Everything was working just fine yesterday, then I go to use the stereo today to play some xbox and notice the controller wouldn't change the sources. If I turn off the receiver and put it on the source I want it to be on it will work, but if I try to change sources via the dial on the receiver it will show no signal once I change the source and there will still be no signal if I turn it back to the original working source. Also once I change sources and it shows no signal, nothing else works either. Can't change the volume via the remote or dial. If you guys could help me figure this out I would be greatly appreciative.
