Extended Information: Common Failures of Computer Monitors:

1. When the computer is just turned on, the screen of the monitor shakes very much: this phenomenon mostly occurs in wet weather, which is due to the moisture inside the monitor. To solve this problem completely, you can use the moisture-proof sand from the food packaging to string it with cotton thread, then open the back cover of the monitor and hang the moisture-proof sand near the end of the CRT neck near the tube base.

2. Black screen after the computer is turned on: This is caused by leakage of the picture tube header, and the tube head must be replaced. Removing the back cover reveals a small circuit board at the end of the picture tube, and the socket is soldered to the board.

Unplug the board, solder the header, and solder the new header back to the board. Then find a small piece of sandpaper and wipe the pins that protrude from the end of the picture tube with sandpaper.
