I built CRT TV from a kit I found on Ali Express, and you can too! #aliexpress #diy #retro

Hey everyone! Thanks for watching and all the comments. I wanted to make a post in regards to some of the common questions, and give a teaser for the follow up. I have put the original transformer back and and even applied 220V, no change. I used DC, no change. I replaced some components....change. I have a second unit now I am building with better components...stay tuned to see how that works!

I hope new CRTs can be made somehow! What you’ve done and what you’ve been able to source are a good start, but I hope we one day see a future where we are all guaranteed to be able to play games like Duck Hunt, Dr. Mario etc the way they’re meant to be played!
Someone on Facebook just told me “new CRTs are impossible to make, making the leaded glass required would break environmental laws worldwide”, surely CRT glass doesn’t need lead? Surely there’s another way?
I agree we need to reduce our carbon footprint, especially in light of how hot the last 2 summers were (which were the last 2 winters in the southern hemisphere) but I still think there should be ways we can still enjoy doing what we do, while still not harming the environment! I’m sure people once said there’d “never” be an animal-safe substitute for ivory, but many have been found over the years since!

Suggestions: 1. Increase the voltage and ampere of power supply, you can use a variable voltage lab power supply but be careful as over voltage will surely fry the unit. 2. Please check if Horizontal and Vertical connection of yoke coil are not interchanged. Please do let me know the result. I am excited.

Good Job, I'm delighted to watch that. Keep it up. God Bless You.

gracias!!! por el diagrama!!!, saludos

Hey, you never posted an update to this project. I'd like to see this running right.

Sir in my portable 12v bw tv a vertical line appeared in the centre of screen what happened to my tv 0please help me

We shouldn't have to make our own. They won't give us what we want.

Use( transistor 8550) on vertical section picture will get bigger

U.K. has been doing this for years.

Can you make a video of this when it is playing music (To show screen jumping)?

Good luck got love you 😍

Is it supposed to be monochrome, or is it a PAL/SECAM TV receiving NTSC signals?

Hi! Brilliant! What is the code or characteristics of the transistor that you show almost at the end of the assembly and is placed on the heat dissipating aluminum plate? Thank you.

Where’s the link I can’t find one

Cool bro! Please can you tell me: it's black and white, right? Any possibilities to have colors?

You build a chassis, not a CRT.

Did you recap it?

2022 model crt?

I hate CRT displays (I have very little tolerance for flicker), but I still ended up watching this.

I wonder: could this be a basis for a DIY monitor for use with an MDA/Hercules video card?

I build tube amps from China but I don't use their components but source all resistors and caps locally just to play it safe.

but very expensive. rather just buy from offline parts market.

Can you do another video of this with better material starting from scratch. I would like a color tv demonstration if you can.

Also I don't recommend leaving that CRT on for so long in the case of not enough width and height because it's concentrating all the light on a small area which can cause burn-in.

Glad I got a few CRTs when they were being tossed out. I sat some VCR combo on the curb and it was gone in an hour. I believe the buttons were shorting as it would wake up and do strange things in the middle of the night.

Who built that circuit board to be able to program the tv to work? If they suck at it, perhaps we can do better? And who built the cathrode glass tube? Is all this from China?

alibaba sells crt tvs as a whole

Funny Man

I wish it was color! I need something for my WS4000 emulator.

It´s really good for training. Finally you have really your own and absolutely original TV. :-)))

You're a legend and you've gained yourself a new subscriber! I wish one day when I grow up to build a CRT TV for my own future house!

Hello;;your problem with small picture,push the yoke all the way forward until stops,this will solve the problem

Hello;
Where can I buy the same electronic tools you are using,in your video,thanks................

Hello; you still have the same problem,small screen,does not fill up.....

Smash melee fans can definitely want to find this

I wanna see what we could do with crt technology today cause processing power is so cheap nowadays, we could prob have like 8K 200hz+ crt displays

Replacing parts with better substitutions is not building a kit from Ali express.

Thanks to share your find and skills! Please you think it's possible to "connect" a Raspberry (or other similar) on it?

Well, I'm looking forward to see the update. Hopefully you can have some better geometry and no audio/video interference issues. Good luck!

You definitely have a power supply regulation problem, plus there's a hum bar going through the screen....if you had a good schematic with proper voltages it would be easy to find where the trouble is.
It's a cute little TV.... definitely check the regulation of both low and high voltage supplies.
The audio should never pull the crt pix down.
Check it out.... you may have bad electrolytics as you said.
Esr meter would check if they were good.
Best wishes.

Was this an educational kit, or a discontinued product rebranded as an educational kit?

wish their was a color one some day i hope thay will brang color crts back

I built one, the problem I have is that my image is very dull, I suspect that the HV is too low, but the raster fills the whole screen. Once I get mine going properly, I will post videos too.

"Thankfully it didn't blow up" lmao, can't wait for the follow up!

Situation of image size and sound behaviour seems to be lack of voltage issue. Feel free to contact for debuging)

I agree with others, the power supply appears weak..

I built this tv last week, and get full size image. I think your AV source is NTSC, this unit is PAL D/K, so you got a “shorter” image.

I bought one of these. Arrived with the back of the CRT smashed off thanks to bad packaging. Now I have to find a replacement CRT as I still want to build this.

Assumptions it's trash kit
