I got the TV used. Right when I got it home it worked fine. A couple of days later, it stopped making audio. It doesn't matter whether it is set for an antenna, or any of the vidoe sources, it won't make audio. The video is fine. I have tried a couple of different video devices in all of th einputs but nothing works. I have gone through every section of the mnue and the remote control but can't get it to make a sound. Is there some sort of internal speaker setting or something?

There could be two reasons for not getting any audio.
Firstly. the speakers got disconnected. That you would know better if the TV was subjected to shocks/ thuds etc. Otherwise go to
Secondly. The Audio IC/module is busted. To confirm this, please remove the back cover and take a peep inside. Can you find some bulged or burst capacitors. Capacitor is a round cylindrical thing that keeps jutting out the printed circuit board (pcb). If found then these have to be desoldered and then replaced by exactly the same specification ones. If you cant see any then maybe a professional help would be more appropriate. If the audio module was not out then there would have been some sound some where as you have tried all possible methods of getting audio.
