When I change from a standard def channel to a HD channel, the picture will drop and after about 6 seconds the receiver simply says "No Signal." I turn the cable box off and back on and it reacquires the signal. Both have been annoying, but I've lived with the issues for 8 months. I finally caved and took my receiver to an Onkyo service provider where it is right now. Unfortunately, they have been unable to duplicate the problem so far so they may not be able to fix it and I'll be stuck with these issues. Oh well, these pale in comparison to the problems I've been having with my Samsung BD C6500 blu ray player, also at the shop. At least the sound of the 9100 is so sweet it makes up for any minor inconveniences with the HDMI board.
Do they use a similar board in the 9300? I know its not the same since the 9300 is 1.4a compliant. With my old system I had the same issues with what you describe( coupled with an expired warranty), which is why I bought the 9300 in the first place...along with the fact that I wanted to trade up to 7.1 when I bought my panny 3dtv.
Sounds like a possible short to be honest caused by overheating, which a tech who checks for five minutes wouldn't find.
I'd check to make sure your equipment is ventilated, as cable boxes are notorious for overheating.
