NAV has white line marks appearring
 

I first notice a white line coming down the center of my NAV system and thought it was a scratch. But then more lines started to show up and I know it could not be scratches. It seems like when it gets really cold these white lines which looks like it's coming from the inside of the screen. I dont know what is causing this. it's not even a year yet and screen is messing up. Does anyone else have this issue. I haven't gone to the service center yet to see what the hell is going on with the screen.
