[SOLVED]820-00875 not turning on

I have this new 2016 machine(non-touchbar version) that had no liquid damage at all but won't turn on at all.

I haven't worked on these models but I did check out some of Louis' videos on this model.
I am only getting around 5v on PP20V_USBC_XA_VBUS. I believe Louis said if you only get 5v you need to check PP3v3_G3h. I don't get any voltage on PP3V3_G3H and there is no short on that line.
I get 0v on R3000/01 but I was getting 3.3v on C3208/3108 depending on which port the charger was plugged in.

F3000/3010 are working correctly and R5320/21/22 all measured the correct resistance.
0v on L5001/C5001.

Also, I am using a genuine apple charger.

I'm in the US but would the same apply so I can give this back to the customer and let him know?

If not, is there anything else I could do to fix this myself?

R6991 had 0v on both sides and had the correct resistance. You said D6901 but that doesnt exist so I think you meant D6905.
D6905 had 5.2v on pins 2/3 and 0v on pin 1

I get 5v on Pin 2 of U6990 and 0v on the enable Pin 2

Should I try replacing the U7000 chip?
