Display of time, all kinds of problems will come one after another. Experts believe that in order to solve these problems is actually quite simple, with a pair of eyes can see the fault lies.

A common fault: computer just power on the monitor when the jerky is very ill, and sometimes even the icon and the text is also not see, but a two minutes later will return to normal.

This phenomenon has occurred in wet weather, monitor internal moisture. To solve this problem, you can use food packaging in moisture-proof sand cotton string, and then turn on the monitor of the back cover, place the damp sand linked to the picture tube pipe, block, close to the tube neck and tail. In this way, even in wet weather, also no longer appears above the "wrong".

Common breakdown 2: computer power on the monitor after missing the picture only heard, dark. Have to wait several minutes to appear.

This is the picture tube, leakage, shall replace the tube block. Open the back cover you can see a picture tube at the end of a small circuit board, pipe, block on the welding in the circuit board. Carefully remove the circuit board, and then welded pipe, block, to the electronics store to buy back a same pipe, block, and then set the tube socket-welded back to the Board. Then dont put the Board back to chord a small piece of sand paper, very carefully picture tube tail after projecting pin wipe clean with sandpaper. In particular, it is necessary to note the PIN on the oxide layer, scrubbed clean will soon be a relapse. The circuit board Assembly to go back and you are done.

Three common fault: monitor screen always has a persistent interference clutter or line, and the speaker of annoying noise.

This phenomenon is mostly poor immunity to power supply. If you are too lazy to work, you can replace a new power supply. If you have sufficient ability, or you can try your own replacement power supply internal filter capacitor, which tend to be effective; if the results are less obvious, you can add a switch and change down the pipe.

Four common fault: display the video.

This problem is caused by a video card with more. If this is a new video card, it may be that the quality of the card is not good or not compatible, then there is not yet installed the correct drivers. If the old card and the addition of video memory, then it is possible that new added graphics and original graphics memory model parameter is not one.

Five common fault: display a black screen.

If the video card is damaged or monitor such as break cause no signal to the monitor, the monitor of the led is blinking prompt does not receive the signal. If the resolution is set too high, exceeding the maximum resolution of the monitor also appear black, to destroy the monitor, but now the monitor has the protection function, when the resolution exceeds the set value is automatically protected. In addition, the hardware can also cause a black screen.
