Welcome to AC!!
It wont turn on at all, or, it wont boot?
If it wont turn on, what happens when you put the charger in, nothing? If that is the case, then, you are probably SOL.
What methods have you used to contact the manufacturer. Phone? Email? Make sure to try all methods. If those don't work, where did you buy it? Did you try returning it? Even if you are past the window where you can return it to the store/website, it can't hurt to contact them. As they carry the product, they should be able to at least help you contact the manufacturer.
