I looked into to this it is the ccd and Canon will fix it for free (shipping included), as stated below. I have copied what has helped me!
It has recently come to our attention that the vendor-supplied CCD image sensor used in this Canon digital camera 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.
Effective immediately, and regardless of warranty status, Canon will repair, free of charge, products exhibiting the above-mentioned malfunction if the malfunction is caused by the CCD image sensor. Canon will also cover the cost of shipping and handling in connection with this repair.
U.S. residents are kindly directed to contact the Canon Customer Support Center for further assistance at 1-800-828-4040. Support hours are Monday thru Friday - 8:00 AM to 12:00 midnight; and Saturday 10:00 AM to 8:00 PM (all times EST).
