Ok so I had a problem with the video card failing, and the warranty was extended due to this being a known issue, so I took it into my local Apple Store and left it with them for about 4 days so they could replace the logic board. I finally got it back last night and everything seemed to be working just fine, that was, until I loaded up a full screen movie and noticed something while the screen was completely black. Right in the middle of the screen there is a very faint and somewhat thick (half a cm) line that looks like a faded dark reddish color, and a few circular blotches near the bottom of the screen. Imagine it like this, you have photoshop open and you have a black canvas and you take your paintbrush tool and paint a red line and circles with the opacity at about 10%, that's kinda what it looks like. Now, I can't see it all with any other colors on the screen like in whites or whatever, nor does it show through normal usage. It really is only noticeable during completely black images with the backlight on. If the backlight is off, it doesn't show. So does anybody know why this is happening? I mean, I can't figure out if this is something to do with some sort of defect with the new graphics card in the computer or if one of the techs over at the Apple Store damaged my screen somehow. Could it be some of the lcd leaking on the inside?
