How to Adjust Sync
AV Sync can be adjusted so the audio from the person speaking on the TV matches their lip movement.

Select Settings > SOUND then press WHEEL or ENTER.
2. Select the AV Sync Adjust option and press WHEEL or ENTER.
3. Choose ON if there is a sync issue.
Adjust the External Speaker slider to the left to delay sound, or the right to delay video.
4. If the problem persists, refer to the sections on resolving lip sync issues on external devices.
