Re: T4i Dead/Hot Image Sensor Pixel

You can try to map out the stuck pixel. But from what I've heard it only work with still image because pixel mapping is not active during video recording. Anyway, it's worth a try.
"Fix for dead Pixels : Set camera to perform sensor cleaning mode manually (not auto) for one minute. You only execute the function, not exactly performing the whole sensor cleaning procedure. Magically, the sensor cleaning task should shake the stuck pixels off, if not, repeat couple more times until it does. Otherwise, time to call the technical support."

Re: T4i Dead/Hot Image Sensor Pixel

I did try that last night I actually executed it a couple times and it made no difference. I spoke to a support tech and depending on how bad it is they have the ability to use software to exclude the bad pixel or they may elect to replace the Image sensor entirely. My hope is that they will do the latter.
