Question about Canon EOS 400D / Rebel XTi Digital Camera
I had the same problem with my 400D. It refused to focus. On manual focus I could take pictures though, but not on Auto focus.
What happened was I cleaned the mirror with a piece of soft cloth, the spring hooked onto the cloth and came loose.
I took my lens off, checked the mirror, found that the little spring connecting the mirror and the little glass part above the mirror was loose. Took a lot of patience and hours to get it back in. I used a pair of tweezers 2 x toothpicks and a short piece of fishing line (thin line). Go have a look at another 400D how the spring should be clipped in. I used the fishing line to hook the " L " shape of the spring back in after I lined the back part of spring up, since there is no space next to the mirror and the body of the camera.
Like I said. This takes a lot of patience and be prepared to sit for 3 to 4 hours.
It worked though.
Hope this helps.
Where can I get a service manual for the 400D ?
