Step 21

Remove the single 11 mm Phillips #000 screw securing the dioptric adjustment knob.
When replacing, make sure you do not tighten the screw too much, as the knob will be locked in position if you do.
Before replacing the knob/screw, make sure the grey plastic mount (screw hole area) is aligned with the outer case. If it is not, it means the lens and the knob are not lined up. With a flat screw driver, give the grey plastic a few rotations, and it should fall in place, and realign properly.

Step 23

Lift the top casing up and away from the camera.
I’m not sure what this is for, but make sure the black plastic bit (not a cable) goes into the white plastic bit, as shown on the picture.
Here is a view of the black plastic bit. It is on the underside of the top cover.

Thanks for this guide, it was helpful. I edited it to add some details, I hope they help the next person.

My camera is also this model, but I found that there were some differences, and I’m wondering it I got a refurbished device for the price of a new one… For instance the top cable were soldered to the front of the camera, no plug in sight. I found more than 1 screw that had a different thread to the others.

All in all I managed to fix my issue which was with the viewfinder. The 550D guide for the viewfinder will work for this camera (I just used it and the viewfinder parts are exactly the same) Canon EOS Rebel T2i Eyepiece Replacement

For me some bolt sizes were also different, i just labeled every bolt location with a piece of tape with a number written on it, and kept track of the bolts.

This briliant. I don’t dare to unscrew my camera yet but if I do this will certainly help. I did do the back cover already but the top cover is serious business. Thanks a lot for the many photo’s provided.

Excelent step-by-step! I managed to fix my camera’s flash mechanism without buying any part.

By the way, that small plastic that looks a cable but it’s not a cable is an optic fiber, that carries a small amount of the flash light to a sensor on the board.

A lens in the eyepiece of my 600D was popped out. I used this guide and this one: Canon EOS Rebel T2i Eyepiece Replacement to fix it. Thanks!
