I can hear whether they were on or off, and whether they were tuned to a signal or not.
A video signal synchronized up has a very distinct profile, and people who can hear about 15 khz can hear the sync signals modulating the higher frequency component.
I could at one point, adjust horizontal and vertical hold to a stable signal eyes closed.
Some sets were very loud, and I could hear them rooms away. Walking The Halls in my primary school, I could walk by the classrooms and say they have a TV on oh, and nail it a hundred percent every time.

At least within the house - we moved around a lot, but I lived in a few three storey stonework houses, and could generally tell from 'the other end' of the house if the TV was on.
I don't recall hearing the same noise from fridges though!

It only works with CRT TVs though. It's a 15khz tone, due to magnetostriction in the flyback transformer: https://en.wikipedia.org/wiki/Flyback_transformer
I have never encountered someone else that was able to hear whether a tv was on or not. At what distance could you do that?
