This points to a hardware fault in the image-capture path, not a settings issue. Because the menus display normally but both live view and saved photos are completely white, the problem is likely with the sensor, its connection, or the camera’s main processing board.

In other words, the camera can still power on and display overlays, but it is not receiving or processing normal image data from the sensor. A loose/broken sensor cable, failed sensor, or mainboard fault are all plausible causes.

Since the issue affects both preview and recorded images, it will likely need professional service rather than a reset or menu change.
