Only a m5160 other than what I've wrote to the military why would a amp play on both yet not just one both channels work just not at the same time simultaneously.. bull shit

I've had two Onkyo receivers in the past. Strange things happened with them such
as FM not working, one or the other channel would go out. In each case
I put the receiver on a shelf and bought another. The first time it happened
I had replaced the Onkyo with a newer Onkyo. After a while the new Onkyo
flaked out and I bought a Denon. Then for some reason I connected the
original Onkyo up and everything worked. After a while I tried the same
thing with the second Onkyo and it also worked. My conclusion is that
if you unplug the Onkyo and leave to so for several days it heals
itself.

YMMV

Since you're replying to a NINE-YEAR-OLD posting,
I'd bet the OP's problem is now solved.
