There are several Mosfets for each leg of the H bridge in the Victor. I find it hard to believe all the 'forward' mosfets could have burned out. But it is possible the controlling electronics in the Victor have failed.
Parts do fail. We use to staple all our failed parts to the wall in our Sparky area. After a few years we had quite a collection on the 'wall of death'.

Yes, we did calibrate the Victor to the factory default.
We have a lot of dead Victors (wrap it up in electrical tape to identify!), but this one has such a bizarre failure that we haven't labeled it dead... yet.
