Old thread but perhaps this will help someone.
Problem Statement: Iron Maiden working fine, followed instructions to update code. After inserting USB memory stick and turning pin on, the pin does not boot, VA and VNB do not light up on the CPU board. Playfield dark, no display.
Remedy:
1) Machine is powered off, USB stick not inserted.
2) Remove SD card.
3) Power machine on - wait a moment (nothing / dark).
4) Re-insert SD card.
5) Power machine on with USB inserted.
6) Update happens as expected.
Summary: the SD card may have not been properly seated or else some other events happened as a result of the above sequence to resolve the failure to update.
