I have uneven lighting, as the screen goes to the right, its slighter darker than in the middle. i wonder if this would warrant a LED backlight/LCD panel replacement. I like 9C67 though because there's no yellow issue on it as many people report with the 9C68 Samsung model. How do you like the screen? i think just about every mbp i've seen has exhibited slightly non-uniform screens with slight backlight bleed. btw i have SR 2.2 that I got in october.
