Hi Guys,
Thanks for your replies, i've sort of solved it. In the afternoon of working with my old laptop I got everything set up and running with no problems on the tv but last minute in the evening I changed from using the tv to using a moniter instead and had trouble with the color on the tv the next day. The tv with the same lead on my other computer is working fine and also my old laptop with another tv works fine so I've come to the conclusion the it's the tv struggling for some reason with the signal off the old laptop although it used to work fine but I guess something inside the tv must be breaking down with old age!
