Greetings
I recently bought kfa2 gtx 470 gc graphic card 'in great working condition' but when it arrived, I saw that 6-8 capacitors are missing from the back side of the card. Can someone help me identify these parts, or does someone have a service manual for that model?
 
better to post a picture so people can see what you asking aswell.

Here are photos from the back side with marked places of missing capacitors, some of them aren't properly on their place but I think that the card isn't 'baked'

does the card work? its actually possible it looks like that from the factory for some crazy reason.

No, bios marks gpu failure at startup and freezes. There are visible signs that there were capacitors mounted on these places.

Rma it is another option since surface mounted capacitor is kinda hard to replaced and theres no guarantee it would work on this card

This. Kind of a no brainer really. People can't sell things without providing an option of return within 30 days at least (otherwise illegal). Unless it was a private cash in hand job, in which case, GG, ask for pics BEFORE you buy.
 
See, this is why I never wanted to buy used hardwares. Just send it back, mate. Don't wait, don't think, just send it back. And get a refund while you're at it.

ps. not all used hardwares are bad, but next time please be very careful before buying used hardwares.

the seller lied about the condition of the card. he had 'quotation' marks in there.

it means it used to be great before he drop it somewhere and now he wanna sell it
 
Open a case with paypal then if its shot.

Yeah, he lied and he changed his phone number, he gave me some other adress, not his. Unfortunately I can't do anything about it because I don't know his real adress, he sent me via post express here in serbia and I paid it with cash when it arrived so that's it. I can only hope that it may be fixed one day or it will go for parts
 
He doesnt say where he bought it used. So depending on this would determine your next


To bad, that sucks

Yes, I know that. I get burden many times by mostly USA residents. Recently with someone from Arkansas, Fort Smith.
Anyone who live around like to pay a visit? :)

As for the card, I think it is possible to save it, but it will require some work. The most important are the missing small caps near the PCIE port. The later bigger missing caps are for voltage filtering, so, they are important, but not that much for post.
The way to fix is easy - take a TWO 40W soldering irons, heat nearby on the similar PCIE line cap from both sides and desolder it (pick it off the PCB like a Chinasee person picking up food).

When you have done that, then measure what capacity it is and then go and buy same ones and solder them all back. Problem solved.

Sounds quite simple, right? But you need the equipment, of course. And good source of SMD caps... also. The ones near the PCIE port are enough to be 6.3 or 10V (beware of strong voltage bias on ceramic caps, typically at rated voltage, the capacity is -60%...!!! so not to worry overshoot the voltage - typical PCIE voltage is 1.2 to 1.8V - near these low voltages are the DC voltage bias typicaly minimal) but these bigger one(s) are probably 16V ones, as they seems to filter the input of the Voltage regulator, not the output.
For perfact safety I recommend measure first on the card when working the actuall voltages.

Hope that helps! Hi to Serbia! Hope USA is not ready for another round of "humanitary bombing", as these warcrimes are called there by even our president Vaclav Havel. (and instead of getting shot for treason, he was hailed as hero by the media, so... go figure...)

i ever saw someone using glue to attach surface mounted capacitor

It'll be hard to get the SM parts for that to put back on (not to mention the solder paste although you could use flux and lead free solder wire to put them on there) and get it working. It is very doable seeing as the pads look in tact. If you could find the parts (and use the Internet to search for the correct ones based on pictures and a manual) you could put them back on (paying special attention to polarity) and possibly be good to go.
Reality is that is a headache and a half so you could see if you can contact the manufacturer and get it repaired that way. Good luck bud. Ticks me off you got done that way.

Thanks mate, I have a friend who is working with mobile phones, so he has all the equipment and these caps, necessary to fix this card if possible
 
Sounds good. Let us know, how it went. Definitively I will NOT recomend to glue these components back, you NEED to solder them back. Soldering small components (typicaly 0805 caps - that is 2mm long and 1.25mm in the width) is hard, very hard, but it can be done. I prove it recently with my FX 5600 XT mod as nice experiement if this is possible. And what result it give (huge):

Tough luck mates, the card is dead and gone, gonna sell it for parts. Anyway, thanks everyone for help!
 
sorry to hear that
so you wanna buy another graphic card to replace it?
