Thanks man I subbed back! Some of this stuff seems like a hidden or lost knowledge so when I learn it I try to explain it in an easy to digest type of way. Vids like this arent very entertaining or popular but for me id rather help a handfull than entertain a million.

@@LameGaming exactly, as soon as I figured out how to get into the service mode of a Sony Trinitron I posted a video. Then after that I made a video on how to calibrate your TV using the 240p test suit. If we don't preserve this knowledge, crt televisions will slowly die away. Have you seen where that guy is making a open source mother board for replacement on any model crt. As long as the tube is fine, you can use his board to operate it.

@@JoeRetroWorld Exactly! Your talking about the open source crt project?... Yeah it sounds pretty damn cool and sounds like you could create a pvm out of a consumer tube as long as the tube is quality. But yeah I watched the interviews retroRGB bob and zezretro had with the guy.... Hopefully it gets completed and kits wont cost a fortune. I know another guy electronash who is building a test bed for it, he helped me disable my TV tuner signals from reaching the integrated micon/jungle chip on my sony 27fs120.

@@LameGaming fixed!! Happy now?? Lol

@@Undar8ed03 👍🤣

Its hard to find anyone to fix these things, thats why I started working on them myself. Hope you figure out your convergence problem.

@@LameGaming Hi. So tried to fix it but there is a problem. No convergence rings XD. I found focus and clarity potentiometers but no rings. The only thing near tube I can mess with looks like potentiometer but no idea really. Its a barrel with allen screw inside. No idea if thats safe to mess with.

Thanks, I should of mentioned some non sony consumer sets might have 2 pairs of purity rings and some later sonys had an extra set of rings for H bowing way out on the neck but I think most people will know what they have.

I really appreciate it! The editing is alot of work and I dont get much of a following but if it helps even a small amount of people ill continue. Thanks for the feedback!

That sucks, sorry man =(

I have a few 40 series pvms with dim tubes and did alot of digging as well about rejuvenating sony tubes and kind of found the same info as you..... Nothing definitive. I was going to pick up a rejuvenator and see how it went. I read something about sonys needing each color rejuved seperately but dont remember the details now or the validity of that info. Sadly im working 60-70 hours a week and so dont have any free time at the moment. I had a ton of footage for several videos but dont even have time to edit any of it 😒 Hopefully i can get some free time in the near future. Thanks for watching!

Ive only ever owned a couple arcade monitors and that was before I started messing with crts but I would assume a yoke adjustment is only necessary if your image is tilted, you have yoke sag, or you know it needs reseated. alot of the time some edge and corner convergence issues are just part of the hobby, no crt image is truly perfect. If its just that one corner, maybe try a magnet first. Honestly...the little zap I got startled me more than anything and its the flinching reflex that will damage your crt or yourself lol. I dont know if the glove helped, I have a lineman glove rated for this stuff but you have to put another glove over it and it is too bulky to use. I always try to keep one hand behind my back and stay away from the anode and power supply and have been fine thus far but dont do as me just because I do lol. I havnt had to do any yoke or ring adjustments since messing with these 40 series pvms but have a 2030 and 2530 im going to recap soon which im sure will need some tweaking.

Sorry, Im in the midwest. I currently have a couple m2u's on the bench Im working on.... One with sync issues after recap and the other still needing a recap. If I have time and need to dial in convergence on them maybe ill make a vid but cant promise anything since free time is almost non existent with my job 😟

@@LameGaming I feel that man, best of luck with those! Would love to see a video if you post one. The 20M4U has a very unique yoke and there do not appear to be any videos on it out there.

@@GodfatherNick17 I think the only major difference between the m2u and m4u's were that the m4's have 800tvl count tubes. I know my service manual covers all the 14 and 20" m2u's , m4u's, and medical variants so the yokes should be the same. I agree, the yokes are very complex looking. I think convergence adjustments are made in the service menu are they not? I might remember seeing a single hstat pot on the neckboard but cant remember if there was rings for convergence or it was controlled by that fancy electro doohicky on the neck lol. Im not at home and have both monitors stripped. Ill play with it when they are together but could be a while unfortunately

Lol, It did eventually come and tested the mvs a bit and put it on the console shelf for a bit. I have a bunch of these pvm's im working on, and an rgb mod, and leaving tomorrow to pickup some more displays but plan to revisit the neo geo bios mod again soon. Mines just a clone, i dont think it has the vmc, i thought about hardwiring in a dedicated socket but havnt decided yet.

@@LameGaming that's cool that you got your controller from Japan delivered. I've been thinking about getting it neo Geo mvs console by watching these videos. Looking forward to part 3 after you're finished with the pvm mods and rgb's

Thanks... Its Contra Hard Corps on Genesis

No idea, i dont have one. Sorry

I dont own an iart but have a jvc 36" curved tube crt that I just rgb modded. I dont think it has an hstat knob either. Probably all done with the rings which may be glued down. My yoke is bonded to the tube as well, not sure about the iart sets.

@@LameGaming Opened it up yesterday and there's no way to move the rings. Probably glued down and I did not want to mess with it since I'm new to CRTs

@@makojuicer Probably a good decision, crts are never perfect due to the nature of the technology. Sometimes a little misconvergence is to be expected, especially towards the corners. I have 3 sony pvms that all had new tubes put in but the serviceman never bothered adding convergence strips. I got the majority of the screen converged well but theres some misconvergence in the corners. I have two options, spend a whole day moving around convergence strips to find the best location and gluing them in place and let my ocd make the whole process 10x longer than it should take.... Or ignore it which you really cant see unless your looking for it anyway. Im ignoring it..... ...For now 🤣
