When it is turn on first time in the day, it works for few hours without problems. Then it will turn off the video only, audio still working fine. I turn it off for one minute, turn it on and it works again only for maybe 20 to 30 minutes and the problem shows again.
Sounds like sustain board issue

I have a question? Do you move your Television frequently, OR do you unplug it frequently when it's not in use? I have found that doing either or both of those things can bring on problems, especially audio problems.
I've had the disappearing sound problem twice with my Element FLX-2610. This latest time I was stumped because the full scan didn't resolve the problem. And of course, the sparse manual that comes with the TV contains no troubleshooting advice at all.
But I did find a suggestion on another sveral other sites: Reset the TV. You might have a small reset button (like you would find on a DSL modem) somewhere on your TV but there is a manual way to do it two. Whichever way you do, MAKE SURE to disconnect every single device (yep, it's a pain) and UNPLUG the TV before doing this.
To reset with a reset button, disconnect devices and unplug the TV. Depress the reset button for 5 seconds. Reconnect devices, then plug in the TV.
Manual Procedure:
Disconnect all devices
Unplug the Television
Using the on/off button on the Television (NOT on the remote), depress and hold the button for 5 seconds.
Reconnect the devices, then plug in the TV.
Unless something has shorted out or burned up inside, this resetting, as a last resort, should fix the audio problem. Worked like a charm for me!
Good Luck!

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on. If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

I had the exact same problem and I fixed my Westinghouse 32 inch by replacing the power supply. You can purchase it at
