Unfortunately, your options are limited, but you can try removing the battery, making sure all accessible parts (hard drive, ram) are seated properly, but more than likely either the connection from the screen to the laptop is damaged, or something inside the laptop, such as the video card are damanged. You can try plugging an external monitor into the VGA port, it may give you a display right off the boot. fyi, if the laptops worth it, and the video card turns out to be the problem, you can install a different one, but it will cost bucks.
