Hey cab...this was taken right from the Canon site. It's a bit long but happy reading and I hope this helps.
This Service Notice will update Canon U.S.A., Inc.'s previous CCD Image Sensor Advisory, dated October 6, 2005.
It has come to our attention that the vendor-supplied CCD image sensor used in certain Canon digital cameras and digital video camcorders may cause the following malfunction: When the product is used in recording or playback mode, the LCD screen and/or electronic viewfinder may exhibit either a distorted image or no image at all. While reports of this malfunction have been rare in the United States, we have determined that it may occur if the product is exposed to hot and humid environments.
Notice of Additional Affected Products:
As a result of our continuing investigation of this malfunction, we have determined that the 11 models listed below, in addition to the 16 models listed in our Service Notice concerning this malfunction, dated October 6, 2005, may be affected.

It has been confirmed that the connecting parts of the internal wiring of the CCD used in affected products may become disconnected, especially if the affected products are stored or used in high-temperature and high-humidity environments. If this occurs, the signal is not output from the CCD normally in Shooting Mode, which may cause a distorted image or the absence of an image. This malfunction can be confirmed on the LCD monitor screen during shooting. The same malfunction also appears on the recorded image.
Effective immediately, and regardless of warranty status, Canon will repair, free of charge, the products listed above exhibiting the above-mentioned malfunction if Canon determines that the malfunction is caused by the CCD image sensor. Canon will also cover the cost of shipping and handling in connection with this repair.
