Someone reported this exact problem in this thread or the F7100 thread, and it has nothing to do with the Harmony. Someone else responded with the answer, but, unfortunately, I can't remember it. I think it had something to do with STB being in a list somewhere in the TV that needed to be enabled or disabled. Try searching the two threads and make sure to use the key word STB.
