Hi. New user. Just bought a 1991 data east Star Trek (25 anniversary). When multi ball feature starts it won't top. When balls drain they just keep auto launching back into play. Only ways to stop are by tilting or turn off. Any help would be appreciated. Thanks. Peter.
I would check that the right number of balls are in the machine.
Also go to switch testing and make sure all the ball trough switches are working.
