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
COMPO input.

22

Checking colour related
performance

1. Receive the colour bar signal.

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

23

Checking of picture-related
performance

1. Receive the monoscope pattern
signal.

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

24

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.

25

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.

26

Checking of thermistor
performance

1. Heat the thermistor with a hair
dryer.

1. Make sure the temperature is displayed.

27

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.

28

Vertical line level check

1. Receive the RGB signal. 10-step
grey-scale

1. Compare with the vertical line boundary
sample, and it must be at the boundary
sample or less. In case that it is bad, adjust
the PSIG-L of the item 3.
However, it must be within the range of 190 -
200.

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.
