Board was messed with somewhere else and I have no history.

PPBUS is 1V

U7100, Q7130 and Q7155 I replaced but same problem

U7100 Resistance between 17/18 is 3 Ohm , resistance on 27/28 is 20 Ohm, this was bad before but I fixed it by replacing R7121/22 same problem

Removing F7140 gives me 1V at R7150

PP3v42_G3H is fine at 3.4V

27 Diode to ground 600 I did check that before the creating the post and it was fine.

Replacing Q7180 did the trick, thanks!
