tv stems - Page 3

Seriously. All these people always worrying about getting "blown up". I'll make an estimate, i've torn down probably about....somewhere between 5, and 10,000 TV's and monitors. All WITHOUT gloves. Do wear proper eye protection however.

I take the suction cup off, use my All, and a hammer, and air the tube. I'm not breaking any glass, every thing is still safe, and i dont have to have my guys handle a tube that is still under vacuum. I've noticed with my experience, that tubes still under vacuum tend to be easier to "break" when sat down, and moved around. When they've been "aired" as i call it, it seems like it's tougher too break them. I do NOT intentionally do it. Sometimes chit happens. I never could understand why people freak out about working on TV's. Yes i know i've had my ding dong zapped before, but you live and learn. Now i do it a safer way. (Not on my danged tailgate).

Bottom line is this: You do NOT have to break ANYTHING to get the cone off. No process of your dismantling should involve breaking any glass.

Now please, i'm tired of explaining this. Let the **** horse die already.

If you're taking the metal band off, definitely make sure it's "aired down". I believe that band is to minimize shrapnel if it explodes/implodes...according to this site.

It's a lonnngggg read, but we'll all learn something. I know I did. "A large CRT will have over 10 tons of air pressure attempting to crush it". Don't know if it's factual. Seems hard to believe.

Just unscrew the 2 clamps on the yoke/tube and twist it off. RCA tv's are the "glued" ones. not break it man.

You seem to all be agreeing to disagree. Back to square one.

Everyone who handles crt's should read the sections that pertain to this topic in the material that Idaho posted above. It speaks to each issue in this thread and elaborates on the issue of implosion that Hoss brought up. I kicked myself for not "getting" this sooner. The "expert" there agrees with Hoss, it makes handling of the crt safer to "air" it. These experts recommended the way Hoss does it OR the way Dune does it. SO NOW WE KNOW. We "usually" only beat a horse if someone still has questions ! Thank you Russell, for your insistence on a definitive answer and thank you tator for posting that site. Now, if you'll excuse me, I have around a hundred crt's in my backyard I need to diffuse !!

I break the little glass pigtail in the centre of the plug & let the air in that way, or just wiggle/bash the circuit board untill it breaks & then I wait for the 'woosh' of the incoming air to end before I start work on the tube.

I had one of the vacuum tubes explode on me one, something that they can all do when they still are under vacuum.
Pretty **** scarey (sic).

If you have never had one explode on you, you have no idea of the danger & explosion risk that they pose.

Don't pick them up by the steel band, they are not all tight & you may end up dropping the screen out of the band.

And here I thought I was the only one.

When I worked in construction, we had a term for guys like that. We called them "hammer mechanics." And it's not a complimentary term.

There are several Youtube videos of workers in businesses that totally dismantle crt tubes for recycling. The phosphor coating is on the inside of the face of the tube and in these videos one of the workers usually uses an industrial vacuum attachment to remove the coating. The crt's are normally cut into by mechanized machinery and the funnel or back part of the crt that contains all of the lead is removed and sorted into a like pile. The unleaded portion of the crt is vacuumed clean of the phosphor coating and the piece of glass is sorted into an "unleaded" pile. There is also a steel internal frame within the crt that is recycled and the metal band is cut or grinded off. Interesting process!!!
