First thing I would do is a Hard Reset: Press and Hold both at the same time Top/Power Button and Home Button for about 20 seconds, keep holding and if it works the normal White Apple will show and it is fixed.

If not, then you may need to carefully open the iPhone up again and carefully seat (LCD) Cable #1 connector by pressing it to the Logic Board.

Before doing any of this make sure iPhone is OFF. To be certain iPhone is OFF move vibrate/mute switch, making sure it does not vibrate. Do not mess with the Cable #1 if the iPhone is possibly powered on.

Good luck,
