TV Soundbar Sync Problems

[nh65230]

I have purchased a TV KD-49XD8305 and a soundbar CT790WBW. I have had to sync the sound between the two twice now. It  increased the sync setting from 0 to 50ms, which brought the sound and tv back into sync.This lasted about a week, when i had to re sync again, this time returning back to zero. Any idea's.

Did you try rebooting teh tv (off button pressed till the poweroff message appears on screen)? It solve most of "random" problems....
