I cannot see the picture, but is it a switch mode device or a good old
analogue supply?
If the latter the most common fault is the bridge rectifiers which are
commonly under specified for spikes in current etc.

If its swwitch mode then it might be possible to get a new module, but I've
seenin the past that companies have cut costs by fitting a soldered in fuse
as of course they never blow do they? :-)

Is the company that made the device still around?

The picture only shows a section of the board- 4 diodes (presumably a
bridge rectifier), and what looks like a space for a PCB fuseholder with
a soldered-in fuse in it's place that looks like it has exploded.
