All LDO diode mode readings are equal now, still no 20V and no BMC voltage.

All ports are missing that signal. Yes, PP3V3_G3H is present. Here we go: U3200: PP3V3_UPC_XB_LDO - 0.474 PP1V8_UPC_XB_LDOA - 0.495 PP1V8_UPC_XB_LDOD - 0.461 PP1V1_UPC_XB_LDO_BMC - 0.477 U3100: PP3V3_UPC_XA_LDO - 0.167 PP1V8_UPC_XA_LDOA - 0.496 PP1V8_UPC_XA_LDOD - 0.462 PP1V1_UPC_XA_LDO_BMC...

Hello. Got this board here that has bee cleaned by another store because of liquid damage, so I don't really know where original damage was. After some inspection I found a blown coil, L4004 was gone and so was its pin 1 trace, so I rebuilt it with a wire, there's no shorts I could find. As...

S5_PWRGD - 3.3V

Diode mode to GND on 3V3_S5G - 0.322 No enable signal. Also, PMIC_PGE signal is missing.

3V3_S5G - this is strange! 1.35V

PM_BATLOW_L - 3.3V

I tried replacing SMC again, took it from a donor board where I know SMC is working(the one I was trying to fix some days ago which got dead CPU), now I don't have 20V anymore. And yes, original 96W Apple charger with original cable. Will try putting back the other SMC again and check PM_BATLOW_L

First I tried replacing the PMIC and I lost PP3V3_S5 line. Then I reballed original chip and put it back. Got back 3v3_S5 but still no power draw

Yes, SMC is from same model. Will recall U7800 tomorrow and post results.

PCH_INTRUDER_L - 2.825V

Was what I did. I shorted SMC_ONOFF_L to GND with the tips of tweezers while measuring PM_PWRBTN_L and it didn't chance. Will check PCH_INTRUDER_L

PP3V1_RTC - 3.1V PCH_SRTCRST_L - 3.1V PPDCPRTC_PCH - 1.1V RTC_RESET_L - 3.1V For SMC_ONOFF_L I don't know if I understood well, but I tried to short it to and while measuring PM_PWRBTN_L signal and PM_PWRBTN_L did not get any pulses... It's steady 3.3V

Got this board here which was previously poked by another assistance. It got liquid damage(was cleaned before) and had no 20V. Replaced U3100 and SMC and got 20V back, but still no power. Compared side by side with another board from same model and cannot find any missing components. It does not...

Now a little spot on PCH is getting hot when I plug in charger. Think this one is gone.

Misteriously PP1V8_S5G line started pulling current(around 3,5A) from PSU, PCH got hot(not REALLY hot, but got hot to touch), after some time the current dropped to 0.5A and PCH stopped heating. Injected 1.2V again on PP1V_S5G_REG and it's pulling now 3.5A from PSU and PCH gets hot on that line...

I decided to measure resistance to GND on those lines instead of using diode mode. Black probe on GND, red probe on line. These are results: PP1V_S5G_REG - 2.8 ohms SSD_PWR_EN_CONN_L - 1.8 ohms PP1V8_S5G - 0.2 ohms

Run HWMONITOR to see what sensor is reporting high temperature/current

I raised voltage to 1.3V, it's pulling around 1,40 to 1,60 amps at this voltage. Still, nothing gets hot to touch although it seems PCH gets a little warm, but I think it's normal as it's getting power. Cables are not the problem, because if I put the GND cable on GND and the V+ cable also on...

R6123 was reading 203ohms. Replaced it and worked! Thanks!
