Flux capacitors, not fluxing(where can I get new) - Page 2

Technically, I'm with Geo on this one. Don't think you can replace these and get up and running like new. Something most likely made them pop, and then while they were on their way out they most likely [pun]"incapacitated"[/pun] other board components that were depending on their properties of capacitance.

But:

But if you're gonna be tossing it in the trash for a new one anyways, why not try?

Those other components should be fine... a busted capacitor does not build up any charge, so it can't send any current down the line.

The problem is the caps themselves. They are corroded inside which causes them to bulge and short out or in some cases loose continuity. On a mother board they seldom cause additional damage unless the electrolyte gets on other components. They are easy to replace on two ply boards, but can be difficult on four and six ply boards. Most desktop boards are two ply. This is the number one RMA problem for the industry at the moment.

I wasn't saying that a bad cap would cause other components to go bad. I wasn't aware that there was an actual known problem with bad caps on PC motherboards. I'm still a little skeptical on that despite all the flashy websites. But if people have had success replacing them who am I to argue? Admitedly I have no experience with component level repair on computer motherboards as it was never considered cost efficent at any of the places I worked, even back when motherboards were expensive. I am quite familier with blown capacitors from my olden days working on tv's and radios. But there when a cap was blown, it wasn't because the cap went bad, it was because something else went bad and caused the cap to blow.

Those can caps are quite easy to blow actually. You will find that out if you try to replace them and put them in backwards.
