Please don't be insulted (because I don't know you) if I ask if you have repeatedly pressed the DISP button to cycle through the display options?
Nothing else will display if there is no card in the camera - as is indicated.
I just tried that and nothing happened. None of the cameras settings display anything besides the video setting.
That’s not Live View or Video mode. It’s the AF point selection display for the OVF.
Is the menu button “dead”, too? If not, then make sure the power switch is not in video mode. Switch the top dial to “P”. Go into the menus, find and select the option to restore factory default settings.
Hi Bill. I am not sure that the power switch has an integrated video function in the T7, I think that is specific to the R7.
I certainly agree that the display is working to at least some degree, but they will got get much joy with no card in the camera, as the example image seems to show.
OP states "I was shooting with this camera this weekend, and the LCD screen cut out near the end of my session.", so I would assume that at the time the problem arose there was a card in the camera.
