Hello, I have this board with liquid damage and high corrosion U7701, U3210/20 board turned on but without backlight when removing U7701 it does not turn on only green LED and then orange and don't fan speed . I suspect a short but I can't find it.
thanks for all
any values:
PPBUS_G3H: 8,5v...
hi again, I replace C7025 but continuous with 1v at F7040 Maybe it doesn't replace Q7030735 correctly?
U7000
Pin1=15,5v
Pin2=15,9v
Pin3=0v
Pin9=0v
Pin12=3,44v
Pin13=3,4v
Pin14=0v
Pin15=0,03v
Pin17=0,58v

C3100 don't short and value 744 (other board 820-00244 C3100 value 1389)
remove C3100 LDO all 0v but now I don't have 5,2v in F3050...(strange)
do u want me to try a reballing of U3100? or replacement for another board?
thx
im replace Q7030/35 of other board with problem gpu
check C7025 value 556 and R7025 I check with 2 boards (once is work) 0,01 value scale ohms 200 and check for example R7022= 09,9
F7040 out a pin1 0.9v
Good morning, macbook in dfu mode restore load operating system and halfway (approximately) restart and cancel then I can see logo "padlock"
I try this 3 times and 2 cables usb-c genuine
cpu dead?
nice my problem is with D7005
now I have Pin2=16,5v but don't turn on and don't have led green
now I detect continuity in pin 21 and Q7035, maybe I could have reballed the U7000 wrong and this pin21 is playing dough?
