Rearview camera display with lines

Any reason why the rearview camera display would have lines running through it, almost like what you see when you photograph a television set?

I picked mine up this monday, RVC works great NO lines at all, try cleaning the lense.
Mine comes on almost straight away from start-up too. You can select it anytime on the move at any speeds.
