It would be best to post the file so that people can explore/experiment before offering advice.
That being said, I can suggest the following if all the hinges are identical.
1. Take one hinge and alter its Reference Point to a place that makes it convenient to snap into position in your drawing.
2. Select the hinge, move it to Layer 0 and use the Format | Block function to make a library part.
3. Pull out this block item to place as needed.
4. If the visibility problem re-occurs, go to Wireframe mode (or to Hidden Line and back to Wireframe if already in Wireframe mode) and change the view (World, Front, whatever) to see if visibility is restored.
