Re: DMD for Data East pin?

ralphwiggum ralphwiggum ralphwiggum ! (this works like Beetlejuice, right?) =) So after the power supply replacement, I noticed that the "Ball N" and "Free Play" section of the DMD was garbled, intermittently. I finally got around to re-seating all the cables (no change) and taki...

Re: DMD for Data East pin?

Congrats, feels good to get it going again, doesn't it? :D I suspect your dmd logic issue was caused by the low 5 volts. Anything under 5 gets finicky on these boardsets. If you want your other supply rebuilt and can leave it with me for a few months(yes months)..... I can get that one back up and ...

Re: DMD for Data East pin?

It lives! I don't quite have an explanation for why I blew a fuse last night. When I connected it all up tonight (spare DMD in hand), it just worked. The DMD CPU boot issue is gone, too. I suspect it was power all along for that issue as well. It was 5.12V as I recall with the new X-Pin board, and t...

Re: DMD for Data East pin?

A friend has a Bally/Williams DMD, I might use for testing this thing. Are those compatible? I *think* so?

Re: DMD for Data East pin?

You can use the ground straps in the backbox for ground. Did you mention before that you tried hooking up high voltage while the machine was on? If so, you could have toasted that dmd too. Is it a Cherry display, or a Babcock? If it is a Cherry display, those are a little more finicky that Babcocks...

Re: DMD for Data East pin?

With high hopes, I installed the new X-Pin power supply tonight. Looks like it immediately blew the high voltage fuse, F3. Which of course I don't have on hand (same type as was blowing on the old power supply, interesting). I see after removing it that there's been a bit of a hack job on this old p...

Re: DMD for Data East pin?

Aye, yeah, I think I fried it. Will do that; order a replacement then set about trying to fixing the original.

Re: DMD for Data East pin?

sorry, reading schematics from my phone.... i will grab the manual tonight and confirm what i am trying to see.... Aye, thanks. So, whatever I did to it, seems to be re-blowing that F7 fuse, bah (even with the DMD disconnected completely). Seeming like I fried something good on that power board. Th...

Re: DMD for Data East pin?

are you testing the fuses with a meter, or are you visually inspecting them? take a look at fuse f3 on the power supply board, this is the fuse for your high voltage. With a meter/continuity tester, yeah. OK, where in the heck is F3? Pic attached. I see F1, F2, F4, F5, F6, F7, but no F3! Haha did I...

Re: DMD for Data East pin?

Well, crap. So the immediate problem was the blown fuse. I replaced it, and checked all the fuses on the power board, all good. But I'm now not getting any high voltage to the DMD (-110, -98, or 68). This is a separate problem *I* caused when I pulled this connector off last night with the pin power...

Re: DMD for Data East pin?

It isn't the resistance from a poor fuse holder, they literally have zero strength, and while they "appear" to be making solid contact on the fuse, they really aren't. In this case, when they are weak, they momentarily lose connection enough to cause all sorts of weird issues. Right, but ...

Re: DMD for Data East pin?

Awesome, Ralph. I really appreciate it. I'm still getting into the tech (necessity being the mother of all invention, eh?) now as this is my first pin, so I'm sure my terminology is dodgy. Headed over to Menards shortly to see if I can find the fuse I blew in my idiotic monkeying around last night. ...

DMD for Data East pin?

I'm currently troubleshooting a problem with my Lethal Weapon 3 where the DMD is not fully booting. Tech details here: https://pinside.com/pinball/forum/topic/data-east-lw3-dmd-possible-power-issue-1 I'm thinking more and more that the DMD is bad (initially had suspected the power supply, but now me...
