    One advantage of modern TVs is how slim they are. It’s so crazy to me now how much space those old TVs took up. You just had a big TV stand sticking out from the wall.

      I’m using an old console TV that I’ve modified to hold a flat screen. I literally have a home server and a sound bar built into it the space that was originally just the tube and there’s still enough space for my full grown ass to climb inside.

    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.

      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.

        Radioactivity and X-Rays are tangentially related, but they’re not at all the same thing.

          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.

      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.

            1.2 kg isn’t very much, especially for a dense piece of electronics.

            If you look at the history of iMac computers, when they went from CRTs to flat screens they only dropped 6 kg from 15.7 kg to 9.6 kg. Since then they’ve focused on making them lighter and lighter, but it’s not like the CRT was the majority of the weight.

      All of mine did but got increasingly quirkier over time. Sometimes you needed to hit it on top to get the picture looking right. Audio got crackly. The component cables needed a fine touch to display the picture correctly.

    I will forever remember using the magnet that came with this old Klutz book near the TV in my parents’ room when I was around 10 and noticing the rainbow pattern it made in the picture. And then, after further investigation and experimentation, noticing those colors stopped going away when I moved the magnet away. And then, never speaking a word of it. For, like, 40 years.

    When Bill Burr’s Netflix cartoon show put a similar bit in an episode it finally dawned on me that lots of kids must have messed up their parents’ TVs with those magnet wands.

                I have a Nvidia shield pro currently running Plex and Jellyfin (sometimes Jellyfin cannot decode the videos and trans-coding is off), I am thinking about moving away from that and go custom Linux build on a mini PC. For live TV I have the app from my internet provider, although I rarely use it. Because the shield runs AndroidTV you can basically just install Prime, Disney, Netflix, etc. apps to run those. For YouTube I use a modified app that has ad and sponsor block build in, can’t remember which one it is, but there are enough to choose from. Everything is routed through a Pi-Hole with dns enforced on the router to use it, instead of external ones (in case an app gets smart and tries to use their own). Next to the Shield I also have an extensive DVD/Blue ray collection, most of which have been moved to the NAS that has the Jellyfin server. There are still enough things to do, but I don’t have the time to do all the things I want to do.

          You know there are more variables that contribute to the quality of the TV than the resolution? Like how bright it gets or how accurate it’s colors are and what it’s color space coverages are… Or how deep the blacks are or if the pixel response is decent. I guess people draw the line at different places and most probably don’t care at all… I do, but I also consider my privacy as a variable here. I am in a niche group of people that are completely underserved as I have looked and have not found… So if someone claims they know of some I ask them for their wisdom.

        I think there was an art exhibit or something where they manufactured some new CRT TVs a couple years ago so apparently it’s doable on the small scale. Biggest problem is the current economy especially in the US simply couldn’t support small scale manufacturers like that long term.
