西門子觸摸屏開機顯示條紋多年成功修復解決；觸(chu)摸(mo)屏出現這種故障的(de)時候，維修方法就(jiu)跟普通液(ye)晶電(dian)(dian)視一樣(yang)了。不過，西(xi)門(men)子(zi)的(de)電(dian)(dian)路(lu)板做工(gong)精(jing)細，分(fen)層(ceng)很(hen)多，查(cha)電(dian)(dian)路(lu)可(ke)不一定有(you)維修液(ye)晶電(dian)(dian)視那(nei)么簡單。這就(jiu)需要我們的(de)維修技(ji)術人員掌握豐(feng)富的(de)電(dian)(dian)子(zi)元(yuan)件(jian)知識(shi)和基(ji)礎理(li)論，才能解決這種硬件(jian)故障。一般花屏和白(bai)屏說(shuo)明電(dian)(dian)路(lu)電(dian)(dian)源工(gong)作是有(you)的(de)，如(ru)果(guo)觸(chu)摸(mo)管(guan)用(yong)，說(shuo)明問題僅在邏輯板，如(ru)果(guo)觸(chu)摸(mo)不管(guan)用(yong)，那(nei)說(shuo)明CPU系(xi)統未工(gong)作正(zheng)常，更進一步的(de)維修分(fen)析(xi)就(jiu)需要維修技(ji)術人員實(shi)際發揮了。
