西門子PCU50老款工控機黑屏故障診斷方法：840D數控系統機床，的PCU50.3重新啟動時，計算機不能正常啟動，上電后數碼管顯示88 ，兩燈同時顯示紅色
故障分析：PCU無法啟動故障，說明內部調用時出現了問題。
故障排除方法：
1.重新啟動試機；
2．檢查外圍接口線路是否有松動或接觸不良；
3.檢查供電單元，正常輸入電壓是+24vdc；
4.打開PCU50.3單元，將PCU 后蓋打開，檢查內存條是否插牢靠，扁平電纜插接是否可靠； 
5.如果仍未檢查出故障，檢查西門子840D 的軟件系統HMI advanced，可以將以前備份好的系統備份重新鏡像到一個新的硬盤上做實驗。
6.后可(ke)以判斷PCU50.3的(de)主板損壞，此時需要廠家或專業維(wei)修(xiu)公司(si)進行(xing)維(wei)修(xiu)。
