4. With the G-LCD panel's screen center as refernce, adjust the R-LCD and B-LCD panels.
5. Finally tighten up the convergence lock screw "d".
Notes :
1
The eccentric cam is used for convergence adjustment.
This means that the cam's turning and the linear movement are not always uniform.
2
This model is not equipped with the LCD image adjustment mechanism. This is because the cross-dichroic
prism is used for image formation. When the LCD panels all get into best focus, the images are almost
completely converged.

a small adjustment range in the Z direction.

Adjusting the optical axis of the mirrors (M1, M5 and M4/M6)
The optical axis must be readjusted if an eclipse happens with the R. G or B mirrors. Generally speaking,
this adjustment is needed when any of the internal optical components has been replaced.
Adjustment procedure required when any of the panels has been replaced or the convergence has been
adjusted
(1) Disconnect the flat cables of all the LCD panels.
(2) Let the lamp light up.
(3) To adjust the G mirror, shield the R and B mirrors with shielding plates (You can use a business card or the like to
block the light).
(4) Loosen the lock screw of the M1 adjust lever.
(5) Looking at the G image on the screen, turn or slide the M1 adjust lever until the eclipse on the screen disappears.
Tighten up the screw.
(6) To adjust the R mirror, shield the G and B mirrors and adjust the M5 adjust lever. For the B mirror, shield the R and
G mirrors and adjust the M6 adjust lever.
(Take the same steps 4 and 5 above.)
(7) Remove all the shielding plates to have a white image.
Make sure there is no eclipse.
