天浦正達20多年專注工業觸摸屏維修、工控機維修、人機界面一體機維修,主修維修品牌有:貝加萊、AB、ASEM、研華、西門子、施耐德、普(pu)洛菲(fei)斯、三(san)菱、倍福(fu)、ABB、力士樂、控創(chuang)、海泰克、研祥、三(san)洋(yang)、邦(bang)普(pu)、步科、歐姆龍等品牌觸摸(mo)屏(ping)維修(xiu).
ASEM觸(chu)摸屏(ping)維修,機器故障:因上電黑屏(ping)來修
該機器也是直流24V供電的,首先用萬用表測了24V電源輸入端與地之間阻值,2兆多歐姆,不短路,然后(hou)打(da)開(kai)機器后(hou)殼,測電(dian)(dian)源(yuan)(yuan)保(bao) 險絲,完好(hao).于(yu)是給機器上24V直(zhi)流電(dian)(dian),電(dian)(dian)源(yuan)(yuan)指示燈亮,初步判(pan)定電(dian)(dian)源(yuan)(yuan)電(dian)(dian)路正常(chang).用手電(dian)(dian)簡照屏,能(neng)看到屏上的(de)畫面(mian)內容,說明(ming)了信號驅(qu)動板(ban)已經(jing)工作并且正常(chang)輸出了信號.屏顯芯片(pian)也初步判(pan)定正常(chang).
到(dao)此,這種情況就(jiu)(jiu)看是(shi)(shi)燈(deng)管(guan)還(huan)是(shi)(shi)高壓(ya)(ya)(ya)(ya)的(de)問(wen)題了.(高壓(ya)(ya)(ya)(ya)板壞掉就(jiu)(jiu)是(shi)(shi)一整塊黑板,不(bu)(bu)會有任(ren)何變化.大多高壓(ya)(ya)(ya)(ya)板損(sun)壞,是(shi)(shi)會出現一亮就(jiu)(jiu)滅(mie)的(de)故(gu)障的(de)"如:12V供電(dian)處的(de)主電(dian)容鼓包等.)高壓(ya)(ya)(ya)(ya)板由(you)電(dian)源板供電(dian),測U31 1501-33 3A的(de) DC/DC降壓(ya)(ya)(ya)(ya)芯片(pian)輸(shu)出腳(jiao)正(zheng)(zheng)常(chang),又測U32 1501-50 3A的(de)5V DC/DC降壓(ya)(ya)(ya)(ya)芯片(pian)輸(shu)出腳(jiao)正(zheng)(zheng)常(chang)測高壓(ya)(ya)(ya)(ya)包輸(shu)入電(dian)路的(de)各管(guan)件及元件正(zheng)(zheng)常(chang).初步(bu)判定高壓(ya)(ya)(ya)(ya)包的(de)初級低(di)壓(ya)(ya)(ya)(ya)供電(dian)電(dian)路正(zheng)(zheng)常(chang),接(jie)下來要區分是(shi)(shi)高壓(ya)(ya)(ya)(ya)包壞還(huan)是(shi)(shi)燈(deng)管(guan)壞,高壓(ya)(ya)(ya)(ya)包輸(shu)出外(wai)接(jie)燈(deng)管(guan).亮的(de)話就(jiu)(jiu)是(shi)(shi)屏的(de)燈(deng)管(guan)問(wen)題,不(bu)(bu)亮就(jiu)(jiu)是(shi)(shi)高壓(ya)(ya)(ya)(ya)包的(de)問(wen)題.
故用手頭上的燈管測試儀,直接使用燈管測試儀,斷開顯示器的(de)電源,測(ce)試(shi)儀(yi)(yi)通電,把(ba)燈(deng)(deng)(deng)管(guan)(guan)于高壓板的(de)連(lian)(lian)接線斷開后,連(lian)(lian)接到測(ce)試(shi)儀(yi)(yi)上(shang)(shang),測(ce)試(shi)儀(yi)(yi)上(shang)(shang)電燈(deng)(deng)(deng)管(guan)(guan)不亮.說明燈(deng)(deng)(deng)管(guan)(guan)已壞(huai)(huai).為了(le)準確和(he)穩妥,又取好的(de)燈(deng)(deng)(deng)管(guan)(guan)來連(lian)(lian)接到機器(qi)的(de)高壓輸(shu)出端,上(shang)(shang)電燈(deng)(deng)(deng)管(guan)(guan)正常(chang)點亮,由(you)(you)些確定確實是屏(ping)里面的(de)燈(deng)(deng)(deng)管(guan)(guan)壞(huai)(huai)了(le),該機器(qi)上(shang)(shang)所(suo)用的(de)屏(ping)燈(deng)(deng)(deng)管(guan)(guan)是L型的(de),由(you)(you)于手(shou)頭有現成的(de)屏(ping),故(gu)直接給客(ke)戶更(geng)換了(le)一個新屏(ping).給整(zheng)機上(shang)(shang)電測(ce)試(shi),故(gu)障消失(shi),屏(ping)顯畫面正常(chang)了(le),機器(qi)修復(fu).后對壞(huai)(huai)屏(ping)的(de)燈(deng)(deng)(deng)管(guan)(guan)進行更(geng)換后,壞(huai)(huai)屏(ping)也(ye)修復(fu)好了(le).
