PPVCC_S0_CPU

Came in for liquid damage repair, corrosion was around jtag connector and vp0r voltage sensor, cleaned and replaced few components and it started working,
clened it and put new thermal paste on cpu and when i tried to test it, nothing happened, so i measured few voltages and
ppbus was around 13.10
pp3v3 is 3.3
pp5v_5 is 0
pp3v3_s5 is 0 as well, checked enable signals for these rails and they are missing, can it be a bad pmic?
one thing i did stupidly was that its wifi antenna connector was ripped off by previous technician so i put new on, but somehow rf_antenna1 got shorted to ground but i don't think that line should kill a board
