I just bought a friend's old Onkyo receiver for my sound system. I can get the front and center channels to work fine, but I can't get anything from the rear. I know that the receiver worked fine when I picked it up at my friend's house. I know it's hard/impossible to troubleshoot this from the information I have provided, but any input would be appreciated.

I don't know much about this kind of stuff, but Im pretty confident all the physical connections are right.
