The machine is still under warranty from samsung so I would call 1-800-samsung to find the nearest service center. Problem could be caused by a bad main board, bad lvds cable or a defective t/con board or lcd panel.

Had this exact problem diagnosed by a local repair shop as a bad LCD panel. According to the technician there's a loose ribbon cable on the panel and it would cost as much to replace/repair as a new TV.
