Hello All,
I've been following this topic for quite a while and wanted to post my experience.
I too had been experiencing the problems that everyone else here is having: horizontal lines, CMYK blocks, display black-outs, freezing, and the most annoying little burn spots on my display (presumably from overheating.) I bought my MacBook Pro 2GHz in July 2006 and did not purchase any sort of Apple Care. I started having the problems around November of 2008 and didn't think much of it. After it got worse I reinstalled OS X and then eventually still had the exact same problems, of course. I made several calls to Apple Customer Care and they all told me the same thing, go see a Genius and since I live in College Station, TX, I decided to put it off for a while. I installed SMC fan control and that seemed to help. Eventually I got fed up with it and decided to take my computer to the genius bar (early August of 2009.)
*Let me summarize at this point: My computer is 2 YEARS out of warranty, I have a dying logic board, and dark splotches on my display. Oh, that and the fact that I am NOT paying 800 to have my logic board replaced, forgot about that.*
So I went into the Apple Store in the Woodlands and sat down with a genius for about an hour and half and left with an agreement that it would be fixed for FREE, contingent upon me putting the original HD back in (I had done an upgrade.) I drove home to College Station, replaced my HD, and brought it back to the Woodlands. I received my computer back today (2 weeks later) and saw the most beautiful bill ever:
*Tier 4 Accidental Damage: $0.00*
*Labor: $0.00*
*And in the notes: Replaced logic board, Display.*
It's like a new computer!
Now, I didn't do anything terribly special to convince the Genius of the fact that I shouldn't pay for this repair, but I think a few things did help.
1) I was extremely polite. I told him that I knew it wasn't his fault and I'm sorry if I made it sound like I was blaming him. I apologized for making him miss his lunch break. I made small talk while he ran tests.
2) I wouldn't take "no" for an answer. About 5 seconds in he told me he couldn't do anything for me because I was out of warranty, to the tune of 2 years. I then explained that I was indeed out of warranty, but believed that this was a manufacturer's defect as opposed to user error. Eventually, I got him to admit that I had chosen a lemon, a defective computer. At that point, it was fairly simple.
3) I knew what I was talking about, as does everyone here. But don't attack them.
4) I shut up. I told him everything I knew, what I thought the problem was, and how I wasn't really responsible for this problem, and then I shut up. I was silent for about 3 or 4 minutes as he did tests, and it got pretty awkward. But sometimes, silence is incredibly powerful.
5) I was polite. He got paid the same amount whether he helped me or not, so what's in it for him? Why on earth would he feel inclined to help someone who is rude? Just be nice to the poor Geniuses.
6) I got lucky.
I hope this helps someone, but please know that Apple does take care of its customers. I am sitting here with a new logic board, display, and all my money still in my pocket to prove it.
Please feel free to ask any questions.
