how old is your plasma TV? try check the switch / volume of the sound settings.. Sometimes, when you always increase the volume, it will tend to alter the limit of sound and causing the sound to provide sound undesiredness. I suggest to check it with a liscensed technician.

The TV was made by LG. You should be able to google an LG distributor or try ebay. The 953 is readily available but the 917 may be hard to find. Won't be cheap for new ones, around $350-$400 for both unless you can find used.

Thank you for the help. I actually changed the whole main power supply board and it still did not fix the problem. When I put the new one in, I had the tv on for about 3 hours and then I shut it off. No sooner did I get it back up on the wall and the problem started all over again.When I pulled the original board, the caps all looked fine so I am not even sure the board is bad. Problem is there is no one around me to test it. I am not going back to the same shop that already told me that it was a bad main power supply board. Any other suggestions?

Most likely the TV has a Mother board related issue. Your TV is just like a computer. When it freezes up, nothing responds and you have to pull the plug to turn it off.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part or replace the whole circuit board. The Service Manual will give you circuit diagrams, test points, and part# lists.Service manual cost about under $20. Most cases the new part cost less than $15. New circiut board, depending on type, may cost about $125.
I hope I shed some light on the subject for you.
