Hi, all. Thanks so much! Awesome example of message boards working. I was trying to fix it from 2000 miles away as I am traveling and my wife was frustrated that the remote did nothing - turns out our 12-year old has been sleeping in my bed and, though he is a whiz at most devices, he somehow managed to open a C4 menu by mistake and changed the room to one that is blank/not programmed. Switched it back over Facetime and we're good to go. Thanks to all who responded!
Turns out, the screen actually read "Master Bathroom," which is not programmed (maybe it's a preset?), so when she selected Watch TV, the "Empty" messaged popped up - I guess, telling us the Master Bathroom has not been programmed, so it is empty.
Thanks again!
