Mate ... don't give up ! Half the fun is tracking down the fault .

Have you checked the
"'Game Over' relay. .. set of normally closed  contacts housing a RED w/ WHITE tracer. Ensure that they are clean and making connection."

Where are you located ? Maybe another member would be kind enough to drop by and give you a hand ?

EM's are a lot easier to fix than electronic pins I reckon .
The whole principle revolves around switching an earth to complete a circuit to a coil .
Most likely all that is wrong with your game is an earth is not getting switched through properly .
Either that or there is a break somewhere on the power side to the coil/s.
