Hey guys, having an issue with my Ripley's.
The main issue is that the game is resetting randomly. Sometimes 20 seconds in, sometimes 5 minutes into a game.
Side issues: it's randomly scoring points. At first it would score infinite points usually on ball 3 when it pops into the plunger lane and sits on that switch (until it moves off), but doesn't do it on your first or second ball. After reseating a bunch of cables in the backbox now the first ball won't even pop up into the lane when you start a game and the monkey magnet thing starts scoring infinite points as if the ball is moving over that magnet.
Tested all the transitors on the whitestar board and none are shorted. Looked for something burnt up under the playfield, but all looks good (whole machine looks real good). Tried reseating all the cables on the CPU and Whitestar boards (made issue worse).
One more note: the last guy to own the machine cut off the ground pin on the 3 prong outlet plug (this couldn't just be a grounding issue, could it?)
Thanks ahead of time!

Thanks a lot Chris!
Yes, it's as if the power switch gets turned off and back on real quick. Complete power off with DMD.
The phantom scoring (I should call it that) is just like the ball is going over that switch and scoring those points over and over quickly (and with the related sounds). Points do not go back down and no other anomalies.
Thanks.

One more note, while it's doing the phantom scoring on the monkey magnet (latest thing it's doing), if I hold down the flipper button, the flipper will trigger and then go limp and keep trying to get back up (while making electronic buzz noise)... Must be a power issue, right? Working on the plug now.

Went into service mode and it said to check tech report. Tech report says potential damaged switches. In switch test, it shows all the trough switches and the idol eye opto open (the ones also listed as potentially broken). Ball still won’t pop into shooter lane when starting a game.
And one more thing, I tested pressing on the switch in the shooter lane during switch test (because that switch was causing infinite points sometimes), and when pressing that switch in switch test mode, it activates 3 switches oddly (shooter lane, one of the tombstones, and left spinner), which kind of explains the points racking up while the ball was sitting on that switch sometimes.
Thanks.

Thanks for the help! It was tombstone #5, right and left spinner open when I press the shooter lane switch.
What do you mean by tracing the line and why do the colors matter? (Sorry I’m pretty new on this stuff).
Everything looks good around the shooter lane switch.
Thanks.

Copy that, makes sense. Will have a look down that line now. And to confirm, I’m just looking for anything out of the ordinary like squished/damaged wire, a metal on metal potential short, burn marks, anything else?
Thanks.

Copy, thanks.

Alright, new plug came and replaced that. No change.
Looked under the playfield really hard at those green-orange and green-red seemingly affected lines of switches and I really don’t see anything that looks off…
The only thing on the entire under-playfield that I found that looked off was this connecter that looks slightly damaged and only has one wire going into it (don’t these usually have 2 wires)? This matrix correlates to the idol eye thing that was doing crazy point scoring so I guess it’s possible this could be the culprit. I don’t see any loose wire nearby that could have been pulled from this connector though… here’s some pictures of the little board and wires.
Thanks.

Also found this old thread with a similar issue and people suggested cleaning the optos or replacing them if cleaning doesn’t work. But the other issue of the shooter lane switch scoring points remains, and someone else on that thread recommended checking the tombstone and sling leaf switches because his weren’t gapped right and caused scoring from that shooter lane switch like mine, but I don’t know what he means by them not being gapped right.
Thanks again for the help.

Thanks so much, I will replace that connector. Would you mind linking the right connector for me? And do you know if there’s supposed to be another wire on that connector?
And maybe you didn’t see the last post, but there are 6 switches active in the test mode. I’ll double check again for other issues like a broken diode, thanks.
