I had the same problem and was about to scrap the replacement screen but first '''I tried disconnecting the battery connection again and holding the power button down for twenty second. When I reattached the battery and held down the power button it fired right up.''' Funny thing was that the old screen would work without the whole process of disconnecting the battery when I reconnected it in an effort to see if the new screen was faulty. This may just be something to do with the seven plus since this has never happened on other models.
