a laptop screen is very easy to change
you can do a bit of a search on the net to try and find out what screen you have but the best method is to remove the one you have and get the make and part number
Used lcd's are readily available on ebay
To remove the screen it is just a case of prizing out the rubber plugs around the front bezel,under these you will find screws once these are removed the bezel will clip off the screen can then be detached and the two cables removed one video cable and one inverter cable
Do the ebay search on whoever makes the screen part number
unlikely to be a sony screen probably hitachi,toshiba or lg/philips
