How can I troubleshoot my 17" MacBook Pro display?
Posted on 2009-12-24
I have a 17" MacBook Pro that is exhibiting horizontal lines across the bottom half of the screen. If I move the display, the lines move and change, and eventually, they will disappear. If I close the display, it stays fixed, but if closed for a prolonged period, the lines return. Connecting an external monitor shows no lines, and the built-in display seems to be lit well, so I don't think it's the display itself. The external monitor working well leads me to think the graphics adapter is working as well.
What could be the issue? The inverter? Any ideas or suggestions will be greatly appreciated.
