Thanks for the dump. The motherboard starts but no image. Today I'll replace the pch and write the result.

I replaced PCH and IT but no change. 3.3v 5v ok, no shortcut anywhere. RTC is in it. I give it 19v and it starts automatically and will restart. After 10 seconds the fan rises to 100%. Holding down the power button will turn off. I unplug the adapter, then plug it back in and do the same thing. I find that it has 1v on the PCH when off. The en2 pin on the NB689 has a 1v. Ic is on. This is not normal.
I would like to ask for schematic drawing and boardview.

Thanks.
