820-00928 5v on port PPBUS 0V

[No-Clean]

This board did boost to 20V a few times and started up in my bench alone a few times but not it is back to the original problem, ports only take 5V and PPBUS stays at 0V, clean board.

R7020 5V in all pads

U7000 replaced already from same board just in case

Q7030 and Q7040 replaced and same.

Are you using 87W charger for sure?
Check how it is recognized in another MacBook.
Just in case, test with other known good 87W charger.

Yes OG 87w and OG cable, same thing with a different charger.

Checked U7000 resistors and diode mode around but all seem ok.

Also replaced U5000 but same thing.

If I leave the board alone for a long while the board will start but only that one time, if I unplug and plug again the problem comes back.
