Ok so I have a minor problem. I want to make a video out cable for the MT4GS. I have the right tools, and know-how. Anyways whenever I just use a 4 3.5mm male jack (has 4 metal contacts instead of 3, don't know what to call it), and use a rca cable and get it hooked up I can use it and it works fine sometimes. It seems that, when I get it working if I open the T-mobile TV app it shorts it out and stops the video out. And sometimes when I just plug it in to the rca port on the TV it acts like its shorting out. I don't have any shorts in the wire and no wires are touching to create a short. The only thing I can think of is maybe the voltage is going backwards into the headphone jack on the phone. Would adding a diode help with this? Anyone have any ideas or helpful information? Also to add I can get the audio out working from the phone to TV working fine, I just seem to have problems with getting video to work properly. I know I could always go and buy a cable, but I want to make one, because its cheaper.
