Discovered purple/blue vertical lines going down my laptop. At the very top the lines are very dark... as the line down down the line gets fainter and looks invisible but in some random spots there is some dark spots. Its probably about 10 pixels wide. The first time I turned it on it was a solid blue line all the way down but now it is blue and purple for the most part and varies in visibility through the day. Not sure if this is a video card issue or the LCD monitor. Any comments to fix or what is wrong is appreciated. Thanks!
