robynb1,
Looks like your problem is the cable you are using for that port on the back of the apline.
The port I am assuming that you are using is the `audio out' port and will not send the video signal you are after.
You will need to use an AV convertor for this application (as the tv looks like a model that only supports RCA / composite)
Meaning... take the HDMI signal to a conversion box and then splitting it into the RCA you are after.

If the convertor does not provide the White and Red (Right and Left Channel Speakers) cables for the
audio... you will need to use a cable like the one you have on the 'audio port' in the same manner I suspect you had wired it.
