well i've been hearing loud popping noises in my office, well turns out they were coming from my video card. 9 of the 10 caps blew before it stopped working. can i buy new ones and solder them in? where would i get something like that? they are marked "FZ6A 1500 6.3V" and "FZ6A 470 16v" thanks ~Adam
Who actually made the card? That's a pretty catastrophic failure, I want to be sure never to buy from them.
A DIY fix is the first thing I'd do. Replacing them isn't very hard. You'll find some caps here: Capacitors | AllElectronics.com
I dunno. It may have just been cheap electrolytic caps on a low-end cheap card, so it blew because of a bad batch of electrolyte, combined with passage of time.
it was an eVGA 7600GT, it took some time, i've heard one or two of them blow, the card is about 18 months old. It was not overclocked, just a secondary card to run my monitors. I will check out that website and order some new ones, i've soldered a whole bunch before so it shouldn't be too hard
can anyone point me in the right direction as to which caps to buy based on those numbers, is the 1500 microfarads?
Caps will blow if you reverse the voltage or overload them (duh). Does your video card have the 6 pin power connecter on it because im guessing maybe a spike from the power supply may have caused the caps to blow.
Power spike would be my guess. TI used to ramrod the caps on thier older versions of VC II's (sat system video cipher 2's)...the ones everyone wanted to be able to black box them. It was like they had a self distruct feature built in. We recieved three cases of new revision VC II modules and the next day we started getting an ass load of service calls to go out and replace VC II's. For two weeks, that is all I did...pull the back cover, pull out the VC II push in another one.....spend 20 minutes on the phone authorizing programing, rinse repeat. all the ones I replaced had the same blown caps. Mind you, we recieved the replacement parts one day before they started blowing. We couldn't even figure out why we recieved the parts until three service calls into the blowout.
My camera sucks, but you can kind of see it, there is one that didn't blow. I'm still working on getting a new camera... ~Adam
Correct me if im wrong, but arn't those solid state caps? I've never seen any of those type blow before nor have I ever replaced any like that. May have been a short somewhere on the video card because I can't see all of those caps being defective.
I've got the same issue on two 7600GT video cards, two caps on one card and five on the other. I don't think the cards are worth fixing but wont know until I price replacement caps. They are company cards so just thought I might try to fix them instead of replace them since I don't need high end cards. Purchased them in March of 07, built two identical systems in June of 07 and now both are bad. No overclocking and good power supplies so I think they are just bad quality cards. If you start to do some Internet searches I find more folks have the same issues with the same cards.
