My whole family and I thought we were going crazy when we first started noticing the audio wasn't synced with the video. We originally thought it was the cable hook-up, and the cable service came out twice to replace the box. The sync was STILL off! So finally we came to the conclusion that it was our beautiful new TV. The picture is fantastic, but sadly the non-synced audio and video can drive one insane. After reading tons of negative reviews on various websites, we were relieved to know we were not alone.We're exchanging it at the store later today for something different.
