What to do when the DMD becomes dislodged from its location on the optical engine
Regardless of the precautions you may take, you might find that the DMD becomes dislodged from the
optical engine when you remove the controller ECA. Be careful if this happens. Improperly handling the
DMD outside of the optical engine could result in replacing both parts. The DMD and optical engine come
in sets, both matched to provide the best image.
If the DMD falls to the floor, chances are the shock of the fall has ruined the DMD. You can attempt to
retrieve the DMD and replace it on the optical engine. However, you’re likely to see a broken image or no
image at all. The optical engine will likely need to be replaced.
If the DMD falls on the workspace, you may be able to replace it on the engine with no ill effects if you
follow the proper procedure.
