Crisscrossing vertical color lines, also swirls on laptop monitor

I'm helping a friend with her laptop - trying to get some documents off before sending off to Dell (this is a Dell Studio book).  When her computer boots up there are thin color lines running veriticall over 95% of her monitor as well as black horizontal lines running across 30% of the screen.  There are a three  major lines in black that are curve around and through the vertical and horizontal lines.  The computer will boot up to Vista but I can only see 5% of the left hand side of the screen - and not enough to see enough directories or to drag files to a flash drive nor enough room to see cmd prompt to copy any files to a flash drive.  The thing is that when we turn off the monitor, I can still see a ghost image of many vetical lines and the swirl lines.  Could a problem with a video card permently etch  in both vertical and/or swirl lines? What could this be? I've tried an external monitor but it's not seeing this.... Thanks.

Sounds like a faulty screen. You'll need to use an external monitor to save your fridnd's stuff. Try hooking up the external monitor before you power-u the laptop.. Also, some computers don't detect an external monitor automatially and you have to press some combination of keys to select - like Fn + a key.. Look in the computer's documentation (if any not on the computer) or google it...

Got stuff off her computer, fine - no problems when cooked to another computer so not video card, must be faulty screen.

She returned to Dell and it turns out that she had moisture in the screen (this would explain the "ghost lines" when the monitor was turned off.  They charged her something like $300 to replace.
