what do you call the little high-pitched noise you hear when the TV is on?

Question

I don't really know how to describe it, but it's weird. I can hear it even in the TV's all the way down and I'm in the next room. It's sort of like the noise the TV makes when you first turn it on but quieter.

OK another detail: it's not so much a "noise" as it is a...frequency. It's not like one long beep or anything. It's like a radiation (I know that's not the right word but whatever) that the TV gives off.

Answer 1

Interesting question: it's called "flyback transformer whine". In a tube television, the flyback transformer is used to drive the energy to the electron beam that paints the signal on the screen. It oscillates at a frequency of around 15,000 cycles per second, and sometimes vibrations can be heard or sensed at this frequency.

There's no good way to fix it without an expensive service call, but as HTDVs and flat panel technologies replace standard tube TVs, this noise will become a thing of the past.

The good news is, if this sound bothers you, it means your hearing is very good and/or your are still young and healthy. Many people, particularly anyone with even minor hearing damage and most people over a certain age cannot hear this high of a frequency at all.
