The board starts, however, after 30 seconds shutdown.
I Already check all the rails and the bad one i guess is PP5V S0.
PP5V S0 - 4.0V and sometimes 3.9V

The board is very clean, like a new.

Any hint from here?

Yes, liquid (milk) damage / wont turn on.
Around SMC looks fine. Actually the whole board looks fine.

I still don't know if by "start" you mean it chimes and displays a picture. Was this thing touched before it got to you?

and what about this: PP5V S0 - 4.0V and sometimes 3.9V ? This would cause shutdowns if 5V_S0 is not stable of course.

Yes, i know, that's why im here trying to figure out.
PP5V_S0 needs to be 5V, right? I don't get any 5V there. Always 4 or 3.9V
