Hi,
Got this old board with some whater damage near CPU area. There is no green light. Fans spin with SMC BYPASS but no image no sound not booting.
Getting this values on main rails:
PPBUS_G3H 8.41V
PPBUS_CPU_IMVP_ISNS 8.41V
PPDCIN_G3H 17.04V
PP3V42_G3H 3.42V
PP3V3_S5 3.3V
The only thing i noticed it that on U7000 the resistance between 27/28 is 21.9 and 17/18 is 21.5 too. I know for ISL 6529 second value mst be about 3ohm but seems that this one (ISL6258...) is 21 both. ANyway changed it and same things happening.
Any suggestion?
