Hi Dan and welcome to Electronics Point

I don't think there's anything wrong with that transformer. It looks like the circuit board has burnt up somehow, and deposited some black gunk on the wires on the underside of the transformer. The wire isn't damaged and show no signs of overheating itself.

You'll need to clean the circuit board and cut or grind out any material that's discoloured; even slightly. Take photos first so you know what needs to be connected to what.

Do you know what caused this problem? Is it possible that something dripped onto the board? What does the underside of the board look like?
