Today, the editor of Liancheng will share with you how to do if the image cannot be loaded during the use of the LED display.

First, check whether the jumper cap of the LED display is loose or falling off; if the jumper cap is not loose, please make sure that the direction of the jumper cap is correct. Check that the serial cable used to connect the controller is a straight-through cable, not a crossover cable. Check and confirm that the serial port cable is intact and that both ends are not loose or falling off.

Compare the LED display control software and the control card you choose to select the correct product model, correct transmission method, correct serial port number, correct baud rate, and set the control system hardware correctly according to the DIP switch diagram provided in the software address bits and baud rate.

Make sure that the LED display control system hardware is properly powered up. If it still fails to load after the above inspection and correction, please use a multimeter to measure whether the serial port of the connected computer or control system hardware is damaged. To confirm whether it should be returned to the computer manufacturer or the control system hardware should be returned for testing.

In many cases, the reasons for the black screen of the LED display screen are caused by improper operation during use. Of course, there are also reasons for the LED display screen itself, but the probability is relatively small.
