It was a liquid damage board, the spill was around q7130 area.
i have cleaned and replaced all components, there is a short on system side of l7130, i haven't looked into yet as i was trying to get ppbus before hunting that short, so long story short i have replaced all components including isl6259 but i still get 15.80 volts instead of 12.56 on pin 1 of l7130.
resistance between pin 17/18 and 27/28 is 3 and 20 ohms.
i have compared values to working board and pin 21 of isl have around .8 volts on working board and non working have 0 on it.
what else should i check?
