Green Blob and Fading to White

I have an HP dv6000. It is relatively new, about 5 months old. I have been having a problem with the LCD screen lately. I will be using the laptop, just perfectly fine, and all of a sudden the screen will become all jubbled, and horizontal lines will shoot across the sceen. It is impossible to use when the screen goes like this. Under these conditions, if it goes back to the log in home page where it's suppose to be a sky blue color, the screen displays big green blobs. With these blobs, if you are unactive on the laptop the screen will then fade to a white color before the screen savor turns on. Can you help me at all? Thanks alot, Dave.
