Many phones have TV out facility but the cable does not come in standard packaging box. We have to buy it additional. It would cost hundreds for original cables I have made a TV out cable for my Nokia N79 long back. Same trick could be applied for other brands once you know the pinouts of 3.5mm jack correctly. All you need is 1) 3.5 mm HEADSET connector with 4 contacts. ( u can buy headsets of china mobile phones having 3.5mm jack for that) 2) An old AV cable used to connect DVD players with TV(costs only 40 for new) The microphone contact of the 3.5mm jack is used for carrying video signals to TV (for nokia). Other two contacts are used for left and right audio channels. The fourth contact is the common ground for video,left audio,right audio. The contact line designations starting from the tip of 3.5mm jack is 1--right audio 2--left audio 3--mic (video: in our use) 4--common ground Guys take up your soldering irons and assemble yourself Enjoy videos and movie files on your
