[Wii2hdmi On Xbox]

I'm trying to solder mine internally and I'm getting video and sound but the video has diagonal lines and a slight pink-purple tint.

I have soldered and re-soldered the connections. I changed the WiitoHdmi board to a different one same problem. I tried the a/v port with a component cable and get the same issue IF the WiitoHdmi board is connected. If I Disconnect the wires from the motherboard picture is good.  I noticed others seemed to be having a similar problem with interference. The wires i used are 30 gauge and are somewhere around 6" in length.

So my questions are these: 1.  Is the diagram of the XBox mb  diagram pin-outs correct? 2. Do I need to connect more ground wires?,  or 3.  Is it the WiitoHDMI adapter?
