yes a tried to restore with another T2 Mac and apple configurator but I got an error, the one I sent you in the photo. I had to remove some caps that had corrosion damage C9592 C9593 C9081 and I haven´t put them back because I do not have these cap at this time Do you think the failure could be...

what can i do in this case?

Yes i have voltage in all the ssd coils

Yes, it recognizes it in DFU, I tried to restore the system but it gives me an error.

PPBUS_G3H 12.62V 3V3_G3H_RTC 3.383V

L9020 0.156V L9030 0.325V L9080 0.318V

Hello I got a Macbook Pro with liquid damage in the sectors L9021 C9081 C9593 C9592 The damage is only on the edges of the motherboard I did a cleaning but the Mac does not turn on, this is the first time that I work with this motherboard and I am lost, I do not know where to start

now it's working :D What do you recommend me to do now?

RTC_RESET_L 3.3V PCH_SRTCRST_L 3.3V PCH_INTRUDER_L 3.0V PCH_INTVRMEN 3.0V

effectively when I activate SMC_ONOFF_L the pulse is seen in PM_PWRBTN_L but not in PM_RSMRST_L PCH_DSWVRMEN 3.3V PM_DSW_PWRGD 3.4V PM_BATLOW_L 3.3V 1V05_SUS 1.05V how are they measured of the 4 PCH's RTC signals?

PM_SLP_S4_L has 0V and does nothing when SMC_ONOFF_L is activated

R8133 it´s ok i changed u8130 and now it gives me these values PIN 1 3.3V PIN 2 3.3V PIN 3 1.4V PIN 4 3.2V PIN 6 3.2V still does not turn on

Pin 1 3.3V Pin 2 3.3V Pin 3 0.361V Pin 4 3.2V Pin 6 0V

SMC_ADAPTER_EN 3.3V PM_PWRBTN_L 3.4V PM_RSMRST_L 0V SMC_ONOFF_L 3.4V Drop pulse 3.4V to 0.352V when SMC_ONOFF_L isTrigger

PP3v3_SUS present PP3v3_S5 present I don´t know if its normal but the line P3v3_S5_Comp2 have 2.2V

i have 8.57 V in PPBUS_G3H with F7140 in place.

Thank you for your answer but i am a little confused, in Rossmann Repair Training Guide it says On Macbook Airs and old Macbook Pro 17” PPBUS_G3H is 8.5v when the SMC is able to communicate with the ISL, 8.16v when the SMC cannot. On Macbook Pros PPBUS_G3H is 12.56v when the SMC is able...

with F7140 removed C7140 = 8.56 V R7113 is good All components and traces related to pins 5, 7 and 8 are good.

sorry, I edited the answer with correct information Diode mode PPBUS_g3h = 0.122V Resistance between Pins 17/18 = 3.2 ohm Resistance between Pins 27/28 = 20 ohm R7121 = 10 ohm R7122 = 10.3 ohm R7151 = 2.5 ohm R7152 = 0.2 ohm

Thanks for the welcome, I am very excited as I have experience repairing iPhone and I am just entering the world of Mac PPBUS_g3h 0.122 Resistance between Pins 17/18 = 3.2 ohm Resistance between Pins 27/28 = 20 ohm
