After multiple attempts, I still cant fix the major display issues on my iMac. Pink spots, Blotches, and lines through the screen. Apple replaced the LCD multiple times and still did not resolve the issue. They won't replace it, basically giving me B.S. about it not being their problem and they are saying that they can't give me the right graphics card for replacement(I ordered the ATI 4850 BTO 24in iMac and they want to give GT120). How can I get them to know my iMac is a Lemon and I desperately need a replacement?
