1、 Power supply
Check if the power indicator light behind the splicing screen is on. If it is on, it indicates that the power supply is working properly.
2、 Board
It can be judged from the display color of the indicator light, where the green light is working and the red light is in the stopped state. If the light is green, it indicates that the board is also working properly. If it is a red light, the board may not be working, and sometimes it may not start properly. You can restart the machine or reinsert the board's ribbon cables.
3、 Screen
If the board malfunction is resolved and the screen still appears black, it may be due to a problem with the screen itself. In this case, it is recommended to contact after-sales personnel for repair.
