I have an A1260 (early 2008) Macbook Pro with (for what it's worth) an LG LCD screen (LP154WP2-TLA1). I have horizontal stripes that appear and flicker on the screen and change in appearance based on the positioning of the laptop screen (which makes me think it's the display cable, not the screen...?) and sometimes even go away completely. When the striping does not occur, the screen looks fine. What are the odds that I need to replace the LCD screen itself, the display cable, and/or the GPU? Thanks!
