check

1. Receive the colour bar.

1.Select L1 of the process mode LINE.
Operation check of Colour and Tint.

13

Video-related operation
check

1.Select L2 of the process mode LINE.
Check of Picture, Bright, and Sharpness.

14

Operation check of RGB

1. Receive the RGB signal.

1.Select L4 of the process mode LINE.
Check of Picture, Bright, Red, Blue, Clock,
Phase, H-POS, V-POS.

15

Off-timer performance

1. Select OFF from the process mode LINE.
Make sure the off-timer starts with 5 minutes
onscreen and the set turns itself off in 5
minutes.

16

Thermistor performance
checking

1. Heat the thermistor with a hair
dryer.

1. Make sure that the temperature is
indicated.

17

Auto sync performance
checking

1. Feed the phase check pattern
signal.

1. In the VGA, SVGA and XGA modes,
make sure the Clock, Phase, H-Pos and V-
Pos settings can be automatically adjusted.

18

Delivery settings

1. Make the following settings.

19

Inspection of HTPC720P

At INPUT 5 (DVI-1 connector)
1. Receive the colour bar signal.
2. Receive the grey scale signal.
3. Receive the SMPTERP-133 signal.

Check that there is no abnormality with the
screen.

1. Initialising the EEPROM
1) Press SW2002 to enter the process mode.
2) Execute the S1 command on the SSS menu. (The S1 command initialises the PC board alone. Do
not execute the S2 command because otherwise the adjustment data other than the PC board will be
initialised.)
3) Make sure that the program version VER.XXX on the SPECIAL menu is the latest one.
2. Adjusting the levels
2.1 Setting the oscilloscope
Set the oscilloscope range to DC 1V/div. and 5 µ sec/div.
2.2 Connecting the PC interface
1) Connect the analog output (signal generator) and the DVI-1 connector (INPUT 5 of the projector) with
the cable (DSUB-DVI)
Set the INPUT SELECT of the projector to INPUT 5 (select the analog 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 Adjusting and checking the levels
1) Press SW2002 to enter the process mode.
2) Select the AUTO adjustment mode.
2.4 Adjusting the DTV
1) Feed the signal to the INPUT1’s RCA input terminal.
2) Set the signal generator to the 1080i 60-Hz mode with white signal. Adjust the output amplitude to
700 mVpp between the black and white levels.
3) Connect the specified cable between the analog output (signal generator) and the RCA connector
(INPUT1 of the projector).
4) Make the G-BRIGHT setting the same as the G-BRIGHT setting of Group A/D.
5) Adjust the CB-OFFSET setting of Group DTV to 20.
6) Adjust the CR-OFFSET setting of Group DTV to 20.
7) Finally press SW2002 to exit from the process mode.

Adjust it in the following 2 steps.
I
1. Adjustment item process adjustment DLP GAMMA
2. Input signal: component video 75% white signal 0.7 ± 0.05 Vp-p (synchronised part excluded.)
3. DLP GAMMA initial value 6
4. Adjustment procedure

1 DLP Change the numeric value of the GAMMA item from the initial value 6 to 0.

II
1. Adjustment item: process adjustment DLP R-GAIN, G-GAIN, B-GAIN
2. Input signal: component video 75% white signal 0.7 ± 0.05 Vp-p (synchronised part excluded.)
3. R/G/B-GAIN initial value = 95
4. Target adjustment chromatically x = 0.287 ± 0.005 y = 0.137 ± 0.005 (colour temperature 8500K,
+11UV)
5. Adjustment procedure
1 Project on 40 inch, and measure the chromatically of the centre with a colour meter.
2 Fix G-GAIN to 95.
3 In B-GAIN, adjust the y value to the target adjustment chromatically. However the adjusted value is up
to 115 maximum.
4 In R-GAIN, adjust the y value to the target adjustment chromatically. However the adjusted value is up
to 115 maximum.
5 Check that the halftone is not greatly deviated by comparing with the standard monitor.
The user adjustment value is adopted as standard for the standard monitor.
