CRT Degaussing With A Drill

- Degaussing a CRT with a drill is what is done in this video. When you can't degauss a CRT enough with the internal degauss function, you can duct tape 2 neodymium magnets to a drill and degauss it as demonstrated.
You could have degaussed the monitor instantly by pulling the drill away from the monitor while spinning the drill. It is the tapering off magnetic field that degausses.
Neat trick though.
this is the kind of asmr i need in my life
As mentioned in one of the comments, using the side of a drill up to the screen worked absolute wonders! I had yellow staining on the top right of the screen when showing light colours. After using the drill method in a circular motion there is no yellow in sight! Super happy!!!
That actually worked. I am amazed
you dont need to put magnets on the end on the drill, if you hold the side of the back of the drill to the screen and spin it, the electromagnets in the drill can degauss the shadow mask too, just move the drill around the screen and gradually move it further away until its done
I just tried as you said with a cordless drill, no magnets. Worked easily. Wow!
Just tried & WOW, cleared the yellowing at the top right of the screen! To anyone looking, use the side of the drill in a circular motion backing away from the screen. Thank you so much!!!
Thank you, you saved my TV
@Paul Morley it is not a vintage set. I have a jvc AV-27F485 IArt and Sony Trinitron KD-27FS170 that I use on a daily for games.
@The Ultimate Art Bell Collection Sorry, I know this is an old comment, but CRTs are a huge deal in the retrogaming community still, as games were designed with them in mind and often look better.
UPDATE: I have since made myself a proper degassing coil, so this setup is obsolete for me personally
Can you share how you made the coil?
@@rcboosted I am not an electrician, and my product is likely grossly unsafe. I used a degaussing coil from a junked TV and followed internet guides for making the wand. I will not share here due to concerns about liability and inexperience on my part
@@wrentubes1886 Props for your second response, it is definitely dangerous to teach people how to make degaussing coils. 110V sockets and dumb internet people do not mix lol
This is the best game ever.
With the CRT and the electric drill, I can smell that.
HAHA
good job
this was actually prty cool
Glad you liked it!
Are you from that server with the train related stuff?
@@wrentubes1886 yea

Hi, did you put a magnet on tip of that drill? Ty
Yes, indeed I did. I duct taped 2 (edit: not 3) rare earth magnets to the drill, but I was very careful to secure them, so they are not visible
Thanks a lot
Cool, Anyone else here via Tedium?
Hell yeah
haha yes
Severely magnetised causes drill degaussing.
How long does this fix last?
Quite a while actually, the big thing is to keep it away from heavy sources of magentism e.g microwaves or fluroescent tubes (CFL lightbulbs are fine) and you shouldn't need to degauss it again for quite a while, anywhere from 6 months - 5 years depending on how sensitive you are to colour.
Eventually it will become a bit wonky in colour and geometry looking because the magnetic field of earth constantly wobbles and this has a slow and gradual effect on CRTs. This affects some tubes more than others, and eventually it will get to a point where you can't degauss it anymore to fix it, but this takes 20-30+ years on average and some tubes can still have a perfect picture after 40 years in some cases (usually smaller tubes where the electromagnets on the yolk aren't as affected by the inverse square law)
The only solution then is to open up the monitor and put things like convergence strips (basically ferrous magnet tape) inside, but I only recommend that for trained professionals or super nerds who know what they're doing. CRTs can literally kill you instantly and violently if you open them up and work on them without specialist knowledge or training
But definitely don't degauss like this far too often unless you know what tube you have. Certain CRTs (especially Trinitrons) have what's called an apeture grille, and that's how the tube generates colour basically. It's made of thin copper wires that can be damaged by excessive changes to their magnetic field, although this doesn't mean they're not safe to degauss. It just means you need to be cautious when you do
Personally I have a 14" JVC tube that has a shadow mask, and a 32" WEGA Trinitron with an apeture grille. The JVC tube is about 35 years old and the in-build degaussing coil keeps the convergence perfect, although I do notice the red electron gun is a bit hotter than the other electron guns, and so the image comes out slightly red (easily fixed by just adjusting the colour knob on the front)
The Trinitron is 20 years old and needed a heavy degauss when I first got it, but the geometry was perfect out of the gate (rare with WEGA Trinitrons). It's definitely the far better display, but it will need a degauss within the next year or two I reckon
About to try this on my arcade monitor 🤞🏼
Wtf is this lol
Degaussing a crt tv?If you dont know what is a CRT TV then you are maximum 12 years old
Old monitors and TV's would be affected by magnetism causing color changes and distortions ( speakers, lighting strikes, small magnets ) and would need to be demagnetized (degaussed). This is a technique of doing that with just a drill
