820-00840 liquid spill

[raainxx]

hi,
I'm working on an 820-00840 board now, this board have a liquid spill.
i clean it with ultrasonic and change some broken component (like C3891,C3890,C3892, U3890)
pp3v3_g3h: 3.4v
ppbus_g3h: 13.06v
all_sys_pwrgd: 3.22v
pp2v9_sysclk: 3.0v
pp3v1_rtc: 3.09v
pm_slp_s0_l: 3.3v
GTVR_FCCM: .022v
USB Mouse light flickers for literally .1 seconds then no activity.
CPU gets warm as normal, but no chime/boot/etc. Any ideas?
thanks

Possibly corroded balls/traces under CPU, or RAM.
A simple resistor/trace broken can also be the culprit.
Did you try known good BIOS?
Also check the board alone on the desk.

seems a bad hole broken, near CPU, i don't waste more time.
thanks
