Cupboard fold-out desk (Ibrox G51)

Medium-brown wood, signs of wear and could use some repairs. The hinges on the tabletop have come off on one end and part of the back is loose.
I have been using the desk as is by pulling out the drawer and resting the tabletop on there, so it is not strictly necessary to repair the hinges.
