Check for recall notices in the US, Canada and Europe. Mine went through the same thing. Repair shop told me the CCD was dead, but neglected to informm about the recall readily available. Found out about it through a friend, sent off the camera, and have it back from Nikon now with new CCD for free (and they fixed the faulty flash as well). Form for recall in Canada is available at http://nikon.ca/advisory/5700_en.asp .
The CCD - Imaging IC is faulty. e mail me after confirmation for spares. sonyspares
