Cant find any liquid on the board. At the start there was short on PPBUS and UB300 was getting hot. Replaced and short is gone but on that side got 5V and 0.25A. Just in case replaced CD3215 one more time but same issue. On another side 20V and around 1A. There is Apple logo, no progress bar...

Made a stupid mistake - was checking voltage DFR_TOUCH_RESET_L and flex was not connected. With flex connected got on R5103/1 1.78V and on R5103/2 1.77V

Dont have access to working board anymore. J5110 DFR_DISP_VSYNC = 0.512V DFR_DISP_INT 0.0V DFR_DISP_TE 0.0V DFR_DISP_RESET_L = 1.79V PP1V8_SLPS2RSW_DFR = 1.80V PP3V3_G3HSW_DFR = 3.34V In Diode mode: MIPI_DFR_CLK_CONN_FILT_P = 0.485V MIPI_DFR_CLK_CONN_FILT_N = 0.485V MIPI_DFR_DATA_CONN_FILT_P =...

Board was liquid damaged around J5100 Resistors around showing correct values. Diode on J5100 show same values like another board. No Touch Bar with brand new part. SPI_DFR_MISO_R = 1.68V DFR_TOUCH_INT_L = 1.73V DFR_LID_OPEN_L = 0.02V DFR_TOUCH_RESET_L = 0.058V PP1V8_SLPS2RSW_DFR = 1.80V...

Any more ideas?

Same error.

Error

yes

Yes, when tried "Revive" got error "Gave up waiting for device to transition from DFU state to DFU state.

All 1V1 LDOs was present. Removed one CD3215, checked SMC_USBC_INT_L and was still stable at 0V, removed another one and then I saw pulse/spike. Putted back second chip and again was flat 0V. Replaced it with new chip and all works fine. WOW - thank you very much for all ideas. That will help...

SMC_USBC_INT_L = 0V Checked that on R3038 and other side is PP3V3_G3H = 3.34V. R3038 got correct resistance.

PP1V8_SLPS2R = 1.8V not stable PP1V1_SLPS2R = 1.1V not stable PP0V8_SLPS2R = 0.8V not stable PPVDDCPU_AWAKE = 0.75V PPVDDCPUSRAM_AWAKE = 0.8V PP1V8_AWAKE = 1.8V PP1V2_AWAKE = 1.19V PP3V3_AWAKE = 3.22V All voltages above are not stable. Sorry but what mean 'SYM 1 OF 4'? Below are details about...

P_IN = 5.15V AUX_DET = 1.29V VDDA = 5.05V VDDA = 5.07V SMC_RST_IN = 0V EN_MVR - can't find that on that board, but I found EN_VR = 5.08V AUX_OK = 3.40V AMON = 0V BOM = 0V

W/ batt got 20V and 0A from charger. W/o batt got 5V and 0.044A from charger. PPBUS_G3H w/o batt = 0.23V (on F7000) PPBUS_G3H w/ batt = 10.3V PPBUS3_G3H got 0.420V in diode mode. All LDO's reading in diode mode are OK on all four CD3215's. PP3V3_G3H = 3.340V

Both lines got correct voltage but they are not stable.

Yes, L7690, and it is not stable 3.28V and after around 2 seconds drop to 0V. 3V3_G3H_RTC is stable.

PPBUS_G3H = 12.25V PPBUS_HS_CPU = 12.20V L7210/20/30 0.039V in diode mode. PP3V3_G3H = 3.28V PPVCC_NAND_SSD0 = 0V PP5V_G3S = 0V PP3V3_G3S = 0V PP1V8_G3S = 0V PPVCC_S0_CPU = 0V PP1V1_S3 = 0V PP0V6_S3 = 0V PP5V_S5_LDO - spike to around 5V and then drop, plus is every 2-3 seconds PPVIN_G3H_P5VG3S...

Replaced U7370 (SIC635) just in case and the same issue but when battery is connected there is 20V and 0A from charger - is there any hope?

Would like try to replace U7370 as it is liquid damaged and got a question: It is SIC535 and it will compatible with SIC532? Another questions about CPU mosfets: I see on boards SIC635, FDMF5804/08 - are they compatible or each of them are unique?

Thank you, I got that: L7211/21/31 2.2 L7330 11.0 L7410/20 4.1 LA640/50 2.1
