Adjustment of COMPO
white balance

1. Feed the DTV monoscope pattern
signal.
2. Select the following group and
subjects.
Group: DLP
Subjects: C-R1-BLK, C-B1-BLK

1. Using the set's control switch or the
remote controller button, adjust the settings
to have the same white balance as on the
standard monitor.

18

Adjustment of sRGB white
balance

1. Feed the RGB 50% grey pattern
signal.
2. Select the following group and
subjects.
Group: OUTPUT1
Subjects: S-R1-BLK, S-R1-GAIN,
SG1-
BLK, S-G1-GAIN, S-B1-BLK, SB1-
GAIN
3. Have the BM-5 brightness meter
and the standard white board at hand.

1. Make the S-R1-BLK setting the same as
the R1-BLK one.
Make the S-G1-BLK setting the same as the
R1-BLK one.
Make the S-B1-BLK setting the same as the
R1-BLK one.
Make the S-R1-GAIN setting the same as
the R1-GAIN one.
2. Adjust the S-B1-GAIN and S-G1-
GAIN settings so that the chromaticity on the
brightness meter should be as follows.
x: .313±7/1000
y: .350±10/1000

C50 conditions set-up (

)

Correction procedure settings
Gradation 7: 

2. Lower-gradation correction value to be used.

Gradation 6:

0. Correction with correction coefficient.

Gradation 5: 

0. Correction with correction coefficient.

Gradation 4: 

0. Correction with correction coefficient.

Gradation 3: 

1. Upper-gradation correction value to be used.

Gradation 2: 

1. Upper-gradation correction value to be used.

Gradation 1: 

4. Initial value to be used.

Gradation 0: 

4. Initial value to be used.

For the model in question, select the name entered in (2) to start the colour irregularity
correction. If the set has its optical characteristics rather different from the standard ones or if
the set has some colour irregularity lines missing, do the teaching for that set in particular.
Use its specified correction coefficients in making the adjustment.

Checking and
readjustment of
white balance

1. The adjusting conditions for each
item are as follows:
For RGB input, see Item 7.
For video input, see Item 13.
For COMPO input, see Item 16.

1. Make sure the white balance is as
specified on the standard monitor.
For readjustment, proceed in the order
of RGB input, video input and

Checking colour related
performance

1. Receive the colour bar signal.

1. Select L1 in the process mode.
Check the performance of colour and tint.

21

Checking of picture-related
performance

1. Receive the monoscope pattern
signal.

1. Select L2 in the process mode.
Check Picture, Brightness and Sharpness.

22

Checking of RGB
performance

1. Receive the RGB signal.

1. Select L4 on the process mode.
Check Picture, Brightness, Red, Blue,
Clock, Phase, H-POS and V-POS.

23

Checking of off timer
performance

1. Select OFF in the process mode.
Make sure that the off-timer starts with 5-
minute display, counts down
1 minute for 1 second, and turns off when 0
minute is displayed.

24

Checking of thermistor
performance

1. Heat the thermistor with a hair
dryer.

1. Make sure the temperature is displayed.

25

Automatic sync
operation

1. Receive the phase checking
pattern signal.

1. Make sure that Clock, Phase, H-POS and
V-POS can be automatically adjusted in the
VGA/S-VGA/XGA mode.

26

Checking of USB
performance

1. Using the USB cable, connect the
set to a personal computer.

1. Using the remote controller, make sure
that feed and return operations are effective
on the screen of the personal computer.

27

Factory settings

1. Make the following settings.
Destination / Process adjustment /
Remote controller settings
North-American models: S4 "Factory Setting
4"
Domestic models: S5 "Factory Setting 5"
Other models: North-America: S3 "Factory
Setting 3"

How to Adjust the PC I/F unit
1. Initialisation of EEPROM

1) Press SW2601 to enter the process mode.
2) Execute S1 on the SSS menu. (By S1, the PC board alone is initialized. Do not
execute S2, or all the adjustment data, except for the PC I/F unit, is initialized.)
3) Make sure that the program version "VER. XXX" on the SPECIAL menu is the
latest one.

2. Level adjustments

2-1. Setting the oscilloscope
Set the oscilloscope's range to DC1V/div and 5µ S/div.
2-2. Connecting the PC interface
1) Connect the specified cable between ANALOG OUTPUT (on the signal generator)
and DSUB connector (INPUT1 on the projector).
2) Set the projector's input selector to INPUT1.
3) Set the signal generator to XGA mode (1024x768, 60Hz, 32-step gradation). Also
adjust the output amplitude (between black and white) to 700 mVp-p (terminated with
a 75-ohm impedance).
4) Turn on the power.
2-3. Adjusting items
1) Adjustment of RGB drive/gain
(1) Feed the window pattern signal that has 100% and 0% signals.
(2) Select AUTO among the A/D items in the process mode and make the
adjustments.
