If the HUAWEI Mate30 suddenly has a black screen, it may be caused by a virus problem, and the phone will be blacked due to a Trojan virus attack, or it may be due to an abnormality when running some specific applications, which will cause the system to be incompatible and cause the phone to have a black screen. Or when the phone memory is insufficient, it will affect the running speed of the system, resulting in a sudden black screen.

See if it's a freeze.

It depends on what is causing the black screen. Different problems have different solutions, and we can't generalize.

I'm a mobile phone repair master, let me talk about it.

The Huawei phone suddenly has a black screen and does not turn on. There are two scenarios:

First, there is a sound and a response, most of which are burned by the screen, or the chip that controls the display.

Clause. Second, there is no reaction, and some people still have fever.

Most of the motherboard is charged and burned, the current is too large, and the motherboard has a power manager, similar to the electric switch at home, if the current is too large.

In order to avoid further burning out other parts of the motherboard, it will go into trip mode, which means that the power manager is sacrificed first.

If it is further charged, it will burn other chips as well. So never charge.

There is also a part caused by water ingression, which may have burned other chips.

Under normal circumstances, you can change the power chip, and the conventional chip is only 34 hundred yuan. Far cheaper than changing a motherboard for 34 thousand.

Don't listen to those masters who don't understand chip repair, and you want to replace the entire motherboard or something.

It's like if the toilet in your house is broken, the knowledgeable ones will let you change the toilet, and the ignorant ones will let you change the house.

The above figure is the chip structure diagram for reference.

I have been doing mobile phone repair, and I know more about these.
