You are lucky, I have a blank playfield and a metal ramp until tomorrow...

Bend the end if the flatrail very slightly until balls roll thru the narrow escape cleanly from the idol exit. Roll them by hand.

The wire gate should be one way and have no binding but be free and loose.

This is what I did to fix mine. Works great now.

That's an impressive looking playfield.

One question. The finish on it looks matt/satin. What's been done to the playfield itself?

This a digital print, the matt appearance is the paint itself. Next step is clearcoat.

Hey guys, I noticed a few days back that the led ENT & lock/center shot lights on my IJ are all out (see pic). All other playfield lights including the led that lights the center shot area are all working fine.

Any ideas why this group of lights would all be out? Is there a fuse that controls those lights that may be blown?

Wire fell off?

Thanks. I will check that when I get back home. Anyone know of anything else that could cause that? Will pro ably try to troubleshoot this weekend.

Where do these drop target mods come from?

Pinside member Indypinhead. Just pm him. Great guy and product. Does the WOZ winky too.

I have reached out a few times, he has been super busy. I may try to print some as I have a 3D printer as of recently, I’ll let you know how it goes, but I don’t want to impede on his turf I would not sell them but if I can make a model that works I’d just share the file. Some are already available on thingverse

I reached out to Indy and he was dealing with a lot of personal stuff, so he might not respond for a bit. I want his drop targets as well but told him my machine isn’t going anywhere so get back to me when he’s ready

I might be able to beat this one, i'm starting a tear down next week on a new to me IJ (just joined the club). This sucker is FILTHY, i'll take some pics...

Dirt off challenge accepted

Looks like dude lowered his price and posted some better pix.

My idol would error out and it would just start ejecting balls everywhere... figured I might as well get it all cleaned up first and then troubleshoot issues...

Getting there on disassembly...

That will clean up fine. I used some Novus 2 to get off the tough stuff. Make sure to put some cliffys on

I would start with simple green and some elbow grease you would be surprised what that will accomplish and non abrasive

Yes, he finally did put up the pics of the play-field crack / damage. He said he would drop the price 100.00 per week until it's sold...

Better off with VM&P naptha on a rag instead of simple green.

Cleans better and wont raise the grain of the playfield or damage anything..

Water based cleaners are bad if you have to use a lot of it.

Pics are still poor. I still can’t see the cracks either

I had to zoom in really close (under left and right flipper) so most who are looking to buy, will most likely not see them as you have stated..

Gotta zoom in, look below the left flipper. Looks like a screw came up from beneath the pf. CBFD107E-A362-493E-9153-1524B0AA7C5E (resized).png

Honestly I have seen worse sell for more.

Yeah I’ve got naptha, so I’ll use that once I get the initial dirt off... should clean up nice, is decent shape overall.

Yes, there it be...

Guns, what are using when cleaning a really dirty play field, Naptha is not available in ca. Will Amazon deliver Naptha to ca?

I’ve had good results with denatured alcohol.

Thanks

ROM upgrade questions for those that have burned their own. I currently have CPU L5 and Sound L2 and noticed the chips sets are different. CPU Rom is an ST Micro M27C4001-10FI and Sound Rom TMS 27C040-10 EAP9310325. When you burn the new chips, do you match the existing chips or just go with a single/same model for both CPU & sound?

NM, looks like it doesn’t matter. I got Malaysia chips (not what I ordered, I order TMS). But they worked

Curious if the subway ramp issue will be fixed now as it appears they included longer firing times in L7

Alright, got my IJ back together, but the issue i had before the tear-down is still there.

It'll work for a bit, then in the middle of a game, the display will go out and then it will just start launching balls in a never ending loop. If you power the game off and back on, then as it's sitting there, display will be out, it sounds an error (but you can't see it since the display is out) and it'll launch all 6 balls, and the coil in the subway release will just keep firing. If you start a game, then it just goes into launch ball mode.

I did check for 5v at the display. I have a ColorDMD installed.

Any help would be greatly appreciated!

Put the old display back in and see if the problem goes away.

Is this a known issue? I've never had a bad ColorDMD before, I will give it a go though.

My game did that shooting balls over and over thing when the trough opto came unplugged. I didn’t have any CDMD issues tho.

It’s probably less a bad CDMD issue and more a weak power driver board issue. I believe the CDMD and the optos both run off of the 12v section.

Yeah, i unplugged and replugged that one in, i wonder if it's bad...

Same issues with the regular DMD, only difference is that the regular one stays powered, whereas the ColorDMD goes blank. However all the rest of the behavior is identical.

Ok, I'll do some digging and figure out where to measure the 12v.

Hey Chris, sounds like you blew out fuse F116 on the power driver board

I would check that first. If its blown out, put back the original display first then replace the fuse.

Then go back and see what you may have done wrong with the ColorDMD

The test points are in the upper left corner of the power driver board and are labeled.

Thanks, great info!

After sitting over night without power, it booted right up this morning. So i'll have to play until it resets again, but it doesn't just do a full-reset like i've seen in some of the videos, once it glitches, it's stuck in that weird state until I pull the power to the boards or let it sit for awhile without power.

Alright looks like my 12v is going out, LED 7 isn't lit and i'm only showing 1v at test point TP1 while the game is freaking out. Which explains why the mini-PF, the Idol and all the optos are spazzing since they don't have the proper voltage.

Trying to find another fuse to check that, also looking at the PinWiki to check some other things.

Its not the colordmd and you found F116 12v. Try new fuse. Doesnt matter which display but the colordmd is also 12v.
If fuse is new and you still have issues check back.

Yup, just saw that J116 is the 12v for coin door (where the colorDMD taps into) so that makes sense why it won't boot the ColorDMD.

Yeah, trying to find another fuse in my stash, otherwise it's BR5 or C30 causing the issue on the 12v circuit.

Before you go there its all about fresh fuses.

For sure, just can't seem to find a 3a laying around, which seems stupid, LOL

Looks like i bought 5 3a slo-blo's back in March, just need to find them.... don't think i used them all...

Oh god,been there. Where the F*** did i put those fuses. If you saw my parts room....yes, i have a whole room of pinball parts.

New fuse, same issue, so BR or cap i would guess at this point.

No----Take your power box apart inside coin door/service box/ power switch box.
UNPLUG GAME FROM WALL FIRST!

Inside this box are the 2 things almost no one replaces or checks first. All power to boards comes from here. Poor ignored power box on so many restorations ive seen. Start fresh with a new Varistor and Thermistor. both available on most pin parts sites. Marco's etc..
Replace these 2 components, most all are original and worn and old and are failing. This can cause issues for the 12v/optos and displays.
