hate to sound like an idiot but i just switched over from the 970 to the 990 and i am having difficulty setting it up. i made all the connections as i had with my 970 turned everything on it defaulted to the tuner i was able to select cd and was able to get sound from my cd player. but when i hit menu on the remote or on the front panel i am not getting input config and cant make any adjustments. any ideas out there??
