The phone screen is black after entering the water, do not rush to turn it on, you should remove the SIM card first, and then disassemble the phone to clean the motherboard and various interfaces inside the phone.

If the screen is still black after treatment, the problem can usually be fixed by repairing the damaged circuit and replacing the screen.

The solution to the black screen caused by water ingress on the phone.

1. Clean up the external liquid in time and take out the card tray.

Don't rush to press the power button to see the condition of the mobile phone after the mobile phone enters the water, no matter what kind of liquid it is, wrap the body with a paper towel first, and clean up the liquid in time, especially the earpiece, speaker, phone delivery hole, charging interface and buttons. Then remove the card tray and shake the liquid out of the card tray with force in the direction of the card slot.

2. Within the scope of ability, disassemble the mobile phone according to the body structure.

Most of the current smart phones are all-in-one machines, which can be roughly divided into three types in terms of disassembly methods:

1) The screen and bracket are stuck on the metal back cover and fixed by screws. You can unscrew the screws first, and then use the suction cup with the disassembly stick to disassemble the phone, such as the iphone7 series.

2) The motherboard is fixed on the middle frame and protected by an integrated back cover. This is one of the more common constructions, usually with screws at the bottom of the metal back cover. In contrast, it will be easier to remove the phone with a plastic back cover, such as some low-end phones.

3) The motherboard is fixed on the middle frame and protected by the bracket and the back cover. For mobile phones with this structure, you need to remove the plastic or glass back cover first, and unscrew the screws that fix the bracket before you can see the motherboard, such as Huawei nova5 series.

During the disassembly process, it is necessary to identify the position of the key cable and fingerprint cable to prevent damage. In addition, do not use metal equipment, so as not to cause damage to the battery.

3. Remove the large and small motherboards and clean the liquid and oxides on the motherboard.

When removing the motherboard, buckle the battery cable first, and then operate on the other connectors. It should be noted that when removing the cables, do not use brute force to avoid damaging the interface.

After removing the motherboard, you can soak the motherboard in the washing water, if conditions permit, you can use an ultrasonic cleaner, or directly use a soft brush to clean the oxidized area of the motherboard, focusing on cleaning the screen cable base, small board cable base and power supply peripherals.

After cleaning, remove the motherboard and use a household hair dryer to blow the motherboard and middle frame at medium temperature (40 degrees Celsius) for about 10 minutes.

4. Install the motherboard and reset all interfaces.

After the motherboard and battery temperature return to normal temperature, put the motherboard back on, connect the screen and battery, and try to turn it on.

If it can be turned on, and all functions are normal, the repair can be completed. If your phone is ringing but the screen doesn't appear, you can continue with the following steps.

5. Check the integrity of the screen cable and the surrounding circuit.

The normal tin dots of the cable base and peripheral components are silver, and shiny, and the position corroded by the liquid is black, if the corner is missing or damaged, the screen will not be displayed, which is basically a backlight problem.

For this kind of problem, it is beyond the scope of personal repair, and in order to avoid greater losses, it is recommended to hand over the phone to a professional for repair.

The solution to the black screen of the mobile phone is as follows:

1.If the phone falls into clean water, wipe the phone with anhydrous alcohol, use a hair dryer, and dry it. If you continue to charge the phone without drying it, it will short-circuit the internal components of the mobile phone and burn out the components.

This will further expand the fault and make maintenance more difficult. 2.If the mobile phone falls into the sewage, there are many acid and alkali compounds in the sewage, which will cause corrosion to the mobile phone.

When disposing of it, the corrosive material that can be seen is cleaned first. Use a brush to brush off the impurities attached to the pins of the components. Then, use an alcohol cotton ball to clean the circuit board.

3.Rash opening will cause the display screen and other parts to burn out, which is a replacement that needs to be repaired. Extended Materials.

Phone Black Screen Reason:

1.Under normal circumstances, when the mobile phone stores too many things, many friends can feel that the mobile phone is running too slowly, and when their mobile phone is occupied by 80% of the memory that can be driven, it may crash.

2.This is the loosening of the contact of the mobile phone screen, which is not a big problem, but it can directly cause the black screen of the mobile phone, and it is difficult to find that it has to go through a lot of tests to find, which is generally caused by the mobile phone being bumped.

3.It is common for many mobile phones to have a black screen after using it for a long time, the main reason is that the effective use time of the mobile phone battery is 1 year, or it is three years but there is a problem in one year, and excessive use leads to the aging of the mobile phone's battery and insufficient voltage.

4.There are a lot of applications for smartphones nowadays, but there are some software that are inherently conflicting, which can also lead to a black screen, so the black screen after installing a lot of software is basically this reason.

5.Many people are keen to flash the machine and use a better system, in fact, some system mobile phones are not very supportive, and some are not complete, resulting in a black screen when using it in the future.

If the water ingress is not shut down in time, there is basically not much maintenance value, so buy a new one.

I can only repair the head office, and I can't solve this kind of problem by myself.

Huawei mobile phone can't be turned on after falling into the water, black screen, it can be repaired, go to the mobile phone repair shop to check if it is burned out, the motherboard is still the screen, you can replace the corresponding parts, and the repair will not waste a long time. After replacing the new parts, it can be operated normally.

1. After the mobile phone enters the water, please keep away from the water source and turn off the phone immediately, if the mobile phone has been automatically turned off, please do not try to turn it on. 2. Please wipe the water stains on the surface of the mobile phone immediately, and place the mobile phone in a strong water-absorbing environment (such as activated carbon, rice, moisture-proof agent) for more than 48 hours, and confirm that the mobile phone is dry before trying to turn on the operation. 3. If some functions are missing after the mobile phone is turned on, such as the keyboard light is not lit, the screen touch is not working, etc., it means that the hardware is faulty, please contact customer service immediately or go to the service outlet for maintenance with the purchase invoice.

If your mobile phone gets into liquids such as coffee, cola, milk, seawater, etc., please send it to a service branch for repair as soon as possible.

Hope it helps, give it a thumbs up! Thank you!

The main parts of the latest mobile phones are interlocked, that is, whether the main components such as the CPU are damaged, if there is no damage, it is not worth it (the most serious repair only leaves the main parts such as the CPU hard disk, and the others are replaced). If the CPU is broken, replace it with a new one (which is also equivalent to a new one).

It's not easy to say about the phone that got into the water. As long as it is said that it is after-sales or maintenance, you can take a look, after all, many electrical components are easy to corrode after water ingress and need to be cleaned.
