VU TV Sound Problem

If the TV powers on but there is no sound,

Volume
Be sure that the volume is up on input devices such as a DVD player or cable box.

Channel
Change the channel to be sure it is not just a problem with that channel.

Headphones
Plug headphones into the headphone jack. If sound comes from the headphones plugged into the headphone jack, this indicates a problem with the TV speakers.

Cables
Make sure your audio cables are correctly attached. See if a new cable works.
