Does the screen self-test run correctly? Hold D through powerup.

That would leave a bad video cable or a bad GPU.  If the system isn't a touchscreen, replace the wiring harness that connects the screen to the mainboard.  If it is a touchscreen, that's not possible - you'll need to replace the display panel (and if that's not the issue, it may still require a mainboard replacement if the GPU turns out to be bad).
