820-00165 PP1V05_S0 low

[dudipupan]

Hi there,

I got a 820-00165 with a liquid damage around U7600. I'm in S0 State but ALL_SYS_PWGD is missing because of low PP1V05_S0.
Already replaced U7600 and C/R/Q7630. Resistance to ground on PP1V05_S0 seems good (320 Omh).
Here are the voltages of U7600:
Pin 06 :1.8V
Pin 12: 5.1V
Pin 16: 3.3V
Pin 17: 0.0V
Already checked all traces and solders around U7600... they seem to be ok.

Any ideas what else could be the problem here?
Thanks and best regards
Dudi

Check R7611/12 and all surrounding traces/solders.
