Thanks Beaky
I got the board 2 days ago and had a chance to install today and test - PERFECT - so a big thankyou as the screen works and the volts are up to 5.22volts at the test point of the board and on the white block resistor the the volts on one side was 5.22 and other side 5.40. Also that dmd plug is so much more positive fit - nice and firm.
So very happy, thank you very much Beaky. 
your welcome
other than replacing a few connectors the only other part i changed was the regulator I.C which brought the voltage up to 5.22 volts on the 5 volt rail at the power supply.
was the dmd display connector fitted to the upgrade cable that you sent me already fitted to the cable when you bought it or did you fit it before you sent it to me?
The connector was already fitted, therefore because not pressed in properly no volts to the display
