Stereo Reciever Help

[Tornado]

I have a Pioneer SX-1100, and I've been having problems with it. The left and right sound channels randomly cut out, and only by switching the input selected can it be brought back usually. It also occasionally blanks out both channels and goes totally silent. I'm not sure what the problem with the reciever is. I originally thought it wqas the speakers (the wires on them were incredibly poor), so I rewired the speakers, and that helped but it still does it. Any suggestions? If the thing is toast I'm gonna end up purchasing a Mitsubishi DA-R25, so its not that big of a deal, but I would like to know if it can be repaired.

Bringing it back by switching makes it sound like dirt or corroded contacts, and not necessarily an electronics problem. That can be cleaned pretty easily I would think.
