Title: Jurassic Park
Post by: JRChristenson on May 03, 2012, 02:24:47 pm

I received this as a gift (maybe more of a curse?). I know a fair amount about building MAME cabinets but nothing at all about pinball machines. Right now this one lights up and that's about it. Can anyone point me to some kind of checklist or standard procedures for diagnosing one of these things?

Any help would be appreciated.

Jason

The manual looks like it will be helpful. Thanks. Unfortunately the documents pinballjim linked to seem to be missing or unavailable.  :(

PBJ was referring to Clay Harrelson's (SP?) old guide for pinball repairs of sega and data east machines.   Clay took it off his site (or behind paywall i guess) but it's out there if you search around.  If it's like his bally stuff, it's not a super comprehensive troubleshooting guide like you could find for a vehicle, but it's the closest thing out there.  Pinwiki.com is a very similar site. I'm not familiar with their data east coverage, looked decent at a glance.  None of these get super specific on individual machines so you still need the manual.

Come to think of it, I do have some really nice troubleshooting guides that I downloaded in pdf format.  I'll post them shortly.....have to get home first.

I've finally started taking a good look at this machine. It looks like the main board (CPU?) and the power supply board both need to be replaced. My question is this: How likely is it that I will spend $400 + replacing those things and still have a pinball machine that doesn't work?

Any thoughts?

I've done it.  gameplan sharpshooter with burned/corroded mpu.  New mpu and I hoped it would make it all better.  turns out, no.  I'm considering unlooming the entire playfield harness to try to track down shorts. 

replacement boards are no guarantee of anything unless you've done the work to narrow down the problems to the specific board. 

I would get the power working first (giving correct voltages at the board test points), then see what else is going on from there. The other boards need correct power before they can be tested accurately.

I haven't really done anything with this yet except a few minutes here and there. Can anyone tell me what price card this would have had in it?

Rottendog will refund your money if it's not the board.

So far I haven't had to use that = as replacing my Power Board worked for me.

I then sent my old one to coinop cauldron to fix as an extra.
