觸摸(mo)屏(ping)(ping)加(jia)電(dian)(dian)后顯示(shi)屏(ping)(ping)沒有顯示(shi)故障(zhang)(觸摸(mo)屏(ping)(ping)維(wei)修業界俗稱為黑屏(ping)(ping)故障(zhang))給施耐德XBTGT5330觸摸(mo)屏(ping)(ping)電(dian)(dian)源(yuan)供(gong)電(dian)(dian)端加(jia)上(shang)+24V的(de)電(dian)(dian)源(yuan)后，觸摸(mo)屏(ping)(ping)上(shang)的(de)運(yun)行指示(shi)燈指示(shi)綠色，隨后變(bian)為橙色，但顯示(shi)屏(ping)(ping)不會(hui)顯示(shi)

觸摸(mo)屏(ping)維修(xiu)思(si)路(lu)(lu)分(fen)析(xi)。觸摸(mo)屏(ping)顯示(shi)屏(ping)上的(de)(de)運行指示(shi)燈可以由綠(lv)色(se)轉為橙色(se)，但屏(ping)幕不能正常顯示(shi)，說明觸摸(mo)屏(ping)內部電(dian)源(yuan)電(dian)路(lu)(lu)已經工(gong)作。根據觸摸(mo)屏(ping)上電(dian)后的(de)(de)故(gu)(gu)障(zhang)現(xian)象，將(jiang)觸摸(mo)屏(ping)維修(xiu)思(si)路(lu)(lu)及故(gu)(gu)障(zhang)部位分(fen)析(xi)列舉(ju)如下：1.液晶顯示(shi)屏(ping)本身出現(xian)故(gu)(gu)障(zhang)而(er)導致；2.高(gao)壓板出現(xian)故(gu)(gu)障(zhang)不能供給燈管點亮(liang)及工(gong)作電(dian)壓而(er)導致的(de)(de)黑屏(ping)；3.燈管燒壞而(er)導致；4.主控制板出現(xian)故(gu)(gu)障(zhang)而(er)導致的(de)(de)黑屏(ping)；5.開關電(dian)源(yuan)不正常導致的(de)(de)黑屏(ping)。

觸摸(mo)屏維(wei)(wei)修(xiu)方法和步(bu)驟。針對觸摸(mo)屏維(wei)(wei)修(xiu)思路(lu)分析出引發故障的部位(wei)，維(wei)(wei)修(xiu)工程(cheng)師結(jie)合觸摸(mo)屏工作原理(li)按照先易后難的維(wei)(wei)修(xiu)步(bu)驟，進行了(le)以(yi)下檢查：

上(shang)電(dian)(dian)(dian)后用萬用表(biao)的(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)檔檢(jian)測(ce)電(dian)(dian)(dian)源板(ban)各支(zhi)路輸出(chu)的(de)供電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)，檢(jian)測(ce)結(jie)果+5VDC電(dian)(dian)(dian)壓(ya)(ya)(ya)、±15VDC電(dian)(dian)(dian)壓(ya)(ya)(ya)、+24VDC電(dian)(dian)(dian)壓(ya)(ya)(ya)均正(zheng)(zheng)常(chang)，說明開關(guan)電(dian)(dian)(dian)源部(bu)分正(zheng)(zheng)常(chang)，排出(chu)了開關(guan)電(dian)(dian)(dian)源存在問(wen)題的(de)可(ke)能。

用(yong)高壓(ya)(ya)(ya)檢測儀檢測高壓(ya)(ya)(ya)板輸給燈管的(de)工作電(dian)壓(ya)(ya)(ya)，結(jie)(jie)果(guo)顯(xian)示只(zhi)有(you)(you)幾(ji)伏的(de)電(dian)壓(ya)(ya)(ya)，說(shuo)明引(yin)起(qi)觸摸屏黑屏的(de)故障(zhang)(zhang)原因是由于高壓(ya)(ya)(ya)板出(chu)故障(zhang)(zhang)引(yin)起(qi)的(de)。檢查高壓(ya)(ya)(ya)輸出(chu)板中相關的(de)電(dian)路，結(jie)(jie)果(guo)發現有(you)(you)一只(zhi)場(chang)效應晶體(ti)管（2SD3125)的(de)漏極(ji)與源極(ji)擊穿，一只(zhi)1Ω的(de)貼片電(dian)阻燒斷。

更(geng)換上(shang)好(hao)的(de)2SD3125場效應晶體管、同規格(ge)的(de)電阻后，裝好(hao)高壓(ya)板，重新(xin)給觸(chu)摸屏(ping)電源供電端(duan)加上(shang)+24V的(de)電源后，觸(chu)摸屏(ping)出(chu)現了(le)光柵，顯示出(chu)了(le)正常的(de)畫(hua)面。
