Answer to: The sound on my TV stopped working.I couldn't fix my sound either on 55" Vizio So I purchased a fiber optic cable 12$ and a inexpensive sound bar speaker with blue tooth $62 total In less then 2 minutes I had sound. There will be a red light on the back of your tv when powered on. Plug in fiber optic cable in back of tv and into sound bar, plug in sound bar to 110 outlet .turn on sound bar Put Sound bar On setting that reads digital optical. A sound was on. You have to control volume with a different remote But: A lot better than $6-800 for new tv.
