find an online store that sells screens for laptops, open your laptop's screen bezel and check for id/make/model numbers for the screen
find someone on ebay/craigslist with the same laptop that is broken (ie motherboard is fried) and change screens (you would also have some extra spare parts as well)
getting a new laptop and an external enclosure for the current laptop's hard drive to get the data off of it
most laptops aren't worth putting the money into replacing the screen
