Be aware, 1V1 LDO must appear only on the powered port.

Yes I tried them all one by one

Then you still have problems on USB-C areas.

CD3215 chips good for sure?
Possibly bad solders, broken traces...

 

[iFix]

Nothing that seems as a possible problem when checked under microscope all of them seem fine nothing broken in that area. C7651 was broken off complete but i returned it in place

D6902on pin 2 i have 5v and i don't have PM_EN_P3V3_G3H Enable signal which comes from U7000

 

[iFix]

I replaced U7000 i got the EN signal still stuck on 5v

 

[iFix]

The U7000 that i replaced was used and not good probably i found old stock new U7000 replaced it after i git the EN signal on U6903 but the final solution was D6902 and got 20v powers on now.

Disclaimer: No CD3215 were harmed during the repair ??

Thanks for the help

You didn't say missing 3V3_G3H on earlier posts.
I forgot to ask about it also...
