Hi. I have never had to tighten hinges before and i am not 100%. However if you remove the front bezel you will clearly see the hinges. Get a pin and pick out the rubbers that run around the bezel, undo the screws then very gently you can pick off the bezel working your way around...Go carefully I had one snap before. That will give you access to the hinges.
good Luck
