    Thanks that would be great.
    Do you have the programming cable in stock? I will buy one at your store today also. (if not i will look around locally for one)

    I checked under a jewellers loop and the board looks good. No shorts and all good solders.
    I have confirmed the fault is internal to the 4 digit display unit by removing it and tested it on my breadboard. Discovered that the d segment of A3 does not light when properly driven. Other combinations show ghosting on the offending digits.
