So I just picked up a Mr & Mrs pacman pinball. It was in rough shape and needd a good cleaning. As I was reconnecting one of the connections on the power supply board one of the pins snapped off into the molex connector. The game turns on but the speech is muffled and it's playing weird. How do I 1. Fix the connection and 2. Get the stuck broken pin out of the connecter? In the picks the top pin is the one that broke.

Quoted from ArnieC:

I think what he is saying is there is not a wire in j3-1 so he does not need to do anythingso basically I can just leave it? That one pin doesn't make a difference?

Quoted from Inkochnito:

He should replace the capacitors on the S&T board.
Check the roms if they have tarnished legs and verify if they are still good.
The speech comes from those roms.
And yes, the pin is not used and does not need to be replaced.
However, you are now missing the pin which should center the key on pin 2.
Shifting one space up is possible and would have bad effects when you do.
Replacing the single pin in not nessesary, but very adviceable to prevent mistakes.

YES! I think that is the problem. I ordered new capacitors so hopefully that will fix it.

How do test the roms? With a Multi meter?

So I figured out the board was being held in place by two metal screws. When the screws touched the metal on the front door it was making the sounds not work correctly. Once I mounted the board without the screws the sound was perfect and the game played correctly. I did order a capacitor kit for the sound board so I'll change them out anyway. Thanks for all the help guys!
