When my sister and I were younger, we would always run up to the TV when it was being switched off to watch the little white dot disappear into nothingness (okay, we didn't have a lot of money, so had to make our own amusement).
My question is this...whatever happened to it?
Why don't modern TV pictures fade to a little white dot anymore?
Pictures were displayed by deflecting a variable intensity electron beam across and down the phosphor coating inside the glass. When power was removed the deflection circuits shut down before the voltage that drew the beam forward had discharged producing a spot near the centre until the heated cathode creating the beam had cooled.
I started fixing TVs about the time it became cheaper to buy a new set. Then I went into piano tuning. Now you can buy a new keyboard for about the same price as a tuning.
The Cat we had at the time used to try and get the dot'
and when it disappeared would run around the back of the set to try and find it,
Stoopid animal!

If our little TV conked out, my Dad would tell us it was clogged up with dead cowboys and Indians, he watched a lot of westerns. Please don't lecture me on non-pc terms!
