I was recently gifted a fully-functional Bally Playboy in remarkably good shape. Complete newbie here, but I've been obsessed ever since and I'm now constantly poring over pin repair sites and YouTube vids. Many questions, but just today I replaced the Player #4 plasma display with a new Pinscore LED six-digit panel. Four plasma displays remain untouched. Easy to do, but now noticing some unusual display as a result. When the game is on and the display cycles normally between high score, blank, previous player's score, and four-player "00"s, the new LED display is inconsistent with the rest. The zeroes are the same, but when high score displays, the first three are correct, but the LED is 22,000 off. In the couple seconds the displays are normally dark, the new LED panel displays 888,888....and repeat. When I ran the display test from inside the coin door, the original four ascend normally from 000,000-999,999. The brand new LED panel displays all ZEROES when the rest display the 2's, all ONES when the others display 3's, fours and fives display normally on ALL five panels, FOURS display when all others display the 6's, FIVES display when the others show 7's, and the eights and nines display normally on ALL five panels. This grasshoppah has MUCH to learn, but any advice from the masters here??

Thanks for your tip. I unplugged the display and inspected all the wiring as best I could, and saw nothing seemingly out of the ordinary. Moved the wire harness around a bit, and the issue still persisted. I did have one extra new LED display that I swapped out for the new display I installed initially, and the problem was exactly the same, leading me to believe that the issue is in the wiring somewhere.

I checked the connector. I assume a "Molex" connector has a translucense since you suggest backlighting it, which I did with my phone's flashlight. What I noticed though is that (like your visual) every position in which a wire isn't present was clear, and that every position that wasn't clear had a wire leading into it. One of the positions wasn't dark like all the other positions, but wasn't CLEAR either. In other words, your illustration above shows a gap in the terminal. This one didn't - let's say it was sort of "grey", however, the position DID have the blue and white wire leading into it! I can attempt a photo if that will help. Not sure how to proceed to correct the issue, but thank you VERY much for the insight you have provided thus far!! MUCH appreciated!

Not entirely sure. Can that connector be opened and somehow adjusted?? Like I mentioned, I've never had a pin before, but I've been immersing myself in YouTube tutorials, and I am definitely LEARNING!! Just today, I successfully fixed a star rollover that was not scoring as it should, after watching a couple videos of leaf switch adjustments, and using the leaf switch tools I just bought online! As silly as it sounds, I consider that an ENORMOUS personal achievement! LOL

Thanks GP. I will now go into the other room, swallow a Xanax, chase it with a shot of bourbon, and see if Rosetta Stone makes a language program that I can cram to learn whatever language you’re speaking up there! Seriously though, I will study your post and see what I can come up with. I’m also a new retiree, so I find myself with some time to learn. I’m looking forward to the challenge. Again, thanks for the patience, as well as the advice. Cheers.

Thank you! This forum has been extreeeeemely helpful so far! That link looks like a great resource too. Again, thanks!

UPDATE: After many tutorials, forum advice and some practice with the parts, I FINALLY repinned the connector to the new display, and I’ll be darned....it WORKS, and it works like it’s supposed to!!! I guess I didn’t realize there were two wires per crimp, but I took my time with it, and I got faster towards the end. Not very electrically inclined, so I was actually amazed. LOL

THANKS for all the help!!
