No it hasn't unfortunately. However it seems I've narrowed it down to the TV having issues. It seems to have it's ports 1 and 2 transposed !? And can not sync the picture properly either.
To my surprise I did spot that the TV has a VGA port. I can't find a male VGA to male VGA cable but might go purchase one and try that. Trouble is there is a feeling of throwing away good money after bad. Not that the cables seem to be the issue, but they aren't going to be usable with that TV.
