A:Answer Hi Pat47, Thank you for your inquiry! If you will connect this TV using a composite video cable(red, white, yellow), you need an Analog Extension cable or connect them using a composite video/audio cable. The 3.5 mm jack of the Analog Extension Cable has 4 poles. Here is a link to show you the input and cable needed, its on step 9.
