My panny has had this issue since new, and I was too dumb not to return it immediately: On digital tv broadcasts, whenever the screen goes black with very little white (like during the closing producers credit of a CSI show) and the background music fades out, the audio becomes garbled - sort of a motor-boat sound. I always notice it at the end of most tv shows, but also occasionally when there's low-volume music and a mostly black screen. I've wasted hours with customer service trying to explain this, but they've never heard of this before. There have been no firmware upgrades for this model, either. I think it's a vocoder issue, but has anyone else ever heard of this phenomena? Audio under any other condtion is just fine. :confused:

The Flat Panel Plasma section would be the best place to ask for help. Good luck with your problem.
