In order to reduce your losses, it is recommended that you turn off your mobile phone and bring the relevant proof of purchase to a nearby Huawei customer service center for repair. You can use the Huawei official website to find the address of a Huawei Customer Service Center near you.

Precautions after water and liquid ingress in the mobile phone:

1.Do not move or shake your phone frequently after the liquid is ingested to avoid moisture spreading inside the phone.

2.Do not blow with a hair dryer or bake at high temperatures (including microwave heating) after liquid infusion, so as to avoid liquid being blown into the phone and damage the phone by high temperatures.

3.Mobile phones are made of delicate electronic components, and there is a potential risk after liquid ingress, so please keep your phone turned off.

4.If you don't have a backup of your data, there may be a risk of data loss during repairs. After you go to the Huawei Customer Service Center, you can consult with a staff member to help you evaluate whether you can back up your data.

This can only be sent to a mobile phone store for repair! Speaking of the water in the mobile phone, don't turn it on immediately, put the mobile phone in the meter, take it out after a while, try it, but your mobile phone is falling into the urine, it's very difficult!

It should be that the motherboard is broken, so I can only replace the motherboard! In this case, it should be turned off as soon as possible, then turned on to dry vigorously with a hair dryer and then thrown inside the rice.

Send it to the mobile phone store, I have no hope of rescuing.

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.
