It may be that your connections are not down right or that you have got dust or dirt in them. Try reseating your connectors and checking for any thing in them. alot of the time part of the gasket fall in them. If you check all those it could be a bad screen. Also make sure your battery is disconected first before removing any connectors or reconnecting them. Always try your screen before completly closing the phone back up to see if there is any problems.
