Hello,

I'm currently in the process of repairing an A1466 (820-00165) logic board. The problem was that it wouldn't turn on. I have taken out the logic board and tried to troubleshoot the problem, but I am struggling as I don't have any guides or references on how to resolve this issue.

I connected the MagSafe lead with the DCPS and given the input from that to logic board, the led is glowing orange, I checked PPBUS_G3H it's ok, PP3V42_G3H is also ok, from here I don't know where to go.

I would greatly appreciate it if you could provide me with a step-by-step instruction on how to fix this issue. Thank you.

Does that mean to have 8.5V?
8.2V is not good at all.

Any history available?

Do you get 3V3_S5/SUS?
