kennethk Posted January 7, 2014 Posted January 7, 2014 A friend said that a couple of his caps are abuot to blow and I have 0 -none experience replacing them. I kno whow to spot damaged ones and know I'd just have to find someone willing to solder them but are all caps the same? Keep in mind this is a very old pc I think maybe 2004ish. I just need to know what caps to buy. Share this post Link to post Share on other sites More sharing options...
Stonerboy779 Posted January 7, 2014 Posted January 7, 2014 Maybe its time for him to move on and upgrade and without knowing what the specs of the caps are there are no recommendations that can be made. Then you must also think what other damage was caused when they blew and what caused them to blow. I Dont really believe its worth fixing but if a full upgrade isn't wanted then just look for replacement boards etc Share this post Link to post Share on other sites More sharing options...

Stonerboy779 Posted January 7, 2014 Posted January 7, 2014 Then look for replacement parts unless you can get the dimensions and markings of all the capacitors. You will also need to be able to differentiate between electrolytic, film, ceramic caps and so on. I still believe you'd have a better time getting a $10-20 board (if its the mobo that's gone as I suspect) off of ebay. You've already stated you're not confident enough to properly identify and replace them so save yourself the hassle. But as far as replacements go, so long as they come out rated the same with the same tolerances and are replaced in the same polarity it should work regardless of brand. 1 Share this post Link to post Share on other sites More sharing options...

I was scrolling down to type that more or less. I've replaced caps on boards before and unless it's a newer board it's not worth it and then it's usually under warranty anyway. If it's from 04 find someone like me that holds on to way too much crap and get them to sell you a replacement part cheap. Or browse around craigslist for $75 PCs and talk them down to $50 and do it that way. Lots of options really. Share this post Link to post Share on other sites More sharing options...
ohldboy Posted January 7, 2014 Posted January 7, 2014 (edited) Go to BadCaps. Lots of knowledge and discussion. To replace Caps you need a decent solder station, some skill, know the type of solder used, then use the proper caps. If you can find a recent dead motherboard, you should be able to use the caps. Use Japanese caps if possible. What is his motherboard and CPU? DDR RAM? 3BTech may have something. If it is AMD difficult. SOCKET 775 3Btech has a refurbished 945 board for $26 BUT it is DDR2.

SpikeSoprano Posted January 7, 2014 Posted January 7, 2014 Replacing caps arn't a big deal if you are familiar with a solder gun, read all the specs and colour codes off the caps and get same ones, also you are better off replacing even the caps that look good because like the bad ones they will swell or leak soon. Then he will have to get or buy a decent solder gun and eletric solder, remove the mb and have great patience and good vision. So,,, in the end it would have been cheaper to buy a good used mb, and if he can't stop buying booze for a week to save up for this he has bigger problems than his pc not working. jmho !

Master Binky Posted January 7, 2014 Posted January 7, 2014 (edited) It's only two solder points, but like they have said already a good soldering iron & tip are a must unless you can make up for it with skill (at which point you'd have the proper tools...). The ones I've seen go bad are typically surrounded and a pain to work on which is why you don't want to half ass it on the tools. Since you say they are about to pop I am going to assume they're electrolytic capacitors. With that in mind, make sure you make note of the polarity of the one you are removing and the one you replace it with. As long as you replace it with the same voltage & farad rated capacitor (and the same type which I Edited January 7, 2014 by Master Binky Share this post Link to post Share on other sites More sharing options...
kennethk Posted January 7, 2014 Posted January 7, 2014 Hopefully I can track down a board whenever he decides to drop it off. Share this post Link to post Share on other sites More sharing options...
Hyper Threaded Posted January 8, 2014 Posted January 8, 2014 Trying to revive a ten-year old PC isn't worth it. Find one at a thrift store that will fit his needs. Share this post Link to post Share on other sites More sharing options...
kennethk Posted January 13, 2014 Posted January 13, 2014 Well I took a look at the motherboard and there were about 4 caps all corroded I told him he can get a used motherboard on ebay for about $20 so lets see what happens. Much faster then having to resolder everything. Share this post Link to post Share on other sites More sharing options...
