I aquired the TV today. It was working in a home theatre system when I picked it up. I brought it home put a converter box and an antenna on it and the picture is great but I cannot get any sound. The mute is not on . The on screen volumn is turned up but no sound. I did not see any options on the menu to help. Is there a set up to change from a home theatre system to a stand alone tv? Any ideas will be appreciated. Thanks
