6AV6644-0AB01-2AX0維修[故障分析處理]

首先檢查各接線接口是否出現松動，然后檢查串口及中斷號是否有沖突，若有沖突，應調整資源，避開沖突。再檢查觸摸屏表面是否出現裂縫，如有裂縫應及時更換。還需要檢查觸摸屏表面是否有塵垢，若有，用軟布進行清除。觀察檢查控制盒上的指示燈是否工作正常，正常時，指示燈為綠色，并且閃爍。
如果上面的部分均正常，可用替換法檢查觸摸屏，先替換控制盒，再替換觸摸屏，最后替換主機。
如果是表面聲波觸摸屏可進行如下檢修：
可能是(shi)(shi)觸摸(mo)屏的連(lian)(lian)線(xian)中(zhong),其中(zhong)一個連(lian)(lian)接(jie)主(zhu)機鍵盤(pan)的連(lian)(lian)線(xian)(從鍵盤(pan)取(qu)5伏觸摸(mo)屏工作電壓)沒有(you)(you)連(lian)(lian)接(jie),請檢(jian)查(cha)連(lian)(lian)線(xian)。可能是(shi)(shi)觸摸(mo)屏的驅動程序(xu)安(an)裝(zhuang)(zhuang)(zhuang)過(guo)程中(zhong)所選擇的串口(kou)(kou)號和觸摸(mo)屏實際連(lian)(lian)接(jie)的的串口(kou)(kou)號沒有(you)(you)對應(ying)起來,請卸載(zai)驅動重新安(an)裝(zhuang)(zhuang)(zhuang)。可能是(shi)(shi)主(zhu)機為國產原裝(zhuang)(zhuang)(zhuang)機,所裝(zhuang)(zhuang)(zhuang)的操作系統(tong)為OEM版(ban)本,被廠家(jia)調整過(guo),造(zao)成串口(kou)(kou)通訊(xun)的非(fei)標準性,與(yu)觸摸(mo)屏驅動不兼容,如(ru)果(guo)可行 請格式化硬(ying)盤(pan),安(an)裝(zhuang)(zhuang)(zhuang)系統(tong)后(hou)(hou)驅動觸摸(mo)屏。主(zhu)機中(zhong)是(shi)(shi)否(fou)有(you)(you)設備與(yu)串口(kou)(kou)資源(yuan)沖突檢(jian)查(cha)各硬(ying)件(jian)設備并調整.例(li)如(ru)某(mou)些網(wang)卡安(an)裝(zhuang)(zhuang)(zhuang)后(hou)(hou)默認的IRQ為3,與(yu)COM2的IRQ沖突,此時應(ying)將網(wang)卡的IRQ改用空閑未用的IRQ。
