Finally brought a JD home after months of searching!!! It seems to habe the L5 software and im getting the switch 28 error so ive ordered the L7 in hooes that it will fix the problem...it just started randomly so not sure why.

I posted this in the market but I'll also ask here....if anyone has an extra crane plastic (I know it's very rare) please PM me and I'll gladly buy it. IT looks like I just missed one from the post on previous page.

Also, I am signed up for the mailing list on the Color DMD site but do we know when the JD kits will be back in stock?

Thanks all!

Hey everyone...I have a question regarding the subway trough lamp board.

First, I can't find anything on these in the original manual which leads me to assume the bulbs in this location are "GI". WHAT is the standard configuration for these? We're they all standard 555 bulbs or do any use flashers?

Second, for LED purposes I am trying to figure out color as well. IS a white color the standard for this area or has anyone experimented using yellow or red? A mix? Just looking for some pointers as this doesn't seem to be a well documented part of the machine....yet it takes a ton of lamps.

I'm hoping someone can help me with a strange problem that I have just developed within the last 3 days on my JD.

I was playing it and everything was going fine. Out of nowhere, without any funny noises or crazy sparking electronics, the lower left flipper just stopped working. Nothing. The other 3 played just fine.

I get no error codes when I start the machine up as is. When I go to flipper test in the diagnostics, all 3 work perfectly for hold and power but the lower left does nothing.

When I shut it off, replace the 3A fuse for that flipper, and turn the game on it instantly throws the lower left flipper up but has a rather nasty humming/buzzing noise. I immediately shut down and if I replace the new fuse with the original (presumed blown fuse) it will start up as before and will test fine except for that one.

In this state, the flipper buttons on the cabinet activate the other 3 just fine. Can someone start pointing me in a direction other than the circles I've been running in? I can not figure this one out. Seems to me that something strange is afoot.

In the picture below the fuse in question is the bottom left one F904. Please help, and thanks in advance!

Thank you! Ok, so I did just pull the board but it appears to be pristine on both sides, no burnt traces or points that I can see. Checked all of the cables in the head for possible shorts too but nothing looks out of place. It's just so strange that it just stopped mid game with no warning.

I have a multimeter but I'm not an expert with it by any means. I just know that something caused the fuse to blow and something is pegging the voltage when I put a new one in. Is it possible the coil itself or the diodes could just "go" ? It has all new hardware including sleeves so....once again I just don't know.

Thanks!

Ok I'll give that a try next. Thanks!

Thank you!!!! What is the best way to check that with a multimeter? Do I need to have it hooked up and wired into the machine or can I do something as easy as testing the resistance with it out of the backbox? I apologize for the questions but I haven't had to worry too much about electrical/board issues up until now.

aaaand...something else that just dawned on me. I have a Demolition Man that I could just grab the Fliptronics board out of and test in the JD....if it works, voila! I wish I would have thought of that yesterday

Thank you all so much! I'll test her out tonight after work. You guys rock!

I can't believe it.......I'm a little irked that a new board component would go so quickly.....or that there is clearly a common issue....but I'm more amazed that mine is presenting the exact same issue on the exact same transistor!!!! Check these out, a good transistor picture of Q11 (they all behaved this way) and then Q3 which is flowing both directions and clearly shot. I can't tell you how much I appreciate the guidance....

Now I need to figure out how to replace it I haven't done any on-board solder work before, just coils and sockets. Should be a hoot.

Thanks again guys. More to follow, but at the very least I need to order a new transistor.

I can help with the Pinball Center plastics question. I ordered these about two months ago. If you need to get a badly cracked or worn one replaced for service they will do the job, but they are a bit like a "20-20 car"....at 20 feet away at 20mph it looks good, but upon closer inspection....

The colors seem somewhat bland and there is a lot of washout like you would expect from an ink jet printer. The subway plastic isn't as big if a deal because it's largely hidden by the deadworld, but just beware these are not CPR quality plastics. See my pics....new ones have no part numbers written on art. I had the same issue with Demolition Man plastics i purchased from them....just had higher hopes for JD.

I hope this helps you guys!

PM sent

You've got it. I'll definitely let you know if it gets to that point, I'll have a better idea once I get more details from Ron.

Thanks!
