Hi, I got an iPhone that was accidentally dropped. Since then, the screen is white with some vertical semi invisible lines. I know the touch works as it makes the "Slide to open" sound and I'm able to turn it off. 1. I made soft reset and restore via iTunes, no avail. 2. I opened the iPhone, checked the flat cable and 2 connectors, once reconnected goes back to same white screen. 1. How can I make sure that I properly reconnected the flat cable? 2. Is there anything else that I can do to repair it? 3. If I must replace the screen, which screen do I need to purchase off eBay? There's no Apple service in my country, so I must DIY myself Thanks!
