Sorry if I am being a bit obtuse, but do you mean that without your defective IA00 card in your 861 all is OK (except you don't have unbalanced analogue inputs!!)? If so then that is great news. All you need to do is get the IA00 card repaired (almost certainly a failed voltage converter/regulator).
