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.
With seemingly careful handling. Let's look at the options why stripes appeared on the tablet screen.
The most common problem is the cable wearing out or falling out of its socket. This can happen from any blow. Even if, in your opinion, the fall was trivial, and there is no visible damage, the cable may jump out from the shake, so you will need to push it into the socket, otherwise you will not restore functionality.
Just be extremely careful, if you touch any other element, you risk being left without a working device, because with its miniature size, it contains dozens of the same small spare parts that will not be easy to repair on your own.
If the cable stubbornly refuses to transmit data as expected, it means that the spare part is worn out. In such circumstances, you can no longer do without visiting a service center. But don't worry, replacing a cable has never been an expensive procedure. This causes the tablet screen to show stripes.
In second place in the frequency of cases is damage to the matrix or display. Again, if you drop the device, there may be physical damage to the protective glass. This kind of damage will be visible immediately after the fall, as cracks, chips will appear, and stains or ripples and stripes will immediately appear on the screen. If an accident has occurred, you will not be able to change or fix anything on your own, except perhaps be more careful next time. In the meantime, you are waiting for a trip to the service center to replace the matrix or display. The price of the repair will directly depend on the model of your tablet and the size of its screen, but in any case, you won’t be able to get by with an inexpensive repair. If the tablet screen has white stripes, you should take the device to a specialist for diagnostics. Apple tablets and phones suffer the least from this. And buying a tablet from this manufacturer is as easy as buying an iPhone cable. After which it can be used with some advantages.
Much less often, a software failure occurs and then you can observe strange color distortion, ripples, thin gray or black stripes on the tablet when you turn on the device, overlapping of several images on top of each other, and other inappropriate behavior of the device. In this situation, try resetting all settings to return the tablet to factory settings or do a full reset, which is a much more radical method.
Do not forget that if there is insufficient cooling, tablets tend to overheat and show colored or green stripes. In this case, the video chip may not cope with its responsibilities and ripples and stripes will also appear on the screen, the tablet itself will begin to work with stutters, and during this the image will look scary. This usually happens when playing games that require certain conditions from the system of your device. While playing this type of game, if the screen gets overheated, these image defects may appear on the screen. If your tablet is from , you can find options for cooling it at home on the Internet. If your device is manufactured by a well-known company, take it to a service center, where they will help you without harming the equipment. The problem will not be solved on its own.
Be careful with equipment, never forget that the proximity of all kinds of liquids is dangerous for any electronics. If for some reason your tablet ends up in water, be sure to carefully and thoroughly dry the device. You may even have to take it apart to dry it better. If suddenly this did not help you restore the operation of the device, and the image on the screen is still covered with ripples and resembles a chessboard, you are on your way back to the service center, where qualified specialists will determine what exactly gave up the ghost during water procedures. Stripes on a tablet screen are most often the result of careless handling of the device.
Remember that careful handling of technology will save your nerves, money, and possibly even your life in particularly advanced cases. And if you do not understand the insides of your device, it is better to use the services of professionals so as not to damage the device even more.

Every day, users of Android devices come to service centers complaining that their phone screen is flickering. This problem is far from new and has a number of reasons for its occurrence. Let's sort things out in order.
Despite the rapid development of mobile technologies, they have not yet made it possible to create a device that can withstand strong shocks or software failures. For each gadget, the cause of a display malfunction can be very different, so before drawing final conclusions, let’s look at each of them in more detail.
Screen damage
The first flickering and “jumping” of the picture on the phone can appear after a serious fall or contact of the device with water. This may damage:
- Screen.
- Microcircuit (video controller).
- Cables connecting elements into a single system.
If in the first case, any specialist in the field of mobile technologies can deal with the problem with a minimum number of tools, then the second and third require a meticulous approach and the presence of special equipment.
Video controller
The so-called graphics subsystem, consisting of memory, processor and “piping,” is responsible for outputting images. When one of the elements on the electronic board burns out, problems begin - the appearance of ripples, “artifacts”, interference, blinking, flickering, stripes and other unpleasant symptoms on the smartphone screen. In this case, it is not recommended to act on your own; there is a possibility of damaging the video controller even more.
Software failure
Most users do not even suspect that the display begins to flicker due to a conflict in the operation of several applications, the presence of a virus in the system, excessive system contamination, or hidden software glitches. The user is able to independently clean the smartphone, roll it back to factory settings and install anti-virus programs from the official Google Play store.
However, if these manipulations turn out to be useless, reflash the device. It is better not to do something like this with your own hands, without prior practice, otherwise the gadget will be completely disabled. The right way out of this situation is to contact a service center.
Battery problems
As a rule, everyone begins to think that the malfunction was caused by damage to the device’s system, completely rejecting the simplest options. Flickering of the display can be caused by a weak battery. This happens due to the loss of its power when the battery is used for several years without replacement.
Testing this option in practice is quite simple. Connect the charger to the phone and look at the display, if you manage to get rid of flickering, then it’s all about power. We recommend taking another battery and performing a similar test. If this is really it, you should go to a specialized store and change the battery. At the same time, special attention should be paid to its originality; a Chinese fake can fail a month after purchase. In some cases, it can even cause harm.
However, one interesting catch may be the non-removable battery on your phone model. In this case, it is better not to take risks and entrust the solution to the problem to specialists.
Secret codes for testing
There are several more ways to find a possible problem; to do this, refer to the service codes, which are suitable for all smartphones running Android. The codes can help in setting up the system and identifying the reasons when the smartphone screen begins to tremble (twitch) or shimmer with all the colors of the rainbow.
*#*#4636#*#* - allows you to view basic information about the phone, battery, user statistics.
*#*#7780#*#* - resets settings, removes only existing applications.
*2767*3855# - a complete reset of settings occurs, with reinstallation of the existing firmware.
*#*#0*#*#* - quick test of any LCD display.

This includes not only mechanical damage and partial malfunction of the software, but also problems with the battery, which over time could lose its power and cause unpleasant consequences in the form of flickering or flickering of the display.
The only correct decision in this case is to visit the nearest service center, where, using special equipment, they will conduct a full diagnosis of the device and identify the main cause of the breakdown.
Of course, you can repair your phone yourself, however, you should take into account that without the proper knowledge and practice, your smartphone can completely fail, without the possibility of further restoration.
