Hey there, have you poked around in the 'power good' circuit, which from the narrative, latches on only when there is no fault condition, enabling the main board?

The author says [from Czech to English auto-translation...[
''PowerGood

Mainboard needs "PowerGood" signal. When all output voltages goes to stable, then PowerGood signal goes to +5V (logical one). PowerGood signal is usually connected to the RESET signal
