people who are sick, not to mention the machine. Computer monitor strikes are often things, some are not really bad, but occasionally a little temper, we have a way to deal with such failures, and often have some minor faults, let us learn now. Common fault one: The screen of the monitor is very shaken when the computer is turned on. Sometimes even the icons and texts are not clear, but it will return to normal after a minute or two. This phenomenon occurs mostly in humid weather and is caused by moisture inside the monitor. To completely solve this problem, use the moisture-proof sand in the food packaging to string together with the cotton thread, then open the back cover of the display and hang the moisture-proof sand near the neck of the tube tube near the tube seat. In this way, even in wet weather, the above "faults" will no longer occur. Common fault 2: After the computer is turned on, the monitor only smells its sound and is dark. It takes a few tens of minutes to appear. This is due to the leakage of the display tube socket. The tube holder must be replaced. Disassemble the back cover to see a small circuit board at the end of the tube, and the tube holder is soldered to the board. Carefully unplug the board, solder the header, go back to the electronics store and buy the same header, then solder the header back to the board. At this time, don't rush to put the board back. You should first find a small piece of sandpaper. Carefully wipe the pins protruding from the rear of the tube with a sandpaper. In particular, pay attention to the oxide layer on the pin. If it is not cleaned, the old disease will recur. Put the board back and you're done. Common fault 3: There are always lingering interference clutter or lines on the display screen, and there are also annoying noises in the speakers. This phenomenon is mostly caused by poor anti-interference of the power supply. If you are too lazy to do so, you can replace it with a new one. If you have enough hands-on ability, you can try to replace the filter capacitor inside the power supply. This can often work. If the effect is not obvious, you can replace the switch tube. Common fault four: the display screen. This problem is mostly caused by the graphics card. If it is a newly changed graphics card, it may be that the card quality is not good or incompatible, and then there is no correct driver installed. If the old card is added with video memory, it may be caused by the newly added video memory and the original memory model parameters. Common fault five: the display is black. If there is no signal transmission to the display due to damage to the graphics card or display disconnection, the indicator light of the display will flash continuously to indicate that no signal is received. If the resolution is set too high, a black screen will appear if the resolution exceeds the maximum resolution of the display. If the display is destroyed, the current display has a protection function that automatically protects when the resolution exceeds the set value. In addition, hardware conflicts can also cause black screens.
