Re: MacBook Pro 2017 A1706 820-00923 no power, low voltage PPBUS_G3H
Do you have a USB-C meter? look like you only having 5V on the DC-in. Check one of the CD3215 it could be bad or shorted.

A12179 820-01958 Missing EDP_BKLT_EN
I am working an a MBA 13 2020 that has no display. The MacBook power on but no display. After Checking on the backlight I found out that the EDP_BKL_EN was missing. And this power enable was coming from the PCH. So that means this MBA board is no chance to bring it back to life? any suggestion would really appreciate. Thanks, MobileXt

Macbook Pro 13 820-00840 PP3V3_G3H Problem
I'm working on a Macbook Pro 13 820-00840 that no physical water damage the macbook is clean. The problem was missing PP3V3_G3H power rail I replaced ISL9239 and U6990 and now stuck at 2.2v on PP3V3-G3H power rail I replaced all the component for the PP3V3_G3H Power rail and still have the same results. I replaced the U6990 5 times and still stuck @ 2.2V no short to ground. any idea what was wrong on this machine. Thanks
