Sharp LC-37D6U Aquos: Audio keeps going out. Sometimes when I turn the power off, audio comes back.

If you use external speakers or external surround system, check audio connection (RCA cables). If you are connecting external speakers using jack, check jack connector, often this kind of connector give troubles.
Try doing a whack test, hitting (not too hard) the TV sides with the palm of your hand.
If this influence the sound in sense that sound is going and coming back as soon as you hit the TV, that means there is a lose contact to speakers inside TV.
A lose contact to speaker can be an easy fix if you know how to solder.
Try plugging and unplugging headphones, if this affect sound it can be a faulty headphones jack excluding the main audio.
If it is none of the above, then it is a faulty audio pcb, or a faulty control board inside tv.
In this last case you will need to call a technician to fix the TV. Find a repair shop in your area or call the phone number printed on your user manual.

Borrow a surround or use an amplified speakers set and check if you can fix it with this trick.
To
do a real fix, a technician must open the tv, and test all audio
connection, and onboard connection to audio outputs to see what is
wrong.
If TV is going to work with a surround you will probably get
a far better audio quality than the one you get now from TV speakers.
