Digital Troubleshooting Sensors & CCDs
This is an example image from a bad CCD. This can happen in both point & shoot digital cameras and digital SLRs. This is especially a common issue in many of the older p&s. This is an extreme case of bad CCD, but they sometimes go out gradually and you may have your actual taken image with some minor lines or discoloration through it. This is not an easy problem to fix, and is not an issue for home repair. If you have this problem, you will need to send that camera out to a repair shop, or in some cases may be under warranty through the distributor.
