How to degauss, rejuve, & restore an arcade monitor. Sencore CR7000. Bondo. Gyruss Restore Part 4

[@leewhicker3540]

Also have taken johns advice and jumped head first into the hobby. Got like 10 games in 3 months. So much work to do. Already done a yoke swap, caps, side art, flyback,ect.

[@Phaegian]

This Gyruss project has been one of my favorite things you've done! Keep up the good work!

[@arcadeimpossible]

Amazing John! I never new about the rejuvenator tool. Very cool.

[@dinkyflix]

If you can't afford a CR7000, the CR70 works great as well as is usually a lot cheaper. I love mine and have used it a ton. These tools are a must for anyone serious about arcade stuff. By the way, love the videos and what you do for the community, John.

[@capnarrr]

What functionality do you lose with the CR70 as opposed to the CR7000?

[@dinkyflix]

capnarrr As far as I know, just the LED bars. You also have a few more knobs you need to set. They both function the same and do the same thing.

[@martinda7446]

You evenly rotate degauss tool whilst moving away from tube. Those speakers look like they are not shielded too.

[@w0mblemania]

Fantastic videos John. Thanks heaps for going through all these steps on video for us. Really helpful.

[@dn.sw.explorer]

That looks amazing john, nice bit of test equipment. Think it looks much better after.

[@MagikGimp]

Even thought the old picture had burn-in I had a feeling it didn't look as good as the new one, and I could tell that through only a video taken of it. Always fascinating watching you do this stuff John, rather you than me though if I'm honest! I mean I'd love to own cabs myself but it's a huge undertaking once you get into it; you've caused me to realise that! ;)

[@artijl]

Great video John. I'm really enjoying this series.

[@hitmanhite]

Awesome vid man. After a while, every time I heard Texas Chainsaw Massacre in the background, I would just chuckle.

[@jamesrbrindle]

Wicked video mate! Try turning your degauss coil through 90 degrees to change the field slightly to get rid of that stubborn magnetised bit. Do very quick bursts too rather than sustained. Your deg circuit could need looking at, just shot a vid on Sunday on this.

[@StevesRealWorld]

Great Video Jon, now I want a rejuvenator too!

[@AiMR]

Black Formica in that panel where the coin door sits FTW and save lotsa time & effort.

[@RejectedManiac]

Not to nitpick or anything but when doing any rejuvenating with the CR7000 you should always start at the lowest setting and step your way up. It says it in the manual too. Good videos.

[@inachu]

Super cool to watch this video but I'm happy that many arcade refurb places are just starting to use LCD instead.

[@Johnsarcade]

+Inachu Ikimasho LCDs blow. Sorry, just not the same.

[@inachu]

John's Arcade Game Reviews & Tech You tried it?

[@Johnsarcade]

I have played games with LCD displays. It is just not the same. Not even close. Fix the old monitors and make them survive. Don't trash fixable old stuff because it's easier to throw an LCD in.

[@inachu]

John's Arcade Game Reviews & Tech Well I mean yes perhaps to get that OLD SCHOOL vibe back. Do you which tubes were/are the best back then that you run into?

[@Johnsarcade]

Inachu Ikimasho Best monitors are the WG 4900 and Sanyo 20EZ. Then G07, K7000

[@Johnsarcade]

I'd like to go and I have thought about going in the past. Not sure! It's always during a busy part of the year for me!

[@MikeGervasi]

This was opposite to what I've seen with mine and Turbo's. We usually get low tracking but ignore that (usually 3 knobs end up full) and then emission readings are so-so. Hit the guns a few times and the tracking still sucks but the emission levels are all 3/4+ Reinstall and monitor is much improved.

[@123allrock]

Most monitors have small corrective stick on magnets to correct color purity issues if you replace a tube these wont be there or will be in the wrong place if one is careful not to shock ones self , you can use a weak refrigerator magnet or magnets on the back of the tube to fix color purity issues, First, you need some thin flexible magnet material. Not too strong, typically fridge magnet strength. A strip of flexible magnet can be purchaed in Home Depot or a craft section used for making picture frames etc. The idea here is to use the magnets on the back side of the monitor to compensate for the area that is not pure. Experiement by moving the magnet along the back side of the glass tube. The closer to the center (yoke), the more compensation. Turn and spin the magnet until the blotch goes away and then glue the magnet in place. You may see other magnets already glued in place by the factory. Use that as a guide for size and location. Again - do this with the monitor OFF and wait 15 minutes between each attempt so that high voltage is discharged. Do all adjustments to the monitor in the position where the game will reside or you’ll be chasing your tail.

[@Johnsarcade]

I like this idea! I'll look into it!

[@bamaslamma1003]

Is the CRT in a video game the same type of CRT you find in a TV set?

[@TheRabidfox11]

Great vid. John ..Great to see and learn about new interesting equipment. Also thanks for the info on the SEGA cab. That guy in Lacrosse so needs to get rid of it. He keeps coming down on his initial price. The Sega cab. alone may be worth 200. NOT SURE? But i guess i like all original. Thats Just me ,kinda weird that way. LONG LIVE ARCADES!! Peace out!! p.s plan to check out your podcast 2morrownite

[@classic2181]

John, after watching you mix the bondo, I want to see a cooking episode haha

[@Johnsarcade]

Yeah, that thing is crazy! I was actually a little worried about my video camera. :)

[@MagikGimp]

I'd say there's an improvement in the picture; my point was that I thought you put the red up too high or that it was the green gun that was failing the test. Of course you should trust your own eyes over what your camera was recording though. Interesting tip comment from a Mr James Brindle I've just read, might what he says help?

[@wmccluskey]

Great video. Have you tried using a Go-Pro, or similar to let you shoot hands-free? Also, do you use a microphone? The voice over comes through extremely clear.

[@Johnsarcade]

I had a Go-Pro, it's cool. I find the fish-eye lens to be a bit much. I am using the built-in mic on my camera.

[@cavanaughaz]

Hey John. Can you PLEASE help me with which Sencore model I should buy? I can't find the same model you have, but I want to make sure I get one that works the same and also has the rejuvenator option as opposed to just a tester. I also like the LED indicators on yours. Thanks in advance man! You're the best!

[@EdoJp]

Are you going to California xtreme? Hope to see you there John

[@SummerFunMan]

Great episode! I had not known that this tube-rejuvination tool ever existed, and it's cool that it has sockets that match rather than having to use alligator clips, heheh. But you know, I wish you would revisit this because I was hoping to see that you would show us video of what's happening *on* the front of the tube while you were doing this! Will you do that for us, please? Would we see *anything* on it without the anode cup hooked up? Have you ever looked at the screen while doing it? Will you try it one with the cup still attached? Happy Thanksgiving!

[@Johnsarcade]

Are you saying the new picture tube didn't look as good as the old one? I think it does, no? Working on this stuff isn't too hard, it's kind of fun if you ask me! :)

[@davidtheswedishtechguy]

when i was younger i fixed my Panasonic tv with just a big magnet and massage the picture and it worked😊 i got det problem when i moved my speakers around and got to close to the tv, cuse i hade big speakers it meesed up the pic

[@leewhicker3540]

I got a cr7000 and I have a couple tubes that are dim. I have followed the instructions in the manual but have seen strange results with the low cut off test. When I do that test none of the bars move. Did gentle restores and the tubes look better but the low cut off tests still show nothing. Wonder if something is wrong with my cr7000 that is making the test report no reading? I can still return it as I just got it.

[@Johnsarcade]

I got mine on ebay. It's a popular model. Shouldn't be hard to find!

[@filter4now]

Damn, I didn't know I had a twin brother. You look EXACTLY like me, like working on video games, etc.

[@MxArgent]

I was sort of wondering whether or not one of those rings can moonlight as a bulk floppy disk eraser...but nope, they might not be strong enough. Darn.

[@localfigaction]

Where did you get your leg levelers? Those look nice!

[@mattcooper7275]

Re: the paint. You can put oil based paint on top of acrylic based paint but you can't put acrylic on top of oil.

[@Bobaflott]

Hey John, have you ever seen a Fonz arcade game? It was made by Sega in 1976. It isn't emulated in Mame, because there no roms or cpu. Looks really cool in klov though.

[@jokton]

Yah, where can I get some teflon base leg levelers?? I've been wanting something like that for a while

[@jimcraig6142]

Hey John, does this help with burn-in? Or do you have a method besides feeding snow to take care of burn-in?

[@Johnsarcade]

There is no cure for burn, unfortunately.

[@Johnsarcade]

Wow! Thanks! :)

[@jupreindeer]

I had that very same thought. Then, quickly ditched it, in fear that the footage would be "sea sickening". A tripod is far superior, even if a bit more troublesome, when your hands are full.

[@GuardYourFlanks]

I have a monitor that seems to have lost the red all together. Would this Sencore CR7000 be able to bring that red back into the tube?

[@Johnsarcade]

It's possible. You need to figure out if the issue is the tube or the monitor chassis. You could have a bad color drive transistor or pot that is causing the red to go away. More likely that then the tube.

[@fjdiazt]

I've been told this Rejuv process is only temporary and tube problems will come back after a month or two depending on usage. Do you think that's true?

[@rcawesome4123]

The extra holes were for a bar what would go across when the lock broke and or for extra security when they get sold they often dont have the key to the lock on it so just gets pulled off leaveing holes

[@Johnsarcade]

+Rc Awesome yes. I know. I patch those holes way too much on these restores.

[@kulgan96]

You can debug a crt and replace the tube i am learning so much

[@Johnsarcade]

I am not sure how many parts this is going to be. It might be six or seven! I'm not in a hurry! :D

[@GuruBrew]

Use automotive touch up paint with the brush in the bottle

[@viper155]

Hey john, what size and where did you get those leg levelers?

[@Johnsarcade]

Boy, those are just standard leg levelers. I usually get them from twisted quarter dot com

[@jerryspann8713]

Replace those speakers with shielded speakers. The magnet from those speakers are not shielded and is causing the discoloration.

[@MagikGimp]

Also, and don't hold me to my word on this (I know nothing!) but when you plugged the game back in the colours looked better to me (America on the globe looked green) although on checking screenshots it obviously wasn't correct. However, after your twiddling I had to say that it looked too red to me then. Now I am colour-blind with green a bit unfortunately but I also noticed that when you were rejuvenating the green gun the meter dropped a lot faster than the other 2. Don't know what that means

[@jayn8392]

I wonder how many of th monitors on these games John buys have bad/med screen burn. it seems like every decent deal I find in town the monitors are super burnt in.

[@Johnsarcade]

I have been pretty lucky. I've only had 1 or 2 games with unbearable burn. Gyruss one the worst.

[@jayn8392]

+John's Arcade Game Reviews & Tech thats pretty damn good for all the games you have done. It's a crying shame no one is manufacturing CRT monitors anymore. Nothing beats that warm phosphor glow

[@MrMariotwo]

Yes it will work in 1950's all from 1960 and on have it in the CRTs

[@Ryanr75rc]

Please Review Tapper anyway great video

[@bryanp9504]

You've gotta get a Go Pro, John!

[@SilentMott]

"If we can't get it in there, we have an issue with the gun"... Giggity.

[@Johnsarcade]

Ah, thanks!

[@ajcrm125]

Holy EM field. Make sure you wear lead underwear when you fire that tool up ;)

[@AndrewAHayes]

Do you mean the machine that goes "PING" ?

[@angeltoad4657]

The middle is not in the cuttoff

[@james42519]

knew that looked like you made too much.

[@Nighthawke70]

Buy a #10 can of beans. Eat the beans. (And the Lords of Kobol help anyone around you) Carve up the can and put around the drivers on each speaker. Issue solved!

[@n00blord111]

i want to steal so many things from you

[@Thevinylking69]

Please learn how to use a degaussing coil properly

[@Johnsarcade]

Thevinylking69 How am I using it wrong? I'd love to know if there is a method I am overlooking! #alwayslearning

[@inachu]

+John's Arcade Game Reviews & Tech The fact is you use it just the way he said.... you massage the tube. I grew up using magnets and it felt like painting the screen and moving the colors around like sand. You are using it properly when you "FIX" the issue. There is no indian rain dance that THEVINYLKING69 makes it seem because he is critical but gave no answer himself.

[@stevelarkins7002]

+John's Arcade Game Reviews & Tech When using the degaus coil you need to move the coil away from the crt until the rainbow effect dissapears. If you release the switch within range of the crt you are just magentising the shadow mask. Also rejuvinating tubes makes them weaker so it is a last resort option. Nice videos

[@Wa-De]

John, you did not use the degaussing coil correctly, and you did not wait adequate time for the heaters in the CRT to come to full effect before testing and rejuvenating. Although I thoroughly enjoyed your video, as an old guy who knows how to deal with these old technologies, I found myself virtually shouting out loud at you while watching.

[@sepertude]

You made several mistakes. First you never restore videogame monitors because they work all the time and 95% of cases you cant restore them. TV that sits for a while get restored often. Second you just had problem with RED cut off, should try to restore only RED, since your RED cutoff regulator on the right side was on max while others are not. Sencore compare all 3, if one has to be turned way on a lot and others not it gives you bad light on. Also whenever you have bad cut-off rarly you can restore it. The only thing you can restore it bad emision, others are just more for testing purposes. And lastly when you restore tube you have to wait 1 minute until it heats-up and get temperature up, than press restore button, not right away as you did. And last, if you do this often try to get Muter BMR2005, its way better and more sucessful than Sencore.

[@Johnsarcade]

+sepertude Thanks for the tips. I think when I did this, it was one of the first times ever using the Sencore. I've used it successfully many times since.

[@ordyne]

Roughest treatment to remove an anode cap ever.. That is precisely hat you shouldn't do :(

[@Johnsarcade]

+Craig Walker ooook

[@DoItAfterSmoking]

John! Love the vids man. your an inspiration to all collectors! I have a small suggestion. Maybe wear a GoPro headmount so when you need both hands you can set down the camcorder and cut in the footage... Might make your life a bit easier bro..

[@Johnsarcade]

I had a GoPro, it just doesn't work for my needs. When I need two hands I typically use a tripod. Thanks for watching and the suggestion!
