Black Vertical Lines On Macbook Pro Display
I bought a new 15.4 inch Macbook Pro about a month and a half ago and started seeing black vertical columns displaying statically on my display. Here's a link to the picture of it I took with my cellphone

So here I am about 1 month later with the new laptop and it's starting to happen all over again. I can usually get the screen to go back to normal after rebooting and it will be fine for a few days and then it starts all over again.
Any ideas of what could be going wrong and any advice on what I should expect apple to do about it would be highly appreciated. I really don't want to have them replace a second time only for this to happen again.
Thanks
