2、WEINVIEW威綸通MT6100i觸摸屏維修處理過程
當我們拿到客戶威綸通觸摸屏之後，首先用萬用表大致測了一下24V電源輸入端與地之間阻值（2兆多歐姆），bucunzaiduanluxianxiang，ranhouwomendakaiweiluntongchumopinghougai，cedianyuanbaoxiansishifousunhuai，jieguoxianshizhengchang。zheshihouwomenjiuxuyaogeiweiluntongchumopingjiadianceshidianyuandianluyouwuguzhang，jieguodianyuandengzhengchang，jiezheshiyongshoudianjianzhaoping，nengkandaopingshangdehuamianneirong，shuominglexinhaoqudongbanzengjinggongzuobingqiezhengchangshuchulexinhao，pingxianxinpianyechubupandingzhengchang。
到此，這種情況就看是燈管還是高壓的問題了。（高壓板壞掉就是一整塊黑板，不會有任何變化。大多高壓板損壞，是會呈現一亮就滅的缺點的“如：12V供電處的主電容鼓包等。）高壓板由電源板供電，初步判定高壓包的初級低壓供電電路正常，接下來要區分是高壓包壞還是燈管壞，高壓包輸出外接燈管。
