Hmm, quick update... I accidentally turned my 809 off while on the cable box input. Turned it back on... Boom! Audio popping. Unplugged it (forgetting to change it) and... Audio popping again. Changed the input, unplugged it again... No popping! OK! Time to test my theory. Put it back to the cable and turned it off then back on... Audio popping! Unplugged it again still on the cable... Audio popping! Switched the input again and unplugged it. No audio popping! Not having the no video issue when I turned it on Friday, but this is almost confirming what I believed about my Comcast cable box... It's been causing be trouble from the beginning via HDMI. Via component on my DA3ES I never had this, so as I said, I assumed it was my TV... Until over the weekend when I started to suspect Comcast was the evil at work (and when isn't it?!?). Not like they ever upgrade or change their equipment. >.>
So going to have to remember to change away from Comcast before turning it off over the next week or two just to confirm I'm not losing my mind... and then consider how I want to GET ANGRY! at Comcast.
