I'm not sure about your symptoms, but when I read HDMI weirdness/issues and Integra together, I think uh-oh, time for a new processor! Unless you can get ahold of the HDMI board for your model and manage to replace it yourself...
Integra had big failure numbers with HDMI.
My 9.8 HDMI board fried and the unit began running hotter than normal. It's a brick now...
I just got an certified reconditioned, closed box 80.2, w/ upgraded HDMI board, on eBay, but it showed up with no remote. The seller is supposedly getting me one...
Anyway, good luck, but I suspect more 'weirdness' will hit, then it dies... I hope not for you though.
