My sx260 has screen black and photo black that is intermittent and follows pressing on the round mode selector dial on the back. When it goes black I can make it come back by putting slight pressure on that dial. I don't know where the pressure on the dial is acting to solve the issue. It could be a connection there or someplace else. I understand that this is a not uncommon issue. I have used this camera so little over the years. It has lived in a desk drawer. So this problem seems to be defect in the camera.
