Dell 1800 Issues

[AlanKilian]

Hi. I've got a Del 1800 FP that won't even show a power LED on the front panel.
I read +5.98 and +13.67 out of the power supply. The +13 varies around a lot,
so I'll get a scope on it and see what I can see.

All caps look "non puffy".

My main logic board looks different than the ones people have posted about
in the past, so I'll keep looking around and see what I can find.

Moved from the new member intro thread.

anyway, looks like you have a PSU issue, since there is no 13v rail. there is a 12v rail, so 13.67 is pretty high (unless you meant 12.67).

voltage fluctuations are not so much of an isssue, its the ripple.

caps don't look bloated? what brand? if they say KZJ (or the other bad ucc series, which I can't recall at the moment) on them, then bloated means nothing, as they often dry out w/o bloating.

last uploading some pics of the board and psu guts would be very helpful.
