As per a suggestion on another post, I contacted Thor and Customer Care emailed me all the production drawings for my coach. I probably printed over 30 pages and there were several pages dedicated to the TV's and HDMI switch box wiring.
I will make another run at it in a couple weeks. If I still have issues I will have one of my 10 or 12 year old grandsons stop by and figure it out!
