im in dub 12 dave if you want to come up and sort it for me lol

 

Look at your display settings. The reason why you would have the "background" and no icons is because you have it set up to extend the main(laptop) display(you use your TV as a dual monitor). You need to mirror the TV or have it set as primary display.
