DL2 Motion Shut Down message and focus issue

I am getting a Motion Shut Down message in the status window of one of my DL2's which will not clear with a Power cycle or with a Motion Pan/Tilt Reset. This fitting is on the floor because the projector focus will not sharpen up at 100% zoom on a 9-12m throw. All other motion parameters appear to be responding correctly.

Has anybody had either of these issues before. I have cleaned all the lenses . . .

Any help/comments would be greatfully recieved.
