How To Solve The Problem Of LED Display Screen Flickering? | ZHANXIN

In short word, all the elements in LED control system may be the root of LED screen flickering problem. For instance, video source, LED controller, LED display itself, receiving card, flat cable, and so on. As we have so many potential reasons of LED screens flickering, we have to find out a more accurate method to fix the issue.

 The first step is, figuring out whether the flickering is fixed on the screen, or happens randomly on the whole screen. First of all, we must have a basic conception that the fixed problem may happen on module level, cabinet level and output level.

Output Level

When the issue is output level, we need to change to other output port, if the problems stay on the same output port, then that may be sending card output issues. If the problem switches to the new output port, then that may be raised by Ethernet cable.

Cabinet Level

Please go to check the firmware and receiving card parameter. If the values are same with other normal receiving card, then replace the issuing receiving card with a normal one. If they are not the same, please make them same with other normal receiving card. However, if there are still problems after changing the wrong receiving card, then go to check the cabinet hardware such as HUB board.

Module Level

Please go to check the HUB board connector or flat cables.
