In order to come to a definitive answer, it's definitely necessary to try outputting to an external monitor. If the external monitor looks fine while the laptop's screen is messed up, then the problem is either the screen, or more likely the screen cabling, and the solution is to replace the entire screen assembly, with cabling. You may be able to salvage the screen itself (inside the casing), if you want to go that far. And if the external video doesn't work or appears similarly messed up, then you've got a bad video chip and there's not much that can be done.

You could always reseat the connections related to video inside the laptop and on the back of the screen, in case something is just loose.
It also never hurts to remove extended memory, and reset the PMU and PRAM. I don't expect that would really help in this case, but I see stuff that surprises me daily, and doing that is always a good starting point when troubleshooting a machine.
