Reset the camera using the instructions shown in the attached photo.
If the problem is not cleared by the reset, then, unfortunately what you have described indicates that there is a problem with the ccd (the light sensitive chip that produces the image) or the connection to it. If your camera was purchased less than a year ago and has not been dropped or physically damaged it is covered by Fujifilm's warranty and should be repaired by them using the information at the link below.
This has been a known problem with many digital cameras for years and while your camera is not on the list of cameras on the free repair program, the information at the link below does fully explain the problem and tells how companies handled it.
Please keep in mind that my diagnosis & solutions provided are directly dependent on the accuracy of your description of the problem. As with any "do it yourself" fixes, success is a "team effort", since I can't see or touch the camera, and relies on the customer's manual dexterity and ability to follow the instructions well.
