西門子(zi)按鍵屏開機(ji)無顯示不(bu)亮送修-3小時解(jie)決恢復處理方法
西門子按鍵屏開機黑屏不顯示故障分析處理:
方案(an)一:
1、先判斷屏(ping)線(xian)路(lu)是否通電,查(cha)看屏(ping)電源燈和顯示器是否亮燈,如(ru)果不亮對電源線(xian)路(lu)進行(xing)更換嘗試排除(chu)電源線(xian)的問題(ti)
2、如果電源線沒有問(wen)題,顯(xian)示器(qi)也(ye)正常亮燈,那么可能是(shi)(shi)電源出現(xian)問(wen)題,再繼續深入檢(jian)測(ce)主(zhu)機上面的硬(ying)(ying)件(jian)(jian),看(kan)下硬(ying)(ying)件(jian)(jian)是(shi)(shi)否(fou)接觸(chu)不良或者元(yuan)件(jian)(jian)壞了,也(ye)可以(yi)嘗試對主(zhu)機各(ge)部件(jian)(jian)進(jin)行(xing)灰塵清(qing)理,再排除硬(ying)(ying)件(jian)(jian)是(shi)(shi)否(fou)出現(xian)松動。

方案(an)二:
1、當打開電(dian)(dian)(dian)腦后,過了幾(ji)分(fen)鐘后還沒有圖像(xiang)出現。這時(shi)應(ying)該(gai)首(shou)先看看顯示(shi)(shi)器(qi)面板(ban)上(shang)的(de)電(dian)(dian)(dian)源指示(shi)(shi)燈是(shi)否(fou)(fou)亮(liang)。如(ru)果(guo)不(bu)亮(liang)再檢(jian)查顯示(shi)(shi)器(qi)的(de)電(dian)(dian)(dian)源插頭是(shi)否(fou)(fou)接(jie)好。如(ru)果(guo)電(dian)(dian)(dian)源線插接(jie)良好(要(yao)保證(zheng)電(dian)(dian)(dian)源插座(zuo)有電(dian)(dian)(dian),可以換一(yi)個插孔試(shi)一(yi)下),并且電(dian)(dian)(dian)源開關是(shi)開著的(de),但(dan)顯示(shi)(shi)器(qi)指示(shi)(shi)燈不(bu)亮(liang),這說明顯示(shi)(shi)器(qi)內部電(dian)(dian)(dian)路有故障,這時(shi)應(ying)該(gai)送專門的(de)維(wei)修部門修理。
2、如果(guo)顯示器的電(dian)源指(zhi)示燈亮(liang),這時(shi)應該(gai)重新啟動(dong)電(dian)腦,并注意(yi)主(zhu)(zhu)(zhu)機的指(zhi)示燈是否(fou)(fou)閃亮(liang),主(zhu)(zhu)(zhu)機里是否(fou)(fou)有“嘀"的一聲(sheng)。如果(guo)有說(shuo)明(ming)電(dian)腦已經(jing)正常(chang)(chang)啟動(dong)。這時(shi)應檢查顯示器與(yu)主(zhu)(zhu)(zhu)機的信(xin)號線(xian)連(lian)(lian)接是否(fou)(fou)正常(chang)(chang),和主(zhu)(zhu)(zhu)機相(xiang)連(lian)(lian)的15針(zhen)D形插頭(tou)是否(fou)(fou)松動(dong),插頭(tou)內(nei)的針(zhen)是否(fou)(fou)有斷、歪、短等(deng)情況。如果(guo)連(lian)(lian)接正常(chang)(chang),說(shuo)明(ming)顯示器內(nei)部有故障,應送修。
觸(chu)摸(mo)屏(ping)黑(hei)屏(ping)是觸(chu)摸(mo)屏(ping)的常見故(gu)障(zhang)(zhang),所以(yi)在觸(chu)摸(mo)屏(ping)使(shi)用(yong)過程中(zhong)注(zhu)意使(shi)用(yong)事項,減少故(gu)障(zhang)(zhang)的發(fa)生(sheng)。如若發(fa)生(sheng)故(gu)障(zhang)(zhang),應送至專(zhuan)業的維(wei)修中(zhong)心維(wei)修。
