Need more info really, if the resistor that's "blown" is wire wound you might be able to get an idea of its value by carefully breaking up the resistor and measuring the resistance of any intact wire lengths, another trick for open circuit unidentifiable wire wounds is to cut/file through the insulation be it enamel or whatever at a point equal to half its length to expose the wire, measure from that point to either end, you might get a reading, if so then double the value read.
