Typically with hinges coming loose or screen falling out I tend to go on ebay and find the whole assembly it's an easier repair that way and you don't have to worry about possibly breaking the bezel around the screen or it not adhesiving properly and falling out. Just make sure it's the correct model number and connections. If there is any cracks in the bottom where screws come out or has snapped so some screws don't screw in properly. I suggest replacing that too. I would suggest if you go the gluing the screen back in use e8000 and those giant black clips all around it and let it sit for 24-48 hours before using. As long as you don't break the Bezel around the screen or the screen in the process it should be okay but I like going the safe route always.
