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

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--
