820-00281-A stuck on 5v .02a


I have a liquid damaged board stuck at 5v. U3200 whats cycling on usb meter all other were 5v constant. I replaced U3200 and all are stable 5v. I check for shorts/diode reading on all 4 CD3215's all were around the ,400 mark. I checked the ldos from all 4 and all are present except LDO_BMC 1.1v on u3200 and U3100.
3V3_G3H is present.
PPBUS_G3H is 0v diode reading .395.
Im not sure where to look next as I cannot find any obvious shorts.

--Just read a thread there similar. Going to replace both U3200/3100 and see.
