    Just set up new iMac and when I turned down the brightness in system prefrences the thing starts buzzing. Its not very loud and I'm pretty sure it goes away but doesnt really seem normal as my old 24" never showed any signs of this. Anyone else?

    Yes, lot's of other people have this problem.. Mine does it from 50% brightness all the way to 100%. Under 50% i don't hear it. I'm returning it; also because of the yellow tinge + seagate rumble.

    Yes mine is the new unit that just came out. Do you think this screen buzz warrents a return? On one hand it's not the biggest problem in the world but on the other hand it is a brand new unit which should be problem free. What to do?

    Call Apple if you want to have it replaced. I would figure that the buzzing is enough for a replacement.

    How's the screen otherwise? Yellowing, backlight bleed?

    Screen seems to fine. there is a little bleeding in the bottom corner, but very minor.
