Assuming you didn't change the functionality of the button: the default function is 'focus hold', meaning that if you're in continuous AF mode, the focus is locked at whatever distance it was at and it'll no longer change with half-pressing the shutter button. Apparently this function doesn't work together with face/eye AF, which kind of makes sense: if you're trying to focus on an eye, the distance is usually not constant (either you or the subject moves). Locking the focus position will cause the eye to go out of focus.
As far as I know, the only way to reset this camera is through the menu, but of course, navigating in the menu without a display is not possible. One option could be to connect the camera to a TV screen with HDMI cable, press the show images button and see if you can access the menu from there.
Some users have reported an "unofficial" way to perform a hard reset.
Please note that I have not tested them and I am not aware if they work or ultimately you will end "bricking" the camera, so this is a big "proceed at your own risk", assuming that you have nothing to lose and everything else failed.
Remove the card, so your pictures are safe.
Try several times removing the battery with the camera on and leaving it out for some time.
The sudden loss of power might cause the camera to reset.
Hello. While traveling in India, my camera on a tripod got caught in the wind and fell from above. Unfortunately, I managed to find it Unfortunately, viewfinder didn't work. So I made a mistake and switched the settings to ONLY viewfinder. And now the LCD screen shows nothing and I can take photos blindly. I tried changing the settings using the chain navigation buttons. But no luck. Could someone with this camera please Write instructions on what buttons to use to get to this option?
MENU;9x RIGHT; 3x RIGHT; 1xDOWN; SELECT/CENTER; 1xUP; SELECT/CENTER
Can someone check if this works for them with a LCD screen on?
