Another video card with Sacon FZ

[c_hegge]

It's a Galaxy GeForce 7950 AGP video card. Two of the caps are bloated. both are 470uF 16v. There are some other FZ which look OK, but I'll relace them too. 3 other 470uF 16v, 2 16v 220uF and 5 6.3v 1500uF. I'll post some pics later. I'll probably use Rubycon MBZ or somthing similar to replace them.

Here are the pics. The customer said he was using the computer and heard it go BANG. he thought it was the PSU, until he found these.

Re-capped it (finally). I replaced the 3 larger 470uF 16V with Sanyo SEPC Polys and everything else with Rubycon MBZ. It works good enough to get into windows but I haven't tested it beyond that.

Well done!
... Time to start looking on ebay (or similar places) to get one like that on the cheap .

NNNNNNNNNNNNNOOOOOOOOOOOOOOOOOOOOO!

I accidentally bumped the card while it was running. Now it's fried (won't even POST).

I have a non-working PC with a bad video card, a Club3D GF6600LE with Purple Sacon FZ (with K vents, not fake-poly).
I wonder how many different looks of these FZ caps exist.

Re: Another video card with Sacon FZ

boatloads. they are on mobos too.

fz are special as they are hands down the most violent exploders. they go off like a firecracker, guts are spewed everywhere, nasty to clean up.

... As I found when I held these FZ caps over a candle. All but one went bang. I can't find the cans for some of them.

How did you bump it? Did it crack or knock something off?
Could still be repairable.

Interesting. I thought they only came in black and blue. Thanks for the heads up, I'll now definitely keep my eyes open for anything with purple polys as well.

Re: Another video card with Sacon FZ

From the way he wrote that post...I get the impression that he shorted something.

However that is speculation.

Re: Another video card with Sacon FZ

It was just a small bump, nothing knocked off, shorted, etc. I suspect it may have caused an arc in the AGP slot (a bit like if I had tried to hot-swap the card). It's definately dead. I tried it in another motherboard and it didn't work there either.

Re: Another video card with Sacon FZ

Bunch of SMD transistors and FET's. Get checking.

Are you getting any voltages on the caps or open cap spaces?

[c_hegge]

Re: Another video card with Sacon FZ

My DMM died, so I have no idea whether or not the caps are getting any voltage. I'll try re-soldering the joints, although I doubt if that will fix it.

Re: Another video card with Sacon FZ

Re-soldering makes no difference (as I thought).

[Toasty]

Re: Another video card with Sacon FZ

Wasn't implying a cold joint. Meant that you could (simply) be looking at a bad transistor/diode/FET that may prove an easy fix. DMM problems aside, if the voltages are missing, that would be where I would start looking.

Hopefully the GPU is ok.

Re: Another video card with Sacon FZ

I realised that you weren't suggesting a bad joint, just thought I would try it anyway. I'll have to get a new DMM before I can test for missing voltages.
