This reminds me of a weird phenomenon in my parents living room: Our Samsung TV would stutter and colors would distort when lighting the candles with a lighter (one of those long-neck trigger models). Never figured out why but I suspect an EM pulse was created with each trigger "click", which affected the cable signal.
