Smashed my blackberry, desperately need help. PLEASE!!?

the other day i knelt on my blackberry 8520. i heard the screen crack and then it just went white. now when i turn it on the screen is grey with two visible cracks on the screen, and one of the cracks cuts the corner off, leaving the corner white. there are two lines down the middle of the screen; a blue one and a red one. i just NEED some help with this, im lost without my blackberry. is this a simple lcd problem as i have ordered a new screen off the internet to change, or is it my actual blackberry. i presume if it was the actual blackberry it wouldnt even turn on. PLEASE, someone help me!!! i am desperate hahaaaa
