See my thread in the Plasma and LCD section. I really do not know what is going on, but I appreciate your post and know it is not my set. Sounds like Comcast tinkering!!!
Interesting. When I first found the HD channels back in December, they were on 89-1 through about 94-4. Then, one day about a month ago, all of a sudden those channels quit working, and after I rescanned they were at 231-240, where they had been ever since until the glitch last night.
When the 231-240 channels disappeared last night, I couldn't find them anywhere else. Admittedly, I may have missed them though. Since I unplugged and then rescanned they've been back at 231-240.
I agree, it's probly Comcast's recent tinkering that confused the TVs' tuners.
