What to do if LED Pixel lamp bead display system fails ?

In the process of using full-color LED display equipment with LED Pixel lamp display, it is inevitable that sometimes there will be failure problems. Today, we will introduce how to distinguish and judge the fault diagnosis method of full-color LED displays.


Step 1: Check whether the graphics card setting part is set well. The setting method according to your needs is in the CD-ROM electronic file, please refer to it.
Step 2: Check the basic connections of the system, such as the DVI cable, the network cable socket being correct, the connection between the main control card and the computer PCI socket, the serial port cable connection, etc. The connection method has a legend, please refer to it carefully
Step 3: Check whether the computer and LED power system meet the needs of users. When the power supply of the LED screen body is insufficient, when the LED Pixel lamp display is close to white (a lot of power consumption), it will cause the screen to flicker, and the appropriate power supply is prepared according to the power supply requirements of the box.
Step 4: Check whether the green light of the sending card flashes regularly, and then go to step 6. If it does not flash, restart it. Before entering win98/2k/XP, check whether the green light flashes regularly. If it flashes, go to step 2. Please check whether the DVI cable is connected well. If the problem is not solved, one of the sending cards, graphics card, and DV cables is faulty, please replace it and repeat step 3.
Step 5: Please follow the software instructions to set up or re-install and then set up until the LED Pixel lamp display of the sending card flashes, otherwise repeat step 3.
Step 6: Check whether the green light (data light) of the receiving card flashes synchronously with the green light of the sending card. If it flashes, go to step 8 to check whether the red light (power) is on. If it is on, go to step 7, if it is off, check the yellow light (power). Protection) is on, if not, check whether the power supply is reversed or the power supply has no output. If it is on, check whether the power supply voltage is 5V. If it is, turn off the power supply, remove the adapter card and the cable and try again. If the problem is not solved, the receiving card is faulty. , replace the receiving card, and repeat step 6.
Step 7: Check whether the network cable is well connected or too long. (the standard Category 5 network cable must be used, the distance between the network cable without a repeater is less than 100 meters), and check whether the network cable is made according to the standard (please refer to the system installation and settings), If the problem is not resolved because the receiving card is faulty, replace the receiving card and repeat step 6.
Step 8: Check whether the power light of the large screen is on. If not, go to Step 7 to check whether the interface definition line of the adapter card matches the unit board. Note: After most of the screens are connected, there may be no screen or blurry screen in some cabinets. Because the RJ45 interface of the network cable is not firmly connected. Or the power supply of the receiving card is not connected, the signal is not transmitted, so please re-plug The network cable (or exchange). Or plug in the receiving card power supply (pay attention to the direction) can solve the problem
