About the only simple things are:

If headphone jacks they can cause it.

If speakers in set are switched to OFF>

If there is sound when a DVD is connected to a rear audio/video input the audio out circuit in the set is GOOD and something in the settings etc is wrong.

failing all this the set may have a audio circuit problem---time for a tech or a shop to listen.

SOURCE: TV does not respond to

When this kind of a problem appears it is usually due to a malfunctioning microprocessor IC . The IC cannot be replaced and the board has to be replaced as a whole. Replacement board should run you about 100$. I can find you a replacement if you are interested in fixing it.

Are you using a cable box or a satelitte reciever? If so i would suspect them first. If not, unplug the TV for 2 minutes and try again.
