When the LED display shows garbled characters, how can we solve the problem and solve the display failure? The following is a summary of the reasons and solutions for possible garbled characters on the LED display.
1. There may be problems with the control card or software:
1. It may be the garbled phenomenon caused by the LED display parameters not being set, then we should check the configuration parameters. In general, the default parameter is 1/4 scan.
2. If the parameter settings are correct, check whether the control card is faulty.
Second, the cable problem:
1. The power supply is not included. If the module is broken, please check whether the power supply is normal.
2. If there is dim light, there is a high possibility that the power supply will have a problem.
Third, the water problem: In many cases, a large part of the garbled characters must be caused by the water in the tank. Due to improper product protection measures or quality problems in the factory, water is likely to invade after rain, leading to circuit boards. Short circuit.
Fourth, the data transmission problem: the computer output to the LED display control circuit failure, the focus is on the display power and signal input. If the control system board is damaged, the data line interface is damaged, the data line is damaged or reversed, etc., garbled characters will appear on the LED display.
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 manufacturer as soon as possible.
