台式电脑屏幕老是闪烁解决方法怎么解决台式电脑屏幕闪烁 Recently opened the computer, the screen will start flashing, a dark one bright, always flashing incessantly, don't know is wrong, also don't know what to do. Is it right? Have many friends and I also encountered the same situation? Look together computer master is how to explain the causes and coping methods.

　　一、电脑刚开机时显示器的画面抖动得很厉害，有时甚至连图标和文字也看不清，但过一二分钟之后就会恢复正常。这种现象多发生在潮湿的天气，是显示器内部受潮的缘故。

　　Float a, just getting on the computer too much, and sometimes even the icons and text are not clear, but after one or two minutes will return to normal. This phenomenon occurred in wet weather, is to monitor http://www.mkykgw.com/ the internal moisture.

　　解决方法：要彻底解决此问题，可使用食品包装中的防潮砂用棉线串起来，然后打开显示器的后盖，将防潮砂挂于显象管管颈尾部靠近管座附近。这样，即使是在潮湿的天气里，也不会再出现以上的“毛病”。

　　Solution: to solve this problem, can be used in food packaging moisture-proof sand string together with cotton thread,http://www.sanbenshu.net/ and then open the back cover of the display, will hang in the damp sand picture tube neck near the base near the tail. In this way, even in wet weather, also won't appear above "".

　　二、你的电源工作不稳定，热性能不好或抗干扰性能差，导致输出电压纹波过大，使显卡处于无法正常工作的状态，导致屏闪，此种问题多以热性能不好居多。

　　Two, the power of your work is not stable, thermal performance is not good or poor anti-interference performance,http://www.jiyinyugen1.com/ leading to the output voltage ripple is too large, so that the card is not working properly, causing screen flicker, this kind of problem in the thermal performance is not good.

　　解决方法：打开电源更换其开关管，滤波电容，或直接换电源。

　　Solution: turn on the power to replace the switch tube, filter capacitor, or directly for power.

　　三、显示器的行管性能不良，导致高压过高，屏幕太亮变白成一片，亮度电位器氧化严重，阻值变小或接触不良，电路的故障导致显示器彩管的加速极电压过高或阴极电压过低，都会造成这种电脑屏幕闪烁的现象，特别是初期现象和你现在的问题极其相似。

　　Three, display tube bad performance,http://www.dgfuai.com/ leading to high pressure is too high, the screen is too bright white as a sheet, luminance potentiometer serious oxidation resistance, small or poor contact, the circuit fault leads to accelerated display color voltage is too high or the cathode voltage is too low, will cause the computer screen flicker phenomenon, especially in the initial phenomenon and your problem now is very similar.

　　解决方法：开机等出现屏闪现象，拍打显示器看现象有否加重(停下来过后的现象，不要用太大的力气)。加重则显示器的问题，多是以上部位接触不良所致，需找专业人士修理，无则不是此处问题。

　　Solution: boot appeared screen flicker phenomenon, beat display phenomena whether increased (stopped after the phenomenon, do not use too much effort). Increase the display problem, is above the site due to poor contact, the need to find professionals to repair, no is not the problem.

　　四、显卡接口接触不良，显卡的热性能不良，还有显示器连线接触不好等。

　　Four, the graphics interface is bad, bad thermal performance of graphics, and display line contact is not good.

　　解决办法：

　　The solution:

　　1、拔下显卡，检查接口是否有锈蚀，用无水酒精擦干净，同时略把其弹片翘起一些。

　　1, unplug the card, check whether the corrosion interface, anhydrous alcohol wipe clean, also omitted the shrapnel up some.

　　2、等现象出现之后立即关机，用纯棉手套或棉布拔下显卡，用手试显卡芯片是否过热(一般是略温)，过热换风扇，或换芯片、显卡。3、用万用表电阻挡R*1K挡测试显示器连线是否接触良好，测试时要晃动着线，其坏的可能性较小。

　　After 2, wait for a phenomenon immediately shut down, with cotton gloves or cloth unplug the card, try the graphics chip by hand is overheating (generally slightly warm), overheating for the fan, or change the chip, the card. 3, using a multimeter resistance gear R*1K gear test display connection is good contact, when testing swaying line, the less likely to bad.
