I found when I was doing a video that one of my camera’s had several hot pixels. So I set out to find out if they could be fixed. Surprising even me there is a possible fix for this. It is a simple one minute procedure that you can try and see if it works on your camera.
If it works you solve a problem at no cost and if it doesn’t work you are not out anything!
This procedure does not involve doing anything with your camera that it is not designed to do by the manufacturer. NEVER do anything to your camera that your are not sure the manufacturer has designed it for. Even with this being a simple procedure do so at your own risk.
