I'm trying to finish up a Meteor project and having boot issues. All connectors are plugged in except for the sound board. New rectifier board. When I start it up, I get all of the MPU flashes per pinwiki. Test point voltages are good on the rectifier board, solenoid driver, and MPU. Solder joints on the MPU connector pins all look great. All fuses are ok. I have backbox lights and coin door lights, but that's it. No playfield lights, no displays, and I'm stuck here. I did verify the displays are getting correct voltage.
This is my first early Stern. Where should I start looking next? I'll guess connectors, but I'm missing so many things that it feels like it can't be *all* bad connectors, something else must be going on.
