    Hi...

    So I turned on the iMac and it was running fine for about 5-10min when I noticed total loss of color to what looked like 24 colors and flickering... I tried to do the display firmware update 1.0 (I'm running MAC OS X 10.6.2) it gave me some alert that I don't need this update... All software is up to do...

    Any ideas?

    Attached a couple pics...

    Tks,

    Sounds like the GPU! I would call apple on this issue asap.

    Definitely the GPU here. Sucks, but it happens once in a while. Another firmware update is unlikely to fix it.
