The consequences of burning the lamp tubes are serious. We can't switch on and off the machine continuously. The time interval between switching on and off the screen should be more than five minutes. In addition, we should avoid switching on the screen in the state of full white screen. Therefore, the impact current of the system is the largest at this time. If the ambient temperature is too high or the heat dissipation condition is not good, we should not switch on the screen for a long time. If our LED display screen often trips the power switch, At this time, we need to check the screen body and replace the power switch to ensure normal use. We should regularly check the firmness of the hanging part. If looseness occurs, we should re reinforce or update the hanging parts.
