I own a Williams Space Mission pinball machine, which works fine, except for the fact the score you get for certain things doesn't correspond to what the playing field says you should get for them. The bonus that shows on the field also is not added correctly to the score. I am a complete noob to pinball repair, so if this is something super complicated than that's okay, but if it is just a matter of changing a few switches or something equally simple, some guidance would be much appreciated.
