There is practically no chance of a repair procedure.  The whole
ceramic package is hermetically sealed and it would probably cost far
more than $800 to open it up, replace a pin, prepare the surfaces for
sealing again, and reseal all in a clean-room.  I'd advise your friend
to first look at the pin-out for the chip and see what that pin does.
(There's a chance it will be N/C -- no connection -- in which case you
are home free.)  If not, if it is a power supply pin, you may be able
to get away with the degraded supply.  Do you feel lucky?
