@mikejones16675 could be an LCD issue. Connect an external monitor and see if that works. You could also have backlight issues. A simple check for that would be to darken the room and turn the laptop on. Then use a flashlight and angle the light at the screen on different areas. You might make out some shadows, your desktop or see a slight grey color.
