If the flash of your Canon Rebel T6i (also known as model EOS 750D) is malfunctioning — not producing any light or not triggering when taking a picture — use this guide to remove and replace the entire flash assembly.
Make sure to check the flash settings on your camera and confirm that the flash assembly is faulty. The camera flash should trigger when the camera mode is set to Automatic (A+) and the scene you are photographing is very dark.
Before beginning, remove the battery from your camera and disconnect from from any external power source.
