Hi,
one easy question first. Is the lens cap removed?

If your camera has built-in blinds to protect the lens, do they open?
Have you switched the camera to manual metering, or is your camera metering light badly? You could try resetting your camera (check your manual) to see if it helps. Maybe not enough light is coming through the lens and the image looks dar.
Otherwise, it sounds like it's a faulty sensor problem. This can happen, and there is usually little to be done. I would contact Kodak with this, to see if there's a solution. Some companies have decided to repair specific models free of charge because of faulty sensors.
