1. Initializing the EEPROM
1) Press SW2002 to enter the process mode.
2) Execute the S1 command on the SSS menu. (The S1 command initializes the PC board alone. Do
not execute the S2 command because otherwise the adjustment data other than the PC board will be
initialized.)
2. Adjustment of input signal level
2.1 Setting the oscilloscope
Set the oscilloscope range to DC 1V/div. and 5 ɵsec/div.

2.2 Connecting the PC interface
1) Connect the analogue output (signal generator) and the DVI-I connector (INPUT 5 of the projector)
with the cable (DSUB-DVI).
Set the INPUT SELECT of the projector to INPUT 5 (select the analogue RGB on the menu.)
2) Set the signal generator to the XGA mode (1024x768, 60 Hz, 32 tones). Adjust the output amplitude
to 700 mVp-p between the black and white levels (terminated with a 75-ohm impedance).
3) Turn on the power.

2.3 Adjustment of A/D (RGB)
1) Press SW2002 and enter the process mode.
2) Select AD-AUTO from the A/D (RGB) menu.
3) Press the ENTER key on the remote control. The AUTO adjustment is performed.
4) Exit the A/D (RGB) menu by pressing the UNDO key on the remote control.

2.4 Adjustment of A/D (COMP)
1) Select the A/D (COMP) menu.
2) Set G-BRIGHT to the numeric value of G-BRIGHT of A/D (RGB).
3) Adjust CB-OFFSET to 20.
4) Adjust CR-OFFSET to 20.
5) Exit the A/D (COMP) menu by pressing the UNDO key on the remote control.

2.5 Adjustment of color wheel index
1) Input the pattern for adjusting the color wheel index to INPUT5.
(Refer to "3. Color wheel index adjustment" in the "Adjustment method of each part" section.)
2) Select CW INDEX from the DLP menu.
3) Adjust so that the lamp gradation patterns of R, G and B become smooth without noise.
4) Exit the PLD menu by pressing the UNDO key on the remote control.

2.6 Select S5 from the SSS menu and press the ENTER key on the remote control.
Check that the OSD display of the set 5 appears.

Ι. Adjustment conditions

1) Adjustment item: Process mode: 

DLP menu 
GAMMA, 
R-GAIN, G-GAIN, B-GAIN

2) Input signal: Component video 75% white signal

1. With the component video 100% white signal, adjust the output to 0.7 

± 0.05 Vp-p

(excluding the synchronouspart.) (The sync signal is 0.3 Vp-p.)

2. Next drop the image signal output to 75%.
3. Input the signal to INPUT5 (DVI-I connector).

3) Target adjustment chromaticity

x = 0.290 

± 0.005

y = 0.311 

± 0.005 (Color temperature: 8500K, +6UV)

ΙΙ. Adjustment procedures

1) Select GAMMA from the DLP menu and set the value to “6”. (Initial value = 6)
2) Set R-GAIN, G-GAIN, B-GAIN to “96”. (Initial value = 95)
3) Background adjustment

1. Project on a 40-inch screen, and observe the chromaticity in the center with a

colour meter.

2. Fix G-GAIN to 95.
3. Adjust the x and y values to the target adjustment chromaticity with B-GAIN.

However, the adjusted value is up to 115 at maximum.

4. Adjust the x and y values to the target adjustment chromaticity with R-GAIN.

However, the adjusted value is up to 115 at maximum.

When the R-GAIN value is 115 and the x value cannot be adjusted,
1) Lower the B-GAIN and adjust to x = 0.290.
2) Lower the G-GAIN and adjust to y = 0.331.

5. Check that the middle gradation is not greatly deviated.

4) Exit the DLP menu by pressing the UNDO key on the remote control.
