the root directory of drive C and, if necessary, install drivers for the gadget. After this, the device must be turned off and using a key combination (usually a combination of the power button and volume up) switched to firmware mode. Then you should connect the device via cable to the computer and follow further instructions of the program. At the end of the process, you must perform a hard reset using the engineering menu.

The article covers a current topic - Tablet display not working, root causes and troubleshooting. Here we will look at the most common causes and options for fixing the problem yourself. The proposed circuits can be used to repair both resistive and capacitive types of sensor.

Tablet display malfunction due to dust and water.

Quite often, dust particles end up between the glass and the touch film. As a result, when touching the surface, the user observes an inadequate sensor response. In this case, you can wash off the dust with ordinary distilled water. The surface can also be cleaned with a lint-free cloth or soft brush. You need to act carefully so as not to damage the screen.

If the cause of the malfunction is water that got into the tablet, then you should disassemble the device. To work, you may need screwdrivers, special “openers” and a hair dryer. First of all, you need to get to the cable that comes from the sensor. The cable must be removed from the connector and thoroughly dried with a hairdryer. It is important to work carefully and try not to damage the cable.

Do-it-yourself tablet display calibration.

Sometimes when purchasing a tablet, users find that the device does not respond correctly to every touch. In this case, the problem may be due to incorrect settings. Calibration is quite easy - you just need to find the “Display” section in the options. If you wish, you can contact a specialist who will perform the procedure for a few minutes.

The tablet is heating up - what to do?

In this case, many users mistakenly assume that they may need to tablet repair. If the device heats up while charging, the problem can be solved in just a couple of minutes. It is recommended to purchase another, more suitable charger so that the voltage remains the same and the amperage is less. Then the tablet will not heat up so much.

The tablet display does not work - the tablet has a white screen, what should I do?

The situation is that the tablet has a white screen and the device does not react in any way to the Hard-Reset input. There is a fairly high probability that the internal memory has become damaged. As a rule, flash memory is practically no different from a removable micro card. It’s just located on the tablet’s motherboard, under the technical tape. So, we solve the problem with the white screen:

  • The tablet needs to be disassembled.
  • Next, you need to remove the flash memory and format it on your computer.
  • A caveat: it is strongly recommended not to change the partition name; formatting must be done in FAT32.
  • If necessary, the memory can be a similar part - you should choose exactly the same option.
  • At the final stage it remains tablet firmware- write down the OS.
  • It is recommended to carry out the same procedure with external memory.

Sometimes the internal memory may simply not record the firmware. In this case, you should try using the original version. As a result, you can simply turn on the tablet and the installation will start. Instructions about how to flash a tablet can be found on our website.

Stripes appear on the tablet screen - what to do?

As a rule, stripes on the tablet screen appear due to overheating of some elements of the device. The fact is that on budget models the Wi-Fi module, voltage connector or chip may be located too close to the matrix. As a result, these elements overheat, and the user sees ugly stripes on the tablet screen that distort the image.

There are two options for solving the problem - replacing the matrix and isolating overheating parts, or installing some kind of heat sink. In any case, such work can only be carried out by specialists. With minimal work, you will have to put a copper plate on thermal paste. Therefore, it is recommended to either buy a new tablet or use the device in restricted mode.

Restriction mode means refusing to watch quality movies online. In this case, it is advisable to rid the tablet of a thick case to improve ventilation. As for games, heavy or large games can only be played with “rest” breaks, as the tablet must cool down. One way or another, the user will have to think about replacing the device with a better option.
