Thanks John, I did as you suggested, the CPU fan was always active. It now works, having checked all obvious items, and with nothing to lose, I did the best trick known to hams...I gave a BIG wiggle on the video cable at the PC connector and after about a minute of wiggling, akin to just banging it ! I got a signal!
