Thanks Jochen,

I am just trying to be sure I understand rather than finding out later that I've mis-understood something you've said.

Forgive me if this leads to confusion and what may seem as over complication.

I make it that pins 5,6,7 carry the video signal so it will be a case of adding these and also pin 12?

Thanks so much for all your help and re-assurance. You've been an invaluable help to me since I started investigating this last Friday.

Some people have the right intention, but boy do they get it wrong when it comes to giving advice!

I'll let you know how I get on.

Thanks again

M
