The 15750 Hz “Noise” from my TV is driving me NUTS!

Can anyone else hear the 15750 Hz tone generated by most TVs? My girlfriend was telling me I was crazy and that the sound didn't exist until my Uncle Chuck explained that the sound does exist while we were back in Illinois for my Grandmother's birthday & Christmas.

I've got two TVs in my apartment (a 15-ish-year-old 20" GE and a 3-year-old 36" Toshiba) and I can hear both if they are on no matter where I am in the apartment (2 BR/2 BA, separate kitchen & dining room; it's not a small place), even if the doors are closed.

I'm almost ready to go out and spend $3000 on a nice 1080p LCD screen so that I can sit in the living room in peace because even turning the volume way up (with 500W of Klipsch power behind it) doesn't drown it out... Heh, the only good news is that all of the big-box retail stores are getting rid of their CRT screens (or at least tossing them in the back corner of the store) so if I do break down and decide to go shopping, at least I won't get a headache at the same time.
