Zoom disp set mode dont work - Casio EXILIM ZOOM EX-Z850 Digital Camera

This took me a bit, in fact I needed to got to one of my Fujifilm cameras to see if I could duplicate what I was thinking the problem could be. So here goes. There is a small button on the back body just off the lower right side of the LCD screen it has Disp/Back written on it. What I'm saying is that this button has been pushed to give a blank screen which will affect both the viewfinder and the LCD. To get to that point I had the camera in Manual mode ISO at 100 and the lens cap on. The aperture was set for F9 and the shutter at 1/60th. My camera has a "shake" icon so in Auto and program there was the shake icon on the LCD screen it also showed in the "A" mode as well. Now that said my version of your camera may be a few models ahead, your camera may not have the camera shake feature or icon. In short I think you have pressed the "Disp/Back" button and changed the view mode.

should be set before taking photos or videos.

enter the camera's settings menu.

Go into the vehicle settings with the radio controls. With the key turned to ACC, hold DISP on the radio for about 6 seconds and it should go into settings mode. Press DISP until you see oil life in all caps, then use Prev. & Next to scroll to reset oil life mon., then push DISP again. you should here a beep and the display should read Done. Scroll to Exit and press DISP again. Good luck

Think that you might have accidentally pressed the DISP or DISPLAY button on the back of your camera. This manually turns the LCD display on and off to save batteries. You would then use the optical viewfinder in its place. To turn the screen back on, just press the DISP button one more time.

CHEVY IMPALA &
MONTE CARLO
On a Chevy Impala or Monte Carlo with indirect TPMS, a totally different reset procedure is required. You can use the light switch or radio to reset the system. With the light switch procedure, turn the ignition on (engine off), the turn the light switch from OFF to parking lamps three times within five seconds. With the radio technique, turn the ignition on (engine off). With the radio off, hold the DISP button until “SETTINGS” is displayed. Use the SEEK button to scroll down the menu until you see “TIRE MON.” Press the PREV or NEXT buttons until “RESET” is displayed. Then press the DISP button again. You should hear a chime and see “DONE” to indicate the TPMS system has been successfully reset. Use the SEEK button to scroll through the menu until “DONE” is shown, then press DISP once more to exit from the learn mode.

This should reset whole camera to factory setting.

I too have the exact same problem, and an online search turns up others with similar Casio Exilim models, with the same problem. It involves a malfunctioning Disp, Zoom, and non-functioning Set button, with all other functions working OK. Casio Support seems to recognize the problem, and indicates it has to be fixed at one of their authorized repair centers. Start with their online system: https://www.ecasiorepair.com/
