I recently found myself in a situation where the screen for the Mac Book Pro I had given my son was broken. Several years ago when I used to look at replacement screens they ranged between $300 – $500 a piece. I guess now the technology has matured because you can purchase screens for under $100. I went to laptopscreen.com from a Google search. The company has many screens available; I just needed to know the model number of my laptop and I found different screens to purchase. The site also has a lot of information – I had purchased my Mac Book Pro from Best Buy with the 1680 x 1050 screen not the 1920 x 1200 screen. The site explained that you could not replace one screen with another because they used different backlight methods.
Also the site has many YouTube videos showing you how to replace screens on different laptops. Be careful though – I followed a video for a Mac Book Pro 15″ model which was mostly the same, but had some subtle differences like extra screws and cables in different places. All in all I was pleased with my experience with this vendor and would do business with them again. They packaged the replacement screen well, the price was under $100 for the screen, and after installation the screen works great. Plus they give you a warranty on the screen.
