Further to my posting on the horrid rattle. Just removed the VIS unit and tested the arm, the arm is fine. On taking the pcb out and putting an eye glass to it I find something.................one of the v3 switch legs had broken away. Not obvious at first as it was such a clean break, so requires a little solder and all's well
