    Just got a refurbished 27" Imac I5 with the Radeon 4850 yesterday.

    This happened twice yesterday, so today, when I powered on I had my blackberry ready to record.

    As you can see theres a large green band (yesterday it was accompanied with a red one) that spans the vertical aspect of the screen. The bars disappear after 30-1min.

    I've tried searching and haven't found anyone with a similar problem.

    Any help or suggestions is appreciated!

    I had the same issue, it's a hardware problem. You need to return it.
