All the TVs I've done before, the core was held on by some screws. But this one, it looks like some kind of glue. Is there any way to get this off without breaking the glass?

pics would help
i think i know what ur talking about
they are tricky- many times the glass cracks.
There's always the option of taking a pass on the ones that give you a problem.
The picture tube is under a vacuum. You have to be careful working around the end of the tube because if you break it the picture tube can implode. Then ... you've got shards of glass along with lead, and mercury that have contaminated your workspace.
All of that mess to clean up for maybe a pound of copper ?
Doesn't seem like it would be worth it. :&
Is the brand RCA??
Never had a tv implode by removing the yoke..or breaking the area around it. I'd try very hard to avoid breaking it. If you can pass it over I would. Their a pita.
If you do get it off you'll have glass in the yoke area due to the glue/whatever they use to bind it there. If you must break that area, face the tv down, an tap gently the glass will fall in to the tv shadow mask( Think that's the name of the metal in there). I've broken that area once or twice when I first got those kind an they broke from me trying to force it off..lol..which doesn't work, lest not for me.
I got a place that will take my tubes tho regardless if stripped or not. I just let them know if I have any like this. It's rare but happens sometimes. I also pick up ones on the side of the road that have been smashed is possible, an turn them in.
Good luck with it, an I wouldn't worry to much about it imploding unless your doing something stupid like those fools on youtube do for their videos. Oh an when I've had it happen I've never had glass go everywhere it all falls in, unless it happens when standing. I try very hard to avoid breaking things if possible, but sometimes **** happens. ;) I also always strip them with the screen down, yoke up.
I'd pass it up tho if possible, really not worth the hassle of clean up an disposal if anything should break. Thankfully I don't get many of those "glued" on types anymore. They suck.
Sirscrapalot - Break glass in case of emergency.
Oh an use eye wear to protect your eyes, an of course gloves.
Better safe then sorry.
Sirscrapalot - The picture of safety an has the scars to prove it.
Definitely second that. :)Quote:

That's never fun. ;)
Sirscrapalot - Has had a cigarette to the eye before. Not fun.
3 licks should do it. :))
It doesn't have to come off .You can still break it up on the tube, just a little more carefully.
Yeah, I had to bust it. And it was a pain in the butt. Unfortunately, it was one of a load I got from a hotel. Most of them had a screw-on yoke, but that one confused me!
Don't forget that the bottom clamp is usually SS and the top one is SS with a regular screw.Quote:

If you dont wanna do that try scoring the glue with a knife and pulling it off, or possibly if its plastic like and would melt easy melt it off with a small plumbing torch. If it was me I wouldn't spend more than a minute on it.
So I got it off, but now it's got that thick epoxy stuff on it. Is there any chemical way to get that stuff to dissolve?
Just turn in as is. My yard doesn't care. i remove all i can, but don't go all out.
Even if you get it off, it's still varnished. Just take the #2 price an call it a day. Time you could be spending dismantling more tv's, pulling wire, speakers, etc.
YMMV
Sirscrapalot - Yodeling while yanking yokes.
Then you'll have more money involved than what you can get out of it. It'll go in the #2 bucket, after getting off what you can.Quote:

I know you already got it off, but I just saw this thread. I have some old IBM monitors that are stuck really good with that epoxy stuff. What I do is find the 4 rubber pieces that are glued to the yoke and the tube, lift and peel each one so that they aren't gripping it anymore. Then hold the whole tube still and grab the yoke with both hands and twist with firm even pressure. Sometimes you have to twist pretty hard, but they usually break loose. I've never broken a tube at all using this method.
I allways smash the tube. ALLWAYS!
Mostly I do it with a 3 foot long steel bar. I take a big swipe across the board stuck to the end of the tube.
I used to just rotate the board and let it crack the end of the tube and listen to the air whistle in.
That's fun when there's someone watching... I get ready, breathe in and out a few times, take a deep breath, then twist a crack, let the air go in slowly, then run about 20 feet away and inhale.
Because the watcher don't know what I'm doing, I say "You don't want to inhale that gas, its dangerous".....
Small thing amuse creative minds...
But, with the long bar thing, I crack most of the end tube and don't have to worry about the clamps, it all falls into the tube.
Now, I know what you are thinking... 'he smashs the tube!!!!'
Well, one day, when I first started scrapping CRTs, I have the full vacum tube sitting on the top of the rubbish bin, I insert a flat screwdriver under the band to lever it off and BOOM!!!!!!!!
I'm standing there with the band in my left hand, screwdriver in the right hand and a ten foot radius of glass shards.
I actually saw the shockwave from the explosion.
The shards, they were a square profile, from about a inch long, to three or four long.
They completly covered the ground around me, the only bit missing was where I was standing.
I still can't believe I didn't get cut, let alone blinded. God was looking out for me then, I know.
In hindsight, what I had done was crack it on its weak point, the connection between the two glasses.
It cracked right around there and the vacuum did the rest.
Untill you have seen it, you won't understand the pent up power instilled into these screens.
Also, don't trust the band around the screen, it may have been tight once... but it may get loose.
If you pick up a screen by the band, the actual screen may fall out of it.
I leave the screen in the plastic case. Devacuum, remove coil, cut the red wire to the suction cup looking bit, then pull out the degausing cable after covering the broken end of the tube with something.
I cut the red wire because if you don't, when you pull out the degaussing cable, if you yank it, the 'flyback transformer' will 'fly back' out at you, normally smacking you in the face.
Then I remove the board to get the components and refit the back of the tv casing.
Ok, people do this all differently, but that's how I do it. One explosion was enough to teach me that that's the most dangerous thing in scrapping except maybe loosening the band around the brake housing of the vacuum brakes of a truck....
Nah, the CRT was more dangerous.
