OK so no thanks to this forum I have Fixed the issue ..
[b]For anyone else who might have this problem  . The ADC 3870 16 pin chip needed re flowing .. I heated the area with a rework station until the solder went shiny (Melted) let it cool then ran the self calibration which it passed first time ..
so look for dry joints and por solder..
Good luck
