Problems with screen(flikering) bottom left loose

Have an issue with a Macbook Pro 15 Inch 2009, the bottom left part of the LCD screen has become lose from the lid. The Macbook works perfect if I dont move the lid, but once I move it or touch the screen on that area, I get a (1) inch vertical line, either solid or flickering, on the left side of the screen. I have attached a picture resembling what Im talking about, it is not quite as bad as this picture, but it is starting to look somewhat like that, very noticeable once the lip is close. I imagine I need to remove the LCD screen and maybe replace the LCD cable? any suggestions? Thanks in advance!!
