What about the black screen of Xiaomi 8 mobile phone screen?

If the black screen of the mobile phone screen can't light up, the following methods can be used to troubleshoot:

1. If the screen is blank during the call (long press the power button can force a restart), after the restart, enter the hardware detection mode to calibrate the distance sensor.

2. Try to plug in the charging cable and see if the breathing light lights up:

A. If the breathing light lights up, you can try to press and hold the power button 10S or more to forcibly restart the mobile phone to see if the display is normal. This is an accidental phenomenon, which is caused by the abnormality when the program performs some program operations. Users are advised to restore the factory settings after backing up the data and check whether the mobile phone is normal without restoring the backup. After the phone restarts and restores the factory settings (the backup is not restored), the phone will still have a black screen. It is recommended to try again after brushing the line.

B. If the breathing light doesn't light up, press the power button for more than 10S, and the mobile phone doesn't respond. It is recommended to take the mobile phone to Xiaomi Authorized Service Center for testing.
