I think I've narrowed it down to wrong equipment.....the model #'s are the same as the 4S, not the iPhone 4

If you have checked all your connections and it still doesn't work then you may have trapped the LCD flex cable and bent it whilst installing the front panel, this would result in a black screen. You would need to buy a new one.
