Our channel 11 has been misbehaving. Sometimes there’s a line of static near the top of the screen. And sometimes the sound on whatever we’re watching is a few seconds behind the picture, much like a badly dubbed kung fu movie. It’s not happening on any of our other channels. We’ve tried rebooting the system and the problem still came back. I’m thinking its something with the channel’s programming. Have you ever had anything like this happen to you with only one channel? What did you do?
