I well recall that our original Pye FV1, installed in 1951 once the Holme Moss transmitter opened, produced a very intense spot when switched off, but I don’t recall any screen burn occurring as a result. It was just an educational reminder of the way that the picture was produced by line and frame scanning. And of course, back in those early days, TV sets would have probably been switched on and off more frequently than today, with a big gap in programme output between children’s programmes around 5 pm and ‘grown up’ programmes not starting until 8 pm.
It may be that as viewers we rather liked the white spot as a response from the set acknowledging that it had been switched off. I find it interesting that our current Samsung QLED simulates frame collapse on switch-off as a similar acknowledgment. It’s enough to cause a sharp intake of breath from any CRT TV technician!
