Thank you for posting your question on Just Answer! I will be happy to help you with this problem. Can you please give us some more information so I can better answer your questions.
-Do any of the buttons on the tv itself work? (menu, vol, chan, ect.)
-How old is the unit?
- Do you have this problem while watching all different devices hooked to this television? (DVD player, cable, satellite, game counsel, ect.)
Please give me this information and I will be happy to assist you further.
What about the buttons that are physically on the tv, have you tried those?
If all the buttons are working on the tv itself, but the volume still wont move then I would say the main board in the set has failed, this is actually quite a let down because the repair is going to run more than the set is worth. An average main board replacement on a set this size is about $350 which is about the price of a new set.
The only last ditch effort I could give out is this:
Turn the set on
While it is on unplug it from the wall
Let it sit 10 minutes
Plug it back in and try again
I am not very hopeful for this, but once in awhile it does solve the problem.
If you would like any additional information or have more questions please don't hesitate to ask!

I am sorry if I did not give you the information you were looking for, I guess I don't understand what you were looking for? I do know your television and have repaired them many times but I don't see any other answer other then the one I gave.
Is there certain information you are looking for?
Also as I have said, please do not accept an answer unless you are 100% satisfied.
