You might be
able to etch a 'patch' -- a small PCB that can be fitted
into a hole cut in the original and then joined up. It would be worth
doing that if the original PCB was SRBP (the replacement could be
glassfibre).
I've done just that. In a pinch, grid-board and some patience can work too
;)

Well, unless you know for sure that the area is indeed carbonized, and
that is causing a problem, you should leave it alone. Usually this only
causes problems for high voltage or highly sensitive parts of circuits. I
imagine something else took out that diode, which is still causing your
problems with the supply.
