I've had this set since the first week it was released and have been pleased as it's my first surround sound experience.
The only issue I've come by is when I'm watching any kind of video going from a Playstation 3 > receiver > Sony Bravia. About 10 seconds into the video the screen will go black for a couple seconds then come back. It will show the resolution as if it just changed it. It does not matter if it's a DVD, BD, or a video file.
There have also been times where the screen will stop showing any video and will show something like a "snowy picture" like i'm trying to watch an old TV station that's not there. I end up having to turn the receiver on and off to get the picture back.
