Question:

 How to troubleshoot audio sync issues on a TV connected to a cable outlet or antenna?

Answer:

Determine if the audio is leading or following the picture.

Test other channels.

If audio is in sync on other channels, contact your service provider.

If audio is out of sync on other channels, test different types of channels.

Check if audio is consistently leading or following.

Adjust millisecond delay time in home theater/stereo settings (refer to user manual).

Test TV speakers for audio sync.

If using digital audio out, connect it to the digital audio input on your home theater/stereo system.

Check for faulty wiring or excessively long audio cable runs; consider reducing length or using specialized wire.

If audio sync issue persists after trying all these steps, your TV requires servicing. Create an online service request.
