I'm going to America in two weeks time but I don't suppose I'll see any CRT TV set's as they'll have all gone to TV heaven by now...
There might still be some in hotel rooms fed by an analogue distribution system.
The TV in our Orlando hotel was an old analog LCD, when I went into the menu it was working on NTSC & was set to cable channels, some channels were very bad quality with hum bars. I clicked over to OTA & had a manual search & found a snowy picture on channel 6 low band, think I read somewhere that some low power community analog stations are still running, wondering if it was one of those I was picking up?
Had a bit of excitement one day: There was a bright flash of lightning, a loud crack, & a tree across the road from our hotel disintegrated in a cloud of smoke, there were broken off branches & leaves everywhere, I nearly needed a change of underwear, some kids & adults were screaming. The electricity stayed on though & the poor struck tree was near the overhead power lines that supplied our hotel.... Had a good time & didn't want to come home...
