After the outdoor digital display screen restarts, the first thing we need to consider is whether the driver is correct. The white screen, i.e. the backlit display, can light up, but no other pictures will be displayed. Then, first check if the driver is correct, and then re-burn the program to judge. If the program is still the same after reburning, you can check for driver issues.
Connect the high-brightness outdoor LCD screen, and use a multimeter to measure whether the power supply voltage at the FPC connection is normal. If the voltage is OK, check the timing signal in the driver circuit. If not, check for damage to the open fuse resistor near the FPC. If damaged, replace electronics.
Any problem with the bright outdoor LCD screen, we can't ignore whether there is a bad contact or disconnection. Check whether the cable is plugged in properly, or the cable has poor contact due to dust entering the cable due to prolonged use.
