And how exactly did you determine that the "EMC" blew?
Assuming you mean the mains noise filter section (X2 caps, Y2 caps and common-mode chokes), those things rarely (if ever) blow, and if they do, there's something waaaaaaay more wrong downstream.
Assuming you have a multimeter, you could start by "beeping out" the mains input to the power supply.
After replacing the fuse at least, it might've been a good idea to connect the mains through a "bulb tester", ie. an incandescent / tungsten 60-100w lightbulb wired in series, for current limiting. If it lights up bright, you know there's considerable current draw, but the bulb should drop enough voltage to not have anything damaged in the DUT itself.
