Re: I'm stuck - recapped whole board gx620

Thanks for all the input guys im not giving up. Well I am guilty of knocking out contact pad when recapping. What can I do to repair this?

I am sure that the polarities are correct. I've read the gx620 thread and had become aware of the 85c caps, so I make sure my new caps are all 105c. I replace everything, from 2200uf all the way down to 22uf. With ESR tests I find that the 2200uf 820uf and 220uf almost always test high. As for the psu , I keep a working that I use on all the recapped machines just like my RAM and CPU....

I've been recapping a lot of the small Dell GX620s and about a third of them do not POST even after swapping out ALL caps with a mix of brand new rubycon MCZs and Panasonic (not sure on the series). Is there anything else I could be missing? I swap out RAM, CPUs, and nothin.. I guess I was under the impression that replacing the caps were a guaranteed fix heh. Should I just be giving up on these..?

Some background on the PCs: they are on 24/7 eventually they shut off and will not power back on. This is all I really know. When I get them they all have visibly busted caps. Maybe a...

Re: Which of these esr meters do you recommend

+1 for the esr micro Mike is a good man and will come through. I got the older 3.1 which is awesome. Delivery took about 2 weeks batteries included

Re: Dell GX620

Yes I am testing all of the caps out of circuit. Im a bit confused with the multimeter test though. I have a digital one, not sure what setting to use to do the test. There is DCA, DCV, and a section labeled with an ohm sign. In each section are numbers ranging from 200m to 2000.

I tried setting it to 2000 in the ohm section and what the 2200uf capacitor shows are numbers that keep increasing to about 1900 , at that point it stops and goes back to default value of 1.

When doing a DCA test at the 2000u setting i get a 1 or 0 reading on the...
