It looks as though the PCB discoloration may be caused by smoke emissions from within the failed rectifier, and possibly not carbonized the FR4 itself, which may bode well for fixing the circuit.
You might try just replacing the rectifier diodes and see what happens. Maybe try some parts with higher pulse current capacity...
That is a massive input filter cap and if the correct balance of components was not utilized, inrush current may be exceeding the rectifiers pulse current handling capacity.
If it is carbonized board I'd definitely want to carve out the compromised FR4 before fixing and re-using it since the the more carbonized it has become the leakier it will be. Not good for fire prevention when enough energy is present to heat the carbon path to ignition temps.
