Do you have access to the chamber such that, after powering everything off, you can manually push (careful, those worm screws are not great with jerky motion...) the stage along negative Y and park it close to or beyond the home?  When everything is powered back, it should initialize and hunt for home. If the motor turns but fails to initialize, you might have a broken stage positioner.
