Answer to: Display issuesClean your connections with rubbing alcohol, especially #1. I had the same problem for months. Then while repairing another iphone took mine apart to deduce what was wrong with hers. Well it's still black screen but I did clean my connections and now it works great. The other phone I haven't figured out. It's completely black screened. As if the brightness were all they way down. I think it may be a shot LCD. Mine works thou. YAY. I really would rather hers working.
