I tried to trace it-- don't know what I'm looking at.

Everything I can see looks connected. if it's an issue on the roof, no-can-do-- 3 stories up and I'm afraid of heights!
They are sending th enew box anyway. I guess I'll hook it up. If the problem keeps up, I guess I'll have to lose a day of work for a service call. Bummer.
As for the 6 tuners, I emailed CEO@echostar and explained my situation (large house, extended family). They were very good about it.
