Thanks for the reply. Unfortunately, the problem you're having indicates that the audio IC that drives the internal speakers has failed. It is common in these sets as they use very low powered amplifier IC's that generally heat up and fail. The IC is located on the mainboard, and requires the board be replaced. This type of repair is typically around $275 to replace the Mainboard. I wish I had better news, but there are no resets or buttons you can press to fix this problem and the set will require service.
