A "ground connection" between the monitor and CD32 is essential 
as the signal return path, but this should be part of the cable!
Are any wires broken?  
Are the syncs also connected?
What terminations are there?  Perhaps there are small value 
coupling capacitors in lines not expecting to see 75ohm loads
at the monitor?

I am surprised you say the screen is blurry on composite video,
I use a 21" SONY TV with CD32 on direct PAL video to SCART 
(NOT RF) with excellent results, and have also tried the SVHS 
route which was slightly better still, but a borrowed lead  :^)
I agree that RGB should be much better, but it does not seem
that way from CD32 (I tried a nasty fiddle direct from CD32 
motherboard to the SCART which may have made things worse 
since it was not properly buffered)
