I have just hooked up my receiver and all the speakers. Everything works inside, but when I switch to Zone 2 and select input to tuner (to listen to the speakers outside) the whole receiver shuts off. I have tested the speakers and they work fine when hooked into the receiver. When I'm on Zone to and select inputs the receiver stays on when I select everything else (that has nothing connected to it) but when the tuner or Ipod is selected (which has something connected) it just shuts right off. Can anyone help???
