Any hope for my speakers?

Well, I've had my Logitech z560's for 4 years now... got them 2001 december back when they first arrived. Now it seems as though the front right channel doesn't output any sound, aka died. It's not the wiring or the satellites, it's the source from the amp, that much I've determined. Figuring for the 2 year limited warranty and the cost of labor nowadays I believe that I don't have any outs in terms of getting company support to help me. Can anyone direct me in terms of if it's possible to fix a problem like this myself, as in open up the back of the sub or whatever and replace little things in there or stuff like that? I'm semi apt technically speaking, but not a pro or anything. Any help would be greatly appreciated.
