Everyone knows that's X-ray gas! :&
Just kidding. Actually what you heard was the sound of air rushing INTO the tube... it's under a vacuum... not any kind of gas running out.
The next question is why did you break the tube in the first place? It's absolutely unecessary.
I need to make a video... that guy's not doing it right. The only thing I like that he did was the way he handled the copper-wound ferrite... I've been cutting it up the middle with tinsnips. I think I'll try the smash & bash method on one.
He threw away some money, too. Stainless in the yoke, the whole base low board. Not much, but it adds up.
And there's NO REASON to break the glass. NONE!
I might take a coupla more minutes dismantling, but I make a helluva lot less mess, and end up with a bolted back together shell.
I didn't watch the video, I just found it from an earlier posting.

Yeah, that's a bad video. Always check to be sure the capacitors are discharged. No need to break the glass. I've accidentally broken a tube or two, and once watched some silver stuff float around like snowflakes. Not fun.
That was probably the phosphor powder.Quote:

Yeah, computer monitors are easily a better profit (potential) than a regular tv. I would guess-timate that you can make another buck or two for basically the same amount of work.
When I first started scrapping CRT's I'd scrapped about 5 or more, then I had one explode.Quote:

The broken sharp shards of glass covered a area of about 15ft dia & I could see the 'pressure wave' force of the actual explosion.
I had the screen up on one edge, sitting it on the rubbish bin & was using a flatblade screwdriver to try & slip the steel metal band from around the outer part of the screen. BOOMMB
I didn't even think at the time that the vacuum would give it soooo much force & because the screens made from 2 different sorts of glass, the join would be a structial weakpoint
First thing you do after discharging is put the longer screwdriver in the hole where the high voltage cup is attached and insert the screwdriver all the way in, you'll feel some resistance. That is a silicone seal and you have punctured it and released the pressure/vacuum.Quote:

This article will tell you all the in's and out's of safely handling the CRT tube. Including the dangers of implosion.
