Hi! I bought a white Macbook back in 2008, and in '09 I handed it over to my parents to use. Long story short, the screen is now buggered. A picture says more than words ever can, so have a look;
(Check out the tidy desktop!)
The top half of the screen is functional, yet the bottom half glitches out as you can see. I used to be able to wiggle the screen, find the right angle and get a normal picture but that is no longer possible. The rest of the laptop is fully functional.
Is this a screen issue or something else? I've found some services on ebay that'll replace the screen for a (relatively decent) fee, and was tempted to go for it. But I want to be 100% sure that it's the screen and not, say, a motherboard issue or something.
Thank you for any help!
