2-4. Adjusting the DTV
1) Set the switch to the BNC input terminal of INPUT1
2) Set up a signal generator in 1080i 60Hz mode white signal.Output amplitude makes space
between black – white 700mVp-p (75ohm terminated) .
3) Connect the analog output terminal of the signal generator and BNC connector (the
INPUT1 terminal of projector) with the cable.
4) Make G-BRIGHT of DTV the numerical value, which is the same as G-BRIGHT of A/D.
5) Set up the level of the signal output in 53%, and adjust with CB-OFFSET of the DTV in a
place to become bit less condition.
6) Set up the level of the signal output in 53%, and adjust with CR-OFFSET of the DTV in a
place to become bit less condition.
7) After adjusting the CB-OFFSET and CR-OFFSET, 6 point adds G-BRIGHT.
8) Press the S2601, to comes out of the process mode.

Servicing precautions
(1)If the convergence gets out of spec in servicing the set, call the process mode and select
the following group and subjects.
Group: NOKO
Subject: R-CNV-H, R-CNV-V
G-CNV-H, G-CNV-V
B-CNV-H, B-CNV-V
(H and V are for horizontal and vertical adjustments, respectively.)
Adjust the above settings to the range of 0 to 4.
(2) When entering the process mode, select the following group and subjects too.
Group: VIDEO1
Subject: SET-UP B
SET-UP C
Make sure the SET-UP B and SET-UP C settings are 10 and 2, respectively. To exit from the
process mode, be sure to take either of the following ways: Go to the subject SET-UP 1 and
quit the mode, or select Group:
SSS and Subject: S4 and quit the mode.

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.
