Hi @allang26275
I can't find the parts list for the camera but one option that you may wish to consider is to purchase a [https://www.ebay.com/sch/i.html?_from=R40&_nkw=FinePix+XP70&_sacat=0&_sop=15|faulty - parts only] same model camera as a donor (examples only) and use it for replacement parts.
Here's the ifixit [[Topic:Fujifilm FinePix XP70]] repair guide that may also help.
Just a thought.
