The likely reason is a dead electrolytic in the PS - the PS itself being

simply replacing the lot, but make sure you get suitably rated ones.

Not if it's blowing fuses - failure to start is a very common fault
caused by a dead small electrolytic in the startup supply, but
fuse-blowing is more likely to be the switching transistor failing short
or an output overload.

It's only guessing, but the SMPS on my video did exactly this - take the
input fuse - and it was a cap. Of course other things can fail too.
Schottky diodes and opto-couples are another favourite.
