Thanks for the reply .. here's what I have tried so far :  
  
 
Tried another TV for both live view and playback of recorded , same issues , colours all wrong. 
Swapped the scart adapter , currently the route is bnc to phono into scart adapter. Also tried phono straight into yellow video input - same results. 
Tried swapping cameras , same problem. 
Used a camera indoors under natural lights - my skin appeared blue , and blacks appeared pink!  
Interesting thing is , early morning the colours appear correct - after about 9am it all goes down hill again. 
 
  
Ive included a few more stills , just to give a better  idea. 
  
  
 
As you can see form this one - the car appears green , its actually light blue! And the brickwork is blue! 
  
 
  
And in this one, my nice blue grass!. 
  
Any more ideas guys? 
  
Jim
