The answer is yes to both questions. The camera is behaving "normally" and I can see previously taken photos and the screen appears normal before taking a photo. I have also tried another memory card and it still does the same. I am backwards and forwards today but will keep checking emails. many thanks, Roger
It makes no difference I am afraid and I have also tried a spare battery I have and it is just the same.
Thanks for the prompt and easy to follow reply. I have tried a reset with no avail, so it looks like a new camera!! Thanks anyway, Roger
