1. There may be a problem with the control card or software:
1. The garbled code may be caused by not setting the LED display parameters. At this time, we should check the configuration parameters. In general, the default parameter is 1/4 scan.
2. If the parameter settings are correct, check if there is a problem with the control card
Second, the wiring problem:
1. Eliminate the power supply, if there is a bad module, check whether the power supply is normal
2. If it appears dark and bright, it is highly likely that there is a problem with the power supply
3. Water ingress problems: In many cases, a large part of the garbled codes must be caused by water in the cabinet. Due to improper protective measures or quality problems of the factory products, it is likely to be invaded by water after rain, which may cause circuit boards. Short circuit
Fourth, the problem of data transmission: The control circuit of the computer output to the LED display is faulty, and the focus is on the power supply and signal input of the display. If the control system board is damaged, the data cable interface is damaged, the data cable is damaged or connected reversely, etc., it will cause the LED display to appear garbled.
Garbled characters are a common problem of LED displays. If you encounter such a problem, don't be nervous. Check the above reasons. If the problem is still not resolved, please contact the LED display after-sales manufacturer as soon as possible.
