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.

Is that a serious question, Mikey?
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.

Do I know how to pick careers . . . or what!
seriously?

and when it disappeared would run around the back of the set to try and find it,
Stoopid animal!

do you remember the test card girl? my little bro thought it was me on the TV because she looked like me :-)
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!
Yes seriously. If you use random abbreviations instead of words, you must expect the occasional question !

Thanks Baldric...if capital letters were used, like yours, I wouldn't have asked.
