I menu Advanced\Miscellaneous, is 'Disable LCD off' set to 'No' ?
It was set to Alt. I have changed it to No as you had said. And now, after camera goes into power saving mode, the only one way to wake it up is ... rotating it!
or press shutter button, which also makes photo then. Any other button doesn't work. When SDM is unloaded, you can wake camera pressing any button.
Something strange does, when USB remote is plugged in, and camera goes into power saving mode. When I press the remote button, the camera wakes up and the focusing is done. After pressing and releasing it again, the photo is taken. After that, the display starts to blink. Not whole display, but SDM header only. All other display element, such as WB setting, aperture and shutter values etc, are disappearing. Im confused whats going on
