Hi All,
I am trying to repair O2 power supply "SONY-APS 90".
when i power on, fan turns on for few secs and and turns off. I swapped all Transistors and Daughter PCB with OK power supply but condition is same. Transformers seems ok. Output side capacitors are ok(checked out of circuit). Please advice further. does any one has its Schematic, pls. let us know.
Regards.
