Sorry to tell you this but your CCD is gone. In a fwe days time pics will be black in color. CP 5400 uses a batch of defective Sony CCD's. Nikon's service center in Kolkata, India replaced the CCD in my CP 5400 free of cost. This was because Nikon has issued a service advisory. Try your luck with the Nikon service center closest to your home!
