Hi - Same problem here after less than 4 shots.
If it's less than a year old, send it in for warranty. You will need the receipt (just printed it from, amazon), and they will direct here: [link|https://camerarepair.fujifilmusa.com/Forms/RepairForm.htm|FUJIFILM Repair Form (fujifilmusa.com)|new_window=true]. Send that with the camera to the address on the repair form.
