Sorry, missing information. Coil voltages and diode mode - L8100 - 1.2v / 0.216 - L8102 - 0.9v / 0.089 - L7410 - 0v / 0.003 - L7430 - 0v / 0.004 - L7210 - 0v / 0.008 - L7230 - 0v / 0.007 - L7290 - 1 / 0.018 - L7030 - 12.4v / 0.457 - L6960 - 3.3v / 0.418

No error in DFU mode. It completes the revive and restore process. I have the S5 line voltages

Board is perfect, no oxidation or short. It has 20v and draws 0.2a from the source (without battery). Trackpad has click. In DFU mode, I tried Revive and Restore, both complete without error and Configurator gets padlocked. Audio card is perfect, but I tried to connect with it disconnected, it...

I figured it might be iGPU. Thanks a lot for the help.

Monterey installation was to get the firmware updated again. Tried with external SSD with El Capitan and High Sierra (Mac shuts down when loading system), Catalina (system starts and hangs on user), all with internal SSD disconnected. Yes, I used BIOS clean ME. The system works in safe mode...

Plate is perfect, I didn't find any oxidation. I've tried it and without success. - I put the board in another topcase. Discarding trackpad and cable, I/O board. - replaced the SSD - reinstalled system - tried with external SSD - I changed the BIOS The strange thing, when I changed the BIOS, I...

Yes, I have 3.3 in both lines.

PM_SLP_S4_L does not pulse

Meter does not change and PM_PWRBTN_L pulses when I activate SMC_ONOFF.

the board no longer pulls 1.8a. A similar Mac came in to change the battery, I took the opportunity to compare the coils in diode mode. Little difference, an example: the good board the L7211 appears 0.003, the bad board 0.007

I already tested it, it doesn't give any signal

I tested it without the J9600 and also tried it with another BIOS. Same problem. I don't have a board of this model that is good for comparing coils. I compared it with annotations from a flexbv boardview and they look OK.

Sorry, I put 0.2a and it's 0.02a. Yes, charger 87w and original. It only showed fast 1.8a without the battery. With the battery it was always 0.02a The board now no longer pulls to 1.8a. when I plug in the charger it shows 5v, 0.24a, in a second it changes to 20v and 0.02a

The logic board without oxidation. customer reported that it stopped working. It has 20v, pulls up to 1.8a and drops to 0.2a. I've seen this with a shorted SSD line, but I looked for a short on the board and didn't find it. CD3215 LDOs all normal. PPBus 12.6v PP3V3_G3H - 3v3 PP5v_S5 - 5v I...

PM_PWRBTN_L drops to 0v by pressing SMC_ONOFF_L. PM_SLP_S4_L only pulses when I press SMC_ONOFF_L. Values change with each test, had 0.5, 0.8, 1.5v

Yes, it has a drop. goes to 1.5v when I trigger SMC_ONOFF_L

Logic board in good condition. It has by SMC bypass, does not turn on. RTC_RESET_L - 3.26V PCH_INTRUDER_L - 3v (it was 1.5v, I replaced it with a 100k resistor) PCH_INTVRMEN - 2.5v PCH_DSWVRMEN_L - 2.4v PCH_SRTCRST_L - 3.26V PPBUS_G3H - 8.6v PP3V42_G3H - 3.4v PPVRTC_G3H - 3,3V PP5V_S5 - 5v...

looking everything under the microscope. I found that the U5860 is missing, it was ripped out with everything, pads and track. The customer reported that the Mac had never been opened. I will try to correct. Thanks a lot for the help.

correction, board is 820-00923.

Yes, another chassis works perfect. I tested the ALS, the automatic brightness works normally. The problem continues even with the battery disconnected.
