I have noticed lately that a couple of pixels on my EOS 5D II sensor are either "hot"or "stuck". Does any of you know how can I make my camera do a pixel mapping? Or is that something that can be done only at a Canon service facility? Thanks for your replies!
Generally if you put it into manual clean mode for about 5 minutes and then SHUT THE CAMERA OFF, they should clear. You may have to do it a couple of times but it generally works fine. As long as we are not talking about red pixels which appear in video's this solution is Ok. If your having a video issue the camera needs to go to Canon service for sensor work. People have been using this trick since the camera was announced with reasonable success.
