820-00840 no power

[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

Check U7650 voltage, pins 23, 12, 13, 21, 22.
Also post U7890 voltages.

 

[PPVCC_S0_CPU]

Pin 12 is 0
pin 21 is 0
pin 23 is 13.10 volts

u7890 only pin 6 have 3.3, rest are 0.
i will post voltages on pin 13 and 22 of u7650 on Monday

No more voltages needed from U7650.
U7800 doesn't send enable signals to its pins 12 and 21.

Do you get SMC_PM_G2_EN?
Put good flux and reflow U7800.
Check its basic powers and signals...

Managed to turn it on, everything works fine,but there is no voltage on ppvccgt_s0g_ph3 ,ph2 and ph1.
is it supposed to be like that?? Machine is booting and i can use it.
