Pink line on screen

Hello everybody. Well I dropped my phone now I have pink line on the screen. This is the second time this has happened. Does anyone know what causes this? I bel8eve it has something to do with a sodier connection. It is a manufacturer defect. However s8nce it is the international version and I live in the US no Samsung Warranty. What I am unsure of is how to fix it? Is it the LCD screen, digitizer or something else. Thanks
