Our 4-5 year old Canon PowerShot S400 (Digital Elph) started acting strangely. In capture mode the LCD is all black or looks like it is on acid. Taking a photo captures the weirdness (see the image below), usually very distored and purple-ish. The LCD works fine, so you can still review photos and use the menus. I did a bit of searching and found that the problem is most likely a known issue. I called Canon and they are sending a prepaid label so I can ship the camera to them to evaluate it. If it is the known issue, they will fix the camera and send it back to me free. I would expect this if the camera was 90 days to 1 year old, but I am very pleasantly surprised since it is 4-5 years old. Here is a link to Canon's Service Notice.
Update (09.30.2009)
I got the UPS label from Canon and sent them our S400. I received an email from them today stating:
Based on our initial examination, we will start the necessary repairs at no charge to you. You can expect the repair to be completed and returned back to you within approximately 7 business days.
Update (10.05.2009)
I got email from Canon on Saturday with a FedEx tracking number. They have fixed and shipped the S400. FedEx tracking says it should arrive tomorrow.
Update (10.07.2009)
FedEx tried to deliver the camera yesterday, but it required a signature, so they did not leave it. I signed the slip they left and they delivered it today. It appears to working great, and not only did Canon fix the issue with the CCD, they replaced the two housing parts that had dents in them. Thanks Canon!
