If you have an external audio system connected to your VIZIO TV and you do not hear any sound, you will need to contact the Manufacturer of the device for further assistance.
If you have no audio from the speakers built into your VIZIO TV, HDTV, or HTD, check the following steps:
- Check to make sure the volume level or your TV is set above zero.
- Make sure the TV is not muted.
- Under Audio or Audio Settings in the on-screen menu, ensure the TV Speakers option is set to On.
- Make sure all of the cables physically connected to the TV and the device are securely connected.
- Switch to a different input device and verify there is sound from the TV speakers (for example, a DVD player or a gaming console). Turn the other device on and then use the INPUT button on the remote to switch to that device. Then attempt to play a DVD or game to determine if the TV speakers produce sound. If you do not have another device, and your TV is a VIA Smart TV you can test with any video application.
- If you have a Cable or Satellite box, confirm that the audio is turned up and not muted within that box.
- If there is still no audio after all of the above steps there is an issue with your TV.
