Believe everyone has experience with cell phones falling on the ground, either broken or black screens, and of course, if you and yourself push harder to crush them on the ground and crush them, if that's just black screens, you know how to define how you can fix your cell phones? Now let us teach you how to judge some simple screen failures, some of which may be just a loose line that leads to black screens, without spending money。
What if the screen breaks
In fact, the problems on the screen are relatively easy to judge, and can be divided into two types, in the words of @geekbar's specialist maintenance expert: one can solve the problem of disassembly grade, the other the problem of chip grade, which can be solved by replacing parts such as screens, cameras or lined lines with machines, and the other the need to replace chips on the main plate with complex tools and crafts such as electric iron。
Of course, here we can only teach you how to solve the problem of decoupling screens, for example, by taking the relatively hot iphone 5s, which are divided into layers, from top to bottom, with glass cover, glue, luminous tablets, displaying liquid crystals + tentacles, backlight modules, if the glass cover on the screen is broken, replace the corresponding glass cover。
In the case of a screen leachate, it is sufficient to replace the backlight module on the last layer of the screen, because of the relative thinness of the glue between the backlight module and the display of the liquid crystal, which cannot be compared to the glue between the glass covers and the display of the liquid crystal, which does not function as a visual effect such as to adjust the colour of the display and does not need to cover all the glue, so liquids can enter the layer。
As for the problem with displaying liquid crystals, the only way to change the screen is to change the screen and change the screen。
The screen is not broken, it's just black, and the problem is relatively complicated。
Turning briefly to the black screen problem, it is difficult for even professional masters to identify the problem in the first place, because it is highly probable that the screen is broken, and it is probably because of the chip problem, and in this case it is recommended that you be sent to a professional maintenance facility for testing, and if it is a formal institution, simple testing is free, and if they say they can only do it behind your back, then let's move。
What would cause a chip-level failure
Chip-level failures can be described as relatively serious, with the change of the master plate or even the entire cell phone if the chip is lighter or heavier, but the problem is not due to particularly high probability, such as water entry, heavy fall or the previous vocabulary door, but it is difficult to cause a chip-level failure if it is just a normal fall from the desktop。
Finally, professional maintenance staff often use exclusionary methods when dealing with problems such as black screens, such as unwinding machines to see if they are loose, then testing the screens for good or bad, and then testing the master plate of machines for bad or bad. In any event, in the case of ordinary consumers, if you fall blackscreens, you may wish to try to unwind it yourself, if you do not consider finding a professional maintenance agency for systematic repair。
