CRT tube - Releasing vacuum for tube removal/disposal

Simon Webberist · 2006-08-23T14:21:47+00:00

I need to remove the picture tube from a 14" computer monitor. I'd like to release the vacuum first because i think i should before i remove the tensioned wires holding in the tube. I have removed the neck board and can now see the indexing plastic of the socket. That indexing plastic is siliconed on with white silicon and i can't seperate it with a knife. I'm thinking of using a dremel to saw through the indexing plastic as that is where i'm thinking i should be filing then snapping off anyway.Does this sound like the way to go? I really want to release the vacuum. How do people usually let out the vacuum?I pulled off the Ultor cap where the annode lead attaches, but it's all glass under it, theres no metal i can drill.from the faq:with an unwanted vacuum?)without spectacular effects by breaking the glass sealin the center of the CRT socket (may be hidden by the indexing plastic of thesocket). Cover the entire CRT with a heavy blanket when doing this foradditional protection. Once the vacuum is gone, it is just a big glass bottlethough there may beI tried searching google, but I couldn't come up with anything except the same FAQ.Thanks,Simon

Its more fun to use a very small triangle file. File a groove in the seal at the end of the neck, till it just barely starts to hiss, then see people running out every door. Yes, I DO have a very warped sense of humor, but I have done this a few times. One of them hissed for days.;-)

The file gives a very faint hiss. First they are looking for the sound, then they freak out. ;-)
