Oh I thought it was a fuse or the switch. When I called HK and asked them if there were any fusses that could pop, I got resistance and was told to just take to an "authorized" repair shop and if I decided to tear into it, they wouldn't warranty the thing. I actually started pulling screws but was leaving little nicks and figured I'd better not go any further. The video processing on the 7300 is pretty damn cool. Plus, I no longer have that irritating delay when the receiver goes back and forth from analogue to digital. The 7200 will be on Audiogone before long.
