Hey Brent,
Did it happen to get physically hit with anything, or dropped? Other than replacing the LCD Screen itself you could try a few things. [br]

-You can try updating your graphic driver.
-Make sure you are on the native resolution.
-You can try the built in troubleshooter, but we all know how that usually goes.
A couple questions: [br]
Do the lines appear in the BIOS? Or only when it is fully booted? If not try a clean boot. This would at least help in determining if the screen is junk.
If you apply slight pressure to the screen do the colors change? If so that is usualy a good sign it is the screen itself.
Hope this helps.
