This is a switch mode power supply with all the failure modes that that
implies :-)

I'd start by checking the mains bridge rectifier (actually used as a pair
of diodes in a voltage doubler circuit on 110V mains), the mains
smoothing capacitors (820uF?) and the BUV47 chopper transistor. If
the last is short-circut then it's very possible it was damaged by a
fault elsewhere in the PSU.
