The Optical Engine and Main (MA) Board are paired together as a single service

part. Neither is available separately. For service that requires the replacement of
either the MA Board or the Optical Engine, both components must be replaced
together.
The component parts of the Optical Engine require mechanical installation
positions to be adjusted in relation to each other. In addition, the control circuit
also has its own unique characteristics, such as display signal output drivers, that
differ from projector to projector. There are also unique differences in each
optical system mechanism, such as in the light valves.
In order to obtain the optimum display, it is necessary to eliminate these
differences in electrical and mechanical characteristics as well as to make
mechanical adjustments. The various correction values are set at the time of
shipment from the factory and are stored in ROM on the MA Board.
Always replace the Optical Engine and MA Board together as a matched pair.
Do not disassemble the Optical Engine.
Do not replace the component parts of the Optical Engine with parts from
other Optical Engines.
