A "touchy" subject

[Brett B.]

My question when it comes to CRTs is what part will actually zap you? Caps, fly back, anode I already know but what about the tube itself?

Touching the glass part even while it's powered on is no big deal. Might get a little static zap if the humidity is low but no worse than petting the cat. Use the same logic as not touching any energized electrical component.

Correct, they implode, which can still be dangerous. Compact Mac screens are certainly less dangerous than smashing a huge TV intentionally, but I think it's still fair to keep in mind that you can end up with broken glass if you aren't careful.

Yeah, just saying, it's no worse than breaking a glass or bottler. You won't have shards flying in every direction or anything like that.

I'm scared of them, but I think it's a healthy thing to fear electricity. That kind of fear has the habit of keeping you alive and that's a good thing. Funnily enough I just bumped the board on a tube when I was taking out a hard drive and I heard the magic snakes escaping. I stood there dumbfounded with my hand over my mouth, the phrase, "What have I done?" leaking through my fingers like so many vacuums being destroyed. Now I have to swap a tube and I only have one left…

Another thing to note for @smrieck511 is to be careful if you need to detach the logicboard power cable - this is often when people accidentally hit the neck of the CRT with their hand as they pull hard on the logicboard cable. Once the CRT neck is broken, it's game over for that CRT and it would need replacing.

I know. What kind of doofus would knock the neck of a tube and break the vacuum? Me. I am that kind of doofus.
