How do you get the camera back to the original settings

Your camera works just like a film camera SLR,. You use the eyepiece to frame and focus your picture. The LCD screen is for reviewing pictures taken or menu operations. You cannot preview a shot on screen before it is taken with the camera.

just send it to a repair centre, they will repair for free. the problem could be the mainboard, and needs to be changed
