Here's what happened to me, with x10 signals.  I put in 2 new LED mini
flood bulbs in my range hood.  When they were on, all x10 stuff didn't
work.  I returned them and bought different ones ... same results.
Later, I purchased 2 similar ones (still different mfg) at Lowe's and
they didn't affect x10 at all.  So, the problem could be something as
simple as changing a light bulb.
