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 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 dropped mine down the stairs, the implosion from the vacuum tube was pretty impressive.
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.
TVs have their own degaussing coil built-in, it's the short buzz you hear first when the TV is turned on.
If the metal frame around the front of the tube becomes strongly magnetized, that's when the distortion is "permanent", meaning it's not permanent but not really feasible to fix.
We tried with magnet, no where as strong as the ones you've mentioned, but still, it messed up the image. It was fun.
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!

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.
The TV wasn't permanently messed up, you just needed to degauss it.
oh so thats what degauss does
Klutz books were truly amazing. I had that one and several others, and they were incredibly formative for me.
Crt tvs broke all the time.
I know, right? I've gone through like 4 in my lifetime and I haven't owned any in over a decade lol
Remember when the tube started to go and you had to leave it on all the time or whack the side of it when you first turned it on for the day, until it warmed up?
Rose tinted glasses.
they will record you anyways and store the recordings and transcripts long enough that if a future owner of the TV ever connects it, it'll upload all that shit it's stored.
and they know what wifi networks and hardware addresses are nearby so those recordings will be associated with your location even if it uploads them from another physical location.
these things are all advanced wiretaps that should probably have their antennas permanently destroyed.
You just typed all that on the biggest wiretaps of all.
Summit for Lemmy on GrapheneOS is a wiretap?
Firefox with ublock, noscript, and privacybadger on cachyOS is a wiretap?
cuz I posted this from one of those two.
The AI 20 years from now cross referencing every possible point of data to deduce every single identifiable feature to pin you as the guy who forgot to pay for the gum is going to have a field day with this post.
It's all a wiretap at this point in my head. I think it's just a matter of how much effort and time a (probably government) entity wants to take to track people down or grab someone.
Like the NSA didn't build a gigantic data warehouse in Utah to not fill it with a database of every person they could.
I'm sorry you feel so defeated that you can't even appreciate folks who are still fighting where they can.
NSA can't warehouse data that never gets generated in the first place.
Fun fact: These TVs also had a self-defense system built in. One wring move with a screwdriver and they'd throw you across the room.
There was a time when CRT TVs were so cranky and reliably in need of service that your local drugstore had a rack of replacement tubes and even a tube-tester machine. You could pull a bunch of tubes from your set, test them at the store, and buy a replacement for whichever one was bad.
I run a valve (tube) amp as my daily driver for audio and yeah, you do have to have a screw loose in this day and age. They're a lot better with modern passive components but modern valves are pretty hopeless in terms of longevity. For EL84s you basically have to buy old Soviet military stock (thank fuck Gosplan was so hilariously inefficient) or your amp will burn through them fairly quickly.
On the other hand if you look after them will probably outlive you. The valves are consumable components but the transformer is literally a big chunk of iron and copper, and they're dead simple to work on usually. Modern capacitors don't dry out and turn into resistors nearly as readily too.
The way CRTs work is absolutely amazing. You're basically watching a ray gun shoot you and it's so quick it looks like a picture. It's an absolutely wild marvel of engineering.
All I want is a brand new CRT that I can connect my PSOne to, so that I can play Point Blank 1-3 again.
I would love for CRTs to be manufactured again, but that instutitional knowledge is probably long gone, as is the equipment that produced it.. so making them again would, probably, be a trillion dollar ordeal.
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.
"your TV needs to install an update, please connect to the internet", it says
how did it know it needed an update?
I am 60% sure I have seen this happen IRL
I have seen it mentioned in other threads that they may connect to open hotshots.
I don't know how true this is, but it would make sense.
I am 99.9% sure that is true, I just don't remember exactly which source I saw it in
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.
But by fuck was their capacity to put out a clear image mid. But their screen size on the other hand …extremely limited
TVs, maybe¹. CRT monitors, though? They were great. And mostly didn't care about what resolution you threw at them.
- 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.

What game is this?
They looked amazing for games designed for them, specifically because they blurred the pixels. If what you want is crisp lines or vivid colors, CRT works against you
If you squint, you can make the right side look like the left side. Kind of amazing. Instantly increase resolution with this one weird trick.
And heavy enough to seriously crush your foot (and possibly implode and electrocute you) if mishandled.
Sometimes. Other times they were little portable things.
I mean, sure. But even this little 4'' “pocket” thing, for instance, still weighed 1.2Kg... that's a damn dense (and expensive) brick to drop on a toe...

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.
they did emit x rays but most of them was blocked by the leaded glass
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.
Radioactivity and X-Rays are tangentially related, but they're not at all the same thing.
I like this comment except for the fact it seems needlessly hostile
Someone not knowing there's a difference between "radiation" and "radioactivity" doesn't make them stupid.
No, just ignorant. Very ignorant.
It's the equivalent of knowing the difference between "poisonous" and "venomous"
For the vast majority of people it doesn't matter. Maybe they learned in 8th grade, but they forgot, because it never came back up.
Not really. Radiation is something you encounter every day. Radioactivity is something you probably never encounter. Most people except Australians rarely encounter poisonous and venomous animals.
