When using the LED display, we sometimes have a black screen in the process of controlling the system. What is the reason for this? I think most people will have such questions. It was working fine at first, but then the screen went black all of a sudden? Of course, this phenomenon cannot be explained clearly at the moment. This phenomenon may be caused by various reasons. In the process of using the LED display, it will also vary due to different operations or different environments. For example: it is black as soon as it is plugged in. Maybe it turns black during the loading process. These reasons are related to a certain extent.

When encountering this phenomenon, how can we judge the black screen of the LED display? The following mainly looks at this failure from five aspects.

1. Make sure that all hardware, including the control system, is powered on correctly, and do not connect them reversely or incorrectly.

2. Check and confirm whether the 40mm Flexible LED Mesh Curtain display screen and the HUB distribution board connected to the main control card are tightly connected and inserted reversely.

3. Check and reconfirm whether the serial cable used to connect to the controller is loose or falls off.

4. Please check and confirm whether the 50-core cable connecting the Lingxin control card and the HUB distribution board is loose or reversed.

5. If the interface definition of your display does not match the provided HUB board, a black screen will appear. Please recheck your jumper for looseness, open circuit or short circuit.

The above are 5 solutions, as long as you check the above aspects carefully when the black screen appears, then the black screen problem will be solved naturally!
