Hello -
I have been using my EOS 77D mostly for sports for the last three years. The camera began to stop functioning while taking pictures. I have read about cleaning the contacts on both body and lens and keeping a fully charged battery but that does not resolve the problem permanently. During a shooting session, I have to remove the battery and re-insert it. That usually helps, for a short while. Also, when I remove the battery without turning the camera off first, the LCD screen still stays lit. I have only gotten two error messages in the three years and I do not remember the error code. I recall it being something related to "not reading the lens".
Does anyone have suggestions as to what is causing this issue and how to resolve it?
