On a TZT16F (TZT3) has a HDMI input that lends it self well to TV but TZT2 15" does not have an HDMI input. Composite RCA doesn't lend itself to TV very well because most TVs don't offer RCA Composite video output. If yours does, it would be extraordinarily rare. When making an analog RCA connection, one must go in the settings [HOME - SETTTINGS - CAMERA - and turn ON the port for which you are using] Once the port has been activated you should be able to setup a camera hotpage and swipe up from the bottom to choose that video source.
