@inglewood the err99 is a very generic error code. It can show up when there is a lens incompatibility, a battery problem, a shutter problem or bad contact between the body and the lens. I don't think it is related to your LCD issue. That actually looks like a bad LCD display. It will start to get double vision when it warms up. I suggest you consider replacing the display and while you work on your camera, make sure that the ribbon cable and connectors are not bend or corroded. [guide|77828]
