Hi,
If you open up your CD32, you will find a number of PCB solder pads called TP9 near the expansion connector. This provides RGB video and Hsync, Vsync and CSync signals and of course ground.
According to the
CD32 FAQ , you need some 47 ohm resistors on RGB and you need to bufffer CSync.
If you are handy with a soldering iron, get busy!
