the plating burned off? OK, i'm accepting that fix as being A Good Idea™ but ... what? How does that happen? (As I've asked...) What is the cause of the burning?
Better minds than I can answer that question, but presumably it has to do with the large high voltages which are traveling across that pin and related components. If the C15 fails, there's little to resist the full charge passing through, hence the need to replace the C15 with a higher rated part than Apple originally chose.
