I have to disagree with the last statement.  The Apple repair facilities
that I have dealt with are authorized only to do board swaps for power
supply failures of this type.  My own experience has been that the
replacement boards fail just as often as the originals (which is far too
often).

I try to avoid Apple repair facilities.  I have been sending in our toasted
Pluses and 512s only when I could not fix them by resoldering joints on
the P.S./video board.  Now that I know the replacement boards are no better,
in the future I will probably use third party sources for parts and
replacement boards.
