Been reading the posts here for a month or so. Have had the TV now for 2 weeks and haven't seen this discussed. I have a sound/picture sync issue. The sound is ahead of the picture on all my channels. Thought it was my provider, dish, but I don't have that issue with any other of my TVs in the house. Any suggestions? Dish reciever feeds a Denon reciever, which then goes directly to the TV. Prior to the Sharp I had a 58" panasonic with the same setup, and didn't have this problem.
