try this for your problem,
Info from kasar's guide:
Step 7 - getting the video/audio signal wireshttp://kyorune.com/modding/file.php?art=84&file=44
and use this image to connect your gc wires to your prone lcd:http://kyorune.com/modding/file.php?art=17&file=3
this step i have or had done it, but my gc won't output any video/audio to screen.
i thought my four socket 2 connections were bad, but from fixing them to mt screen's port and testing it out with my prone unit, it works fine??
i got perfect sound/video!!!
so my connections weren't bad at all only my gc board was messed up maybe somewhere.
