Few days before my smps was remaining on even after I had shutdown the windows. 2 days before suddenly the system went off on its own. And now the problem is when I try to swith on, the processor fan rotates for a second even the smps fan does the same work and then goes off.
I Completely isolated the smps from ******board and tried to turn it on by shorting the green wire with a com. wire but the still the same picture. then i cleaned the smps pcb for any dried glue remainings and the dust contaminents. Suddenly Yesterday night smps fan remained on without any other load on the psu. I thought it solved my problem. So I connected it back to the MB and made all the connections as usual. System remained on and prpperly working for around 5 min and then suddenly went off as it went of previously. Now the ******board led stays on, also the cpu fan rotates for a secnd & goes off. Green wire showing me 4.5v but the none of the other wires have supply.Kindly tell me as exectly which section of smps is giving me the problem. Its alredy out of warranty so now I can go for self repair.
there are no blown components. And one of the filter capacitor(Ac)side 330uF,200v when I connect tester to the top metal portion it shos current in it. What is the problem???
Thanks!
