After I bought my new Canon EOS 40D and took some blue hour and night photos I found out that i have a bright white pixel near the center of the image. I found out that the

RAW converter fixes this problem but JPG files are still an issue.

This pixel is a stuck pixel, or sometimes it called dead pixel. Usually stuck pixel is bright, while dead pixel is black.

Of course I was not happy because i thought this means I have to send my brand new camera back for a replacement or repair. So I started to google this problem and deep in a forum I found something, something interesting: It seems Canon cameras has a self repair function that can be activated through the menu. All we have to do is to charge up the batteries and go to the menu and initiate a “Manual Sensor Cleaning” then wait about a half minute then turn off the camera.

I made several tests and was not able to see the stuck pixel again on JPG images after this process so IT WORKS!

UPDATE: It seems this method works on some Nikon models too.

After I posted this solution to my blog I get several responses so this method works on
