Mentioned this in another post, but after working on rebuilding a board/new connector pins/etc. I put everything back together, push the button to start a game, then nothing happens. I'm ready to tear back into everything again, check voltages, check fuses, etc. (and maybe have once or twice) before I realize the credits zeroed out and need added back in before a game will start. My old Sterns don't have a free play option. . .
