I have to make this quick right now as we have to head out for a while. Can a legacy quad take out a tuner (one tuner) on a 721 or vice versa?
I have one of 4 leads coming into the house with no signal. I don't know at this point if it's the cable itself or the quad. By utilizing two known good leads, I get "Locked - Wrong Sat" on Tuner 1, 110 T16.
It looks like the 721 has problems. It seems quite the coincidence the receiver and the quad (one port) failed at the same time.
