Well i have replaced IC11, fitted a new LM1889N, replaced all the Electrolytic caps on the Power Board and CPU Board, I have replaced the Tantalum capacitors on the board, replaced RV1, replaced C7, replaced the Ceramic Caps on the Chroma output feed just in case. I swapped out the SAM and it wasn't that either. Nothing has made any difference to the output. Somehow the Chroma feed from the LM1889N is not getting outputted properly. I don't have all the kit to help find the exact fault and i have tried a belt and braces approach which in this case has sadly failed. If there is anyone who can offer another suggestion i would be grateful.
I don't want to throw anymore money at this if i cannot fix it and am reluctant to cough for a VDG unless i know it was the definitely the problem.
If anyone can repair D32's i would gladly like to talk to them.
The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
contact him there he will repair the D32 and also offer 64k upgrade and he can install custom roms and a pcb so you can switch from coco 2 to D32 (with 64k) with keyboard matrix fix.
he also was working on an RGB board for the D32 so he should know how to resolve your issue.
Prime on here knows him very well they both worked (i believe) on the Dragon MMC in some part.

I was actually the one developing the RGB borard, though Bas was beta testing. Project was shelved as couldn't get it to work to my satisfaction, and board was a bugger to assemble.

Yes he and Richard Harding did extensive testing and helped development.
