I am having and issue with my AVR-1909. I have a Scientific Atlanta 8300hD, a Sony S350 Blu Ray Player, and a HTPC attached to it via HDMI. I have few issues:
1) Sometimes the picture and audio goes out, I get a black screen with no audio
2) Sometimes there's a snowy screen, but audio is fine.
3) Sometimes the screen flickers and the the audio/video goes in and out.
It wasn't bad before, but now I it's unwatchable. It is very frustrating. Is this a handshake issue?
