I just encountered this problem last night: I have a Bell HD-PVR connected to my 919 via HDMI (also a Sony S360 BD player via HDMI which seems to be fine). The HDMI out is connected to a Sony 52W3000 TV. The problem is that the audio from the PVR is fine but the video keeps "winking" out every 2 seconds.
I did a quick search on this thread but did not see anything similar.
So far, I've tried the following, with no results:
1. Changed out HDMI cables
2. Connected PVR to another HDMI in
3. Manual reset of PVR and AVR
4. Left components unplugged overnight
5. Kuro link set to off
I did connect the PVR direct to the TV (via HDMI) and it works fine. Also, if I connect the PVR via optical for audio and component for video, the winking stops, but the picture and sound are not as good as with HDMI.
If any of you have encountered this and found a solution, I'd appreciate a response.
I've only had the AVR since December 3, 2009.
And, yes, I'll be contacting Pioneer later today.
Thanks very much.
