How to repair the LED display screen is not bright?
 

1. The unit board is not bright: check the power supply of the lower unit board in turn, and repair the lower circuit if the power supply is abnormal; Check whether the data line is damaged, and replace the data line in time if it is the problem of the data line. Check whether the chip is broken, and replace the chip if it is broken.

 

2. Some unit boards are always on and some are not: for example, if there is a problem with the data line, you need to plug and unplug in the direction again; For example, if the distribution board is abnormal, you can try to replace the distribution board. For example, if a unit board fails, replace the defective unit board in time.
 

 

3. The whole screen is not bright: in case of this kind of problem, it is necessary to find out the cause of the problem first, and then suit the remedy to the case according to the cause of the problem. For example, if the power supply of the control card is damaged, replace it with a new power supply. If it is a circuit problem, directly repair the circuit. There is another possibility that there is a problem with the computer setting data, and the control system should be debugged again.

 

4. The whole screen is not interlaced: This situation is mostly due to the network cable problem. You can check whether the lower network cable is plugged in properly. If it is the network cable head clamped by yourself, the problem that is easier to ignore is that the crystal head is not clamped properly. After pulling out one or more copper cores in the network cable, the network cable is blocked or has poor contact.
