That's what I'm leaning towards it's trouble with the dish box. Sorry to repeat myself but I just don't understand why other video sources work, zappiti ,bluray player. I could eliminate the balun to the master by a long hdmi cable but unable to the eliminate the balun that connects the outdoor theater. Outdoor theater works fine which is primarily used for the movies. Really don't watch much TV outdoors. But on rare occasions in the fall I like to watch football out there. I will try your suggestion and thank you so much for your replies.
