I'm left with questions. Did someone add a plastic cover?
Does that pattern show on boot/powerup and all screens?
Does it show on the external?
Did this laptop suffer water or a dunking in a liquid?
Given the age, I think you need to go cheap on the repair. Ebay for a screen.
Hi, anyone knows what problem my screen has? Is it from the LED monitor or just the plastic cover on top of the monitor?
