My mother inlaw was having the same problem so I looked into it. I don't watch the channel but I had the same problem on my tv. I finally got a hold of a nice lady at Comcast who spent some time looking into it. She said the it is a network problem which means it was a problem coming from TBN. It is suppose to be being looked at to correct it soon.
