Its possible that you caused a non-fatal short when plugging in the new screen. I have seen a short prevent the display from functioning even when replugged, and the device power cycled. The 2 ways I've seen devices restored to full functionality was a soft reset or a full cycling of the battery itself (drained to zero then charged until boot). Of course this only applies if you (one of the following) left the phone on/the battery plugged in/were not properly grounded when performing the repair.
