I am attempting to trouble this supply wo schematic. The 5 volt supply shuts down when I put a small load on it. I have relaced a few caps that did not pass esr tests.
This is a multi-output supply. It is used in HP laserjet iip/iiip. There is on IC on the input side, SI-9509 that I have no specs on. I am not sure how the feeback works into this IC.
Thanks for any suggestions.
