@@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
