Computer screen turning green then black..

Hello,
My hp pavilion dv6-2250s entertainment note book was dropped about 5 inches and landed on a soft surface..I plugged it in and about 5 minuets later I turned It on but the windows screen was green then will turn black.. I took the battery out and did the while turn on power cable but the screen turned white then turned black again... Please help!!!!! My dad is going to kill me!!!! (just kidding) no I have shut off and strayed it back up and it has shown the starting windows screen then a green screen and now a black screen again..
