Hi Lynz - the cable adapter that I've used is shown below - has a docking end to the iPad and an HDMI input at the other end; plus, a USB connection for charging if needed; an HDMI cable is needed which will carry BOTH HD video and audio to your TV; of course the latter will need to have an HDMI input, and as already stated HDTVs have multiple inputs and the correct one needs to be selected to view your iPad on the TV.
Now you appear to have a standard definition (SD) composite adapter (i.e. yellow carries the combined video signals, thus just SD; and the red & white RCA jacks are for standard stereo audio). But there are other options, such as 'component' video (3 cables) which is also HD video, but needs additional audio inputs. S-video is yet another choice for the video signal (and requires audio cables).
So basically more information is needed about: 1) your TV, i.e. what type of inputs relative to the above discussion are available; and 2) does your composite adapter have an end that docks w/ your iPad - this should be easy to resolve so more information will help - good luck!
