i explained practical How to repair computer ATX switch mode power supply SMPS very easy. this PSU is using SDC2921 IC which is PWM and intelligent power supply monitor. i shared my easiest and perfect troubleshooting techniques practical troubleshooting. 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:-

You are welcome!

@@HaseebElectronics Dear friend many thanks for your reply.Your explanation is very clear.My professional is electrical (not electronic or machatronic).In my higher education I had to learn basic electronics.But I am not involved with electronics.So its very easy to understand your explanation.
I am having my used computer power supply.it won't work.Earlier it work and it shows some error.When power is on it won't work but if I touch top of the unit then start.I found some places got heated up look like transistor (3 pin unit) near small transfomers.I re-solder the loose connections.After that it work few months.Yesterday again it won't work and I found fuse had blown.When I was check it I found two diods in rectified unit has out of order.Then I replace them and check.The line and neutral shows 5 ohms.earth is o.k.Then I connect it to the to the 230v power supply. Again fuse has blown.What may be the reason?

[@HaseebElectronics]

​@@aluthgederawimalasena8825 after replacing the diodes, if it gives 5 ohms, it means the input resistance is very low, in this case it have to burnout the fuse. may be still there is some remaining short circuit, which is to be removed.
check main dc capacitors, might be short circuit, check diode polarity
check input yellow X2 capacitor

[@aluthgederawimalasena8825]

@@HaseebElectronics O.K. I will check thanks.

[@mylifetips2496]

Wow

[@hichamtassi1753]

If the PWM has power but not switching, how to find which line has a short ? how many ohms between the yellow and black wire are considered normal ? can we put 12v from other source at the barrier rectifier and test the current at the exit to find the short ?
