1、顯示器無顯示
現象:顯示器無反(fan)應(ying),無任何圖象。
原(yuan)因(yin):造成此現象產生(sheng)的原(yuan)因(yin)很多(duo),下面逐個說明:
① 顯示器電路故(gu)障;
② 顯(xian)示器(qi)信號線與(yu)主(zhu)機顯(xian)示卡接觸不良;
③ 顯示器的電源輸入故障;
④ 計(ji)算機(ji)主機(ji)故障。
解決方法:
① 檢(jian)查顯(xian)(xian)示器(qi)前端(duan)的信號(hao)燈是(shi)否(fou)亮(liang),如不亮(liang),檢(jian)查顯(xian)(xian)示器(qi)電源(yuan)線與顯(xian)(xian)示器(qi)接觸(chu)是(shi)否(fou)正(zheng)常。
② 檢查計算機(ji)主機(ji)工作是否(fou)正常。
③ 如(ru)仍無法(fa)排除故障,請專(zhuan)業(ye)人(ren)員維修(xiu)。
