Replacing a laptop screen will be some of the hardest work you have ever done... don't try it unless you have a whole weekend you want to dedicate to it... not to mention I don't even know who goes around selling laptop panels...
Replacing it will also be fairly expensive, it might run anywhere between 600-800 bucks...
So my guess would be to just scrap it and get a new one... but ask around for some estimates first...
