    Take a look - a picture can explain more than 1000 words. The TVish vertical lines are just the camera, but anything going horizontally isn't :(

    This machine is out of warranty.

    Anyone have any suggestions?

    Is it just me? I don't see anything.

    Can you explain?

    maybe bad CRT, or PAV board.

    Not something you can fix yourself, however. Be about $200+ to repair

    look at the horizontals streaks...

    and it's a Flat panel iMac - not a CRT

    And does this still happen at a different Resolutions and/or Refresh rates?

    Have you tried turning down your contrast? (Do LCDs still have such a thing?)

    it happens at all resolutions and refresh rates, and in everything (OS installers, OS9, OSX)

    turning the brightness/contrast down does nothing... everything just gets darker

    the problem seems to be only getting worse :(

    see the picture below

    the background of the webpage is meant to be solid black

    The first picture sure makes the screen looked curved like a CRT. I was thinking the same thing. I could see this happening on a CRT, but on an LCD, it's probably the video cable or, hate to say it, the motherboard.

    plugged in an external monitor and it's fine - so it's either the connection from the video chipset to the LCD or the LCD it's self.

    Problem is how would I fix this?

    I can't afford to pay for a repair - i was going to sell this machine, but obviously I can't sell it in the state it's in.

    Does anyone have some instructions on how to open this thing up?

    an LCD is one part that i really always recommend people not try to fix. there's not a lot that you can do, except for damage it past repair... i'm afraid i can't tell you how much it will be, it depends entirely on what part is broken and where you go. i wish you luck tho--
