hi bro.. ive done many iphone 4 back camera not working and luckily all done.. try to check this area as shown picture below. if all the component around the camera are good as it looks like no burn or not wet, do continuity check specially all pins of connector because most of time have cut line thats why your camera got black display. the best I can advice to you is get good and working board and compare the continuity and voltage of each capacitor, resistor around the connector.
