congratulations you are one of the few who can hear the 15.735 Khz whine of the horizontal deflection. As others have said, its right on the edge of human hearing.

The flyback transformer in a CRT makes a high-pitched whine that is on the edge of the range of human hearing. Typically, what you'll find is that many younger people can hear it, but many grown adults cannot due to typical gradual hearing loss.

Vacuum tubes? The final television offered that had a vacuum tube in it replaced into around 1975. those that mentioned heating and cooling have been relatively maximum suitable. i've got been to many properties for this grievance and admittedly there's no fix. the undertaking is that those new gadgets are distinctly lots made completly of plastic. If this could be a rear projection DLP or liquid crystal show then the popping is the cabinent itself. whether that's a plasma then that's back the cabinent and the panel itself doing an analogous. manufacturers have washed thier palms of the undertaking. I easily have been waiting to alleviate different popping interior of different gadgets utilising textile tape in places i've got faith could desire to be the reason, and loosening different screws between the cabinent and the panel interior the case of the plasmas. No possibility of fire---in any respect. manufacturers I bear in suggestions off hand with the undertaking---JVC, Samsung slimlines, Pioneer plasmas, Sony liquid crystal show rear projos. i'm specific my record from memory isn't finished--those are no longer all fashions of those manufacturers--regularly the themes are remoted to a particular kind from any kind.

most people under 24 can hear that high pitched sound. I used to be able to, but not anymore.

It is the picture tube. It usually does it right before it goes out. Experienced it first hand.
