what exactly are those sparkly noises that come off the tv when u turn it off after it was on for a long time?

Question

yeah

Answer 1

Static electricity.

Answer 2

The picture tube in your television uses a very high voltage to operate it. About 30,000 volts. When you shut-off the the set, the picture tube stores some of this voltage charge which is no longer being used. It needs to go somewhere. The voltage will bleed off through the air and moisture (yes, this will be greater with higher humidity levels) causing the crackling noises. You will probably notice the same thing happens when you first turn the set on. The picture tube needs to equalize the the voltage charge. It is like a large capacitor, similar to a water reservoir, noisy to fill, noisy to empty. Hope this explanation helps!

Answer 3

We call it an "Air Charge" which is nothing more than 30,000 Volts WITHIN the Picture tube charging the surrounding Air near the Picture tube.

This is normal and doesn't affect the operation of the TV itself.

Answer 4

That is static electricity built up in the CRT (cathode ray tube).

Answer 5

i'm 18 and that i'm an A cup too. i think you. i used to be somewhat insecure approximately my boob length while i replaced into in intense college. the lads might consistently tease me saying i'm flat chested. I even used to stuff tissue in my bra to lead them to seem bigger. (how stupid replaced into i?) yet now i do no longer even care. some adult males like ladies with small boobs. huge boobs are not all that. I easily have some pals who've huge boobs and while they'd desire to workout (run) it somewhat gets interior the way. yet another plus for us is that as quickly as we are older, our boobs won't sag that lots :)
