Hi there!
If you like it or not, the best way (i.e. not the easiest) is to take the point-to-point-diagramm. There must be a cn on the board for which the fuse is build on. Playing a little bit "Sherlock" then you see which part causes the blown fuse.

There is a shorted component in the power supply.Check the integrated components with heatsink whether it is good or not.

Check the power supply board if there is nothing shortage component like diode and check the varistor this is also protector for short circuit or you inserted not the same amperes of fuse.....is this 220 volts?
