What are the reasons for the full-color LED display screen? If the small-pitch full-color LED display is just installed and it is powered on, the vast majority of the reasons are because the scan of the LED software control card setting is incorrect, and the cable is not plugged in here. Correct.

  If it is because of the phenomenon of blurry screen found after using for a period of time, most of the reason is the failure of the control card. The biggest reason for the failure of the control card is the damage of the chip or power supply caused by the water seepage of the full-color LED display panel.

  If you want to solve this kind of problem, you can try to connect a DVI interface monitor, and observe whether the signal of the DVI output port of the graphics card is normal. In addition, the reason for the blurring of the small-pitch full-color LED display may also be the problem of the graphics card and the driver. If it is really a graphics card and driver problem, we suggest that you can try to replace the network cable of the receiving card behind the full-color LED display with the debug button on the receiving card to see if the display cabinet scans normally.

  The last one may be the cause of the blurring of the small-pitch full-color LED display, and I will share with you here.

  (1) The full-color LED display screen cannot be displayed. Solution: Check whether the power supply of the display screen is normal, whether there is strong current input, and will it cause a low or high level.

  (2) The full-color LED display is not normal, blurred or unclear. Solution: Check whether the parameter setting of the LED control card is correct, and whether the communication line is in normal communication.

  (3) Part of the full-color LED display screen displays abnormally, such as a black screen and a blurry screen.

   Solution: Check whether the power supply is working normally and whether the signal transmission line of the screen body is faulty.
