Nikon Corp. has notified users of its "COOLPIX 5400," "5000," "4500" and "3500" that a malfunction has been discovered in these models. Some units of these models have turned out to rarely render abnormal colors and display no images or distorted images.
Ahead of this, Nikon also reported a similar defect found in three other models in October 2005. Like this preceding case, the latest defect is also attributed to CCD soldering degradation caused by aging. The controversial CCD was supplied by the same manufacturer of the CCD used in the defected models announced before. The company said it discovered the CCD malfunction after receiving increased reports of a malfunction concerning the abovementioned four models from their users living in a particular area (hot and humid environment) in and after the summer 2006 and voluntarily testing them.
Nikon stated it provides free CCD replacement if abnormal color rendering and such phenomenon occur with its camera and the company find a malfunction in the camera's CCD, regardless of expiration of specified warranty period.
