How to install Leopard on a Apple laptop with a broken LCD:I used an external monitor which required me to purchase a mini DVI to VGA adapter ($19 at Best Buy) in order to connect to my old CRT. Once I booted the computer to the Leopard DVD the Apple display drivers would load and default to the primary and broken LCD therefore I could not read any of the installation instructions. The trick is to close the top of the computer as soon as you power on the laptop in order to cause the Apple drivers to default to the external monitor. This method works every time but only after too much time spent with trial and error figuring it out.
