For those who don't hear any buzzing - do me a favor and try this. Pace off exactly 12 feet in front of the TV, and position your noggin so it is square in the middle of the TV, so you would be able to see your reflection exactly in the middle. Turn the volume all the way off, with the TV on a normal channel, and tell me if you can hear any buzzing. Then move to the side a few feet, and try again. I can't imagine my hearing is all that great, and that my TV is any different than the others. Also let me know if you have a 50" or 58", as that seems to effect it.
