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:
