Q: What is the reason why part of the LED display is displayed and part is not displayed?

This fault is generally caused by the signal loss of the LED display. The reasons for the signal loss are generally: 1. According to the direction of the wiring, the network cable connected to the receiving card of the normal display box and the receiving card of the black screen box itself cannot communicate with the signal. , Replacing the network cable can solve the problem. 2. The power supply connected to the receiving card fails, resulting in no power supply to the receiving card. In this case, replace the power supply and restore the wiring to the original state to solve the problem. 3. The receiving card itself is faulty, replace the receiving card to solve the problem.

Q: Why a single LED module does not light up on the whole screen?

Check whether the 5V power line connected to the LED module is disconnected or loose. Check if there is any problem with the wiring. If the 5V power cable is not loose and there is no problem with the wiring, replace the LED module. If the fault persists after replacing the LED module, it is the problem of the receiving card. Replace the receiving card.

Q: What is the reason for the inconsistent color rendering of small squares on the LED module?

This fault is generally a fault in the module IC, just replace the faulty LED module.

Q: What is the reason for the fuzzy picture displayed on the LED screen?

1. The setting of the sending card is wrong. Restore the default settings of the sending card. 2. The FPGA program of the receiving card does not support the driver IC on the LED display. Upgrade the FPGA program of the receiving card.

Q: Why are some images not displayed on the LED screen after sending the multi-screen file?

The loading points of the receiving card in the continuous screen file are inconsistent with the actual loading points of the receiving card. Carefully check the loading points of the receiving card in the connection screen file, correct it, and try again.

Q: Why is a single receiving card displayed normally, but the entire screen is not displayed in the correct area?

1. There is no file for loading the entire screen of the LED display. It is necessary to make and load the LED display screen connection file. 2. The screen file created is wrong. The wiring method of the screen-connected file does not match the actual wiring method, and a correct screen-connected file needs to be created and loaded.
