This guide shows you how to replace the shutter assembly in the camera. The shutter assembly is a fairly common component to need to be replaced as it has a limited life span and is a delicate part. Note that the cable which connects the shutter motor to the DC PCB board is soldered onto the board, therefore a tiny amount of soldering will be required for this repair.

Replacing the shutter assembly involves removing the image sensor from the camera, therefore extreme care will need to be taken while performing this repair. It is highly recommended that you use an anti-static wrist strap while working inside the camera to prevent electrostatic discharge. Since this repair also involves the image sensor being exposed for a period of time, it's also recommended that you work in a clean environment with minimal dust to avoid dust from getting onto the sensor while it's exposed.

Fortunately, the Canon EOS Rebel T3 utilizes washers to set the images sensor height (whereas some models uses springs). This means that the image sensor should be able to be reinstalled without the need for recalibration.

When you reinstall the main PCB board and are reconnecting the cables, note the single round black cable that leads to the top cover. This cable connects to the right side of the board and the connector is attached to the back of the board. To reconnect it, you simply need to push the cable down into the hole on the connector. This cable is a fiber optics cable used for the camera flash. Forgetting to reconnect this cable will likely cause the camera flash to no longer function.

The Phillips #000 screwdriver is marked as an optional tool as you can always use the JIS #000 screwdriver in its place (JIS screwdrivers won't damage Phillips head screws).
