Manual Structure
Purpose of this manual
This manual is the Service Manual of the Data Projector VPL-FHZ55/F420HZ.
This manual contains the service overview, adjustments, spare parts, block diagrams,
schematic diagrams and board layouts.
The service of the SA and SB boards on this unit are basically performed by the
replacement of board.
Therefore, the schematic diagrams, board layouts and electrical parts list of the SA
and SB boards are not contained.
It is required to replace the LA and LB boards as a laser unit assembly LEO because
they cannot be replaced as an individual mount board or a mount part. Therefore, the
schematic diagrams, board layouts and electrical parts list of the LA and LB boards
are not contained.
