Get a cheap tube or LCD monitor. Replacement notebook display panels (if available and affordable) are fairly involved to replace even for experienced geeks and require a good eal of dis-assembly.
You can have almost anything for a price. Unfortunately that price is almost always too high for used laptops. My wife had her work laptop screen replaced and it was $700. Not worth it for an individual. You can get new laptops for just a little more.
I have “repaired” LCD panels by buying the same laptop listed “for parts” off of eBay and replacing things. Taking apart laptops and putting them back together isn’t always easy (some makers like to hide screws in really strange places). Plastic ribbon cables are especially easy to break. Not for the PC novice but it’s doable and fun (well, for me)!
(Then since I have parts of two laptops lying around, I buy a third one in order to get a 2nd working laptop, and then…)
