臺(tái)式電腦屏幕老是閃爍解決方法 怎么解決臺(tái)式電腦屏幕閃爍 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、電腦剛開(kāi)機(jī)時(shí)顯示器的畫(huà)面抖動(dòng)得很厲害，有時(shí)甚至連圖標(biāo)和文字也看不清，但過(guò)一二分鐘之后就會(huì)恢復(fù)正常。這種現(xiàn)象多發(fā)生在潮濕的天氣，是顯示器內(nèi)部受潮的緣故。

　　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.

　　解決方法：要徹底解決此問(wèn)題，可使用食品包裝中的防潮砂用棉線串起來(lái)，然后打開(kāi)顯示器的后蓋，將防潮砂掛于顯象管管頸尾部靠近管座附近。這樣，即使是在潮濕的天氣里，也不會(huì)再出現(xiàn)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、你的電源工作不穩(wěn)定，熱性能不好或抗干擾性能差，導(dǎo)致輸出電壓紋波過(guò)大，使顯卡處于無(wú)法正常工作的狀態(tài)，導(dǎo)致屏閃，此種問(wèn)題多以熱性能不好居多。

　　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.

　　解決方法：打開(kāi)電源更換其開(kāi)關(guān)管，濾波電容，或直接換電源。

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

　　三、顯示器的行管性能不良，導(dǎo)致高壓過(guò)高，屏幕太亮變白成一片，亮度電位器氧化嚴(yán)重，阻值變小或接觸不良，電路的故障導(dǎo)致顯示器彩管的加速極電壓過(guò)高或陰極電壓過(guò)低，都會(huì)造成這種電腦屏幕閃爍的現(xiàn)象，特別是初期現(xiàn)象和你現(xiàn)在的問(wèn)題極其相似。

　　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.

　　解決方法：開(kāi)機(jī)等出現(xiàn)屏閃現(xiàn)象，拍打顯示器看現(xiàn)象有否加重(停下來(lái)過(guò)后的現(xiàn)象，不要用太大的力氣)。加重則顯示器的問(wèn)題，多是以上部位接觸不良所致，需找專業(yè)人士修理，無(wú)則不是此處問(wèn)題。

　　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、顯卡接口接觸不良，顯卡的熱性能不良，還有顯示器連線接觸不好等。

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

　　解決辦法：

　　The solution:

　　1、拔下顯卡，檢查接口是否有銹蝕，用無(wú)水酒精擦干凈，同時(shí)略把其彈片翹起一些。

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

　　2、等現(xiàn)象出現(xiàn)之后立即關(guān)機(jī)，用純棉手套或棉布拔下顯卡，用手試顯卡芯片是否過(guò)熱(一般是略溫)，過(guò)熱換風(fēng)扇，或換芯片、顯卡。3、用萬(wàn)用表電阻擋R*1K擋測(cè)試顯示器連線是否接觸良好，測(cè)試時(shí)要晃動(dòng)著線，其壞的可能性較小。

　　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.
