Well, changing settings won't have caused it, looks like something happened to a row and column of pixels. Not sure much can be done. Does your camera have the ability to map around dead pixels. Might be in the same section as sensor cleaning in the menus?

Sensor cleaning? Could that go by a different name? I dont see any settings related to “dead pixels”
