I came up with this question right after I wanted to take apart a microwave to see why it wasn't heating anything before I remembered that that's a very, VERY bad idea

  • Laser / LED printers can blind you and may have larger capacitors.
  • Old CRT style TVs / Monitors can get you if not discharged correctly.

Is it true they can hold on to a charge for decades? I was told that but it seemed unlikely.

I'm treating them like guns. Assume they're loaded until you prove otherwise.

The coating on the inside of the tube can behave like a Leyden jar caps can accumulate charge over time even without an obvious power source.

That is my understanding. I remember hearing stories about dudes visiting a dump or whatever, kicking through the screen of a CRT and getting zapped like fuck

Unlikely. Even the best capacitors would discharge through leakage in 5 or 10 minutes.
