So far you are doing great!
What is the single LED in the center of the EAF doing? I bet it is lit solid.
What are the rest of the LEDs on the FMDC doing? That would tell you at what point the FMDC failed in its boot process.
Remember that this machine has 2 logic power supplies. One in the wireway on the side of the machine to the mother board and front panel, and one on the opposite side of the door that the FMDC hangs on. I suggest you check this power supply with a good meter.
I would check all the connections to the FMDC board.
Give us an update.
