I'm asking because i have 3 motherboards and 2 video card with blown capacitors,I am trying to decide if it is worth it.

 

The parts are cheap,and the are tons of videos showing how to do it.

why not it's a great homework in electronics

post some pics, replace caps and post some pics back.

 

worst case scenario you'll get some experience in soldering

Do you know how to solder? And are the parts out of warranty? If so go for it, really little to lose.

I have never done it myself,but i do have a soldering iron,and i have watched someone do it and have an idea on how to do it.

 

Yes the parts are way out of warranty,they are old parts,but i had plans for things i wanted to do with them.

I say go for it, best way to learn is by doing, and this seems like a great opportunity.

Give it a try, you have nothing to lose.  Had a Samsung 214T monitor and the screen went black after a few years of use.  Google indicated that this model had a problem with the power board blowing some capacitors.

 

With the help of Youtube, it cost me about $20  (caps, shipping and a solder sucker) and the experience of doing it, I was able to get the monitor working again.

Just be careful and don't go medieval with the soldering iron heat, you could destroy the traces, and if there are traces in the middle of the pcb, good luck with that.

Motherboard and video card pcb's are nothing like the ones in your monitor's power supply.

Motherboards often have traces in the middle of the pcb.

No.

So the parts are dirt cheap, the repair is rather easy and yet you say no? Why? Not bashing here, I just want to know why you think that.

Was just trying to put across the point that the boards are dead anyway, so nothing to lose by trying, and if successful, he got away with a cheap repair instead of buying new boards.....

If the components fails because of the caps. are dryed out, it's worrh a try. But if they "blow up" than the new caps. may also get damaged.

Also MoBo's and GPU's have a lot of layers (>6 usually)and most caps. are connected to GND. So it't extremly difficult to desolder them without proffesional equipment and no experience.

Sure, since the boards are dead anyway, it's worth a try. But don't be dissapointed, if you don't success. You are better off getting familliar with soldering with a more adequate project.

Mineral oil and 40 kg aluminium heat sinks are a perfect combination: 73 cores and a Titan X, Twenty Thousand Leagues Under the Oil

I wouldn't call a board with blown capacitors "dead".
