1、顯示器無顯示
現象:顯示器(qi)無反應,無任何(he)圖象。
原因(yin):造成此現(xian)象(xiang)產生的原因(yin)很多,下(xia)面逐個(ge)說(shuo)明(ming):
① 顯示器電路故(gu)障(zhang);
② 顯(xian)示器信號(hao)線與主(zhu)機顯(xian)示卡接觸(chu)不良;
③ 顯示器(qi)的電(dian)源輸(shu)入故障;
④ 計算機主機故障。
解決方法:
① 檢查顯示器(qi)(qi)前(qian)端(duan)的信號燈是(shi)否亮,如(ru)不亮,檢查顯示器(qi)(qi)電(dian)源線與顯示器(qi)(qi)接觸是(shi)否正常。
② 檢查(cha)計算機(ji)主機(ji)工作是(shi)否正常。
③ 如仍無(wu)法排除故(gu)障,請專業人(ren)員維(wei)修。
