Question:

How to troubleshoot if your TV is connected to an HD cable or satellite box and experiencing audio sync issues?

Answer:

Determine if the audio is leading or following the picture. Leading means hearing the audio before the lips move. Following means the lips move before hearing the audio.

Test different 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 additional HD and SD channels.

If the audio is consistently out of sync, check if the issue is related to the equipment or cabling.

Cable subscribers: Disconnect the incoming cable line from the cable box and connect it directly to the TV. Run an Auto program on your TV to memorize channels.

Test channels again to check for audio sync issues.

If there's no issue, your cable box or connecting cables might be defective. Consider replacing them.

If the issue persists, contact your service provider for help with the broadcast signal.

Satellite subscribers: Connect a secondary device (e.g., DVD player, game console) to the same input connection as the satellite box. Check if the audio is in or out of sync.

If the audio is in sync, the cabling or satellite box might be defective; consider replacing them. Otherwise, contact your service provider regarding the broadcast signal.

If the audio is out of sync with the secondary device, your TV requires servicing. Create an online service request to start the process.
