So, i had my revlon mirror stood on the desk infront of the acer computer when i knocked the desk and the computer landed on the mirror face down, the plug had came out so the computer wouldnt turn n, but once the engine started again there was a huge crack on the inside of the screen at the very top causing two lines to cover most of the background. 1 going straight down the screen, and the other crossing diagonally at the top. When i leave the computer running without typing anything it flashes white from time to time. I was just wandering if you could maybe give me an estimate price of how much it would cost to be repaired by a professional?
