No sound on my hdtv

[Gomedian]

My sound on my Panasonic hdtv was fine then just went out. It's not on mute.

Speakers have most likely blown.

More likely to be a problem with the audio board since most TVs don't have enough power to blow the speakers. You can check with these folks for info and replacement boards.

or you might be able to add a soundbar or speakers to the TV to get sound.
