Hi!
I would like to ask for assistance in a 820-00840-A board. I'm more like into iPhone repair but I had some success in older Macbook repairs. This is not a customer board, it is for me to entertain myself in this hard covid times...
I think I found a rabbit hole but I would like to ask for some guidance, and please be very clear and lucid with me, also with patience. Thank you.
HIstory: It is water damaged.
C7748 was shorted so I removed it.
ppbus_g3h_cpu steady 13.05V
ppbus_g3h steady 13.05V
pp3v3_s0 0V .170 in diode mode
pm_en_p3v3s0 0V
From the power supply:
19.9V
0.04-0.06A
0.03-0.08A
Where should I look next?
Thank you for your time.
