UB300 was getting 5V 0A, replaced it and got 20V back. Board tries to start but I have no VCORE. DFU completed now, but still no VCORE. I have 0V on L7210/20/7410/20/30
All other voltages come on (big coils)?
Compare diode mode readings with good board.

All voltages present except those I told and L7702 and LB700 which are getting 0V. Don't have a good board of same model to compare diode readings.
Possibly bad CPU, or PCH.
Unless you find knocked off component, or broken trace on their areas.

Some workshops, intentionally remove/damage something when they can't fix a machine.
You should be aware of that...

Yes, I'm aware of that. Unfortunately for the costumer, only a replacement board will solve this now.
