As more and more television sets abandon the use of the CRT for displaying images, you will no longer be able to pass a room or a house and say, hey they've got a TV on in there. The infamous horizontal oscillator whine, at 15kHz or so, is a symbol of great human innovation and creativity, if you ask me.

A complex machine which conveys a full color motion image, with sound, to an audience hundreds of miles away.

Don't know about you guys, but the CRT is dying at an alarmingly fast rate, and I'm going to have one around for the rest of my life, even if it's a late-model-BPC set.

Standard-def is fine for me, considering how little I watch. :yes:

There are a few HD CRTs out there. Or at least there were for a while. I've seen three.

I haven't been able to hear the whine of a crt TV in years. We must lose the ability to hear high frequencies or something with age. I've mentioned that whine to people in the past and no one has ever seemed to know what I was talking about.

It's not all bad news. LCD is no CRT replacement, but OLED might be. And CRT's do have their drawbacks.

Still, CRT's are built sturdier. They have to be. :P

the "Chung" sound of the degauss coil
So that's what makes that sound. My trusty Sony KV-1311CR rings like the Liberty Bell when I turn it on.

I could hear it till i turned 30 something, In my late teens i could hear a operating tv monitor at over 20 feet away. It sucks to get old. :(

Reading this I realized I can still hear something from my TV in the dead quiet. This is funny to me as I have trouble distinguishing speech/music in situations with moderate background noise - been that way since my mid-20's.

When I was a kid, I could hear the whine as soon as I walked in a house with a TV running.

In a department store I could tell when there was a TV section close by!

Good riddance! I hate that whine. I'm the only one in my family who can hear it, they are oblivious to it. Sometimes I come into the room with the TV and its blank but still on, no one else would notice since they can't hear that it is still on.

And then they complain to ME about sometimes hearing my music a little bit.

We're still all CRT here. Thankfully. Hehe.

About the degauss circuit: I find that the noise gets louder as the set ages. In fact, I think the degauss circuit is one of the most common failures in a crt set.

I never heard the CRT whine. But then again, my hearing isn't the greatest. (and I'm 23 LOL)

Some come to say good bye to CRT's some say the flat panels are great.
HA! I am still watching a Sony KV27XBR with digital tuner and it works fine.
I work in radio and there are lots of reports that flat panel displays do not hold up very long especially if these monitors are left on for 24 hours. I have already had to repair LCD computer monitors little brother to the larger LCD TVs.
These are built poorly and generally made in China. How long do you think anything made in China is going to hold up? It's junk. You can have your flat panel and it is your money but I am sure that people will find out that all these LCD panels are really going to be nothing but a thing to replace at additional cost every two or three years. It's your money. The LED and OLED panels may be an improvement in picture quality but what if this expensive panel needs to be replaced inside or 3 years? To me it is junk. When are people who are suppose to be technologically enlightened going to get a clue.

When I was in high school I visited NBC, Burbank to watch them do the news from the control room. When I walked in there the whine was so loud and overpowering I almost felt ill. I asked if the sound bothered anyone in the room and no one could even hear it. Lucky for them. Couldn't wait to get the hell out of there...
