Default Re: Why did folk always unplug the telly at night?

Rediffusion Mk 3 and early Mk 4s has this feature, which as everyone knows caused the button to fly across the room - we kept a few buttons in stock. Early ITT CVC25/32 chassis had the solenoid switch as well though without the projectile tendencies. They did give a satisfying 'clunk' though. I think I still have a blue switch for one of these.
Nowadays TVs are never switched off so this sort of thing would be pointless - imagine having to get up to turn the set on!
Have you noticed in films when a TV is turned off there is a high-pitched 'whoop' noise? Probably from the same school of thought that computers all bleep when an important screen is displayed.
