LED electronic display system troubleshooting and repair steps?

Step 1: check whether the setting part of the video card is set properly. The setting method is available in the CD-ROM electronic file as required. Please refer to.

Step 2: check the basic connection of the system, such as DVI cable, whether the network cable socket is correct, the connection between the main control card and the PCI connector of the computer, and the connection of the serial port cable.

Step 3: check whether the computer and LED power supply system meet the use requirements. When the power supply of LED electronic display screen is insufficient, when the display is close to white (more power consumption), the screen will flash, and appropriate power supply shall be configured according to the power demand of the box.

Step 4: check whether the green light of the sending card flickers regularly. If it does not, restart it. Before entering WIN98 / 2K / XP, check whether the green light flickers regularly.

If not, check whether the power supply is connected reversely or the power supply has no output. If it turns on, check whether the power supply voltage is 5V. If it turns off the power supply, remove the transfer card and Line up and try again. If the problem is not solved, replace the receiving card and repeat step 6.

If the problem is not solved, replace the receiving card, and repeat step 6.
