Can you help me fix it?

[MartinvdDikkenberg]

Recently I bought a secondhand gpu only to findout that it is quite damaged. (see photo's) Do you have tips to help me repair this cart, uf it is still possible?

Damaged parts c4036, c927, c245, c926, c248,c7339, c613,c918,c4021,c4042.

it gives a vram error

Sounds like they are all capacitors. It's possible up to an extend if you are really good are soldering at the board level repair, as usually this is done by machines when assembling the cards. You'll know if its not possible if there is actually a hole going through the PCB as there are layers on theses PCBs (like motherboards) and those traces are no longer connected.

There is no hole in the pcb (maybe under the copper? spatter) so it should be possible, but I have never soldered so it's going to be hard. But even if I could I have no replacements for the capacisors. Do you know where i can get them?

Then you might be in luck. Personally, I've never done this type of thing before and would only recommend searching around and taking it to a repair shop (although they might refuse to do so for legal reasons). Maybe there are websites that sell small electronics?

if you end up doing this i recommend to practice soldering for a day , on another ｐｃｂ , because while it's not hard, it does require some  practice,  you'll also need desoldering material and likely flux cleaner + brush...

 

 

And these  small capacitors are kinda  delicate, a good soldering station and thin solder is recommend (i guess 0.5 mm)

there are , but unfortunately i don't recall names as i never bought anything like this either, at my work we just get those in big boxes mostly from china, and yes, finding the right parts seems to be the most complicated thing in this situation...

are the codes on the board the codes for the type of capacitor? or is there a universal type of capacitor?

I've only watched videos from Louis Rossmann (repairing MacBook Pros) and those codes can be for the manufacturers on identifying what the components are linked to; their purpose.

I would implore you to find a crappy board from something that doesn't matter to practice on. That way you at least get some exposure to taking things off of the board, cleaning it, and soldering back to it. Remember, flux is king. Maybe find something like a tv remote to get started. That way you can easily make sure it works after messing with it. You also may want to get a soldering station that has a magnifying glass, or maybe a microscope, to easily contend with soldering  small parts.

The Caps you are looking at are surface mount (soldered to contact pads on top of the board), and you should be able to match them relatively easily. All you have to do is get ones with the same capacitance in the same general shape. The problem I have found when doing similar stuff is that it is hard to buy just one of them. Typically there is a minimum order of like a hundred to a thousand depending on where you get them.

[OrangeSunshine]

I would also like to point out that there is a reason these caps are blown in the first place. It is possible that whatever blew 'em up damaged other components on the board, so you may go through the trouble of finding the caps and find out that the card still doesn't work.

i read this online a lot, not sure why, i have  soldered thousands of these small caps and similar, I've not ever used  flux, as far i know its in the solder we use already, but what is really  important is to clean the pcb properly with pcb cleaner and possibly remove old, excess solder .oh and definitely need a pair of esd safe tweezers!

I think that I can beter try get a 'new' one, because al the tools I need will cost me more than that it wil save me

i mean none of this is really expensive, and you could probably get by with a really cheap soldering iron, but i agree it does add up ......

It probably wouldn't cost too much, but the time investment may be a little annoying. I just thought of another possible route. If you could find a dead card that is the same model, you could probably get it real cheap and use it as a donor board. That would give you practice working with the same components you need to replace. All you would have to do is check the caps with a multimeter  when you remove them.

I think I'll try usingorangesunshine tip, and figure out how soldering works.
