Recently I get these black lines on the screen whenever the screen is black/blank. When gameplay or colour is on the screen you can't really see the lines and they just happened recently.
I'm using the new xbox 360 slim 250gb and a hdmi cable. I checked the cable and it's all fitted perfectly in. I was playing Assassins creed brotherhood and then suddenly the black lines appeared halfway through. Whenever the screen is loading and it's a black screen I can see the lines.
Does anyone know what's wrong? I just bought this xbox 360 1 month ago.
