Display screen failure: A failure in the internal circuit or component of the display screen may also cause a black screen, and you need to contact a professional for repair.

Answer 2

The problem of black screen or failure to display on the P1.25 display may be caused by many factors. 

First, hardware failure is one of the main reasons, including power failure, loose or damaged connection cables, backlight failure, etc. Secondly, software problems may also cause black screens, such as improper resolution settings, outdated or damaged graphics card drivers, and incorrect operating system settings. 

In addition, external device interference or electromagnetic interference may also affect the normal operation of the display.
