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
