Re: Oddest Behavior.

Worked on this some more today. Determined the main problem is a blown mosfet on the APFC circuit. Obviously smoked and I missed it during my visual. Hate that. Also, it tests good from the Peak Tester. Even though half the writing burned off. The interesting thing momaka said came up When I tried to put one of the caps back in there was one leg that just would not play so I had to clean the crap out of it and it's still kinda sketchy.

I did find the caps were not charging before with the light bulb trick but they are now. 150v on both which...

There is definitely some bad soldering inside this thing. Not terrible but I see some obviously cold joints on the thicker wires.

Hi folks. Working on a Corsair PSU. I am semi new at SMPS but I have around 1500 pro hours working on 230/400 in the combat zone and some lesser amount on the side with 120/220 state side. I also have about 8000 hours pro time as a bench tech. So I feel like I know how to do this kind of work safely. I have been reading up on SMPS prints and watching video's for about 1.5 years now. Worked on one already which I had to change about 10 components. Cheap POS amplifier.

Anyways....Back to the weirdo Corsair issue. Fuse was blown when I got it. Did the light bulb trick and it stays...
