Thank you so much! There are few things that bug me as much as having the sound go out on my TV. Plus when you have a bunch of little kids at your home TV repair can be stressful. I didn't think of changing the resolution. If it happens again I'll see if that helps.

Turning off the Dolby digital worked for me but now the quality of the sound is awful! Why would it work for so long before and now stop working?
