The act of degaussing a CRT is something I just discovered recently, and when you turned on the device I swear it looked like you were casting some kind of magic spell on the TV, lol! I've never seen anything like that, but it's so cool that magnetic fields can do stuff like that!
yeah first time I saw this and did this it was really surprising. I learned to work on TV's, cameras, etc in the Air Force as a broadcast engineer for their overseas TV stations (AFN), going through school this was one of the many things we needed to learn.
@@CraigKergald That's pretty interesting! My grandpa was also in the Air Force and he told me that he was a technician person who worked on computers, TVs, and electronics, I'm not fully sure what exactly he did but I know he was more of a tech guy which is always fun and cool to see!
very cool, while we did have career fields there was some overlap and opportunities to work outside out field based on need and skill. My field did not cross over into computers however our IT shop was severely understaffed, we were overstaffed and the right people discovered I had the skills and interest in working on computers, networks, servers, etc. This was in the late 1990's I'm not certain the same would be true today.
I wish CRTS stuck around because of the way it would produce 15.xxKhz tone. As you age, the frequency range decreases (I'm around 17Khz). one day not being able to hear that sound anymore just reminds you of old age
I remember it being pronounced, but people always were confused when I mentioned "the sound of a TV turning on" because they couldn't hear it. Kids now think I mean a jingle
LOL, the worst was when someone that couldn't hear it would leave the TV on but with no input so just a black picture. I was always like why did you leave it on, and they were always how did you know it was on ?
@@CraigKergaldreminds me of when I was a kid. My dad liked to watch horror movies after us kids went to bed, and I remember waking up to that ping, sometime after my dad would turn in. I'd have to sneak downstairs to go shut the TV off to get back to sleep
I was a child right at the tail end of the CRT era so I do know about CRT displays, but recently I've seen a lot of videos on RUclips of people using the degauss feature built in on most CRT monitors and TVs, but none of the videos actually show the discolouration and the actual reason you'd need to degauss the display in the first place so I didn't know why. So I have to give a big thank you for making this video and actually showing the reason you'd need to degauss.
When I was young we couldn't afford a nice new CRT T.V. and often found ones being thrown away by neighbors, usually because the colour was off. This would have been great because smacking the TV never really fixed the issue and waving a magnet infront of the TV usually resulted in looking for another TV being thrown away.
i found this video while trying yo research what degaussing is actually doing, and if anything i am only more confused now but it was still cool as hell
sorry, never really expected this video to get anywhere near the number of views it received I will probably re-do this video in the near future as it was one of my first and can be improved greatly.
I had a monitor with degaussing built in as a kid and i just didn't know what was it for. I just did it for fun bcoz it made funny patterns on the screen. :)
this is unbelievably awesome! next time you degauss, would you be able to get a clean recording of the screen? i would love to see different test screens degaussed and geometry adjusted
I'll try, it will have to be captured by camera as the actual video signal going into the screen is not manipulated in any way it would just be a standard test pattern.
I had an old viewsonic that I manually had to degauss with a huge magnet. It had colored sections in 2 corners. The built in degauss didn't fix it but that magnet sure did.
This is cool I remember being in computer class as a kid and going around and pressing all the monitors to make the cool sound and see the screen do whatever it did I had no idea why it was doing that
I really like your videos easy and simple not to much speech, is that happen with every TV? Crt ? Can u give me the link to buy this tool appreciate your help and educate for us 🙏
All CRT's will experience this color shift issue with changes in magnetic fields around them, however many consumer TV's have built in degaussing circuitry already. This arcade monitor in a TV housing does not. This is very similar to what I am using - www.amazon.com/Waldom-Degaussing-Coil-Color-Power/dp/B00011UYJU/ref=sr_1_3?keywords=degaussing+coil&qid=1691578633&sprefix=degaussin%2Caps%2C89&sr=8-3
I grew up with those CRT and TV screens. But never had a thought of degaussing, or setting the geometry right... But today I wondered, how the beam just hits the right colors, if you adjust the geometry of the screen... Wouldnt that have to happen in steps, as the colored dots are also arranged pixelwhise? Or do i remember that wrong?
The colored dots are not really pixels but they are phosphors that the electron beam lights up. Degaussing just corrects the magnetic field on the screen so the correct phosphors are lit up when the electron beam scans across them. The geometry adjusts this size and shape of the image on screen but will not effect which colors are illuminated.
Huh, so that's where Duskers got its degaussing screen shader effect from. I always thought it was a rather odd screen effect anytime you ran the degauss command in the terminal.
the beam that draws an image on the screen is steered around that screen using electro magnets, when you rotate the screen the natural magnetic forces (earth's) orientation changes slightly causing the beams to be slightly mis-aligned. a regular TV has a built in degauss function that would take care of this but my monitor does not. This could also happen if just moving the monitor around from one location to another at my home though not normally as pronounced.
this is an arcade monitor and has knobs (pots) used to adjust these settings. if your image is slightly rotated your yoke is probably rotated (the big magnetic coils on the back of the tube) Once you get that fixed you will need to look up a service manual for your model TV to see if you can adjust the image size further.
Easy and dangerous aren't mutually exclusive, if your yoke is loose its not that difficult to fix but you will be working around high voltage, you should either find someone comfortable with it or at least do some research on CRT yoke adjustments before getting started
Why wouldn't an arcade machine use de-gaussing? I don't know about TVs, but I remember that computer monitors would either do it when you turned it on and/or when you selected to do it manually
I'm sure costs were a reason for some manufactures including mine who made this generic arcade chassis (circuit board). For others it may of been a design oversight, or because the monitors ran all day every day without really being moved in cabinets.
While this looks like a TV its really an arcade monitor placed inside of a TV housing, the back is open and has the regular knobs/pots you use to adjust a arcade monitor. I'm just turning those to make these adjustments.
That tv looks just like my parents old tv, that thing could sit in the rain for 3 days and still work. You could pour hot chocolate down it and it would still work.
Some of the later CRTs before everybody switched to flatpanels had an option built into the monitor itself to degaus. I never really understood why it was there because I never seemed to need it.
degaussing will probably help, Sony TV's should have a basic built in degauss feature. I'd recommend unplugging power from the TV let it sit for 30-60 minutes then plug the power back in, when you first turn it on it should energize that degauss circuit for a moment which is hopefully enough to straighten out your colors, if not you might need to get something like this tool I use.
@@CraigKergald ya I have tryed to see if it would automatically do it, I can't get the feature to work & sadly degaussing rings like that cost an arm & a leg

thanks Craig. I'm dealing with this issue right now. It's NOISY x 100
Thanks for the message, you may want to check out the updated version of this video, this one was made early on with a poor quality mic.
From looking at this I can actually smell the pungent odor of ozone comming from the CRT. Like it was yesterday.
I had an old viewsonic that I manually had to degauss with a huge magnet. It had colored sections in 2 corners. The built in degauss didn't fix it but that magnet sure did.
I've never had luck with just a normal magnet but thats cool if it worked for you.
This has a criminal lack of views. This vid is amazing.

So if I need to regauss my monitor I can just rotate it a few times? Or is it better to leave it on it's side for a while?
Awesome! I got the 1000th like! XD
Also, this is a cool demonstration!
some years ago my grandpa told me this. i didnt believe him. I guess i can fix my Old Tv Now.

Huh, so that's where Duskers got its degaussing screen shader effect from. I always thought it was a rather odd screen effect anytime you ran the degauss command in the terminal.
He just exorcised a tv
So why does rotating the screen cause this in the first place?

this is awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

How were you adjusting the geometry like that? My TVs picture is slightly rotated as well as doesn't fill to the edges of the screen 100%.
this is an arcade monitor and has knobs (pots) used to adjust these settings. if your image is slightly rotated your yoke is probably rotated (the big magnetic coils on the back of the tube) Once you get that fixed you will need to look up a service manual for your model TV to see if you can adjust the image size further.
