    I have not seen any posts comparing these two symptoms together, but I am wonding if both exist on the same screens, or if they are infact seperate issues.

    I returned a 27" iMac i7 because it had both slight yellowing and terrible backlight bleeding. I have seen multiple machines first hand (3 Core 2 Duos week 41s) at different stores (Apple and Best Buy) that had no yellowing and no backlight bleeding.

    I won't get into how to check for yellowing, you can read about that issue here:

    But to check for backlight bleeding is both easy and impossible not to see if you have it. To check for backlight bleeding, a quick way is to bring up a site like or any other black background, and check for an inconsistent white glow on the edges of your screen. I had serious backlight bleeding in the lower corners of my screen, which happens to be where the yellowing was happening.

    I don't know if they are related, but hopefully we can determine if there is any correlation here.

    I did order a second machine, because I know Apple knows how to make a 27" iMac with a perfect screen (as advertised), since I have seen 3 of them in the wild. Hopefully they will be back to the quality that they had is their early production units very soon.

    Don't buy the new iMacs until this screen issue is resolved.

    The only way Apple will fix this is when it hurts their bottom line.

    I agree, but I need the iMac. Apple also gave me some good discounts, which I will lose if I return and buy at a later date. I will just keep returning them until I get a good one.

    The reason I started this thread up, is the backlight bleeding is easier to identify, and undeniable. If Apple or anyone else says there is no yellowing and cannot see it, they for sure will see the backlight bleeding if it exists.

    Fact: This PC user has never bought a Mac.
    He is here simply to cause discontent. Indeed, it's his only reason for signing on here as a "newbie" poster.
    He is one of several toying with the situation and is no doubt giggling whenever he senses anyone here agrees with him.
    All his other posts basically say "Don't buy Apple" and that's it. Don't take my word for it – just read his own words in his other posts.
