Anyone know what to do. It happened two weeks ago, and all I did was restart the car, and eventually it came back. I started the car today since then and it has gone again, and restarting made no difference yet.

I don't understand why the line came back by restarting the car, and what the problem is. What type of display is it? LCD, if so I thought that once it goes it never comes back?

Appreciate any help.
