    I recieved this hand me down iMac from a friend. This is what the screen looks like. Is there anything i can do to fix this? are they dead pixels?? sometimes the lines change, sometime more appear, sometimes less. Horizontal and vertical lines are present.

    Looks like a GPU problem. It's not dead pixels.

    Definitely not dead pixels. Dead pixels are black dots on your screen. Stuck pixels are stuck on a specific color on your screen. As the above poster pointed out, this looks like a GPU problem.

    That's exactly what my iMac screen looked like when I took it into Apple for repair. Apple suspected a bad video card or bad motherboard during their initial analysis. Further diagnotics identified the video card as the culprit. Hopefully that's all that is wrong with yours.

    Good luck on this.

    After-thought:

    BTW, my system would freeze up too. Is your's doing that as well?

    Do you think there is something I can do here at home to fix the screen?

    It's not the screen that needs fixing. It's the GPU on the logic board. It's doubtful you can do anything to repair it. Take it to Apple.

    I agree with GGJstudios. Apple is your best bet.

    Just for reference, Apple quoted $392 as the repair estimate for the video card and $780 for the logic board on the work authorization. I had AppleCare so it did not cost me anything.

    That was back in Oct-2010.
