I just purchased the receiver from Goodwill. It powers on and all the buttons and dials seem to be operational based on the graphic display. I have a cd player hooked up and my Athena speakers/subs connected to the Front L/R speaker posts. There is no sound from the CD player or the tuner. The speaker button is not turned off. I tried a factory reset procedure to no avail, the only thing that did was reset it to the demo mode - aargh. I should say that I don't have the remote for this unit, which may make it impossible to access many menu features. I really only want to use the receiver for playing music. I don't believe it's in protect mode because I do hear the amp click on after startup. Any input is appreciated.
