I get pp3v3_s4 but 3v3_s3 is low .400v now i assumed it was smc so i switched it out issue persist odd thing is i did get it to power on once by using power on pads. I have had no luck doing so again. Smc_on_off_L stays at a constant 3.4v after using power on pads not sure if thats the issue...

pp3v3_s4 still .600v and drops.
board wont turn on and had very noticeable water damage. replaced whatever was badly damaged and retraced some areas. i get a green light on charger.
pp3v3_s4=.600v
