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.
