try plugging it into a diffrent outlet, one that you know works. if it has a seprate power supply cord try it on a cable you know to be fine. if that doesnt work then test the plug fuse by putting it in the plug of an applnce that you know works. if it still doesnt work then take it apart(warning- this will void the warranty!) and find the internal mains fuse on the power supply board. test that too. failing that the power supply may be blown. take it to a electrical repair shop or if your good with electrics try and fix it yourself. thats the first things i would try.
