Screen Burn! Can I Fix it Without Destroying Everything?

***DISCLAIMER*** I have no idea what I'm doing. Do NOT copy what I do. I'm revisiting the Game Boy Advance SP AGS-001 from the ebay lot. I've replaced the battery and everything seems to be working so far, except the screen is burned. I'm going to try to replace the polarizing film, but I've never done this before.
