Why does Huawei tablet sometimes have a black screen

The black screen of the mobile phone is one of the faults that are often encountered in the repair of the mobile phone, and the black screen can be divided into two types:

One is a black screen in use, and the other is a black screen in standby.

Here are some basic causes and solutions for black screens:

Most of the black screens in use are caused by their own third-party software, and this situation rarely occurs with the machine. It can also be subdivided into two kinds: one is that there is a problem with the software itself, the software itself is unstable, or it does not match the mobile phone system, etc., this is easy to solve, just uninstall it; The second is the conflict between the software and the software, which is a little more troublesome to solve, and requires a software to install and uninstall the software in the experiment.

If you find it, uninstall it, and the problem will basically be solved.

Black screen in standby,Let's talk about the standby principle first,Straight board machine because most of them have a power-saving circuit design:The mobile phone will automatically turn off the screen if it can't detect the key trigger signal for a long time,That is, standby,When you need to use the phone, a button will activate the power-saving circuit,Then the screen lights up。

The reason for the black screen is often reflected by the delay of the screen triggering circuit. That is to say, the mobile phone system has issued a command to light up the screen, but because the circuit is delayed, it is not sent successfully, and the screen is not lit successfully, but the mobile phone system thinks it has been lit, so it causes a black screen.

Hope it helps!
