Suddenly it stopped. No light no nothing?

A lot of gadgets have snap-in cabinets, because they're cheap and easy to assemble, and stay together pretty well. Get a thin screwdriver and pry around until you locate where they are.

You might find a fuse inside, or a fusible resistor. That doesn't mean that when you replace it, it will work again, but it's worth a try. I sometimes use an incandescent bulb in series with the AC line to try things that might be shorted out. If it is, the light will light up and protect yet another fuse.
