S-Video Mod Schematic for the Schematic-Illiterate (For TG-16/Duo etc)

[pdiggitydogg]

I took it to a local repair guy. I can solder and add wires to stuff but I'm afraid of really messing around in a CRT. I don't know what I'm really doing in there...
He says its putting out only 6v, from the PSU. He changed some "misc parts" but is not being very informative. I should just pick it up... I don't think he really knows how to troubleshoot or trace an issue. He's asking for help on finding schematics.
It was flashing a picture, at startup for a split second, and then going black. Audio was working fine - I cycled the power a couple times and then the audio was super low (like caps).
I was getting the same result in s video and composite (currently no RGB and don't try VGA)
When it worked, this thing was great.
