Screen on powerbook covered in turquoise lines!?

My powerbook has suddenly developed a turquoise hue across the whole screen. They are actually small rectangles and columns. It cropped up randomly. I turned off the computer and left it off for a good few hours and its still there. They kind of come and go on different parts of the screen now. Its just making everything have a turquoise tint.

Any help would be much appreciated!

Sounds like to me it could be a problem with the cableing in the hindge...

Go to a repair shop which supports apple, they will give you a price for a repair. In many cases it is better of to just buy a new mac, as the price for a new one can be as much as a second hand one on ebay...

If you can't afford that i would suggest going on ebay and looking for spares and repairs powerbook and see if you can get it cheap and fix it urself...

Goodluck

It seems it might be as suddenly now the turquoise lines have gone. I am worried they will return though. We shall wait and see. I thought it might be the videocard originally but if it was could it return to normal so simply?
