Thanks Pro. I'm not an electrician, but I'll ask sparky to check that the system is grounded properly.I would not feel comfortable checking out the electrical panel. I somehow though can't picture him going..." Oh my Gawwd (we're in FLA remember), I knew I forgot something!" Your right though. A bad ground could affect the whole system.
It was a new receiver. Changed a Z1 to a Z11. The one in the bedroom is a V-3800, so I guess the price I mentioned before should have been $1600 instead of $2500.
I long for a better world. One in which a chickens motives will not be questioned when mearly crossing the road.
