I dropped my A855 and the screen hit the floor directly and the screen went totally blank. Nothing cracks just minor scratches but the screen wouldn't turn on. I thought the LCD was damaged so I ordered a replacement but still there's nothing showing up after I replaced the LCD. Should I try replacing the Flex cable? Now I think that is not about my LCD, but was wondering whether would there be other components that was actually damaged and not the LCD or flex cable. Just wanna make sure before I spend another 30 bucks. Thanks!
