西門子TP1200屏面板觸摸功能壞按鍵失效修復解決(jue)故障分析處理;
觸摸(mo)失效,安靜無(wu)反應;
這(zhe)是(shi)(shi)和人手(shou)接觸較多的(de)(de)地(di)方(fang),也是(shi)(shi)容(rong)易出問題的(de)(de)表面層,一般這(zhe)類型(xing)的(de)(de)故(gu)障是(shi)(shi)由于用戶方(fang)人員比較粗(cu)魯動作引(yin)起(qi)的(de)(de),也有(you)由于運輸等不小(xiao)心造成,結果一般都(dou)是(shi)(shi)破碎,偶爾也可(ke)能發生(sheng)(sheng)里邊(bian)電阻等器件斷(duan)裂,這(zhe)種故(gu)障只有(you)換(huan)觸摸玻璃,因(yin)為各種廠家生(sheng)(sheng)產時候(hou)規范標準不同,所(suo)以(yi)往往更(geng)換(huan)的(de)(de)時候(hou)存在“開(kai)模"這(zhe)樣的(de)(de)過(guo)程(cheng),一旦開(kai)好了模,那么觸摸屏維修是(shi)(shi)很(hen)簡單的(de)(de)事情了,就是(shi)(shi)更(geng)換(huan)了。
下(xia)位機通訊(xun)程序(xu)沒(mei)有設定(ding)對、人機界面系統地址(zhi)沒(mei)有正確(que)、通訊(xun)口燒毀、通訊(xun)線路短線或者沒(mei)有接對線路,接觸不良等都會造(zao)成通訊(xun)故障。
一(yi)般(ban)是(shi)(shi)液晶顯示和玻璃(li)對(dui)應的按鈕等(deng)位(wei)置(zhi)偏(pian)移造成的,也有是(shi)(shi)觸摸(mo)玻璃(li)老(lao)化造成,前者可(ke)以根據人機界面廠家提供(gong)的“校正中(zhong)心點"功能重(zhong)新校正就可(ke)以了,后者需要更換觸摸(mo)玻璃(li),也有一(yi)些是(shi)(shi)接觸不(bu)良(liang)造成的,清洗一(yi)下(xia)就可(ke)以解決(jue)問題。

觸(chu)(chu)摸屏按鍵(jian)(jian)損(sun)壞(huai)故障分析(xi)維修(xiu)總結:以下是(shi)觸(chu)(chu)摸屏按鍵(jian)(jian)損(sun)壞(huai)故障的(de)分析(xi)維修(xiu)方法
觸摸屏(ping)屏(ping)幕閃爍(shuo)故障檢測維修
1.檢查(cha)觸(chu)摸(mo)屏電(dian)源,電(dian)壓。一(yi)般電(dian)源故障多一(yi)些。
2.檢查觸摸屏(ping)電(dian)源(yuan)(yuan)板是否正(zheng)常,電(dian)源(yuan)(yuan)不供電(dian)當然會出(chu)現閃屏(ping)。
3.檢查(cha)觸摸屏高壓(ya)板是否存在故障(zhang)。
4.檢查屏(ping)幕(mu)電(dian)線電(dian)纜,問題這個故障**基礎(chu),只要仔(zi)細檢查就(jiu)可以了。
5.檢測觸摸(mo)屏主板。
以(yi)上5點的檢測方向中電(dian)(dian)(dian)(dian)(dian)源(yuan),電(dian)(dian)(dian)(dian)(dian)壓,電(dian)(dian)(dian)(dian)(dian)線(xian)對這個故(gu)障(zhang)的影響很(hen)大,一(yi)般觸摸屏(ping)只要電(dian)(dian)(dian)(dian)(dian)壓正常(chang),上電(dian)(dian)(dian)(dian)(dian)后屏(ping)幕(mu)會出現(xian)國(guo)文,如(ru)果有(you)觸摸功能,點擊(ji)觸摸蜂鳴器發出聲音,觀察(cha)畫面(mian)就會跳轉。同樣,在相(xiang)反(fan)的情(qing)況下,在供(gong)電(dian)(dian)(dian)(dian)(dian)后出現(xian)閃屏(ping),這很(hen)可能是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)壓異常(chang)。首先(xian),檢查(cha)電(dian)(dian)(dian)(dian)(dian)源(yuan)問題。停電(dian)(dian)(dian)(dian)(dian)有(you)很(hen)多(duo)種。然(ran)后,先(xian)檢查(cha)電(dian)(dian)(dian)(dian)(dian)源(yuan)是(shi)(shi)否有(you)限流。如(ru)果電(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian)過長,會出現(xian)電(dian)(dian)(dian)(dian)(dian)壓下降,這與實際(ji)功率一(yi)致,也會造(zao)成閃屏(ping)故(gu)障(zhang)。不出所料,可以(yi)推斷,發現(xian)電(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian)太長,閃存屏(ping)幕(mu)不是(shi)(shi)原來的電(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian),更換了標準電(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian),通(tong)電(dian)(dian)(dian)(dian)(dian)后開機才(cai)能正常(chang)工作。
