Question:

How to fix audio sync issues on my TV when connected to an HD cable or satellite box?

Answer:

Determine if the audio is leading or following the picture.

Test different channels to check if the audio is in sync on other channels.

If the audio is in sync on other channels, there might be a broadcasting issue with the original channel or program.

If the audio is not in sync on other channels, try testing additional HD and SD channels.

If the audio is out of sync on all other channels, there could be an equipment or cabling problem.

Cable subscribers: disconnect the incoming cable line from the cable box and connect it directly to the TV; perform an auto program on your TV.

Test five or six channels to check for audio sync issues.

If there's no audio sync issue, your cable box or cables may be defective; try replacing them.

If the issue persists, there could be an issue with your broadcast signal or the TV.

Connect a secondary device (e.g., DVD player, game console) to the input connection you're using for your set-top or satellite box.

Play something on the secondary device and check for audio sync issues.

If the audio is in sync, replace the cables and/or box.

If the issue continues after replacing the cables or box, contact your service provider for further assistance.

If the audio is out of sync when playing the secondary device, your TV needs servicing. Create an online service request to begin the service process.
