Back four-plus years ago, while I was jobless and almost-broke, my laptop's screen died on me. I couldn't afford to get it repaired by anybody, couldn't afford to replace it, but I was able to afford a used screen on eBay. I ended up learning a lot about my computer's innards as a result of figuring out how to open up the lid and swap out the screens... and I had fun for ages after that tweaking and fixing the machine until it finally died permanently.

*Gives you a big thumbs up!* It's a nervewracking step but if it works you're going to be feeling your power for years to come.
