Oscilloscopes didn't use magnetic deflection, for reasons. Coils need current, power, plates do not. Capacitive deflection is more suitable for measuring.
Nice video. For those of us old enough to remember these, even though they were black and white, it was considered quite a feat to get a TV that small. Back then TVs came in large wooden cases and were considered major pieces of furniture. I remember as a kid seeing TVs about this size attached to most seats in airports. You would feed quarters into it so you could watch TV while you waited for your flight. I think a quarter would get you 10 minutes.
Well explained! One of my first projects as a kid was adding a composite video input to a (larger) black and white TV. There's something special about the smell of that cheap paper and resin single sided pcb.
May want to mention that the CRT acts as a capacitor, which will hold high voltage, even without power connected. Putting a screwdriver under the rubber insulator to remove the clip will usually cause a loud spark discharging it. Can be quite painful!
I have an idea: Vintage Rebuild of ToreDown (of course you can give it a Brand new name) : a new series where you re-build the tore down items into a new one (and a bit upgraded and useful, like TV used with an old computer), or make entire new thing out of them, like ...um.......whatever you think of......[ :) hehe], or you can reconstruct any old, broken vintage item into a working, functional one!! This way, we can *learn more*!
I wonder if you could use the TV tuner to pick up wireless mics that broadcast in the UHF/VHF range. Anyone know? I realize it would be kind of pointless but I haven’t taken a COMMs course yet and am curious!
Yes, that would be a laser usually. But best to modulate using FSK and send as a digital signal. You can also make a audio transmitter using an IR diode and modulate it as an FM signal.
I have a very similar tv I am trying to remove many components and shrink it's size and make it only accept the yellow AV input. Could you help me figure out how to remove the stuff I don't need? Like the UHF/VHF and FM/AM radio? I am using this for raspberry pi project.
Could you plzz make a tutorial about arduino timerz programing 😊😊 it always mind boggle that how it works and i cant understand it plzz make a viedo about it 😀😀
I suggest you look at getting your amateur radio license and you'll learn a lot more about RF and Analogue/digital circuits. But you will also be licensed to experiment using them too!
This thing is from around 2000. There were more advanced crt sets around long before. Smaller, and color, even flat CRTs. This TV is just cheap. It's cheap, because of the highly integrated ICs, available at the time.
What you did not explain, is the purpose of the flyback transformer and the principle of flyback in a TV. The deflection coils paint the image on the screen, one line at a time and in an alternate sequence. First it paints lines 1, 3, 5, 7...etc. and them it paints lines 2, 4, 6, 8...etc. In other words, the electron gun must trace the screen top to bottom twice to form one frame of video. In the USA one screen was 525 lines. The flyback transformer is used to return the electron beam after each line is drawn. Here is a link to a picture that shows the scan lines and the flyback: i.stack.imgur.com/Vl9yA.jpg Picture tubes are big capacitors and even after power is removed can contain a charge such that if you touch the second anode (the suction cup), you could get a shock of several thousand volts. (The rule of thumb was that there is approx. 1,000V per diagonal inch of screen. The higher the voltage gradient from cathode to the second anode, the more clear and sharp the picture would be). Always discharge the picture tube before removing the second anode. This can be done by connecting an alligator jumper from a screwdriver to the chassis of the TV and then putting the screwdriver under the suction cup so that it touches the conductor of the second anode. Here in the USA, the horizontal scan frequency was 15.75KHz and sometimes it could be heard. Those transistors that are mounted on the heat sinks are most likely the horizontal oscillator that produces that frequency. So...as the electron gun paints a line across the screen, the inductive flyback transformer winding is developing a voltage on it. When the beam reaches the end of scan line, the circuit to the flyback winding is opened and the voltage produced is thousands of volts in the opposite polarity forcing the beam very quickly to the other side of the screen where a new scan line can start. This is the same principle that is used in the ignition system in your automobile. If you ever wondered how 12V can arc across a spark plug, this is how. The coil in your car is basically a flyback transformer and in the old days, the points (now electronic switches), opened to release the energy from the coil. You can also see my video on flyback if you're interested: ua-cam.com/video/uV5AdF1ljDA/v-deo.html
or better yet connect the rf out of a cable box to a signal booster, and connect the output to a rabbetear to make it completely wireless and modern with youtube and everything! at least if you have xfinity x1 you will have all the cool steaming capabilities
It’s VERY DANGEROUS 💀 handling a CRT television, the tube holds a high voltage charge like a capacitor. You MUST first discharge the tube with a suitable tool. It’s not a good idea playing around unless you are SURE it’s discharged.

You can create an analog oscilloscope with an old TV by using the deflection coils you can guide the signal.
That would be a cool project..
Great idea

Retro-Tech is so cool :)
Am I the one here, who's shocks about the GMA's Affordabox as an example? Is there also filipino's watching this?
Me always hahah
Every time I see your new video ,
My excitment levels go high.
Thanks for sharing your knowledge
That looks like a handy little tv.
greetings gentleman

or like ordering a cheeseburger from the now put back together torndown black and white portable TV!

I also want to know.
your video show all detail of that tv, thanks for video...
Amazing!! Love from India 🚀
great video , but still I wonder how does the demodulator work ? sounds complicated .
Can we make a camera which can transmit video wirelessly for this kind of tv🧐
great video
Your awesome.thankyou very much for explaining about this tv
Can we use light to send pictures and videos using analog signals instead of radio waves??
Yes, that would be a laser usually. But best to modulate using FSK and send as a digital signal. You can also make a audio transmitter using an IR diode and modulate it as an FM signal.
I like your new segment Vintage Teardown. I learned a lot of new things in this video.
I upcycled one of these into a mini working Mac classic out of rpi
Cool!
@@hugobracamontesbaltazar I know !

I never heard orchid pronounced like that. Please don't mind. I would like to see more of vintage teardown videos.
Hahaha🤣🤣
Dudeee. That intro is DOPE.
Thanks :)))
Very informative and very interesting
U deserve alot more man
I suggest Old vacuum tube radios Teardown & vintage refrigerator
Could you plzz make a tutorial about arduino timerz programing 😊😊 it always mind boggle that how it works and i cant understand it plzz make a viedo about it 😀😀
I have that on my to do list!
@@ELECTRONOOBS okk sir iam a huge fan of electronics creators 😍😍

I need more videos like this, I learnt new stuff things. Tq man by staring these videos.
How to use this tv with ardunio by genrating video signal
You could try a transmitter for video what is used for FPV Drone Racing? This must be analog?
This thing is from around 2000. There were more advanced crt sets around long before. Smaller, and color, even flat CRTs. This TV is just cheap. It's cheap, because of the highly integrated ICs, available at the time.
As always really good
Could you please say what is the software you used for creating animations? Please...
Excelente video! Podrias hacer uno sobre high-side y low-side switches y cuado se usa una u otra configuracion? Gracias
Dude your english became amazing since I've starting watching your channel when you EEVBLOG shared you :D
The quality of the video is stellar 👌
Oh. Thank you! Means a lot to me!
*Podrías hacer unos Smart Glasses ?*
Plz make a motherboard teardown video. (The IC's capacitors and many electronic component on it).
Imagine. A consumer electronics device that's repairable.
interesting :) there are not dust in TV
Why not Make analog tv transmitter?
YESSSSSSS!! 1st like, 7th view, 1 comment! Best so far

Awesome make more vids.
Orchid is pronounced like - "or'-kid"
Awesome make more about crt and it's flyback converter
It is very clean board
I open my tv 📺 it was full of dust
bro, please make an oscilloscope with this
GreatScott! made one such project.
/@@oniruddhoalam2039 yes but I want to see him video
👍
I still need the video of large tesla coil....
Hi try make a hologram glass.
All you have to do is get a digital analog TV converter box
or better yet connect the rf out of a cable box to a signal booster, and connect the output to a rabbetear to make it completely wireless and modern with youtube and everything!
at least if you have xfinity x1 you will have all the cool steaming capabilities
You can make a video on CRO.
It’s VERY DANGEROUS 💀 handling a CRT television, the tube holds a high voltage charge like a capacitor. You MUST first discharge the tube with a suitable tool. It’s not a good idea playing around unless you are SURE it’s discharged.
Everything was discharged. Thanks!
Iam the first one to like
But this is not that old. These TVs were introduced around 30 years ago but they quickly lost the battle to lcd.
Alpha mods)) why so few comments?)
Bro pls make a project with nodemcu(esp8266)
🙏🙏🙏
no pixels on a crt.
Please make smartphone control dron
Not quite accurate but ok, I guess since this is already old technology and most probably will never be used....

Theory of operation as presented is fundamentally flawed - this guy does not have a clue
Wow you are filipino
