A cabinet door needs removing, repairing, and refitting.
I think the door/hinges have previously been pulled off. Where the hinges screw to the inside of the cabinet is damaged and as such, the screws can't bite properly and aren't holding the weight of the door. Everything is wobbly and wonky, it's already fallen off once.
I would think either the hinges can be moved, or the areas inside the cabinet can be made good, and it can be re-attached in the same place.
They are standard cupboard hinges; pictures are attached. The cupboard is in the kitchen, under the sink. The material is MDF or similar (not hardwood). You'll need your own tools.
If you need any more pictures etc. please ak.
