if the lines are permanent when the phone is powered on, the LCD is probably defective. If it happens on any screen (booting screen, home screen, settings screen, app screen) while the phone is on, you are describing a bad LCD. You may try re-seating the LCD cable to the connector but most probably the LCD is bad.
