Most likely the built-in Display Assembly is bad and needs to be replaced. You can confirm the diagnosis by connecting an external display and enable mirroring. If the external display does not show the vertical bar, then you know that the built-in display needs to be replaced. Have Apple or an Apple Authorized Service Provider examine the laptop to provide you with a repair estimate.
