3. Check and confirm whether the connection between the LED display screen and the HUB distribution board connected to the main control card is tightly connected and whether it is inserted reversely.


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


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