Thanks for the responses - I'm trying to find a schematic of where the fuses are as I am a bit of a novice on popping open the hood on these devices.
One other note- zone 2 works just fine. I've heard that sometimes these receivers get 'stuck' thinking headphones are plugged in when they are not, but I can't see that there is any indicator on the display saying the receiver thinks headphones are plugged in (there may not be any indicator, period). I have tried compressed air, and need to track down a 1/4 inch adaptor to see if it's anything physical that could get jarred by plugging in/out.
