If its still under warranty they may replace it.
If not maybe worth popping it open to be sure, you should be able to tell if the fetts are gone by looking at them ,they have a kind of burnt bubble (proper technical term that) on them.
Or you maybe better off getting advive from Imull or one of the other proper technical chaps on here, they may even be able to repair it.
