Canon EOS Rebel T6i Flash Assembly Replacement

Remove all visible exterior screws:

Two 6.84 mm J000 screws on the right side

Six 5.33 mm J000 screws on the bottom

Two 5.33 mm J000 screws on either side of the viewfinder

One 5.91 mm J000 screw on the top right.

One 3.39 mm J000 screw on the top left.

Locate the rubber grip on the left side of the camera. Using a metal spudger, pry the rubber grip off of the casing.

Remove the five silver screws underneath the grip.

One 5.83mm J000 silver screw

Four 5.85mm silver J000 screws

Using the same metal spudger as before, pry the rubber grip located just below the turndial. Again, be careful not to rip the rubber.

Carefully use the plastic opening tool to pry the casing apart along the seam.

Follow the seam with the plastic tool until the back is ready to remove.

To disconnect the white wire, pinch the wire casing and pull directly out from the camera. It will take a very small amount of elbow grease. However, do not force or pry it.

To disconnect the ribbon connector, softly pull the back away from the motherboard. It should come undone with little force.

Once removed, set the back in a safe place.

Remove the ribbon connectors along the bottom of the assembly.

To remove the Ribbon connectors that have a locking mechanism, identify the flap on the ribbon connector. Use either needle nose tweezers, or a plastic wedge to flip the small flap to the "up" position.

Once the flap is up, use the plastic spudger to pull the ribbon connector out of the connection using the hole in the center of the ribbon.

Remove the button cell battery from the motherboard.

Disconnect the small plastic connectors on the top left corner of the motherboard by gripping the small plastic portion of the wire and gently pulling out of the connector.

Disconnect all of the ribbon connectors along the top that you can get to. Don't worry about the connectors underneath or the ribbon connectors with the foam block, as these will be removed later.

Remove the four screws from the front of the camera. There are two screws above the lens mount and two screws inside the lens mount.

Remove the four screws left on the bottom.

Using the plastic wedge, pry the front of the casing off the camera.

Remove the yellow and red connections on the front near the black cylinder (capacitor).

The yellow connector will just pop out if pried from the bottom using a plastic wedge.

The red connector will pull out of the casing with either a plastic wedge or a thin set of tweezers.

Remove the diopter adjustment knob next to the viewfinder using your JIS #000 screwdriver. Once this screw is out, the entire flash assembly is ready to be removed.

Remove the entire upper flash assembly by gently pulling it up and off the camera. The flash assembly is sold as a single piece.
