Check if internal wiring of the display is messy or if insufficient internal space leads to mutual internal signal interference. Resolve it by tidying up internal flat cables, cutting down on excessive flat cables and wires, and adding magnetic rings.
Usually due to power supply current overload. Suggest reducing the power cord's load modules or using a higher-wattage power supply.
This issue is usually due to excessively high input voltage at the power supply's I/O terminals, causing the filter capacitor in the internal rectifier circuit to explode. Before powering on, check if the wiring is correct and whether the AC supply voltage has high harmonic voltage components.
When the voltage of the LED power supply is unstable, it is common for the display screen to suddenly go black momentarily. 1)Loose signal cable 2)Over-temperature protection triggered 3)The video cable is abnormal
Connect the output terminals V+ and V- in parallel, and then connect them to the display module. Connect the current sharing control lines EC between the power supplies in parallel. There is also a PG fault detection line. The normal voltage of this line is 3.3V, and it will be at a low level in case of a fault. VO is the output voltage detection line, which is equal to the V+ voltage. If the VO detection and PG functions are not required, the ports should be left unconnected.
