西門子觸摸屏上電進不去操作系統修完程序在

程序(xu)加(jia)載不(bu)過去，卡死不(bu)動(dong)-首先排除軟件(jian)原因(yin)，可以(yi)使(shi)用(yong)軟件(jian)進行(xing)恢(hui)(hui)復(fu)出(chu)廠(chang)設置(zhi)(zhi)的操作(zuo)。如(ru)果不(bu)能(neng)進行(xing)恢(hui)(hui)復(fu)出(chu)場設置(zhi)(zhi)或者(zhe)恢(hui)(hui)復(fu)出(chu)場設置(zhi)(zhi)后還是(shi)同(tong)樣的現象。那就是(shi)硬件(jian)問題。只能(neng)送修

故障(zhang)維修(xiu)一例(li)：這(zhe)臺(tai)機器(qi)是用在可(ke)(ke)口(kou)可(ke)(ke)樂公司水處理設(she)備上的，觸摸屏用了三年還非(fei)常新，一點灰塵也(ye)沒有(you)，可(ke)(ke)見工作環境很好。供上24V電(dian)源(yuan)后開機沒有(you)任(ren)何反應(ying)，檢查(cha)電(dian)路(lu)(lu)(lu)(lu)供電(dian)沒有(you)錯誤，監測(ce)(ce)電(dian)壓(ya)(ya)也(ye)沒有(you)下降，說明人機界面內(nei)部沒有(you)短路(lu)(lu)(lu)(lu)。開蓋后測(ce)(ce)量(liang)電(dian)壓(ya)(ya)有(you)進(jin)入主電(dian)源(yuan)電(dian)路(lu)(lu)(lu)(lu)，但是沒有(you)變成12V和5V輸出，所以開機后屏沒有(you)任(ren)何反應(ying)。將電(dian)路(lu)(lu)(lu)(lu)板(ban)翻過來測(ce)(ce)量(liang)時發現，有(you)顯示水痕(hen)腐蝕，電(dian)路(lu)(lu)(lu)(lu)線路(lu)(lu)(lu)(lu)都開路(lu)(lu)(lu)(lu)了。修(xiu)補后試機正(zheng)常。MP377程序(xu)加載不過去、卡(ka)死的原因兩(liang)種：軟件或者(zhe)硬(ying)件。
