I have a thin vertical blue line on the screen of my iMac that won't go away. Any fixes?

Make an appointment at your local Apple Store or Apple Authorized Service Provider and let them have a look.

Take a screen shot & view that in Preview, move the Preview window around, if you see double lines it's a Video card/VRAM problem, if the lines do not move moving the pic around then it's the LCD or cable.
Thank you. It doesn't appear in the screenshot.
Then it's the screen, den.thed has the advice on that.
