Hi,
Here is a link to the [https://content.etilize.com/User-Manual/1032801992.pdf|service manual] for your laptop.
Scroll to p.89 to view the necessary pre-requisite steps and then the procedure to remove / replace the display hinges.
Here is a link to just one [https://www.parts-people.com/index.php?action=category&id=141&subid=487&refine=hinge|supplier] of the replacement part. It is not a recommendation to use them. It is merely shown to give an idea of the cost of the part. There are other suppliers online that may suit you better. Just search for ''Dell Inspiron 3541 hinge parts'' to get results.
Hopefully this is of some help
