PN5V7_LCM_AVDDN_CONN typically gives an OL reading or ~1.500V. Obviously an OL reading is not indicative of a short, on the contrary, it represents an open circuit.

Your VCC_MAIN reading seems a bit low to me, indicating some short somewhere downstream causing issues. Check the other PP signals on Chestnut (PP5V7 LCM and SAGE) as well as the BOOST line. Check them in diode mode first to see if any are shorted.

The 5C is a horrible device to work on :-(.
