First start with this guide:

I'm sure more people will help soon as several own that specific machine and will most likely have good suggestions. Oh btw ... did you check/replace the big filter capacitor on the power supply ??? It might be drying out and going bad after all these years.

The capacitor will look something like this:

It usually mounted separate somewhere in the backglass cabinet. It's quite large. I guess I should have put a coin next to that in the picture. That particular capacitor is about 3.5 inches in diameter. It's not part of the power supply board but a main power supply component that often goes bad in an aging machine. The electrolyte solution inside dries up over time.

I don't know that particular machine so it might not use one being newer. Those connections on top are screws.

Try reseating all your eproms ... it's possible there are just some dirty connections in the chip sockets after all that time. Trying to help.
