hello everyone. I'm the proud owner of a 2.2ghz/2gb RAM Penryn MBP (2007) that is about to leave the AppleCare nest. I took it into the apple store to get a couple minor issues fixed before it expired--one of which included some spotting on the screen that I thought was accumulated dead pixels but which turned out to be some kind of pressure markings. To make a long story short, I convinced the geniuses to replace the display, which was a matte LG that had, apart from the marks' appearances, been fantastic with great color balance. Unfortunately, when I got my machine back the next day, I was horrified to discover that my screen had been replaced with a 9C6D Chi Mei display that looks very... blue. There's a blue cast to everything, and although I'm not sure the average user would notice it, I see it every time I look at the screen, no matter how I try to calibrate it. It's making me crazy and giving me a headache. Before I take it back to the Apple store, I wanted to have an open solicitation for advice. Does anyone have any further information about the 9C6D displays? do they have problems in general? has anyone else seen one? And how can I explain this to Apple? Like I said, it's not like everything is completely blue. It's more like a cast that I can't get rid of even if I cut half of the blue in the balance in calibration. I'm worried they won't see it or believe me. Thanks in advance. I hope someone's got something for me.
