    I have a Stern machine with one 24 inch 18 watt fluorescent bulb behind the back glass. It went out and any new bulb just flickers once when you turn on the machine then nothing. If you had to guess, do you think the problem is in the light bracket connections on either side, a fuse, or the power supply on the board. Thanks so much.

    Do you have any other sterns to swap parts from?

    Could be the ballast. This one should work for Sam versions.

    It's hard to give specific help without more details.

    Did you also replace the starter?

    I did not replace starter yet. Should I replace both? Also, am I going to get electrocuted doing this? Thanks.

    So, this same thing is happening to me. Replaced the starter and bulb. Flickered and then nothing.

    Any resolution?

    The only other thing in the circuit is the ballast. Replace that and you should be good to go.

    The flicker is the ballast wiping out your bulb. New ballast, starter, and bulb.

    Switch it out to a direct wire led bulb

    Absolutely a blown ballast, which will blow both the bulb and the starter. It's an easy swap out with a new ballast like the one listed above, no polarity to worry about. Do that, use a new bulb and starter, and you should be good to go. If you disconnect the ballast and measure it you will find that it measures close to zero, which is shorted/blown. The new ballast will measure about 22 ohms.

    Same thing happened with me on my Sega/Stern The Lost World Jurassic Park and member KenLayton helped me through it, so credit him with this info!

    Here is the ballast that I bought (slightly cheaper):
