Macbook A1181 wont turn on

[luke10050]

Hey guys, I recently received a macbook that will not turn on, turns out the tantalum capacitor near isl6263 had spontaneously combusted, anyone have any idea how to fix this one? Seems like it does some kind of filtering for the isl chip, the board also emits a barely noticeable high pitched whine near the single SMT poly cap. Can anyone identify the rating of that capacitor? From what I read of some half complete specs it looks like a 0.033uF tantalum.
