Problem with acer screen

I doubt if the store or the manufacturer will replace accidental damage free but I would approach them for a solution unless you have experience of dismantling laptops. You can meanwhile use an external monitor, I'd guess, as it sounds like physical damage to the laptop screen, not a problem with the motherboard.

If you bought it at say Best Buy or Future Shop and bought the extra warranty you might be able to get a replacement or the laptop fixed.
There are very few laptops made that can take a drop other than some Dells and the Panasonic Toughbooks.
You can probably get a new screen from acer but it'll probably cost almost as much as you paid for the whole laptop....so.....
Hope this helps...JQ
