My screen collects thin vertical coloured lines from top to bottom across the screen. It seems they are picked up from the boldest color currently displayed at any time. They build / change / reduce according to whats on the screen at any time.
There is also some black lines running evenly across the screen spaced out by 10 or 15 pixels.
