Probably not outside of microchip.  I can't imagine a programmer verifying
at nominal voltage and the Vdd limits.  That would require 3 verification
passes.  Most programmers out there do only one.  A few professional
programmers like the PM3 and mine do two.  I don't know of a single
programmer that does three.

Consider the PIC not programmed of course.  You might want to try again, but
if it persists you have a bad PIC.  Certainly the PIC needs to be tossed.
Whether to toss or repair the product depends on the economic particulars.
