Where is the short?
Is it the cable?  Repair it.
Is it at the output?  Check the diodes that do the rectification and the diode that is parallel to the output and protects from overvoltages to the load.  Sometimes is a zener diode.

If the short is at the input and blows the mains fuse then check the power mosfet, the bridge rectifier or the IC that controls the mosfet.

You generally don't bother, buy a new one.

If you want to bother then check the main filter capacitor, then the switching transistors, followed by the rectifier on the output stage, then the bridge on the primary side.
