820-000165A - no light on the charger and no power

Don't make confusion between turning on and booting.
If CPU and other chips get hot, board should turn on; not booting, of course.

So, tell us which big coils get voltage?

L7320 1,8V
L7310 1,8V
L7630 1,05V
L7430 1,02V
L7560 1,2V
L7520 5,1V
L7130 8,56V
L3095 0V
L7750 5,1V
L2920 1,0V

OK, so you get even VCORE.
PLT_RESET_L goes high?

And please, confirm if you have or not USB activity!!!
Use a pendrive, as in mentioned thread.

I have 3,3V on Pin 2 of U2071

I really don't want to bother you again about USB activity; seems to be imposible to get a correct reply from you .
This is last post where I mention this.
I asked about USB activity, not power!!!
Even left a thread about how to check that, I cannot test YOUR board myself.

Sorry for misunderstanding. I just wasn't patiened enough

So the machine works now?
What was the problem?

Last steps were: replaced the SMC from matching board, no change. replaced U7100 and got proper PPBUS. Plugged EL Capitan stick in and got an image. All working well now. I was to worried about stuck amperage. The SMC I took off bubbled so was faulty from the beginning
