I had my Tivo connected to HDMI IN3 and once in a while the picture would become mostly pink. This appears to be related to HDMI handshaking, since the picture would start out normal when I switched to HDMI IN3, but then after selecting a recording to watch, the picture would disappear for a few seconds and then it would be mostly pink when the picture came back. Usually I could fix this by switching to a different HDMI input and then back to IN3. This pink problem never happened during the year or two that I had the Tivo connected to my older Onkyo TX-SR805.
I just switched the Tivo to HDMI IN6 and so far it seems fine, though this problem is intermittent, so I will have to monitor it for a while.
On the one hand, if this fixes the problem, I should be happy. On the other hand, it would suggest there is a problem with HDMI IN3. I still have about a week before my 30 days are up at Amazon. I hate to go through the hassle of returning the 809, but I would also hate it if this was a symptom of potential additional problems down the line.
Can anyone offer any advice?
