LOL. That jumper thing could only happen to you. This was a cursed restore. Congratulations. It looks beautiful.

Congrats John! I’ve had a few of those ‘is that really all it was?’ moments fixing pinball machines. I have a love/hate relationship with those moments. The eye opening moment when learning has occurred is a good one. Nice going.

Love watching your videos. This was quite a journey, so glad you kept working at it. Thanks so much for sharing it with us. Great job!!

Finally! Envious and loving it. Can not wait to see you get to new projects.

That was a gloriously brilliant ending... it being something so simple. I never would have thought of that jumper. Our long national nightmare is finally over. XD BRING ON THE BRONCO!

Just wanted to leave a comment and say thank you for documenting this. It has helped me troubleshoot my MK2 Cab and get it up and running!!

Holy god John I have experienced this level of frustration working on a Neotec 2701 !!! So frustrating !!!!! I was getting anxious again watching you go through this, PTAD Post Traumatic Arcade Disorder !!! HAHAHA Very happy for you man. This machine will definitely have a sentimental value for you every time you look at it with all of your blood sweat and tears you put into her :-) Congrats sir !!

This update is going to help me so much. I restored a MK II a long time ago and had everything in place and then the monitor snapped off and I could smell smoke. I am planning on doing everything you did to the PCB to try and resurrect it. This guide has been great and I am now ready to order parts and try to finally finish it up.

this came out gorgeous! thankful we got to hear from future john before the video ended

You earned this one man! What a beast of a restore.

Way to go John!! Looks awesome!!! I’m surprised you didn’t notice it earlier when you had the board off during the solder reflow. In the immortal words of Boris Karloff....ITS ALIVE!!!!!!

I was like noooo, so close. Then that jumper. Nothing is as satisfying like when you find the problem.

Nice! Congrats on finally getting it all going. Very interested to see what you work on next!

Awesome, we're back in the basement! I'm really looking forward to MKII finally working for you.

I'm glad to see you fix your mk machine.. Congrats🎉🎊👏👏

Wow! I can't believe that you restored the Mortal Kombat II arcade cabinet, John. Finally.

Learned about deoxit thru your ch, best stuff I've ever used for cleaning my connections!!! Thanks for all the good info on what u do!!!!!!

FLAWLESS VICTORY

Sweet John actually doing a arcade video. I love these.

Love your vids bro..I have a arcade machine in my mancave and when I seen your vids on here explaining how things work ect it gives me inspiration and ideas and troubleshooting tips on how 2 toy with mine👌👍

I just spent 2 hrs watching you struggle for 2 or more hours... For a damn jumper! Was it worth it... YES!

Awesome, glad you fixed it pal, looking forward to final bits to finish it off, stick it in its hole and a quick gameplay, then you can move on with your life 😎

Yes Pubble Bobble is a great game lol. Grats on finally finishing this game John sheesh it's been a long time.

Yay! You finished the MK2! Good job on finding that jumper! Well I got good news my Gauntlet machine (the one I got for 50 bucks) it has a Hantarex monitor too. So I'll just send that your way to let ya fix it because you seemed to have no problem fixing yours hahaha just kidding this thing is going in the trash. Keep up the good work John and congrats again on "Finishing" the MK2

great job John, another great restore!

Finally a bit of luck with this game! Glad you cracked it mate, looks fantastic

John love the video quality of your Sony Handycam! I know this isn't Mortal Kombat related...peeking over to the left at your Ice Cold Beer coin door. Mega thanks for reading my mail John!!

John, finally you got that bad boy fixed. It looks amazing. I hope you do a follow game play on MK2 👍

Awesome job on the restore! MK2 is sweet!!!!

hey john great video loved every bit of it hope u get it sorted m8

Awesome! Great work John.

MK II looking great man!

Crazy fix. Nice find dude.

this is so interesting. Now they are building super game computers, but this game is like archelogy. Keep it up!

great video john the game looks great!!!

Holy Moly! 2.5 hours long! I’ll have to watch it tonight... 👍👍

FIRST. Congrats on 40k, JJ!

Congrats, it is done!!! "It has begun"

It's always...ALWAYS...something simple and silly...that will stump you. Reminds me of trying to defeat noise in a cassette cable not realizing the replaced stereo cable causing trouble with a stray ring line grabbing noise. Glad to see things worked out in the end...

What an ironic twist and ending to your frustrating Mortal Kombat 2 John, looking forward to the video of you playing it. Hold down Low Kick a few seconds then let go for Liu Kang's bike kick

Congrats finding that John!

I was begging you to plug the Tetris board back in and you finally did! :D

Thank goodness you finally do it and really in shock that simple jumper cause to has bars on the screen and it was shocking. Anyway MK2 is finished. hurrah.

Yes!!! Finally John you did it .it looks awesome man now you should do a Ultimate Mortal Kombat 3😂😂😂😂

just a jumper? never seen a test pattern jumper or messed w one wth glad you figured it out!

Been waiting on this one for a while!

Give the board a good scrub with an used soft toothbrush and some isopropyl alcohol , for the love of god :D A very clean board leads to much much less problems in the long run :D

hi john! according to mame git, this is the explanation for the extra button: /*Note-the real MK2 board has a special cable designed for SF2 cab conversions that has the 2 SF2 Medium punch/kick buttons as block buttons for MK2. The secondary block button registers in test mode, but does not have an indicator light show up. During gameplay, the second block only functions temporarily. You can hold the button, but the character will only take a block position for 1 second. This is correct behavior.*/

7:22 the game gives him the finger. Lol that's what I thought it was when I first saw it

Thanks for the new video!

According to Ken Layton on KLOV: "Thick, dark, stationary vertical lines (1/2" or wider) are called "jail bars" and that symptom is ALWAYS caused by bad electrolytic capacitors on the monitor. Thin, light or dark vertical bars (1/4" or less in width) are generally caused by bad video ram or other bad component on the GAME board. Thin, white diagonal lines across the picture are called 'retrace' lines and are caused by the "screen" control on the flyback turned up too high. Thin, dark diagonal 'worm wiggle' or 'herringbone lines are caused by a bad ground on the power supply. Thick, rolling HORIZONTAL lines in the picture are likely from bad filter capacitors or shorted voltage regulator on the game power supply." Edit: CRAP! Watched the last few minutes and saw that you fixed it. Good catch!

Great to see you finally get MKII up and running. Really enjoyed watching this project evolve. Have you got something in mind for the next one once MKII is totally wrapped up?

Finally! This restore probably has more episodes than Days of our lives! The game looks fantastic though :)

Wow something as simple as that, top work John, and that monitor looks really crisp, personally I prefer Mortal Kombat 1, is that the same pinout? Possible to have both boards and a switcher?

I'm building a Multi-Kombat that I'm documenting on my channel. Nice work!

Epic win! 😎👏

Now go to the secret EJB menu! ;-) Congratz on finishing it !!

Damn, even your workbench looks cool

John please buy some contact cleaner and clean the pots, also that battery terminal was dirty as hell

Please someone make a clip of John saying "we can't screw this up" and then cut to him completely missing the crimp. Best moment of the video

Yes ! Well done

Great job - now im curious what will be the next project :-D

Job well done matey ;)

Very nice Channel John and a Lot of good informations:), but i think the Monitor is damaged...oxidised or Something?

First lol glad to see this getting finished.

Welp, I am not going to bed anytime soon lol.. I wonder if we will ever see a black tiger arcade cab on this channel.

Wish I had a basement arcade like his :)

nice to see that the past John called it..."hmm...maybe it's something really stupid" lol

Ya need to finish this.

So you are the one ringing that bell on the VGO podcast!!!

finally, lets play....!

That damn jumper!

If you adjust the shutter speed on your camera you can eliminate those rolling lines on your monitor.

Tomorrow, I need you to go order a Molex pin extractor tool. Don't risk your hands!

Whoaa, you finally fixed it! Ughh, don't you hate it when you did all or most of the hard stuff BEFORE you discovered the little easy thing that fixes it? UGHHH!

Mortal kombat LIVES!! FLAWLESS VICTORY!!

Now you have to became good in mk2! Toastyyyy

you should do these restore videos live so people can comment ideas to help solve the issues with the games.

Hey John, tried to join the Johns Arcade forums because I have some questions . But been waiting for account approval for over a week :) did I do something wrong during registration?

I swear I seen part 20 in my video suggestions.. I went to watch it... and then it was gone... So I decided to rewatch this episode instead xD

Congratulations John! that jumper problem was annoying...is there a reason why those lines wouldn't show up on your test pattern machine hooked up?

Will you do a final video on MKII showing how it looks with all the bulbs replaced and some gameplay :) - ps I want a MKII now :D

John, whats the best way to clean the coin doors? One of the coin slots is sticking!

I'm going to be hearing "Ya! Huh! Ungh! Ooh! Ah! AWWWW!" in my sleep now.

God bless Polos!!

Nice! You've also now caused an alternative reality in the John's Arcade Universe - can we look forward to some interesting videos from both Past-John and Future-John? What if in the alternative universe Past-John never discovers the jumper and he ends up being driven insane while in the other universe Future-John is sitting back smiling, feet up, chomping smoked brisket with Adam and Matt happily playing MKII in the background? All is not lost though as Past-John is somehow able to create a temporary comms link to the present universe (from a broken popcorn machine and spare parts in the garage) and is able to call up 520-FEEL-VGO and leave a desperate plea for help. Will Future-John understand the message and be able to help save Past-John?

Well, you've got more than one PCB there, so you should specify which one you're talking about. The monitor alone has at least 3.

THAT JUMPER LOL

Did Turning you hobby in to work at the hanger, make it less fun?

I like stupid John, future John knows too much :P

What have you done to the popcorn machine?

could try deoxit on the jamma connector

IT WORKS!!! woo

👍😎

Maybe you can do a restore video on that popcorn maker.

john is that remote board specifically for that monitor or is it universal?

Has this MK restore been more of a project than Journey escape?

I saw you at the hangar getting turkey drumsticks.

Haha, 47:06-47:08 and 1:36:40-1:36:42: hey, you're a poet! (Oh, of course! It's no accident that they put the downs with the _browns,_ is it? :-D ...)

*Your other driving game had a 25" k7000 with a Midway sticker on it. That most likely came out of an MK. Any reason you didn't use that monitor?*
