LP340/340B/350 Service Manual 65
To orient a DMD on the optical engine
1 Place the DMD on the DMD opening in the optical engine. The rear and inside edge of the DMD
is keyed to fit the engine housing. See the illustration below.
Make sure the DMD fits into the opening in the proper orientation. The DMD should fit loosely into
the opening, and the pins on opposite corners should fit into matching holes on the engine
casting.. Do not force fit the DMD into the opening.
If the DMD is backwards, the controller ECA may be destroyed when the projector is powered up.
