I would only buy a screen that was made for a notebook of the same model as yours. The number of pins may be the same for many screens, but the function of the pins different. Notebook screens do not have any interface standard.
Replacing your screen is easy enough. It will generally cost less than $300. For help on the repair, look here:http://www.tomshardware.com/forum/53660-35-notebook-disassembly-hardware-repair-guide
