could be the LCD display, or possibly the graphic card. Perhaps backlight related, but I'd only suspect that if the stripes were NOT confined to exact pixel-aligned lines.
a couple questions and debugging ideas:
1) are the striped always fixed in the same position? or do the come and go depending on what's displayed?
2) do they go the entire height of the display, right to both top & bottom edges?
3) what happens if you change the screen resolution, in System Preferences/Displays - are the lines in the same physical position or do they "move" with the display image?
4) if you take a screenshot (Cmd-Shift-3), do the lines appear in the screenshot, or not?
the above might give some clues if it's graphics card/graphics memory related or the LCD screen.
