I have a used Logitech z-680 pc speaker system.  It's been great for the one year that I have owned it so far but today 3 of the 5 speakers just stopped working in the middle of some music I had playing.


The sub itself works fine and the center speaker as well as the right front, but the back left, back right just stopped working.  


I didn't have it on that loud (volume was around 35% on the unit but 100% on my PC).  I think I read somewhere that some people said the PC volume should only be 80% and was wondering if the 100% PC volume setting could have damaged the sub/amp where the wiring for the speakers is connected?


The actual speakers themselves work because I tested them in the center speaker plugs and sound came through the speakers but they don't produce sound when plugged into their respective slots.  So I think something in the sub/amp unit is wrong.   


Is there a way to fix it, or replace a part (ie. a fuse?) in the sub/amp unit if I open it up?
