Indoor full color LED display system failure how to do?
In the use of indoor full-color LED display equipment in the process, it is inevitable that the LED display system failure problems. Today, we will introduce how to distinguish and judge the full color LED display fault diagnosis method.
1th Step: Check the video card Setup section is set up, according to the need to set the method in the CD electronic file, please refer to.
2nd Step: Check the system basic connection, such as DVI line, network cable socket is correct, the main control card and computer PCI plug the connection, serial line connection, connection method already has the legend, please consult carefully. 3rd Step: Check the computer and LED power supply system to meet the needs of the use.
When the LED screen body power supply is insufficient, when the display close to the white (more power consumption) will cause the screen flicker, according to the box supply needs of the appropriate supply power supply. 4th step: Check the transmission card green light is a regular flashing, flashing to the 6th step, if not flashing, reboot, did not enter the win98/2k/xp before checking the green light is a regular flashing, such as flashing to the second step, please check the DVI line connection is good, if the problem is not resolved for the sending card,
The video card and DV line I have one of the faults, please replace the 3rd step after each replacement.
5th step: Please follow the software instructions to set or reinstall after setting, until the sending card green flashing, otherwise repeat the 3rd step.

Note: Most of the screen body is connected, there may be a local box without screen or flower screen, as a result of the network cable RJ45 interface connection is not strong, or the receiving card power supply is not connected, resulting in the signal did not pass, so please reseat the network cable (or switch), or plug in the receiving card power (note the direction) can solve the problem. After reading this article, I believe that the indoor Full-color LED display system failures have a certain treatment heart got
