I am going to call Sony Tech Support but I was wondering if anyone else experienced this issue with their Sony here. My old one, which was a 52", never gave me this problem. It's pretty weird...some channels it's fine and others the video is lagging behind the audio by around a half second, other times the lag is between 10 and 100ms. And if I switch to another channel and switch back it's back to being in sync again. WTH?
