    Do not disassemble a CRT on a whim. Even if you’re being careful, it can go wrong. There’s strong magnets, glass under pressure, capacitors that can hold a deadly charge for a long time, and toxic chemicals.

      The cathode tube itself can hold thousands of volts for a damn long time.

      OP I hope you knew how to discharge all that shit and how to dispose of that thing

      Strong magnets? That’s not something I’ve ever come across having worked on several CRTs

        They are part of the deflection yoke. If you saw that chunky core wrapped in magnet wire on the skinny end of the tube that’s what that was. They aren’t always permanent magnets, most of the later model TVs used electromagnets, but it’s how the electron beam is moved across the screen. All of them will have very strong magnets somewhere by design.

          Ok, I thought you meant permanent magnets. Of course I know about the deflection coils. There are also some small permanent magnets for the convergence

          Shout out to Philo T Farnsworth!

          He grew up in Idaho and the small town he hailed from had a sign calling themselves the ‘Birthplace of TV’. That sign was frequently vandalized to read ‘Birthplace of VD’.

          Both statements have some validity.

          Philo, Father of TV

      Woo magnets, how hard would it be to disassemble them with care?

      I have 3 old TVs I want to get rid of but haven’t yet.

        I have gotten rid of TV’s before without disassembling them first. I am living proof, it’s possible
