Repair Computer Power Supply /ATX Standby Voltage Fail / Input short circuit
i explained practical How to repair computer ATX switch mode power supply SMPS very easy. this PSU had no output on STBY +5V standby missing, short circuit in input section, the fuse burnt out.
i shared my easiest and perfect troubleshooting techniques to repair computer AT or ATX power supply, i found rectifier diodes, fuse, power transistor, diodes in standby inverter section. smps concept and troubleshooting repairing or understanding repair switching mode power supply basics and working principle. how to troubleshoot input electromagnet induction filter, EMI, bridge rectifier and capacitor. we get 330 VDC at main capacitor. after hat the +330 volts are applied to standby power, which is SMPS and makes +5V SB, these stand by voltage are applied to motherboard which pull down the PS ON green wire to zero level, so the ENABLE OR REMOTE ON or CONTROL pin of #smps will go low that will enable pulse width modulation. and also i discussed smps basics. after watching this video you can capable to:-
