My Canon 5D Mark ii back LCD screen just stopped working for the Menu screens, photo previews and live view. The only image seen on the screen is the "Sensor Cleaning" image when I turn off the camera. The body has 54,000 shutter actuations. Is there a known issue to cause this problem? I know the LCD is working to some extent due to the the sensor cleaning image being shown, but why nothing else is visible is boggling?
I have seen other posts where the back LCD only works in Auto Mode. This is not the case for my camera. Could a semi-stuck button being causing the problem? I don't see how a Menu/function modification could be the issue. I think I would have known what I did if this were the case. Would a reset to factory solve the issue?
