Hi DarinBone,
Welcome to the community.
There are a number of circumstances that can cause sync issues:
- If watching a TV program, it could be the broadcast itself or a bad connection between your cable/satellite set-top box (if applicable).
- If a DVD or Blu-ray Disc® player is connected, a poor connection or the disc itself could be the cause.
- When connected to a home theater system with a digital optical cable, then there may be an audio delay that requires a manual adjustment on the home theater system. There may even be a setting on the TV itself causing this issue.
NOTE: Because each of the steps below represents a possible solution to this issue, check if the issue is resolved after completing each step.
- Make sure that the TV has the latest system software (firmware) installed.
NOTES:
- If watching a TV program, try changing the channel to see if the problem occurs on other channels; if it only occurs on one channel, then the issue is with the broadcast.
NOTE: If the issue occurs on one channel only, contact the broadcast network provider.
- Make sure all cables are securely connected to the TV and the source device (set-top box, DVD player, Blu-ray Disc player, home theater system, or game console).
- Try playing a different video source to determine if the issue occurs with other connected devices.
- If your TV has a Game Mode setting, do one of the following:
- Set the Game Mode to Off when watching TV or playing a DVD or Blu-ray Disc.
- Set the Game Mode to On when playing a video game.
- If the issue is happening when using TV speakers, perform a power reset on the TV.
- If there is a home theater system and a digital optical cable is used in the connection, manually change the Audio/Video Sync or Audio Delay setting on the home theater system (if available).
NOTES:
- Audio delay adjustments usually range from 0ms to approximately 250ms.
- For information about the availability of A/V sync or Audio Delay setting, refer to the operating instructions supplied with the product. Go to Manuals, Specifications & Warranty.
- For a third-party home theater system, check the instruction manual or contact the manufacturer for information on how to adjust the A/V sync setting.
If the issue is still unresolved, you may need to contact Sony Support.
