Order a replacement screen for your laptop! Screens for this laptop (and almost any other model) can be found at https://www.laptopscreen.com/.
Be careful to order the right type of screen! There are two types, LED and CCFL. If you aren't sure which type your laptop screen is, wait to order the screen until you reach step 7, so that you can verify what type your computer has.
Before working on your laptop, check the warranty terms. If the machine is still under warranty, working on it yourself may void the warranty.
Lift the plastic lid up to the back of the screen, and press them together so that lid now hinges with the screen
Be careful that the cables which run along the bottom inside edge of the lid are not squished by the screen when you bring the screen and lid together!
Boot up your laptop and check to see if the new screen is working- if not, go back to step 12 and ensure you reconnected the video cable correct and without damage
