This is where you really need the schematics to see the relationship between the AX and Score motor. Yes - it will be a simple fix, but only with a schematic..
From memory AX is in the head.. Lets try something easy.. Unplug the game, disconnect the mains.. Disconnect the plugs from the head and clean them with a wire brush - just the "males" ends. Look for loose wires. Reconnect..
