西門子觸摸屏開機顯示條紋多年成功修復解決；觸摸屏出現這種故障的(de)(de)時候，維(wei)(wei)修方(fang)法就跟普通液晶電視一(yi)樣了(le)。不過，西(xi)門子的(de)(de)電路(lu)(lu)板做工精細，分(fen)層很多，查(cha)電路(lu)(lu)可不一(yi)定有維(wei)(wei)修液晶電視那(nei)么(me)簡單。這就需要(yao)我們的(de)(de)維(wei)(wei)修技術(shu)人員(yuan)掌握豐富(fu)的(de)(de)電子元件(jian)(jian)知識和基(ji)礎理論，才能解決這種硬件(jian)(jian)故障。一(yi)般(ban)花屏和白屏說明電路(lu)(lu)電源工作(zuo)(zuo)是有的(de)(de)，如果觸摸管(guan)用，說明問題僅(jin)在邏輯板，如果觸摸不管(guan)用，那(nei)說明CPU系(xi)統未工作(zuo)(zuo)正(zheng)常，更進一(yi)步的(de)(de)維(wei)(wei)修分(fen)析就需要(yao)維(wei)(wei)修技術(shu)人員(yuan)實際發揮了(le)。
