Bought it yesterday, in couple of days will try. but what exactly generate this line BKLT_KEYB1?

Yeah, it is disabled when cover sensor, so it seems to work

Hi, Water damaged mac. PPVOUT_S0_KBDBKLT 5V BUt i compared with good working and see that BKLT_KEYB1 and BKLT_KEYB2 goes to 6-7 Volts when cover sensor near camera on display. But on this one it stais 0. Macos activated up down option for keyboard light control but there is no light...

"higher pulses" you mean the highest value of pp3v3_sus?

pp3v3 s3 and s0 are pulsing 0.5-0.8V and all other rails s0 and s3 pulsing too. Right now i am without o-scope :-(

ALL_SYS_PWRGD and pins 7 and 3 not pulsing. Removed Q8150 and the only difference is that after it is pulsin between 0.9 and 1.2 NO corrosion under U1950, but changed it anyway, now ALL_SYS_PWRGD is pulsing very lightly 0.00-0,002V ( dont know if this information is useful or not)

Reballed and sames happening. Exactly same. Change SMC?

SMC By pass not turning on Right now trying reball smc because i see that also there is issue with pm_slp_s5_l. Will back once finish

Got this board with water damage near U6100. Changed U7600, U6101, U7400 and some small components near that had wrong values. Now all main rails are ok, but all rails near efi chip are pulsing from 1.1 to 1.4 V. Board is trying to enter S0 and all S0 rails are pulsing (Ex: 3v3_S0 is...

No water damage, nothing bad on board Mains rails are ok PPBUS, 5V and 3.3V of s5 are ok. RTC also is 3.3. All_SYS is 0 but i cant find out why it is 0. All rails are present SMC_LID 2,6 is ok?

may be getting hot wasnt exact description. It is getting warm. What can i check to be sure if it is or not T2?

I can confirm that we are talking about J6100. Also can confirm that T2 is getting warm-hot does warm means is it ok=? is there any way to retrieve data fromt that mac?

Anything to do with t2?

So it must be reprogrammed or board is dead? P.S. will confirm tomorrow if j6100

I have tried with and without audio board. Same result

Usb get 19V and goes up to 1.27Amps. Board getting warm near U3900 area. No USB activity, no image external internal, caps button not turning on so my guess board is not entering S0 SMC LID 1.6V Any common issue with that f----ing T2 boards? There was liquid damage on sound board, after...

it was U7000. Reballed again and working fine. Thank you

Reballed but something very strange happening. Heating u7000 for couple second to 100 degrees make board starts. When it is completly cold it doesnt start. U7000 is dead or about to die? I am out now will post voltages tomorrow, but what i think about that?

Get 5V at R7020 PP3V3_G3H is generated by U7000? Any idea what it can cause board starting when heat up u3100 area ( just sometimes) Autoreply. It is U7000 what make board start when heat up. Will reball it now

No water damage, no history of any strange things. PPDCIN_G3H - 5. 2V PPBUS - 0.2V PP5V_S5 - 0V PP3V3_G3H -0 V PP3V3_S5 - 0 V LDO on both CD3215 are ok. WHen i heat up U3100 are it starts sometimes (not always). ALready tried to change CD3215 and stil not booting
