So I've got a busted 14" CRT in my garage. I had it sitting on top of a styrofoam cooler (dumb on my part) and I guess at some point the cooler must have shifted or collapsed, since I found the monitor on the floor of the garage and very much in dead condition (huge crack in the glass).

Anything that can be harvested from these for electronics projects or am I better off taking it to the recycling center? I really wanted to use this as a VGA display either for the Tandy (w/ vga card) or one of the 486 boxes I'm working on, I should have had better sense than to set it there. Lesson learned I guess.

Drop it off for recycling @ Goodwill / Best Buy. No point risking your life playing around with the insides. 😊

If the screen is cracked then it's done for. But if you're into electronics the main circuit board is chocked full of awesome goodies, keep it! 😉

My days of extensive electronics dickery are about 20 years in the past, and I don't feel like stopping my heart if I accidentally touch the capacitor.
I think I'll just take it to the recycling center.

If the thing has been sitting unplugged for months nothing's gonna keep any residual charge, but yeah unless you're really into electronics, it's not worth the hassle.

Most electronic components are really cheap so not worth the time spent desoldering / testing IMO.

Some are proprietary and/or hard to find though. I'd say keep the circuit board, ditch the rest (although I'd dissect the tube just because it's interesting to see what's inside and how it works)

Yeah most small passive components (resistors, capacitors, etc) are dirt cheap, but high power components are usually a bit more expensive. A CRT monitor is full of high power circuits, therefore nice big caps, coils, relays, amplifier ICs, transistors and the like.

Safe answer: recycle it and clean up any glass debris.

Not safe answer: build a CRT Jacob's Ladder: https://www.youtube.com/watch?v=va1LkxQx3Zc (afrotech has changed too much to link to that, but they used to have a guide)
