Oops, I read the original post as about resistors, not fuses. To be honest,
there is no point to a fuse on a board like this anyway; they are designed
to be sacrificial, but if the board is not user-serviceable, what is the
sacrifice going to protect? In Edward's shoes I would seriously consider
using a bit of conducting epoxy to simply short whichever fuse is dead
(which can be discovered with a schematic and an ohmmeter).

All the SMT fuses I've seen were labeled right on the part. If not, you're
probably not going to find out and just need to buy a new system board.
There is, unfortunately, no way to measure a fuse, so even if I had one I
could pull parts from to measure, it wouldn't help.
If you do find out what value you need, I wouldn't attempt the replacement
without a Metcal hot tweezers.
Good luck,

Installing new small surface-mount parts on a multilayer PCB is hellishly

I'm sure the resistors are completely standard; once you know their specs,
you should be able to find replacements at any good electronics source,
like
Digikey or Mouser.
