I'm actually thinking this might be it as well.  I played more after I
posted this last night and I did have someone mucking in the panel where
the cable comes into the house, and there is a power booster there.
It's possible it got unplugged.  However, I wasn't able to check this as
there was someone sleeping on the couch in that room at the time.  I'm
hoping that this is it though.
