It is most likely the Display Assembly, but there are no guarantees. If the lines are too annoying, then connect the laptop to an external display. This laptop is not easy to work on and can very easily be damaged even if a person is an experienced hardware tech. In some regions it may be possible to mail the laptop directly to Apple for repair. Click the "Contact Support" link at the top right of this page to see if a mail-in repair is an option in your region.
