I have had a Cannon T3i for two years. Wonderful camera and no problems. I was without my camera for 26 days. When I finally got it back in my hands, turned it on and flipped open the screen I see a very basic summery of my settings. I do not see my "live view" screen as you would. I've tried everything to correct it but failed. Has anyone else experienced the same problem? Any advice that anyone can give?
