Note on the main board replacement
When replacing the main board, take read/write procedure of the gamma adjustment data and color shading cor-
rection data.
The “gamma adjustment data” and “color shading correction data” of each panel have been adjusted precisely at
the factory to match the characteristics of each panel.
When you replace the main board, you need to read out the "gamma adjustment data" and "color shading correc-
tion data" stored in the memory IC on the previous main board and write down them into the memory IC on the new
main board. By this way, the projector is enabled to reproduce the picture which has the properly adjusted gamma
characteristic and color shading correction.
Use "Projector Service Tool" software for Read/Write of the gamma adjustment data and color shading correction
data. This tool also enable to correct the color shading and gamma characteristics.
