No liquid. Not a popped cap.

PPBUS_G3H 8.6V

First noticed S5 rails were 0.5V.
Checked EN 3v3 and 5V S5 all fine.
Tried Q7520 and Q7560 and U7501 That's when I notice PPBUS_S5_HS_OTHER_ISN is shorted to ground. No visible signs of bad caps.
Plugged it up to PSU 8V @3A and nothing is burning my finger. No caps, nothing.

Ideas please?
