Causes a short circuit on the circuit board, resulting in garbled characters. If this happens, Jianyi will immediately find a supplier or a maintenance manufacturer for maintenance.
2. Transmission data problem
The control circuit of the brain output to the screen is faulty, focus on checking the power supply and signal input parts of the screen. Such as damage to the control system board, damage to the data cable interface, and reverse connection of the data cable, etc., will cause garbled characters on the outdoor display.
3. The problem of wiring
In the case of excluding the power supply problem, test whether the power supply of the module in the defective part is normal (if the first block that is not normal is dark and bright 80%, there is a problem with the power supply).
