Recently my F401 has started to display images as bands of colour rather than full images.This is both on the display screen and in the final photo image. I have charged the Lithium NP-60 fully but still have the problem. Although now 5 years old I like this camera and am reluctant to scrap it. A new battery is £20 but before I buy is this the most likely cause of problem or the Smart Media card ? Any advice greatly appreciated.
