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

Board got very small liquid damage on U7370 and U7210 :( an on U6300, C3980, CB701 PPBUS_G3H on F7000 got 0.14V and 0.420V in diode mode. Big coils 0.001V in diode mode and 2 Ohm resistance to ground. PP3V3_G3H = 3.40V Removed F7000/1 and on pad 1 got 0.14V Any idea where to start?

Board was cool. Thank you very much for all those details - that will help a lot in the future tests and repairs :)

PPBUS_G3H got now 0.111V in diode mode.

Big coils 0.001V in diode mode and 2.4Ohm resistance to ground. L9080 0.03V in diode mode. 3V3_G3H_RTC 0.401V in diode mode - checked on R6935. Same behaviour on all ports. Noticed a solder ball on the edge Q3100 and D3301. LDOs on U3100 shows correct readings in diode mode.

5V and 0.035A from charger (96W genuine charger) There is no liquid damage on the board. PPBUS_G3H on F7000 got 0.350V (0.030V in diode mode so it is too low). Removed F7000 and F7001 and on pad 1 of F70001/1 got 1.3V (it is low because it got only 5V on PPDCIN_G3H?) and 0.515V in diode mode)...

Cant find any liquid - all in great condition. On charger 20V 0.08A (genuine 96W charger) PPBUS_G3H 12.62V PPBUS_HS_CPU 12.60V PPBUS_HS_GPU 12.60V PPBUS_HS_OTH5V 12.60V PPBUS_HS_3V3G3H_T 12.30V PPBUS_HS_3V3G3HRTC_X - 12.60V PP1V8_G3S 1.78V PP5V_G3S 5.12V PP3V3_G3H 3.34V PPVCC_S0_CPU 0.0V...

Board with previous work done. It is detected in DFU. Had a try a few time to finish DFU because there was some errors during restore. Now during downloading from internet recovery there is error -2003F I noticed power button won't turn on machine but charger is connected then I can turn of...

Thank you for that tool - that will help for sure. DP_INT_HPD in diode mode is fine but when board turned with screen connected it is low at 0.002V.

Board is liquid damaged with previous repair attempt. LCD connector on display board was damaged. Replaced and display assembly has been tested on another machine and it is working but cant be visible by clients board. Checked and pin 4 and 6 on J8500 was bend so replaced J8500 and display...

2informaticos - no internet recovery, no image just backlight. Maybe did not pass that as there was a chime and audio IC was a issue tcampbell34 - wow it works. Maaany thanks for help and that idea. That explains everything :)

Data saved but no luck with restore. Looks like restore passed but there is quarter fan spin, backlight on display (no data) and reboot every 20-30 seconds. board is fitted in the device and even with lid closed CPU is warm and on thermal camera looks like it is in boot loop.

Cant find any liquid or corrosion. I see display assembly has been replaced. Touchbar works but as soon it is touched it turns off but is back after a few seconds. Tested with another touch bar and small board and the issue s the same. Any idea where to start?

Cant find any liquid damage on the board. When charger connected to it freeze and restarts with Kernel Panic. Sometimes it charge battery without any reason but when cable is removed got blanks screen and restart with kernel panic. Tested with two new USB C ports and with two 96W original...

In diode mode: SPKRAMP_RESET_L 0.393V SPKRAMP_INT_L 0.392V

Audio board and flex had liquid damage and MacBook wont turn on. Flex and board replaced and boot but there is no audio. Tested with three audio boards and flexes. There is in setting output device. When press vol up/down I see it on screen. Mic works fine. Audio works fine via hedphone jask...

Cant find any liquid damage. Removed board and connected charger and on thermal camera U7710 was warm. Found short to ground on PP5VG3S_EDRAMVCC and PP5VG3S_EDRAMPVCC. Replaced U7710, short is gone and got 5.10V on both lines. With battery connected it take 2.25A from charger. With board only...
