Tony, It may not be the screen thats at fault, well not the pixels anyway, looks like there are failing components on the screens driver board. (Not the graphics adapter, but the circuit board that drives all the pixels) If you can hook up an external monitor, this may help with determining where the problem lies.. If the Laptop is under warranty, return for repair or replacement, If not, then its still a tech repair job I would say, and maybe time for an upgrade

if the repairs are going to cost $$$
