I have a 2.4 Ghz Penryn 15.4 inch Macbook Pro that I got about a year ago. I just recently started noticing that when I move the screen of the Macbook Pro forward, there is a thin line that is on the left edge of the screen that is sometimes blue, light blue, green, white, etc. It only happens when I move the screen forward, not backwards. It goes away immediately after I stop moving the display. Is this a problem? I will post a picture of what it looks like below this. What do you guys think the problem could be? My one year apple care expires in about a week. Should I get it checked out? Thanks.
