Hi. Greetings from Argentina.
I'm having trouble with this PSU that was given to me. Previous owner discarded it without repair attempt.
I'm very new to PSU repair but have knowledge in electronics.
The PSU only has +5vsb and does not turn on when PS_ON is grounded.
I've checked every major capacitor with a capmeter, but I have no means to measure ESR. All caps measured good. Their brand is ANODIA.
PSU has 3 NPN Power Transistors that are good and 3 diodes at the output that are good.
All other diodes in the board measured good. All resistors measured good too.
I'm starting to think that maybe the PWM chip is dead, but as I have no experience with PSUs I'm in doubt.
PWM chip is "2012 GND202" and googling I've found this PSU is made by Solytech.
I'm lost!!. Any help would be greately appreciated.
Sorry for my english.
