Vertical stripes on a smartphone. Stripes on the screen (phone) of the tablet after a fall (what to do?)
Stripes and ripples appear on the screen of a tablet or phone - what should I do? There are several reasons why stripes may appear on your device's display. on the example of repairing N8000 stripes in the image (artifacts)
channel Ivan Voronin channel - https://goo.gl/0tob3D In some cases, the problem can be eliminated on your own, in others it will only help service center... The most important thing is to find the root cause, the source of the ripples and stripes.
Out of order, or the train has come off
If streaks or ripples appear on the tablet after being hit or dropped, chances are the ribbon connecting the device's system board 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 user of the device can try to fix the problem himself. To do this, you need to carefully disassemble the tablet, and insert the ribbon cable back into the socket on the system board.
In the event that you know that the tablet did not fall 100%, but the stripes still appeared on their own, you may have to carry the tablet to the service to replace the cable. Unfortunately, it tends to "wear out" over time.
Mechanical damage to the matrix
If ripples, streaks or spots appear on the display due to impacts, drops, or other physical impact, this may indicate damage to the matrix. This type of breakage 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 on. Self-repair can only be done if you have experience in replacing the display, and a new display is available. Otherwise, carry the device to the workshop. Replacement cost varies depending on tablet model and display size.
Video driver failure
Sometimes the reason inappropriate behavior the display may be caused by a software glitch. How do I distinguish between system failures and loopback problems? If the tablet has not been subjected to mechanical stress, but the image changes in color by itself, or duplication occurs, the image is superimposed on one another, try resetting the tablet to factory settings. If this does not work, you can try reflashing the tablet. And only if these manipulations did not solve the problem, it can be assumed that the loop is the culprit.
Cooling problem
With some budget tablets made in China, there may be problems with overheating and lack of cooling. The tablet may work quite well, but after a heavy load (for example, after playing games), it may freeze, and stripes appear on the display. After a while, the stripes disappear by themselves 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 the knowledge and skills in this area. In other words, may the service center help us.
Flickering tablet screen
When tablet screen flickering occurs, it can be difficult to determine the cause. Let's take a look at how this happens. The first option is software, that is, you just need to update the firmware. It is unlikely, although often users fixed the problem precisely by setting the application for power, sometimes the reason was in a specific power saving profile.

The second option is hardware. Here everything again comes down to poor quality contact between the display cable and its connector. More precisely, this is something that can be checked. If the loop did not help, then only a specialist is needed for diagnostics and, as a rule, you will not achieve anything.
The fact is that the tablet screen flickers even in cases of low-quality capacitors. They should be silicon, but often Chinese manufacturers are trying to save money on this. Sometimes a group of capacitors is not completely soldered. You can solder them personally, although this happens extremely rarely.
