The coils of the yoke are not are shock hazard unless they are damaged, in which case you'd have more issues than just a wonky image. While making sure there isn't any damage to the insulation before messing with it is a very good idea, under normal circumstances, you aren't going to get shocked from the windings themselves. The wires are all coated in an enamel coating to prevent any electricity from shorting between separate runs of the same length of wire. The exposed posts on top of the yoke however, if not covered, can potentially be a shock hazard. That said, from an editing and photography point of view, a great step up from previous videos.
Just did my first CRT adjustment thanks to your channel and this video :)! pretty happy with the outcome. Thanks for putting this information out there.
attempting to adjust the crooked image on my Toshiba CZ32 model! Just unscrewed the back of the tv and came to watch again for last second refresher. Thanks again!!
Following the illustrations here, I was able to straighten Apple IIc monitor. It's a monochrome, so fewer rings and one tightening screw. Thank you for the tutorial!
Awesome video. Just found an old TV in the attic of the house I just moved into. It has a slight tilt and edge discoloration. Going to familiarize myself with safety steps before tearing it apart.
Thankyou for this video, there aren't many i could find to explain this. I am attempting to fix/restore an arcade machine where the picture is shifted down 1/4 of the screen and tilted left. It's a really beat up machine and seems like it's been literally dropped off the back of a truck in an unloading mishap or something.
Awesome info. I recently acquired a Sanyo that is suffering from some pretty severe purity / convergence errors and will be trying to adjust it this weekend
Retro Tech I agree. Great clean editing and the different angles really help illustrate the way the yoke positioning works. Obviously more work but really adds to the quality. Any chance you’d make a $1 tier for those with tight budgets, but really appreciate the work you’re doing?
I have an arcade monitor with a broken yoke. Its just dangling there. I'm fairly new to actually working on them but I was able to temporarily hold the yoke in place with Gorilla tape. I felt like a huge wuss for ordering those same gloves, until I saw you wearing them haha. I'm not interested in getting a nice shock! I'll be wearing those to make further adjustments.
This is some quality content in both information provided and how it's presentation. Well lit, subject actually clearly in frame, and no talking butt video (presenter between subject and camera). Subscribed!
Good day Sir Thank you very much for creating these CRT videos; I have learnt a lot so far. When adjusting the yoke position while the tv is powered, what gloves should be used? Any rubber glove or is there a special requirement? I understand that the voltage on the horizontal deflection coil is quite high. Also, to correct for screen tilting, can a small rotation of the yoke cause the purity/convergence to change? Thank you very much. Regards from South Africa
Great video! I'm a huge fan of your work! I'm in New England but hope to be able to hire you to fix my PVM someday! It's so hard to find someone trustworthy that works on these old TV's! Thank you!
Brilliant! It's a mess, that Germany and the states are so far away from each other. I have at least one TV here, which would be a perfect try to repair, as it seems to be related to the same issue.
Hi the convergence magnets are usually marked on the fingers, P = purity, 4 = 4 pole magnet for red/blue convergence, 6 = 6 pole magnet for green/magenta convergence, The enameled wire you can see on the outside is for the vertical scan and as such is generally low voltage so even if the enamel is nicked will not pose a shock hazard. Please be careful of the red/blue lead terminations they will make you jump, usually not a terminal shock hazard but if your heart is not up to scratch or you have a pacemaker I can not say for sure. Where the rubber bumpers are you can see some light coloured strips that are stuck to the CRT these are magnets stuck on the end of a strip of card/plastic and are to micro adjust the convergence in the corners.
Hmm... My arcade monitor does have some solid purple in the far bottom right corner of the screen. Even when I got the monitor new I always had issues with screen geometry looking straight on one side of the screen but warped on the other. Maybe a simple Yoke adjustment will help a lot. The monitor came with no cover to begin with. Definitely picking up some antistatic gloves though.
Hi, I want to start off by saying I love your content!! I've learned a lot from your videos. I have a Panasonic 27" super flat, model CT-27SF35W manufactured in 1998. My image has a tilt to it and some corner convergence issues. I was told awhile back that this set has a fixed yoke so no adjustments can be made by a TV repair shop back in 2015. I was just wondering if this is true? I'm a little intimidated to try to straighten it myself, but the TV is in such nice condition I'd like to have it corrected. Any advice and information would be appreciated, thank you!!
@@RetroTechUSA Yeah I have a 21 inch Trinitron that I'm sure had the yoke a bit out of whack, assume it's been dropped, top two corners are wonky. I'll see if I can straighten it up. The safety videos have been great. Already helped me get a few sets adjusted without drama. Still a bit scary but I'm being ultra careful
Fixing yoke tilt is fine and quite easy to do but how do we reseat a yoke properly so that convergence and geometry is equal across the screen? Just adjusting the tilt can cause these problems to develop too. I'm using spirit levels and all sorts to try to get it right and there is always a new problem somwhere on the screen even when I think I have got it right. I'd like to come across a more solid solution to yoke sag instead of the Y ring magnets as that acts more like a bandaid.
Something I've always wondered about is: can you adjust picture size (overscan) using the yoke by moving it? Reason being, I noticed on many if not all cheap modern CRT TVs there is no way of adjusting H-Size in the service menu (only V-Size), just the higher end sets seem to have a H-Size option for whatever reason, and there are no pots on the chassis either. But there must be some way to adjust it, so the yoke comes to my mind.
I got the same problem only I see H Size in my service menu, it just doesnt do anything when I change it. he said if I recapped the TV Id be able to adjust it. not sure if thats just with the PVMs though since I have a consumer grade CRT
@@dudeguy7347 Yeah, it's the same on my cheap 2005 consumer CRT TV. There is a H-SIZE option in the service menu but, like many other settings in the service menu, it doesn't seem to be tied to anything and nothing happens. Recapping definitely won't help that. So how was the horizontal picture size set in the factory? Maybe it's fixed to some predetermined value by some cap or resistor and simply isn't meant to be adjustable at all to make the manufacturing process cheaper?
@@martinweizenacker7129 if you figure out how to adjust it please email me because I have a 2005 CRT as well and the overscan drives me crazy. paulmccabe3@aol.com
just discovered your channel, great info.... do you have a video on horizontal not being centered... this tv i have is a portable 9inch ktv, there's no pot to adjust position... picture is pushed to the right
Would you recommend adjusting the yoke on a Sony Trinitron KV-36FS120? My screen tilted the other day and the tilt screen correction setting leaves black lines on the edges.
Great vid!btw,can you tell me how to fix my CRT TV screen stop moving on video mode?even when entering the menu it appears like moving (not instantly like it's meant to be) and when playing games (PlayStation or PlayStation 2) when the screen transitions or changes (when it goes black and another one comes up,for example) it fades away or appear very slowly and moves towards the screen like in a 3D effect,it never stands fixed when there any kind of movement on screen and it's like autofixing itself depending on what's on screen.It's very odd,I can't give any more details about it.It all started when I gave the TV to some "service" just for them to center the screen (horizontally and vertically),now I have a useless TV...any kind of information about this is mostly appreciated!
I'm pretty sure I need to push my yoke a little forward, as I have some purity issues to work out. However, even when loosening the yoke screw (this is a PVM-8045q), the yoke won't budge! Any tips on getting it loose enough so that I can move it?
Thanks. I just fixed my badly tilted TV with this vid (and the CRT safety one). I just wonder how to fix Horizontal linearity as 240p Sonic stage looks bad.
@@matcarfer that'll be it then. The flats aren't too accurate for light guns either. If you have something you can run 240p test suite on, the patterns in that will illustrate the downfall of removing the curviness from our screens
Not sure where to ask this, but would you happen to know what to do about a horizontal deflection cord that should be reading at .5 ohms but is reading between .2~.4 ohms instead? I made a thread in an arcade forum trying to troubleshoot problems with a chassis not staying on and arrived at the point where this might be the reason (stays on with the horizontal cord and vertical cord unplugged. The vertical is reading correctly between 6~7 ohms though), but I'm kind of stuck here.
He's using a program called the 240p Test Suite. The grid pattern is taken from a CPS-2 arcade ROM's diagnostics mode. Your best bet is to put it on a Wii running homebrew since the Wii version is a free download, or you can buy a cartridge/disc with the program running on it if you have a Sega Genesis, a SNES, or a Playstation 1/2; hell there is even a HUDcard if all you have is a Turbografx-16. junkerhq.net/240p/
I have a Sony Trinitron 1370R, its slightly tilted to the right. All I need to do is loosen the screws on the yoke, slightly turn it to the left and I should be good?
should I do this to counter the earths magnetic tilt? I moved houses and where the crt is now its tilted and is perfect if I spin the crt to north but I cant have the tv stay that direciton to use
Retro Tech did all that I can afford right now btw do you own a kvXXfv310s I have a 36in I've been trying to mod can't find any info that's free or doesn't spam me
I've got a large Panasonic consumer CRT from the late 90's. The picture doesn't make it all the way to the horizontal edges of the screen. (Vertical is fine). I have found a pot inside that controls horizontal size, but even with it maxed out it still doesn't reach the edges (and overscan is visible). Can this be corrected with some kind of yoke adjustment?
@@anthonyterry8162 I wound up trashing that set and replacing it with another (free) one I found. Most likely it would have needed internal work such as capacitor replacement, etc. which I can't do.

Hello! Does anybody has an idea how this works with a B&O MX4000? I could get it to look good but it always goes back to it's crooked position. There aren't much Infos out there and at first I thought the problem are the wedges. But i was reading on a forum, that the yoke and the tube are one unit on these and you can't adjust the yoke at all. Is that true?

I called a TV technician today and told her about the problem and the possible fix, she said that yoke and tube are one unit on B&O TVs which makes the yoke unadjustable. Is that true?
Sort of true. PIL (Precision In Line) CRTs (pretty much all colour CRTs from the mid 70s onwards) rely on the position of the yoke for the convergence. Once these have been set up, they’re often wedged, glued and fixed into place. I have the same issue on a Hitachi set. I’ve looked into trying to fix the issue, but I don’t want to mess the set up. Try getting your inputs to display in fullscreen, and not in “letterbox mode” where you get black bars, this is where i notice the tilt. Fullscreen isn’t so bad.
Hey, I've a Commodore 1701 monitor and it's a kinda cool monitor, everything works well about it, the only problem is the image a bit tilted. After viewing this video, it's clear the yoke probably moved a bit in it's life. It doesn't seems hard to fix it, the only thing is i'm very afraid to received an electric shock. I checked your channel to find some safety tutorials but i didn't find any :/. Do you have some easy to follow tutorials I could watch or read :) ? As i'm a totally new to this, working on it while plugged seems very dangerous for me, if I let it unplugged for a week will it be totally safe to try moving the yoke ? Your content is very cool and helpful anyways, thanks for that ! EDIT : I just foud your video that explain how to do it : th-cam.com/video/d1mQupQHFkc/w-d-xo.html. I'm still affraid with the discharging step though.
Presumably also a metal wrist strap at wrist not sleeve of person is protection against the power should it suddenly try to go to said person the power should go to that hand then strap an not the heart... also the other hand without strap presumably would be always behind back... to avoid touching anything inadvertently idk... just assuming don't actually listen to this I've never serviced a tv just studied the,.. lol
