If I say it’s you, there’s a good chance my Johnny will take a dump.

So, it’s the game.

I'd also say it's you since my machine works like a charm as long as I don't move it.

Moved it from my room to the living room today because I may want to sell it soonish.
Had to readjust 2 switches, 2 cables and 1 flasher after that. XD

Btw. here's a little video.

Well... as soon as I did that video I thought I should move JM back to it's place.
I want a BKSoR, but not THAT hard. - Or do I?

One thing I modded (out of the ordinary) is that the white paint on the glove now glows, since it's painted with UV active and Fluorescent paint (and shined on by a couple of conveniently hidden UV LED strips). I really wanted to have this since in the movie they originally glow (flicker pink-ish) as well.

That's just like, your opinion, man.

And I'm right ; ). (All in good fun. No need for butthurt cream).

How did you get the dmd to be blue?

It's much dimmer than white and reflects less on the glass below. Pics never quite show the color right...but yea - has a slight purple hue. You'd hate it.

It's just a LED Color DMD - that screen happens to be solid blue at that moment:

I have been trying to find a new translate with no luck. There is an English dealer who now has them in stock. They do not deliver to the USA

https://www.pinball.center/en

anyone in England or Europe willing to buy one for me? I would happily pay you for your time and trouble.

Be warned about pinballcenter, the quality of their repro products hasnt got a good reputation.

I have also ordered repro products from pinballcenter with mixed results some were good and others weren't great...

if you decide to order from them you can use a mail relay service called https://mailboxde.com - they'll give you a local address in Germany and then for an additional shipping charge, they relay it to the US. Used it twice, worked great.

Does anybody else notice the lit lane change is slow when moving it with either flipper? Increasing the multiplier for me is kinda hard because the lane change seems slow or seems to stick. Normal operation or do I have a problem?

I've never had a problem with either of the two JMs I've owned.

Normal. Every JM I've had (4 now) have done this.

Yeah,mine does it too, and this is what I've heard.

It’s normal. Pretty sure it moves with the flipper press but there is a slight delay on the insert light.

Well, I'm going to have to pay extra attention next time as I don't remember this happening but I could just be used to it.

I'm going to be making UV protector sets again.

I’ll be tearing one down this month. The hand does break at the end lol.

Did you do that video? I'm curious - how do you make the main view the background behind you as you are playing? I am away from the house until January, but I was curious as I'd like to do something like this too someday. Thanks!

Hi! Yes it’s easy with a green screen and some broadcaster software like xsplit.

I just joined the club and am super happy!

I'm starting to read the 68 pages of this thread, but it will take some time...

I was wondering... I find the playfield to be quite dark. What's the common approach to this ?
1/ Get used to it, that's the game's style
2/ Add some spotlights and led strips in some locations

I've added an LED strip in the back and trough and it's still pretty dark. Considering making some stadium lights.

It's not always "slow", just when you started a mode and there is more is going on.
(Wich usually is most of the time but not when you're just doing you skill shot.)
And it is not slow but might not work when you just shortly hit the button.
Seems to be a problem with the CPU (too slow) that it misses a pulse from the Switch lines when it's under load.

I have had this game for some time. I had it on location for about 10 years. The only problems where with the hand. I found a NOS hand on e-bay years ago but have not installed it yet. I need to go back over this post and see some of the mods you put on your games. Looks like LED's are a must. What are the other top mod idea's?

A lot of people don’t LED the GI because JM has so many fade and pulse effects it can look weird. That’s why I installed a GI OCD to fix that. The LED OCD and GI OCD are great but you almost have to see them in person to understand.

Thanks for the advice, Not sure what LED OCD is...I assume its a way of improving the way LED's fuction. A add on board I also assume. Who sells them? Thanks for the help.

LED OCD boards allow LEDs to slowly illuminate and slowly fade out like incandescent lights, instead of the almost instant on/off that you normally get with LEDs in pins that were originally manufactured with incandescent lights. As Waxx noted, you'd have to see it to believe how well it works and how good it looks. The LED OCD boards also help to eliminated flicker and ghosting issues if present.

You can learn more about it and buy it here: http://www.ledocd.com/

Comet Pinball also sells the LED OCD boards.

My game is missing the left hand side post at the entrance to the right ramp. Does anyone know the part number/Marco link to this post?

Figured I'd pass this on , since I already have a spare set and they are very hard to find.....

NOS set of Slingshot Plastics on eBay. I've bought a couple things from this seller......he's legit:

Anybody see these before? Though I don’t need one it’s the first I have seen with the art printed on the protector

I’m building a new Position Encoder PCB for my Johnny and am unsure of a component on the board. In the manual it only lists OPTO 1, but not OPTO 2. Looking at my board they are two different types. Does anyone know the part number for OPTO 2?

I just rebuilt one of my opto boards... on mine the 2 optocouplers were the same... (see pic below). Maybe your board was reworked using a different component?

I replaced one of the opto (which was intermittently failing) with this one from digikey:
http://d.digikey.com/LL20KX02XyJb0Sh1a0N070p
and now everything works fine!

Capture (resized).PNG

So I don’t own one, but I repair it for the local arcade. Any suggestions on how to rebuild the hand or any good guides for it? Can it be done in one shot? The game can’t really be down for long so if it’s extremely involved I probably can’t do it.
Also the hand works in test mode, I can move it just fine, but in game it blows a bunch of fuses.

Also this game suffers from the constant rebooting issue if you have too much going on, and the operator insists it’s not the power supply even though it obviously is. Is it cheaper to put the little board in it instead of rebuilding it or whatever needs to happen to fix it properly?

There is a fairly big capacitor on the cpu board (100µF I believe), try replacing that against the reboots. For the fuses there is a service bulletin from WMS to power the hand magnet from another fuse: https://www.ipdb.org/files/3683/Williams_1995_Johnny_Mnemonic_Service_Bulletin_87.pdf

Take it apart, clean everything, relube the screw rods with SuperLube, clean out the old grease of of the gearbox and relube with SuperLube, replace the X and Y nuts, reassemble in reverse order.
Take lots of pictures before you take it apart.
Should be able to knock it out in under 90 minutes.
When retesting the first time, make sure none of the wires get snagged.

Great stuff, thanks! Yes mine must have been rebuilt with a different looking opto (that does the same thing)

Here’s a good guide:
http://quinndunki.com/blondihacks/?p=1615

Considering the batteries I just replaced had a GOOD TILL date of 1997 I assume he probably bought it, opened it and plopped it down and never ever did this. I will check to see if this fix has been implemented.

Thanks so much for the help!

Thank you, I will do this aswell!

I'm trying to figure out the calibration of my glove in the auto run test. Everything seems fine except that the magnet doesn't drop the ball on any of the left-most sections. It will take the ball to that section, but never drop it. If I shake the ball loose so the magnet will release that ball over the playfield, it will continue the test onto the next ball and place that ball in its proper place (the center section) and the ball after that goes without an issue to the proper right-most section. Why isn't it dropping the ball into the left-most section?

Possibly related, in-game it will drop balls into the grid fairly reliably, but will often not release the ball during the CURE NAS or Loop it through Jones modes--those that begin with the ball being dropped into the 3 top lanes.

I've done factory resets, and cleared previous auto run test data. I'm also familiar with the blondihacks link that everyone posts on here. I've given up on the ball in hand switch, so I removed that. X and Y nuts are new, magnet is new.

You can remove the switch and the game plays fine, but it has a credit dot telling you to check that switch. I still have a new one if I ever feel like revisiting the mechanism, but it's playing more reliably without it.

I played a JM in the wild a while back and really liked it!
Now I got the chance to buy one. Problem is that it is too far away for me to actually look at and test the machine myself, so all I have to go on is pictures and the sellers word.. Scary.

Since I'v never owned a JM im not really sure what to look out for.

If anyone here could take a look at some pictures and tell me if you see anything strange, would be very appreciated.
Seller says everything is working and that the game is in very good condition, beside a faded cab (only pf and board pics in the link)

Link: https://flic.kr/s/aHsmHZ2jde

I have the switch installed but the credit for error. Game plays fine. What does the switch do? Worth fixing?

The switch does tell the magnet when the ball is inside the glove so that it powers up.
No clue why it does even work without it (you just closed the contacts so that the game thinks the ball is allways inside?) but that'd be the first thing to fix before to look anywhere else.

Tough to tell from the pictures, but I don't see anything obvious. It looks like a typical routed JM that didn't see a ton of play. The plastic at the top of the left ramp isn't original, and there is some cracking at the ramp attachment points which isn't a big deal. I'd mainly be concerned if the boards and hand are in good shape. Would definitely ask for a video showing the glove picking up a ball and moving all the way in all 4 directions, and some close-ups around the battery holder. Don't know where you're located but it would certainly be better to wait for a local one on this title. Even if the hand works now, it will likely need to be rebuilt unless already done by a previous owner.

Here's a good explanation from Blondie.

Looks good to me.
