In other news - what surround sound issues are you having? I was having issues where I wasn't hearing any of the main voices on the screen (only the background/side noises). Upon pulling the radio from the cabinet, it turns out that our center channel speaker cable wasn't hooked up at all.
If it's the same model radio (Genesis 3.0), the outer rim of the cover comes off and shows holes for the screws. There were 6 spots for screws, but we had only 2 screws that were in. When I pulled the radio out - all 6 spots for the screws had been split. Pretty sad sight.
And- a random tidbit. If the speakers are the same. They have a cover that comes off and then it exposes the screws themselves too. I found that out AFTER I pulled the whole speaker from the ceiling.
Anyway, good luck!
