西門子TP900觸摸屏常見故障白屏修復解決,西門子顯示屏維修,西門子操作屏維修,西門子控制面板修理銷售(成功修復解決)
西門子操作(zuo)屏開(kai)機白(bai)屏故障分(fen)析; 出現白(bai)屏現象(xiang)表(biao)示(shi)(shi)背光板(ban)能正常(chang)工作(zuo),首先判斷主(zhu)板(ban)能否正常(chang)工作(zuo),可按電(dian)源開(kai)關查看指示(shi)(shi)燈(deng)有無反(fan)應,如果指示(shi)(shi)燈(deng)可以(yi)變換顏色,表(biao)明主(zhu)板(ban)工作(zuo)正常(chang)。
1、檢(jian)查主板信號輸(shu)出到屏的(de)連接(jie)線是否有接(jie)觸(chu)不良(可以替換連接(jie)線或屏)。
2、檢查主板各個工作點的電(dian)壓(ya)是(shi)否(fou)正常,特別(bie)是(shi)屏的供(gong)電(dian)電(dian)壓(ya)。
3、用示波器檢查(cha)行場信(xin)號(hao)和時鐘信(xin)號(hao)(由輸(shu)入到輸(shu)出)。
4、換上以寫程序的(de)通(tong)用板試機,如指示燈無反應或不亮,表(biao)明主板工作不正常。
