1. Linen er løs


    (1) First, check whether the serial cable used to connect to the controller is loose or has fallen off. If it turns black during the initial loading process, it is probably because the communication line was interrupted during the communication process due to the loosening of the communication line. Therefore, the screen turned black. Check it first, but it is important to solve the problem quickly.


    (2) Check and confirm whether the HUB distribution board connected to the LED screen and the main control card is tightly connected and whether it is plugged in reverse.



2. Strømforsyningsproblem



    Please make sure that all hardware including the control system has been powered on correctly. Whether the power light is flashing, whether the power supply is faulty, it is worth noting that this phenomenon is usually prone to occur when using a low-quality power supply.

The above are the reasons and solutions for the LED display that is half bright and half not bright. Check out the most likely causes one by one and locate them quickly. If it is due to a hardware failure or the problem cannot be confirmed, please contact your service manufacturer for technical support.
