How do I replace the LCD screen on my HP Pavillion dv2715nr laptop?

The screen on my laptop goes back and forth between being just fine to having lines all over. After some research, I found that it most likely is a problem with the LCD screen. It is an HP Pavillion dv2715nr, model #KC453UA. I found a screen online that I can purchase but would like to replace it myself. Anyone out there that can give me some instruction?
