In wet weather, the LCD screen turns black and the power light goes out.

But the inside of the display is wet, and a large amount of water vapor leads to short circuit. Adjust the temperature with an air duct and blow it into the mesh at the bottom of the back of the monitor for about one minute. Blow out steam, wait for the monitor to cool, and then try to plug in the monitor. If it is blown at high temperature, stop for a few seconds and cool the display screen to prevent the high temperature from melting. It's very humid these days, and my mainframe doesn't respond from time to time. I can blow dry the inside of the main engine with a ventilation pipe to start it normally.
