A flashing F-- almost always means that the camera cannot see the lens.
- make sure the lens is set to the 'A' position if it has an aperture ring. Newer lenses might not have this.
- take off the lens and gently buff the contacts on both lens and camera with a microfiber cloth
- check the contacts to see if they are all present and protruding properly
- try a different lens if you have one

Post back with the lens model, that might help if it is not a modern Pentax lens

Is your lens attached?
Are you using an older lens?
