Note on Main Board Replacement
Take the following setting when the main board is
replaced.
- Adjustment ship data setting ( Color Shading Correction
Setting, Gamma Correction Setting)
Adjustment Ship Data Setting
This projector stores “Color Shading Correction Data” and
“Gamma Correction Data” in the memory (IC1391) on
the main board. Those shipping data have been setup
according to the optical characteristics of the mounted
LCD panels preciously in the factory. When replacing the
main board, you need to read out the those setting data
stored in the memory ICs on the previous main board
and write down them into the memory ICs on the new
main board.
By this way, the projector enables to reproduce the
picture which has properly adjusted color shading
correction and gamma correction. If it is not possible to
read out the data, or replace the LCD/Prism assy , you
seed to write the initial data which is setting the typical
characteristics of the LCD panel into the ash memory
on the new board.
For further details, refer to the operation manual of the
software [PROJECTOR SERVICE TOOL v4.2].
