problem with z-560 speakers

Ok my Logitech Z-560 woofer all of the sudden stoped working. The speakers work fine and so does the controller but the woofer gives no bass? I mean if the fuse is gone then well non eof the speakers would work right? Unless woofer has a speciality secondary fuse?

Any ideas would be great since I don't want to scrap this great system.

 

Get a new subwoofer!

 

So there is no fix?

I can't just buy a new one since well They don't sell "just the sub".

Too bad.

 

I assume it is out of warranty? If not then just send it in.
Sometimes it is a cable or connector problem, try to jiggle the connection/cables a little. Try the speakers on another computer just in case it is something on your computer (note if it is an intermittant connection, it may appear to "fix" itself). Try replacing cables if they are not molded in.
If you are hardware tech oriented, you could unplug, disassemble the woofer and look for an internal fuse or breaker (beware of larger capacitors as they can hold a charge for a while after unpluging). It could also have been the victim of a power surge or simply engineered obsolescence or poor manufacturing.
