Hi all, I've got a 27" iMac 3.06ghz. Was originally purchased via an apple reseller in February this year. I am the 2nd owner, however I have the original sales receipt. The screen definitely has a yellow tint at the bottom (used the grey bars test from the imac section). If I book an appointment at my local apple store, will they take it in and replace the screen or give me a replacement imac? Any info would be appreciated thanks.
