820-3115

Hi.

I have this board 820-3115 with no power and no green light I have measured no shorts, and the voltage reached Q7085 pin1,2,3. I have replaced U7000 and now I get the green light and only one time the fan span and it now stays on a green light, but I can see it it's blinking a bit...

We need some basic voltage readings from the MLB.

Did you test SMC bypass mode?

Yes doesn't wanna power on directly, i get the power pads voltage and when pressed it goes down and comes back
