Hi it was a grounding problem but not where I expected, it was where the mother board should contact the metal case where the two controller inputs are on the board, there are two rows of brown caps, those two grounding contacts on the board connect with the case, noticed by accident when I pushed down on the board on the front and could not correct it so I soldered two wires one on each end on the neg terminals and have grounded them to the metal case screw it now opperates perfectly. Be good to know if you have the same problem again from Members
Thanks again John, if not clear let me know and I will try to take a picture before closing case.
