I can see similar signals on display mux page , For example DP_DDI2_ML_C_P<0> .....DP_DDI2_ML_C_N<3> ,DP_DDI2_AUXCH_C_P / N , Will it make sense routing it to internal display? ;) Another question, Any idea about what activities take place by EDP_INT_AUX_P/N. If it is not dynamically driven...

It may be a stupid question... Is there any workaround for this signal? By wiring it from any of the USBC display data signals? Or only solution is to change motherboard?

The fan is slowly starting and then running at full speed, But still 0V at PPVCC_S0_CPU_REG. Should I close it or Is there something I can try?

Working fine with an external monitor, Internal display is not detecting, Tried connecting another internal display but still no back light or image. History - Coffee spilled Found corrosion on display connector (Not on logic board but on display board). Cleaned it up , Still no change

Thank you so much

Excellent, issue fixed ... It was not U5165 ,but one of the 10uF decoupling capacitor what was bad. You guys are simply awesome...

Removed the board and checked PP3V0_G3H_AVREF_SMC it is 0.143V

Ok I will do that, just a question, Could you help me with a disk image where I can load and run the hw monitor and HW sensor monitor?

If I am not wrong for posting HWmonitor I have to go through the entire steps attached below? https://hackintosher.com/guides/hwmonitor-hackintosh-guide/ If yes I don't think I can do it , Because the system is that slow :(

CPU usage is high , but I can't feel so much heat on CPU heatsink....

Even the screen brightness and touch bar brightness vary according to the flashlight I give. I have noticed the fan running when I run hardware diagnostic tests. But never during power ON/bootup/after bootup

Well, After reading more in the forum, Understood what I should do. The keyboard backlight is ON& OFF according to the flashlight I give on the webcam. Which means ALS is fine?

ALS check is not clear for me,I have tried FaceTime app, camera is ON and the green light also ON. But I have never seen the fans running for this unit... Am I followed the right step ? “Backlight screen and keyboard should react then “ what is that mean, could you describe bit more ?

Is it normal that the fans are not running while booting?

I don't have a working 170x series MacBook for testing, it is really slow when I boot from an external SSD (Bigsur) after removing the J9600 connector.

I have resoldered the backlight chip, Now when I start there is backlight ,,,, When I reboot no backlight. Once starts then it keeps working. Does it a software issue or I should resolder it again?
