Just received my R3 back after the sensor has been changed, done by official Canon site. When I switch the R3 on I can make a photo, however I cannot see what I shot. Not one button reacted, even the menu button does not show anything. Connected to the PC via the USB-C the camera is not visible on the Mac. When I with the R3 off, the small screen shows data which I have not seen before, see the photo. I hoped there would be a HARD reset, who can help me.
