Picked up a Stern Stingray from a non pin guy. Sound isn't working, neither is the ball ejector. So when I set the ball in the shooter lane and start playing, several solenoids will fire - hit the drip targets, the bumpers fire too. Hit a slingshot, something else fires too. Should I start by looking for missing/broken diodes, like most multi-smumti-switch closure problems?
And not really sure where to start w the missing sounds. It has chimes but the game is actually electronic -
