Mickey: macbook pro A2251, has 20v but very low amps, won't turn on

So i have this macbook, It won't turn on. it has the 12v rail present and is showing 20v when plugged into a charger, but there are shorts on pp3v3, specifically the caps i have circled in the photo of the schematics. they are both still short when the u7700 chip is removed. i'm a bit lost for what to do next. i've tried volt injection but i cannot get anything to show up. Anybody got any tips
Cheers
