    Our TV was from the early '70s and when you turned it on if you weren’t at least 10 ft back the hair would stand up on your arms. I’m sure that thing was definitely giving you a suntan.

    Let’s not pretend that crts ware better than modern TVs. The picture was shit, the ratio was 4:3 and they had the size and weight of a small car. I can deal with a little upgrade once in a while. And that’s not even true as I haven’t seen a TV that needs upgrades yet.

    They’re not really radioactive, they emit some X Ray that is absorbed by the lead window that is in front, making them harmless.

    I think that’s some major rose-colored-glasses thinking. They did break. A child with a magnet could also cause issues, at least on older ones (I say having been said child).

      I had some unshielded noise speakers that would change the color when swiped across the screen in one direction. And cleared it when swiped the other direction. Fun times!

      Circa late 1980s I remember our dad brought home a degauser from work, hey anyone remember what a degauser is? It was a magnetic box (VERY STRONG MAGNETS) with a tunnel to slide a cassette tape through, to erase the cassette tape. Well I don’t remember which of us family members decided its storage place should be on top of the TV but what a fun science lesson that turned out to be 😄 If you moved the magnet around the TV in all different places, the distortion on the screen would follow wherever the magnet was, and IIRC the screen distortion wasn’t permanent. The screen went back to normal when you removed the magnet from the vicinity.

        IIRC It messes with the beam guides. I’m not sure if there are cases/designs in which it would cause permanent damage in color TVs, but I seem to think I managed to permanently tint our older one green somehow.

    i finally got mine out of storage and set up

    it turned on 3 times and the kids got to see the static. they got to hear the super high pitched wine

    but now it doesn’t respond to anything 😭😭

    I’ll try to get it fixed one day 😓

      While it may not be related I have a CRT monitor that did something kinda similar and which I think I know what it is so I’ll give a suggestion. It may legit just be one of the internal boards or whatever equivalent that controls power and may just need to be resoddered or otherwise replaced.

    The only thing that modern TVs beat CRTs on is weight.

    I’d rather have my 200lbs behemoth CRT back, than to have a smart TV thats just gonna die in 3 to 5 years, just like the last one, and the one before it.

      This is just stupid. Size, weight, picture ratio, picture quality, sound quality, compatibility, functionality. A modern TV is better at literally everything. Don’t just blindly agree with something just because it’s on a meme.

      Size is also one. Modern tv can scale the length and height up without scaling much of the width. Dumb TV also doesn’t need internet to update. Pretty sure smart tv doesn’t need update as well. It’s not that CRT is the best, we just forgot how to make a good LCD tv.

    Projector is the best non-smart TV in 2026, the name brand projectors (ViewSonic, BenQ, Phillips, Optoma, Epson) are often either non-smart or just come with a streaming stick you don’t have to use.

    Just in case anybody is stupid enough to believe this, there was nothing radioactive in old CRT-based TVs. And they sometimes had black cases but weren’t a “black box”.

    They worked by bending a beam of electrons that hit phosphors in the screen, which is cool enough that saying stupid BS about “radioactive” is unnecessary.

      beam of electrons

      Let’s say it cooler: they were particle accelerators you pointed at your face.

      Also, massive glass vacuum bottles that could implode if mishandled.

      And with massive capacitors that could electrocute you if mishandled.

      And heavy enough to seriously crush your foot (and possibly implode and electrocute you) if mishandled.

      And the static electricity felt really neat on the back of your hand if you put it close to the screen.

      They were so fucking cool, and we took them for granted, and now they’re gone, and life is significantly less cool without them.

          TVs, maybe¹. CRT monitors, though? They were great. And mostly didn’t care about what resolution you threw at them.

          1. It’s a big maybe, though. Live TV? Sure, but that was more on the extremely low resolution signal than on the screen (HDTV would’ve looked great on a CRT). But games? They were fantastic for games, though. Artists designed their images with CRT’s natural blur on mind, and now we need complex filters and at least a 4K monitor to replicate the original look.

      CRTs can emit X-Rays, but they are properly shielded so they never leave the tube.

      The X-Ray scare mostly came from a line of GE TV’s in 1968 that had improper shielding and had to be recalled.

          One is from a decaying material and the other is from controlled electron beam, but they are both radiation emitters. People are just more familiar with the term radioactive and think it is the catch-all term for a source of radiation.

          The electron gun in a tv and in an xray machine are pretty similar and without shielding, you will still get hit with radiation even if it isn’t strictly radioactive, but rather another type of radiation emitter.

            One is from a decaying material

            Specifically radioactive decay.

            the other is from controlled electron beam

            So, not radioactivity.

            Radiation is a really vague term. It’s just energy moving in the form of waves or particles. Sunlight is radiation. Radio waves are radiation. Microwaves are radiation. Wifi is radiation.

            Radiation can be dangerous in a few ways. Something can be very bright and blind you, or it can cause you to heat up too much. X-rays are an example of ionizing radiation, that’s dangerous because it can break apart molecular bonds, causing damage to cells. That’s why you can get skin cancer from ultraviolet radiation. X-rays are a shorter wavelength than ultraviolet light, so there’s more potential cellular damage per photon.

            But, radioactivity is dangerous not just because of X-rays, but primarily because of alpha and beta particles, and because of even higher energy particles like gamma particles / rays.

            So, just because there’s one type of ionizing radiation that can come from a CRT-TV that is also peripherally associated with radioactive decay doesn’t mean that there’s any connection between a TV and radioactivity.

            That would be like saying that an atomic bomb causes a huge explosion, and a fertilizer bomb also causes a huge explosion, so a fertilizer bomb is a nuke.

        Barium glass.

        Leaded glass was only used for the rear of the tube (or amber monochrome displays), the front glass was barium infused for colour CRTs.
