where did the shut off dot go?

[radio nut]

I did have a CBS-Columbia set with a 21yp4 crt that when shut off would go dark instantly......but if you waited for about 10-15 seconds would have what seemed to be lightning on various spots of the crt on and off for another 20 seconds.
It was kinda like watching a thunderstorm!
I sold the set to a CBS-Columbia collector who had all their sets but the one I owned.
I still kick myself for not getting video of it!

My Motorola 9VT1 does this. After I switch it off, if the room is completely dark, occasional flashes can be seen on the screen. This goes on for several minutes while the voltages discharge. Interestingly enough, my little 2" Broksonic TV/radio combo has a dot that appears on the screen for a fraction of a second at switch off. It is very unusual to see a solid state battery portable do this.
