Just purchased a Playmatic Space Gambler for $100. The major issues I need help with are the LEDS scoring and sound (also right flipper but think it just needs adjusting). The game will start and shows ball one, ball gets kicked and you can play, bumpers, targets work and when the ball drains it goes to ball 2 and kicks to shooter so it seems that's all working. What is not working is the scoring or sound. Scoring first, on the backglass there are 4 sections of leds that are suppose to light up, on my back glass only the last 2 digits of players 2-4 light up, as you can see in the pictures I attached they are different section of LEDS that don't work. This is my first SS pinball so not really sure where to start (all fuses look good) I know from my searching that it's hard to get help on playmatics but hoping someone can help.

THANKS!!
pic will all lights on is from IPMD for ref on how it's suppose to look.

Ok so I worked on it a little bit tonight and I think I have narrowed both issues down to the decoder board. What I found is if I unplug the 4 wire sets that run from decoder to leds then the sound starts working, it sounds bad but it does work. I have attached pics of the decoder board and what I unplugged. Any ideas what to do next?

So no progress....actually now the machine is finicky about starting a new game. Seems like the credit likes to reset back to 15 sometimes and wont start a new game, other times it will stay at say 11 but will still not start new game....after pressing button and flipper buttons a bunch of times it finally starts a new game. I found the manual here http://mirror2.ipdb.org/files/2250/Playmatic_Space_Gambler.pdf but did not help much...any help would be greatly appreciated

Kinda lonely in here..... Not sure if anyone is listening but writing this out seems to be helping me at least...

I have found that the 2 leds player 2-4 that I thought were working are really just lamps behind them so no leds work.

GOOD NEWS: I have also found that if I disconnect all connectors that go from decoder to LEDS then the game plays perfect besides the LEDS, sound works,credits works, new game, etc, its also keeping score because I manually kept track and got a free ball at the correct score.

BAD NEWS: Not sure what above means and the next step, I am hoping someone can chime in and point me in right direction.

At this point I will take any reply...even a "sorry can't help but good luck" just give me something!!! LOL!! all jokes aside I am hoping someone will reply with some SS LED/Decoder knowledge

THANKS!!

nothing? are all the experts on vacation?

Thanks Nick! I am hoping to get nick and familiar with the decoder board this week, I will report back what I find. Thanks again for replying!!

So I am finally getting back into troubleshooting this pin. If anyone has any ideas or tips let me know, otherwise, I will continue to use this post to track my progress.
