testing Dyna Comp PSU 614-0028

[mloret]

Hey guys. I just recapped a dyna comp PSU. I tried to test it on my LCII and it didnt do anything. No power to computer. I assume that this thing is compatible with my LC. Previously I had recapped a TDK and this one didn't give me any trouble. Anyone ever work on the Dyna Comp model and experience this? I'm sure I did something stupid, but not quite sure what.

Also the "pads" on the soldering side were unlike anything I had ever worked on. Maybe I soldered to this incorrectly? Any help is appreciated.

Here are some photos.

I see some corrosion damage on the underside of the board. You should check for continuity between all supposedly connected solder pads.

Thank you for the reply. Where do you see corrosion damage on the underside? I am not questioning your observation, I just want a better idea of what I am looking for.

Thanks again.

On the left side (probably for AC) and bottom middle there appears to be some corrosion and/or old solder in need of a reflow.

On the photo you posted it's the clearer green spots on the AC side as Byrd mentioned. However sometimes traces are cut in ways that are not apparent at all to the naked eye, so it would be a good idea to check everything just in case.
