May I ask the Tv brand and model for 1. Also on cameras you only need to hook up th video/yellow cable to the video input and the audio/ most likely the white cable for sound to the white input jack on the back of tv for sound.

Now the white cable might also be red.

When you do that you need to see what input you connected to so you can set the tv to that input so you can see the camera.

Hi,
Plug yellow video pin in yellow video input of tv and plug audio pin of camera cable in white audio pin of tv.
Not sure what is model and brand of your tv yet above info will work. TV would have red-white pins as audio L-R inputs so use either white or red, its your choice but only one speaker will give you camera playback sound. Yellow pin will be hooked in yellow video input jack in tv.
Select that AV input in tv with its remote where camera is hooked to get camera picture in tv.
Let me know if you have additional question.
Thanks.
