i just got my macbook pro back (2.2 C2D 15" LED Glossy) from being repaired - new logic board (i think), and a new screen. the screen looks great, except when you have it on the lowest brightness setting or two. it gets these strange bands of light. i took a pic so you can see what i'm talking about. Is this normal? I don't think my old screen did this. It's not a huge deal because I typically have the screen bright enough that it doesn't happen.
