Canon EOS Rebel T6i PCB Flashboard Replacement

Remove all visible exterior screws:

Two 6.84 mm J000 screws on the right side

Six 5.33 mm J000 screws

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 seem 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.

Now to remove all of the bottom ribbon connectors.

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.

Go ahead and 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.

Now that you have removed the flash assembly, it is time to remove the motherboard.

First, the three remaining ribbon connectors should be gently disconnected. They are both located on the upper right side of the motherboard.

Remove the two screws connecting the metal port connector to the motherboard. After the screws are removed, slide the metal piece out of place.

With all the connectors and screws removed, Remove the motherboard form the device.

Warning - Failure to follow steps may lead in damage or injury from electrical shock. Before removing or touching the PCB board, the Capacitor needs to be checked for voltage. This device is the black cylinder on the camera. Place a voltmeter in parallel with the capacitor. If a charge is detected, make sure battery is removed from the device.

Furthermore, The positive pin is connected to the positive terminal and negative to the negative terminal. Then switch the setting of the multi meter to ADC for direct current amperage. .

The meter will fluctuate with a current until reaching zero. This process will discharge any residual charge.

Warning - Failure to discharge the capacitor may lead to electrical discharge and shock. The meter must reach zero to prevent any further damage to the camera.

Caution - Using a magnetic tipped screw driver may cause damage to the board. ordinary bits are preferred. There are 3 screws that must be removed in order to disconnect the board.

Furthermore, there are several ribbon connectors that need to be removed. Marked in red.

Remove the four wire connectors on the front.

Remove the two wire connectors on the back.
