The way they bleed the charge off when the TV is powered off is through a very high resistance resistor. This works perfectly well most of the time, but those resistors can and do fail. The same is true for microwaves, which also have flyback circuits. Always treat these things like the bleedoff resistor has failed.
Interesting thanks for the explanation!
Thanks, friend!

They’re really simple electronics, but there are likely a lot of little trade secrets that made them better. At the end of the day, it’s a cathode ray tube with a couple of electromagnets to divert a pulsing electron beam to hit different parts of the phosphor-coated end of the tube. The signal fed to the magnets is analog, and the beam sweeps the screen line-by-line every frame. (Or every other line for interpolated signals.)
It’s really not that dangerous. There’s a big capacitor called the flyback capacitor which can store a deadly amount of energy. You disconnect the power (obviously) and then discharge that cap and everything else is relatively safe. To discharge a capacitor, bridge the leads with an electricians screwdriver. If you don’t like sparks, hold a resistor with pliers between the two leads. (It will go slower but also get hot AF.)
Retro games look better on them and there’s no emulator that has ever pulled off a sufficiently convincing simulation for me. They also render dark colors better than most high end TVs. If you play a lot of old games, it would be neat to have a small one. The big ones, however, weigh a metric ton and are at least as deep as they are wide, and they’re extremely front-heavy. Those aren’t worth it unless you plan to build an entire arcade cabinet around it.
Yeah Gauss a unit of measurement for magnetic flux density. It’s not just there to make a BOING noise and briefly mess up the picture.
Coming from reddit, it’s interesting to see a world news forum that isn’t entirely and totally captured by Israeli Hasbara mods. I got banned from reddit’s /worldnews for pointing out that “invade Iran” vs “let Iran have nukes” is an asinine false dichotomy. (And I didn’t even use the word “asinine.”)
There are 4 pairs of 2 wires, for 8 overall. They are all used, but the pairs are redundant. From what I understand, when you send a positive pulse on, say, the solid blue wire, you also send a negative pulse on the stripy blue and white wire. The twisted pairs should counteract any interference, but if it doesn’t, the arrival of the bumps with opposite polarity should foolproof things a little.
Oh yeah it’s called differential signalling.
OK so I just learned, like, last week that there are two standards. Why are there two standards? WTF?
(The context is I was turning an Ethernet cable into an EtherCAT cable, which is a stupid industrial standard where you only wire up pins 1, 2, 3, and 6, and then charge the end user 200 times more for the cable.)
It feels like we’re losing ground. Why does 8GB of RAM feel totally insufficient to browse the same websites I used 12 years ago with 4? I’m so happy I maxed out my motherboard’s RAM (32) when I built a PC in 2021.
PROTIP:
Ebooks are trivially easy to find online, or you can check them out from your local library.
There’s a free and open source program called Calibre that can manage your ebook library, change file formats, edit visual formatting, and even remove proprietary DRM.
Don’t let Amazon being a bad company prevent you from using your old Kindle.
I just don’t see why they had to make X Men woke? Why does everything have to be about a persecuted minority group finding its standing in a society that fears it?
(tee hee)
And also Instagram and whatever other Zuck products are in your life. I’m happy they wasted so many billions of dollars setting of virtual Mii meetings lmao…
Japan is honorary Western.
(So is Korea.)
I want the latter, and tariffs are not the only way go about protectionism. There is also subsidization, which is how the US has maintained its defense and agriculture industries. If we want stuff made domestically, we’re going to have to pay for it. Subsidies are generally preferable to tariffs because they can be paid through progressive taxation instead of regressive taxes on consumers.
“We can’t let the environment be a deciding factor” is a preposterous take. There’s practically nothing more important that preserving the environment. Even the Chinese are looking beyond their borders for raw materials these days. If it costs more to extract raw materials in a way that doesn’t fuck up the environment, then subsidize it and pay for it. We can fund the subsidies with a carbon tax.
There are always trade-offs. All polymers deteriorate when exposed to that kind of thermal cycling and chemical exposure. A metal alloy fit for the job can last forever.
I haven’t used Linux regularly since 2006, which either means I’m out of the loop or an ancient bearer of lost knowledge:
I think it’s “G’noo” like “G’day” or “G’night.”
