Obviously, you let the smoke out.

Let me explain: all electronic circuits "feed" on smoke. When you purchase a new electronic device, it comes with a certain amount of smoke inside to feed all the hungry little bits. When you plug in the device, all you are doing is warming up the smoke to make it more palatable to the electronic doohickeys inside your device. When the smoke has been adequately heated, the electronic parts begin to do their part to make the device work, in the case of your light, they create light by shining it out of their bums.

Sometimes, if one isn't careful OR if the smoke containing vessels are somehow ruptured, the smoke is let out and the device ceases to work. You'll know if this is in fact the case as you will see the smoke come out of your device.

Hope you got a chuckle. Good luck with the repair/replacement.
