Hi Kimmy_a72,
The camera can show a few different displays and one of them is a blank screen. If the camera got switched to that screen it would act similar to what you are describing. You can check that by turning on the camera and repeatedly press the Info button. Each time you press the Info button the camera will cycle to the next display type it can show. When you see the one you prefer stop pressing the button and the camera will remember the screen you left it on. When the camera is set to the blank display it will not playback photos, but when it is set to one of the displays that shows information your photos should be played back after you take them.
If the LCD is going blank without pressing a button that is a sign the LCD is malfunctioning. The Info button is the only one that can make the rear LCD blank. In that case we would recommend sending the camera in for repair.
Canon U.S.A., Inc. has created a new online repair portal that allows you to set up service in a few simple steps. The repair portal gives you the ability to set up service for multiple pieces of equipment at once, and to receive a repair estimate in the majority of cases, depending on your model and issue. The portal also allows you to upload images or videos that will assist us in repairing your product. You can also select how you wish to be notified of the progress of your repair. The portal's service history section allows you to view all services that have been performed on any of your camera or video products since January 7, 2020.
