西門子IPC677啟動無反應黑屏十年修復診斷:通電后CPU風扇和換氣風扇都正常,測量電壓也正常,但屏幕無任何反應,鏈接外接VGA也無顯示,由此證明主板有故障了,利用測試卡檢測,PCI時鐘有,復位也有,但不跑BIOS代碼。
維修流程:當PCI時(shi)(shi)鐘(zhong)和(he)(he)復(fu)(fu)(fu)位(wei)都有(you)的(de)情況下,就只有(you)北(bei)橋(qiao)(qiao)和(he)(he)CPU的(de)復(fu)(fu)(fu)位(wei)和(he)(he)時(shi)(shi)鐘(zhong)這幾個地方(fang)出(chu)問(wen)題(ti)才會導致主板不工(gong)(gong)作,更換(huan)CPU后(hou)(hou)故障依舊,那剩下了北(bei)橋(qiao)(qiao)和(he)(he)北(bei)橋(qiao)(qiao)的(de)時(shi)(shi)鐘(zhong)還有(you)復(fu)(fu)(fu)位(wei)、CPU的(de)時(shi)(shi)鐘(zhong)和(he)(he)復(fu)(fu)(fu)位(wei)這5個部分。繼續排除后(hou)(hou),CPU時(shi)(shi)鐘(zhong)正(zheng)(zheng)常(chang),但(dan)沒(mei)復(fu)(fu)(fu)位(wei)信號(hao),復(fu)(fu)(fu)位(wei)信號(hao)來自北(bei)橋(qiao)(qiao),另(ling)外CPU供電(dian)也不對,只有(you)1.55V,正(zheng)(zheng)常(chang)時(shi)(shi)1.75v左右,CPU供電(dian)決(jue)定于(yu)是否復(fu)(fu)(fu)位(wei),沒(mei)復(fu)(fu)(fu)位(wei)也不能(neng)得到(dao)正(zheng)(zheng)常(chang)的(de)電(dian)壓(ya)(ya)。根據以上(shang)的(de)思路(lu),北(bei)橋(qiao)(qiao)損壞可能(neng)性很大,很多現象都反應到(dao)北(bei)橋(qiao)(qiao)沒(mei)有(you)工(gong)(gong)作,北(bei)橋(qiao)(qiao)芯片(pian)(pian)組(zu)為VT8606即(ji)PN133T,更換(huan)北(bei)橋(qiao)(qiao)芯片(pian)(pian)后(hou)(hou),CPU復(fu)(fu)(fu)位(wei)電(dian)壓(ya)(ya)正(zheng)(zheng)常(chang),時(shi)(shi)鐘(zhong)也正(zheng)(zheng)常(chang),但(dan)電(dian)壓(ya)(ya)還是偏低,CPU工(gong)(gong)作電(dian)壓(ya)(ya)根據核心(xin)來確定的(de),信號(hao)給電(dian)源管(guan)理芯片(pian)(pian)后(hou)(hou)輸出(chu)額定的(de)電(dian)壓(ya)(ya),使其正(zheng)(zheng)常(chang)運(yun)行,檢測后(hou)(hou)管(guan)理芯片(pian)(pian)有(you)問(wen)題(ti),更換(huan)后(hou)(hou)空載1.34v屬(shu)于(yu)正(zheng)(zheng)常(chang)電(dian)壓(ya)(ya),裝上(shang)CPU后(hou)(hou)升至1.75v,主板開始跑BIOS代碼,電(dian)腦正(zheng)(zheng)常(chang)運(yun)行,維修完畢。
