I'm experiencing something similar. Hooked up my new MacBook Pro to the "game" hdmi port. That worked fine, but when I disconnected and switched to sat/catv, the receiver started acting funny. The picture would display intermittently and the sound would drop out. The unit's display would indicate that it suddenly detected a Dolby B signal. No menu would come up. Finally I performed a factory reset by holding in the power button for 5 seconds. It almost immediately said "cleared", though the instructions say this should take up to 5 minutes. The "Easy Setup" screen now shows, but none of the settings show properly. All I see is a mixture of dots and blocks. Have tried the factory setup a few more times, but does not help. Would like to update the software, but without a functioning menu this does not seem possible. I'm pretty much stuck.
