Check fuse F115. Also check the connector at J101 on the power board. Pull it off and examine it, does the connector (or the pins) look burned or discolored?

Could be something with J101. I wiggled it and something happened. It scared me
Your driver board is showing it has power but mpu board does not. Something between the two has a problem. Check the power connectors linking the two and the fuses. For giggles id pull the two boards and look on the backs of them for burn marks. Ifweelinate possibilities we’ll narrow things down.

No need to be scared. J101 is 5V from your power board to your MPU. If your MPU doesn’t get power it won’t boot, surprise!
If the pins are loose or the connector is burned or damaged it causes that kind of behavior. Sounds like you need to rebuild that connector.
For what its worth, your Power Driver board pictures shows LED4 out ( right in the middle of your picture), this is your +5V coming off the regulator on the Power Driver board. Nothing is going to work without that voltage.

Not exactly...but it can effect it.
Yeah, I wouldn't mess with J101 with the power on; J101 is your AC transformer voltage coming into the Power Driver...You should be scared messing with that one.

Ah, thanks for the clarification. Thanks Pin Guy!
Plus, YES, always be careful around live boards. Don't be too scared to do anything, just PLEASE be smart about it.
