This arrived with no liquid damage. PP3V3 and PPBUS_G3H were missing. Short found on C6906, replaced but PP3V3_G3H only 2.2V now and PPBUS_G3H still 0V

Replaced U7000 with new chip but still no change

D6902 pin 1 5v pin 2 0.120v pin 3 3.9v

To high difference over D6902, is probably damaged now.
Just in case, check diode mode to ground at C6906; compare with good board.
