Mfg: Vizio
Model: VX42L HDTV 10A
Mfg Date: Aug 2007
100 ~ 240Vac at 50/60Hz

Problem is simple and hopefully the fix is too. Everything on the TV works except the audio. Have picture, have remote functionality but no audio.

No, it's note on Mute.
Yes, the volume is up.
Yes, the speakers are turned on in the TV's menu.
Have tried an input that I know works and have no sound.
The Audio Out does not work either.


What could be the problem?
What's the solution?!

Have you tried resetting by unplugging the unit, waiting a little while, and plugging the unit back in Question

Yes, have tried resetting that way. I have also opened it up and hit the "reset" button on the main board.

Sounds like you need a main board then. It does the audio processing.
