If all that you are seeing is some displays light up and no attract mode lights then your MPU is not booting.

There are numerous possible reasons. The root cause takes expertise to find.

Once you’ve verified power (5VDC across the electrolytic cap on the left side of the MPU) then its a matter of detailed testing.

Reset
Clock circuit
RIOT test

I’ve been fixing these for years. LMK if you’d like me to take care of it. I have a Spider-Man here too.
