Today my rear channel started buzzing real badly. I changed it to
another speaker to make sure it wasn't the speaker. I got the buzz off
another speaker, so I know the channel is bad. Is that something I
should try to get fixed or would it be cheaper to buy a new one. It's
a JVC 8000 VBK, which has all I need, DTS, Dolby Digital, plenty of
inputs...

Did you change the wiring? Some of your connections might have become
shorted or corroded.
