Lip sync is the combination of the two signal carrier frequencies being out of sync
one signal carries sound and the other the picture and they normally come together correctly but that can be upset by a blip in the power supply, problems in the signal from the station or atmospheric disturbance
try changing channels a few times , try shutting the set down and then restarting it
read the operators manual for any clues in the trouble shooting section
Lastly talk with a repair shop for any advice on how to fix
Vizio HDTV- Lips out of sync
Anyone with a new Vizio E601i-A3 60" or 70" HDTV that is
having audio "Lips out of sync problems" with a cable or satellite box.
On Comcast cable boxes (or others), here's what you need to
do: FIND MENU for AUDIO or HDMI setup on
CABLE BOX or Satellite Box.
FOR COMCAST
1. Turn on TV and have Cable box Turned OFF.
2. Press MENU on COMCAST REMOTE.
3. Go to AUDIO Setting OR HDMI Setting. (On cable or Sat.
BOX)
4. Change setting from Auto to L-PCM. (Turn off cable box to
exit)
This should resolve any "out of sync" lips to picture after
commercials on HD channels.
*This is a handshaking issue from the cable box to the Vizio
