below, tighten the fixing screws or
wing nuts for each lens with a torque
of 1.67N.m(7Kgf cm) ~ 1.18N.m(12Kgf
cm).
(Do not turn the lens cylinder after
having a screw and wing nuts
tightened.
Also do not tighten the screw too
much, otherwise the lens will be tilted
too muchor the screw will be broken).
(2) Apply covers to each colors of R, G
and B lenses. and project a single
color beam on the screen and adjust
in sequence.
(The adjustment order of R, G and B
is only an example.)

2.16 SUB BRIGHTNESS ADJUSTMENT
Adjustment preparation
(1) Pre-heat 20 minutes or more before the
adjustment.
(2) Receive the color bar signal.
(3) The vertical incident illumination on the screen
should be 20 lux or less.
Adjustment procedure
(1) Go to “Sub Brightness (item No 38)” adj.
mode by using R/C.
(2) Adjust Sub brightness as following spec. by
using R/C.
* Note: During the SUB-BRIGHTNESS adjustment
mode, TV µcon changes the CONTRAST and the
COLOR controls to Min., but the other controls are
not changed automatically.
Make sure that the other controls are set center.

identified), increase the brightness by
19 steps.
2.17 WHITE BALANCE ADJUSTMENT
2.17.1 CHECK CUT OFF ADJUSTMENT
Adjustment preparation
Pre heat-run should be finished.
Sub Brightness should be adjusted roughly before
adjust the white balance.
Adjustment procedure
(1) Go to “SERVICE item No10” and press
key to enter CUT OFF adjustment mode by
using R/C.
(2) Check the each line is just appearing.
(3) If some of line is/are brighter/darker than
others, redo cut off adjustment again.
(4) Press key to return to normal mode.
2.17.2 WHITE BALANCE ADJUSTMENT FULL
WHITE WINDOW SIGNAL
Adjustment procedure
A) High Light W/B adjustment:
(1) Receive signal for High Light white balance
ADJ.
(2) Adjust the white balance to 14000K +0 MPCD
(X, Y) = (0.270+/-0.001, 0.280+/-0.001) at the
screen center by using R/C. Use item No. 39
(R DRV) to adjust X, item No 40 (G DRV) to
adjust Y.
B) Low Light W/B adjustment
(1) Receive signal for Low Light white balance
ADJ.
(2) Adjust the white balance to (X, Y) = (0.264+/-
0.001, 0.270+/-0.001) by using R/C.
Use item No.41 (R CUT OFF) to
adjust X, item No.42 (G CUT OFF) to adjust Y.
Do NOT change the item No.43(B CUT OFF)
setting.
Repeat A & B two or three times.

* Use signal without color burst. If it is not
possible, use PAL signal and turn off comb filter
in User Menu.
(5) BLUE defocus ADJ. should be finished.
(6) The vertical incident illumination on the screen
should be 20 Lux. or less.
Note: Window pattern must be used for this process.
Using a raster pattern will not give an accurate
adjustment.

2.18 SUB PICTURE ADJUSTMENT
Adjustment procedure
(1) Observe P852 on the CPT P.W.B.
and change the SUB CONTRAST
(Item No. 55) of service mode by
using jig R/C and adjust so that the
amplitude of the sub-picture is the
same as that of the main-picture.
(1) Preparation pre heatrun should be finished.
(2) Input a window pattern signal like below to the
AV1 and AV2.
INT Y = 0%
EXT Y = 0%
INT C = 100%
