How to fix a dead pixel on Canon 80D (and others)

You shoot a video, take some photos, and you see a tiny white, blue, or orange spot in the video and on your photos… the horror!! But don’t fear, there’s a way to “fix” this without sending your light capturing baby back to Canon for a couple weeks or longer.

If you’ve got a dead, or hot, pixel there’s a way to remap the sensor. Are you physically repairing the sensor? Not exactly, but you are telling the camera to work around it. The catch, you’ll need to do this each time you update your firmware. Fortunately it’s really easy.  Here’s how.

First, confirm you have at least 50% of your battery capacity available.

Next remove your lens and put the body cap on.

Now you need to do a manual sensor clean. During the manual sensor cleaning process there is some Canon wizardry, yes, wizardry that will remap the sensor and remove the dead pixels from your video and images.

Navigate to the “Sensor cleaning” option.

Hold your camera face down. Now select “Clean manually”.

Continue to hold the camera facing down for 30 to 60 seconds in manual clean. Power the camera off. Your sensor should now be remapped and the hot pixels no longer visible. (Remember you will need to repeat the process when you update your firmware.)

If you still see your hot (aka dead) pixels repeat the process again, but heat your sensor up first by using live view or shooting video for several minutes. Do the process immediately following heating up your sensor.

I can confirm this worked for my camera. I cannot confirm this works for other cameras, and other brands of cameras, but I have seen forum posts stating it works on other models and makes.
