From what I know about colors on a CRT TV, you have to adjust the R,G and B beams by rotating rings somewhere before the coils on the tube. By doing so, you will direct the beams on the R, G and B little spots on the screen (yes, look at it very closely : one single dot is in fact a combination of 3 dots : a red dot, a green dot and a blue dot). Be patient because it is quite difficult to tune it properly. I remember having destroyed the image of a CRT TV that could no longer be other color than grey... before I understood I've touched the 3 rings... ;-)
Great video! I’m no expert but maybe there’s a way to alter the screen in front of the crt. Supposedly there’s some phosphor layer or mask that can be removed. Other than that the other possibility is maybe controlling the electron beams with magnets 🧲 to alter the color. I’m going to try this myself and see what I come up with.
Dude I’m trying this right now and it is not working. I connected the yellow and blue to one rca Jack and same for the green and red but the laser isn’t showing whenever I connect everything
If you have imbalance in between your left and right channel (such as the songs that they apply effects that pan the music or even vocals) you will have issues with your scope measurements. Excellent work though! I have done this successfully a couple times myself. The red may be due to the coils not being connected to the driver (the pc in your tv itself). The driver knows this and maybe only activatimg the red electron gun.
No claim here that I know anything, but, you might want to measure the resistance of those defection coils and use those values for resistors on the board where you disconnected them. Basically you left that circuit open with no load, if that is sensed it might effect the colour. I'm scared of CRT's myself, might have something to do with me pouring a vase of water into a b/w TV as Dad was asleep watching a movie when I was a kid, or was it the TV repair man shouting at me when I started poking the circuit board with a metal dinner knife?, might have been double trauma.

Boan I used an A/B box and connected a 1/4in to an old bass amp i had for audio but you can connect it to something like a Zoom if you want to record the audio. But yeah google AB Box, really helps for this project
The red color is either the other guns are turned down or inoperative. If inoperative, I would look for bad grounds in the other two color circuits. Have fun as this stuff is
Love this! Tried this today and followed your tutorial. But since I don't have an Amplifier I used an Aux Cable and connected the left channel with the vertical coils and the right with the horizontal coils. Unfortunately I couldn't really get this working because I just got a straight line on the screen. Do you have idea what could be wrong?
thanks for the great video! I want to make one of these, but my amplifier only has a pair of speaker outputs :/ would it be possible to daisy chain the speakers and tv wires without affecting the amp? thanks :)
Man i had one of those third hand deals u used for soldering but i fuckin took a 5lb sledge to it because it wouldnt stand up for shit.. lol i got anger issues..
ok so after you solder the wires to the audio input on the back of the tv I got a little lost... how were you able to plug into the amp from your laptop?? I really want to make this a summer project
Ok, dope. I made a cable using speaker wire, one side is an RCA jack - the other is bare speaker wire, because it's hooked up to a hi fi amplifier. So Computer - Interface - HiFi Amp - TV
You could probably do a video just showing that circle and people would watch it. Something is mesmerizing about that!!! ALL HAIL HYPNOTOAD!!!!!
I might do just this. I am thinking about playing tunes through it for fun.
@@GARDNSOUND What tones did you use to generate the spinning ring? Also, I actually really like the red!
oh you dirty bastard.....I actually jumped at the explosion
Killer video man. That fucking color on the tv is the shit. Hoping to do one of these myself soon.
I know im a little late but i really enjoyed this Video. I am collecting tiny CRT tvs (5 inch and smaller)

that explosion scared the shit out of me! just installed a new sub lol
hahahaha, yes!!
I love this type of stuff... especially the visusls at the end .. super trippy
Thanks!
This is literally the coolest thing I've ever fucking see.
Do more!
I would, but this video's not doing well :-/
Hard to justify the time, LOL! Had fun though :)
GARDNSOUND well that's all that matters in the end right? :D
There is a Brazilian channel where the owner made one of those with double channel! his name is Rodrigo Negrelli
I've worked with some cool electronic stuff before but that, that is cool.
Congratulations, beautiful work, I'm also building one ... Greetings from Brazil!
Have you heard of Jerobeam Fenderson? He makes music that is designed to be played through this type of display. It's pretty neat to look at!
I actually have through researching this hack!
can’t wait for the teevee mcteeverson mixtape
omg hahaha
I love this, you should make this a series
So the next step is to incorporate this in a music video therefore giving it ur gardnsound aesthetic 👍

The return of protection eyeware! Except with D O U B L E P R O T E C T I O N
This was really cool by the way. ^^
Great video! I have a LCD VGA PC screen (specifically the AOC LM725, it is a 2005 screen, not a tube screen). Can I do the same experiment with it?
You should be able to, and it will actually be better suited as the front lead plates can better handle the focused radiation this mod creates

Yo! @LookMumNoComputer inspired this video lol
How do you get audio too? The output of the signal > amp > rcas going to the crt. What’s connecting to the speakers
Boan I used an A/B box and connected a 1/4in to an old bass amp i had for audio but you can connect it to something like a Zoom if you want to record the audio. But yeah google AB Box, really helps for this project
I dont know what you should call it but it certainly not an oscilloscope.
Fun video me like
yaaaaaaaaas
thanks man!

Yeah it sounds like you've only got one axis firing. But, I'm way too new at hacking TVs to provide any solid advice :(
dope
thanks for the great video! I want to make one of these, but my amplifier only has a pair of speaker outputs :/ would it be possible to daisy chain the speakers and tv wires without affecting the amp? thanks :)
definitely. the signal coming from the amp is attenuated to work for both. you might see a drop in volatage, but you can just turn the amp up more.
cheers for the response!

I have an audio interface routing two separate audio signals. One left and one right. They must be separate to achieve this effect!
GARDNSOUND I've got a steinberg ur44 as an interface, I'm just wondering what you do in order to plugin/make a cable to/for the tv
Ok, dope. I made a cable using speaker wire, one side is an RCA jack - the other is bare speaker wire, because it's hooked up to a hi fi amplifier.
So Computer - Interface - HiFi Amp - TV
GARDNSOUND OK cool so basically the rca cable is stripped away then gets directly looped around/joined with the vertical and horizontal crt wires?
You're the man for walking me through this 🙌
Is it possible to submit 2 songs for the next coffee time?
this is not THE OSİLOSCOPE !!!
Do more diy music stuff
Lol tv mc teeverson
What color is syanne?
I'm sorry, I'm a smartass.
Cyan. It’s a light blue.
Jesus christ bro....5 seconds into your video and ADs
