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

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

KenLayton helped me through it, so credit him with this info!
Here is the ballast that I bought (slightly cheaper):
