3V,5V對地短路維修方向1.目檢:Chipset(Southbridge,Northbridge,I/Ochip,GD75232,Soundchip),AC97,PWM...是否有燒毀,USB,P/S2Connector,PCIslot,AGPslot,ISAslot,CNRSlot,Chipset…是否有撞壞造成短路.2.觸摸:打開電源觸摸Chipset是否有發燙.3.電源不打開時,用電表檢測那組電源短路,再決定移除短路電源有連接相關晶片,PWM,電阻電容..4.Mainchip南北橋,I/OChip,Soundchip,AC97,PWM…都移除短路沒解開,建議換板..注意:3V&5V短路維修方法Chipset移除至短路解開再焊,不能移除一顆換上顆,有可能換上新Chipset因短路電源沒解開,Turnonpowerchipsetbruntout.
