Introduction
When replacing lamps, check the model name of replacement lamps (sold
separately). Check the model name of replacement lamps against the repair parts
list.
１
Warning
The lamps used with this LCD projector are high pressure mercury glass lamps. High
pressure mercury lamps break with a loud noise from shock or damage, or from
deterioration after lengthy use. When they cease blinking it indicates that they are
about to fail. Different lamps have widely varying life spans, and sometimes they
break or cease blinking shortly after being put into use.
In addition, when the lamps break, glass shards can scatter into the lamp housing,
and gases, including mercury inside the lamp, can escape through the ventilation
holes of the projector.
・ Lamps sometimes break when subjected to shock or damage, or during use.
Please handle them carefully.
・ Using lamps for lengthy times beyond their replacement time increases the
chance they will break. When an instruction appears to replace a lamp, please
follow the instruction and replace the lamp promptly. Re-using old lamps (used
lamps) leads to breakage. Please do not do this.
・ In case a lamp does break (with a breaking sound), ventilate thoroughly,
vacuum up any gases emitted from projector ventilation holes, and make sure
nothing gets in your eyes or mouth.
・ Follow local ordinances and regulations regarding disposal of used lamps.
Generally they are classified along with other glass and glass bottles for
disposal purposes. However, some ordinances require separate sorting and
collection for lamps. Please be aware of this possibility.
・ Please do not use lamps with the lamp covers removed.
Lamp Replacement Indicators
Projector lamps have a finite usable lifetime. Images can become dark and discolored
with extended use. We recommend prompt replacement.
The lamp needs to be replaced when a “Lamp x Failure” or other lamp problem message
appears, or when the lamp indicator flashes red when the power is on.

Uniformity *1 and gamma adjustments
*1 : Formerly referred to as “purity adjustment.”
(1) Backup Pre-Replacement Board Adjustment Data
All adjustment data is stored on the main board (except for certain data that relies on the
panel optical properties, which is stored in the drive board). Consequently, if the prereplacement main board adjustment data is transferred in its entirety to the postreplacement main board, it should be possible to restore settings to their previous state.
Main board data backup is performed using a PC.
Please refer to the “Data Backup Software Operations Manual” for detailed information
about the backup method.
【Warning】
If the main board error is fatal, and if data backup is not possible using the method described above,
please return the board to the manufacturer.
The manufacturer will repair the board, read off the adjustment data and communicate it to us.

(5) Transferring Backup Data to New Board
After the new board is physically installed, use the “data backup software” to transfer data
backed up from the swapped-out board onto the new board. Please refer to the “Data
Backup Software Operations Manual” for detailed procedures.
Data not to be transferred
Regarding 「ADC INPUT PRESET」
」
・ ADC Input Preset is the adjustment value for the AD converter input level. This adjustment is
main-board specific, and so is not backed up or transferred using data backup software.
・ Main boards supplied as service parts are shipped from the factory with pre-set adjustment
values. There is no need to readjust the values after replacement. You should rewrite the
value on the attached adjustment data sheet to the new board setting values. The
adjustment method is described below for reference.
Adjustment Content
1
Attach a signal source and input a signal in which black
(minimum level) and white (maximum level are displayed.
The input signal has a vertical sync frequency of 60 Hz
regardless of the display resolution.
Remarks
Use a high-precision signal generator
as signal source, making sure to use
it with the image output shown
below.
Signal amplitude : 0.700±0.002Ｖ
Black setup : 0.000±0.00１Ｖ
2
While pressing ADJ, press the SUB key to display the
service person adjust menu. Set the mode number to “0."

5
For each primary color display, start with the maximum
value and work downward. Do the various adjustments
when the black area of the input signal turns white.
6
Go to amplitude adjustment as follows: FACTORY
ADJ. ADC INPUT PRESET INPUT LEVEL.
7
For each primary color display, start with the minimum
value and work upward. Adjust at the points where the
100% white area of the input signal turns black.
8
Press the END key to close the service person menu.

Detailed Failure Assessment Methods （（（（
Detailed Troubleshooting））））
When conducting failure inspections, first choose the phenomenon in the
“List of Failures” that most closely matches the observed anomaly. Then
identify the specific anomalous location based on the events that occur as
a result of that anomaly. This chapter examines as much as possible the
anomalous phenomena that are most likely to occur, identifies likely
sources of failure, and provides a flowchart of the process.
Sometimes it happens that replacing the component you think is the
source of the anomaly fails to resolve the problem. If this happens, make
sure to reinstall the replaced component before replacing the next
component.
In addition, if an anomaly recurs during assembly replacement, you must
first reattach the original assembly and see if the anomaly happens again.
The cause of the anomaly sometimes is not the assembly itself, but rather
a connection flaw or connection point degradation from use.
If the anomaly recurs after restoring the original assembly, check the
connections thoroughly.

Failure Display Functions
If a failure condition is detected, it will be displayed in some combination of the ON Indicator,
the Failure Indicator, and the Service Lamp.
In addition, if an anomaly other than these failures is detected, it will be stored as log data in
projector memory, and can be displayed in the menu screen.
ON Indicator
Indicates power and set in operation.

Move slowly.
【Warnings】
・ Make sure in Step 2 that you spray until the white mist stops coming out. The white
mist will cover the mirror with cloudy impurities.
・ Make sure in Step 3 not to tilt the can downward. If you do it will spray out white mist
used for cooling, and this will cover the mirror with impurities.
・ Move the spray can slowly. If you move it rapidly it will spray out white mist.
・ Blow away dust from the entire mirror surface without attaching the nozzle.
<Warning (2)>
Checking the Mirror Surface for Dust
・ It is of utmost importance to thoroughly remove dust, because if there is any dust
residue, the next cleaning operation will damage the mirror. Dust will scratch the
surface of the mirror just like sandpaper powder.
・ Look closely to make sure there is no dust left on the mirror. （This is easiest to do by
looking at the mirror from an angle with the all-white screen projected on the mirror.）
Almost always there will be some hard-to-clean dust residue. Put the spray can
nozzle near that dust and blow it away completely.

Inspection Methods
5.2.4. Projector Reflecting Mirror (Front Surface Mirror)
Cleaning Method
<Warning (3)>
Checking the Mirror Surface for Damage Before Cleaning
When checking the mirror surface for damage, be sure to turn off fluorescent lighting in the
room, display the projector all-white screen, and view the mirror surface from an angle. This
method allows you to check for shallow score marks on the mirror surface (normally hard to
see).
If there already is damage to the mirror surface, document the damage condition.
The reason for documenting the damage is to make a final judgment as to whether mirror
cleaning will produce further damage. For this purpose, document the condition in as much
detail as possible.
1
Either wash your hands thoroughly and swab them off, or wear never-used protective gloves.
Use scissors to cut the cotton swabs into a readily usable size (about 10 cm x 10 cm).
5cm x 5cm is OK if the dirty surface area is small.
Absolutely do not tear the cotton swabs. This produces a large amount of fiber dust that is a big
problem to clean off later.
2
Soak the cotton swabs completely in filtered water or distilled water and gently wring them out.
If you don’t wring them out enough, wiping the mirror clean will leave water droplets.
3
Use the cotton swab to wipe the dirty surface horizontally, touching it gently with pressure so light
that you have no sense you are pressing against the glass (1st time).
Only wipe the dirty area when cleaning. Wiping the area that is clean can cause damage.
Absolutely do not reuse cotton swabs a second time. Use a new swab every time you wipe the
surface.
Also, check as you work that there is no damage in the wiped areas (see Warning (3)).
4
Next, take in one hand a piece of cotton gauze soaked in filtered water and gently wrung out, and
take in the other hand a piece of dry gauze. Wipe the surface a second time as described in Step 3
above. (Wring out the swabs in the same manner as in Step 3.)
Wipe water droplets left on the mirror surface with cotton swabs and soak them up immediately with
gauze. The gauze will also get dirty, so always use a new surface to soak up droplets.
The reason for immediately soaking up water droplets with gauze is that the droplets contain dirt
that was on the mirror, as well as dirt from the atmosphere that was dissolved in the water. If the
water droplets dry on the surface, this dirt will be left on the surface also. (see illustration below)

Cleaning with Alcohol Solvent (Ethanol)
Use scissors to cut cotton swabs into pieces about 5cm x 5cm in size.
Moisten the cotton swab with a small amount of alcohol solvent (about the amount that
will dry immediately after wiping), and wipe the areas with wiping streaks and residual dirt
(noticeable areas only), doing so gently, with no sense of pressing against the glass.
<Warning (7)>
Removing Residual Dust from the Mirror Surface
Before finishing the mirror cleaning process, use a safety duster to remove gauze fiber
waste residue from the mirror surface.
When you use gauze to soak up water droplets left on the mirror surface during cleaning,
tiny dust particles from gauze fibers are left behind on the surface. It is difficult to remove
this dust residue a half-year later at the next scheduled inspection, so make sure you do
so before completing the cleaning operation.

Inspection Methods (Cleaning, Parts Replacement
<Warning (6)>
Problem Assessment
If mirror damage has progressed compared to before cleaning, document it and file a
report with the (DMD) quality assurance department. (Verify whether the damage causes
image deterioration.)
There may not be any problem with the on-screen image even if there is some damage
on the mirror. However, a cleaning method that produces further damage will eventually
impact the image if repeated. Accordingly, you must report it to (DMD) quality assurance
and share your cleaning method expertise.

Adjustment Procedure Overview
The various distortions do not change in isolation. Rather, they affect one another as they
change. Every time the various adjustments are performed, the state of adjustment of all the
adjustments performed in the past have to be checked and readjusted as needed. As these
repeated adjustments occur over and over, the various distortions are corrected, and at that
point the single-screen position adjustment process (6-axis adjustment) comes to an end.
Next you must check for misalignment between adjacent screens and perform minor
adjustments.
Also, if there is localized distortion (see graphic), you should adjust
the mirror (see “6.4. Adjusting the Mirror” for details on mirror
Corner is elevated.

perform minor adjustments.
After adjusting and checking, go on to the next screen.
Please note the following items when making adjustments.

【Warnings】
(1) Make sure the axis lock screws (4 spots) are loosened, that fastener screws are
loosened, and that transport hardware fastenings are released.
(2) If when you are turning the adjustment screw you feel it tighten up again or if it won't
move at all, immediately stop rotating in the current direction of motion.
(You have already exceeded the adjustment range, so continuing to rotate the screw
will break the adjustment hardware.)
(3) Use the internal cross-hatch signal when making adjustments. Make sure you are at
the electrical center point before starting adjustment.

Adjustment Procedures
Gamma Adjustment and Uniformity Adjustment
Using Internal Signals
(1) Purpose
Perform the following adjustments using internal signals.
・ Adjust color irregularity in the screen of each projector.
・ Adjust color disparities between each projector to settings in the gamma table in
Drive COM.
(2) Basic Sequence of Gamma Adjustment and Uniformity (Color Irregularity)
Adjustment
The basic sequence of gamma adjustment and uniformity adjustment is described below.
This sequence must be followed the first time this projector is adjusted.
Performing uniformity adjustment alters gamma properties. As a result, when you do a
uniformity readjustment you must also do a gamma adjustment.
(3) Concerning Gamma Adjustment
The input signal voltage-brightness properties of LCD panels do not have a linear form, unlike
CRT properties. Gamma adjustment is the process of compensating for the I/O properties
(gamma properties) from low brightness to high brightness to bring them closer to the
properties of CRTs.
The gamma table is a table of input/output values used to perform this compensation.

The overall form of CRT gamma is shown below. The initial value is linear (Fig. C). In this
instance, the output value of VT gamma as described above is the same as the CRT gamma
output value.
Manually adjusting CRT gamma allows you to alter the final input value to the panel. This
makes it possible to perform the adjustment without worrying about panel burn-in, which is an
item of concern with VT gamma adjustment. Note that intermediate adjusted contrast levels
are interpolated to linear form (Fig. D).

(6) Concerning Uniformity (Color Irregularity) Adjustment
Color irregularity adjustment compensates for color irregularity in the screen to produce color
uniformity. This process also compensates for brightness irregularity in the screen.
This projector supports a maximum of five levels of color irregularity adjustment. Intermediate
levels are interpolated by an LSI in the projector.

During adjustment, intermediate
contrast levels are automatically
interpolated.

Used when adjustment from NORMAL Interpolation applied only near the
ADJ. is inadequate.
very low-brightness gray contrast
level displayed on screen.
Displays a very low-brightness gray
for adjustment, with contrast levels
displayed from MID to bright.
LEVEL FIXED ADJ.
Supports five levels of adjustment:
BRIGHT、MID（H）、MID（L）、DARK、
DARKEST.
Adjustments can be made at all
five levels, allowing for precise
color irregularity adjustment.
The following three adjustment modes are available for each adjustment method:
・ Macro adjustment (MACRO) : (5 x 5) adjustment points （white circles below）
・ Macro sub-adjustment (MACRO SUB) : (4 x 4) adjustment points （black circles below）
・ Spot adjustment (SPOT) : (45 x 35) adjustment points
Macro adjustment points （image diagram）
When you navigate MacroSub-MacroSpot, the adjustment range per single point
shrinks, resulting in more localized adjustment. Use each of the three modes separately
according to the extent of the color irregularity.
-
-
Sub-macro adjustment moves a marker to the middle of the macro adjustment point. If the
original color irregularity was smooth, macro adjustment should suffice by itself. If macro
adjustment alone does not yield good results, because color irregularity is spotty, or because
the irregularity is severe, use sub-macro adjustment before you use spot adjustment.
Spot adjustment works only on a very small area. It is difficult to get good color and brightness
balance, so we recommend it not be used except by very skilled operators.

Concerning the 5 Adjustment Levels
As discussed earlier, this projector supports five levels of contrast adjustment. In order by
brightness, these are BRIGHT, MID(H), MID(L), DARK, and DARKEST. The values of these
five adjustment levels are set at the factory using an automatic color irregularity adjuster. The
remote controller cannot be used to alter the adjustment levels.
”Output” is fixed for these adjustment levels (see illustration). Changing the value of
DRIVE.COM causes a fluctuation in the value “*/255,” indicating the input value displayed
when entering adjustment mode. However, there is no change in “output” for the adjustment
points.
An interpolated linear value compensates for color irregularity between these levels.

5 Level Adjustment Points and Relationships to Drive COM
Concerning the Adjustment Principle for NORMAL ADJ.
NORMAL ADJ assumes that LCOS panel color irregularity properties are identical from low
brightness to high brightness. For instance, if the upper right of the screen is tinted magenta
(not enough green) at one level, it assumes that the same position is tinted magenta from low
brightness through high brightness.
In the example above, not enough green on the upper right of the screen from low through
high brightness makes it possible to do one color irregularity adjustment for all levels. Color
irregularity adjustment is actually gamma adjustment of each adjustment point on the LCOS
panel. Accordingly, it is possible to extrapolate from panel VT properties how much to
compensate for green at each level from low brightness to high brightness.
In other words, when the compensation value is determined for one level, it is then possible
to obtain the compensation value for other levels.
Electrical Adjustments 1 ―――― Adjustments Using Internal Signals (Gamma Adjustment, Uniformity Adjustment)――――
Changing DRIVE COM : 512→
450 changes BRIGHT LEVEL :
200/255 → 180/255.
However, the adjustment point
does not move, so “output”
does not change in relation to
the various points.

Adjustment Procedures
Gamma Adjustment and Uniformity Adjustment
Using Internal Signals
Concerning NORMAL ADJ. (Continued)
The following illustration shows the relationship between contrast levels and gamma adjustment
values and between contrast levels and output brightness (with γ=2.2). If “brightness” in the
upper right at level x is changed by only A, color irregularity within the screen becomes uniform,
and if brightness in the upper right at level x’ is changed by only A’, then color irregularity within
the screen becomes uniform. In this instance, “contrast level” must be changed by only a and a’ in
the upper right of the screen. Since the relationship between the contrast level and output
brightness has a gamma 2.2 for the relationship between a and a’, the following equation is true.
a' = ((x'/x)^2.2) × a
To change the contrast levels by only a and a’ gamma compensation values of δ and δ'
respectively must be added. Since the gamma compensation value and the color irregularity
compensation value are the same, adding color compensation values of δ and δ' completes
color compensation at the various contrast levels. Thus, if the panel properties are identical from
low through high brightness and gamma adjustment can be performed routinely, color irregularity
compensation results for one level can be applied to other levels. This inter-polation method is
how NORMAL ADJ handles color irregularity adjustment for all levels.

Check macro gamma for each contrast level in single-color green. Look at the entire multi-screen
image, and if there are disparities in brightness between screens, do a color irregularity adjustment to
produce uniformity. (brightness differentials can easily occur between the four corners)
8
Next, display all colors and do a gross color balance adjustment of the reference screen.

If this step fails to yield color balance between screens at a particular contrast level, navigate
COMMON GAMMA ADJ TABLE 0 MACRO GAMMA(5p) to go into gamma adjustment mode
and adjust the color balance of that contrast level.

11
12
Observe the colors at each contrast level in macro gamma, and if there is any color irregularity
between screens in the entire multi-screen image, do a color irregularity adjustment to make it uniform.
If you perform a color irregularity adjustment, do a fine adjustment in macro gamma adjustment.
If this step fails to yield color balance between screens at a particular contrast level, navigate
COMMON GAMMA ADJ TABLE 0 MICRO GAMMA to go into micro gamma adjustment mode,
and adjust the color balance for that contrast level.
【Warning】
Except when the color balance is extremely poor at a particular contrast level, please do
not use micro gamma adjustment mode for color G if there is no special need to do so.
If you must use it, display internal grayscale for each primary color and check to make
sure brightness changes occur smoothly for each contrast level.
Also, if you notice color differences on the black screen, navigate COMMONCOLOR
CONTROLBLACK LEVEL COM. to adjust the value and make the color uniform.

8.1.1. Setup and Mode Numbers
Setup and Setup Data
The projector signal processing circuitry converts input signals into a signal format that
can be input into the LCD panel using a built-in scan converter. Therefore, to display
images correctly, image signal conversion formats have to be stored (setup) in the builtin scan converter. The result of the setup process (setup data) is stored in memory. This
projector is capable of storing multiple sets of setup data to make it compatible with
multiple signal sources and to store settings for expanded displays, etc.
Mode Numbers (Scan Mode Numbers)
Mode numbers (scan mode numbers are used to identify setup data stored in memory.
They are assigned as shown below according to application in the range 0-191. The
projector is shipped with preset setup data for typical signals (S000-S051 in the table).
This preset data is “original data” copied to mode numbers 1-127 for use. Users are not
allowed to overwrite these values.

by the same input terminal.
Setup data is exclusively preset for video input. When the video input
terminal is selected by remote controller or the input switch button it must
be displayed in this mode number.
Various types of signal data are preset. If no user data is stored in the area

different. In this case, it may overwrite adjustment states performed later on. Mode numbers are
assigned for each terminal even if input comes from a different RGB terminal, and so subsequent
adjustments would of course be overwritten.

8.2. External Signal Setup
8.1.1. Setup and Mode Numbers
Setup Using Preset Data
For the projector to setup image signals to be displayed, it needs detailed timing data for
those image signals (resolution, horizontal/vertical sync frequencies, etc.). It is extremely
laborious to collect this data every time a new signal is connected. Accordingly, preset
data is provided to reduce the amount of trouble. The most appropriate data (closest to
the timing of the image signal being connected) can be chosen from the provided preset
data, copied to some part of the user area (modes 1-127) and detailed adjustment
performed on the display position based on this data.
【Warning】
The term “setup” in the explanation below means “the procedure for making adjustments so signals
are correctly displayed, based on the preset data” (as described above).
User Area and Preset Data
Mode numbers 1-127 and 128-191 both are areas available to users. However, as
shipped from the factory, the content of the presets differ for the two. The area 1-127 has
the content of S000 copied in, while 128—178 has the content of S001-051 copied on
(mode no. 128 contains preset S001, 129 S002, and so on).
Accordingly, even when modes 1-127 are not in use (not set up), the projector will
search for setup data that most closely resembles the input signal starting at mode no.

*1 : When doing a setup using mode numbers 1-127, one of the input terminals RGB1, RGB2, and
RGB3 is assigned one-on-one to the mode number. As a result, the projector searches only
mode numbers to which selected input terminals (terminals with signal input) are assigned out
of all the mode numbers that were set up, which expedites processing.
Note that the only searchable input is RGB terminal. Even if the optional video input board is
added, video terminals are not auto-scanned.

To activate auto-scan, navigate MODE ADJ. OTHERS AUTO ON/OFF and set it to “ON.” The
factory default setting is “ON.”

The projector searches for a frequency stored in mode numbers 1-127 that
corresponds to the input, searching with the degree of precision shown below.
During searching, the projector starts with lower mode numbers (frequencies
stored in mode numbers are values stored during “SET UP” and “SYNC PRESET”
during “MODE INITIAL SETUP” adjustment).
H : ±1/100 V : ±1/150 or less

Next, if the search yields no mode that meets the above criteria, the projector
searches again for a frequency stored in mode numbers 1-127, searching with
the degree of precision shown below.
H : ±1/50 V : ±1/75 or less

If the projector cannot find a corresponding mode using Procedures 1 and 2, it
searches starting at mode no. 128 in ascending order. In this area the frequency
range that matches a single mode number is wide, and so signals with different
frequencies are sometimes included in the same range. In this instance, the
same mode number may be selected for different signals.

8.1.3. Concerning Mode Numbers 134-191
Pay close attention to the following if you are doing a setup or adjustment using mode
numbers 134-191.
・ If mode numbers 1-127 are unused, the projector automatically assigns a mode
number from the range 134-191 based on input signal resolution and frequency.

・ If input consists of a VGA/60, SVGA/60, XGA/60, SXGA/6, SXGA+/60, UXGA/60 or
1080i signal, data suitable for display of full-motion video (known as V-LOCK data,
described in detail below) is given priority for assignment .
*1 Terminal RGB3 does not support UXGA resolution.
・ When multiple signals are being adjusted, if the input signal resolution and frequency
is similar, the same mode is assigned. In this instance, the content of signals adjusted
earlier will be overwritten by content written later.
・ Automatically selected mode numbers can refer to signals with different timing. When
mode numbers are automatically selected, these signals cannot be adjusted using the
same mode number. Handle such situations as described below.
(i) If a computer is the signal source, change resolution and refresh rate under
screen property settings on the computer, and make the setting so that the
selected mode has a different number.
(ii) If you cannot make changes to computer settings, either use a mode number
between 1 and 127 for one signal, or reconfigure the projector as an externally
controlled device and use the external control device to designate the mode
number.

1
Connect to the input terminal (RGB1-3) that actually uses the signal being adjusted.
【Warning】
You must make the settings by connecting to an actual signal via an actual pathway (some
type and length of cable). Even if you have to do the setup with a temporary signal source,
please do the setup again a few days later using the actual signal that will be used. Even the
slightest differences will affect the adjustment results, which can produce gaps in the screen
or screen flutter.
Hold down the ADJ key and press the SUB key to go into service person adjustment mode.
3
Navigate MODE INITIAL SETUP SET UP, and there choose from terminal RGB1, RGB2,
or RGB 3. When you make the selection the projector automatically switches the input
terminal and displays the setup data selection menu.
4
Choose one of the following menus based on the type of signal being input and the criteria.
1）
）AUTO SELECT
Choose when connected to a computer. The projector will search for and display the
probable optimal setup data for the current input signal. It will also preferentially assign VLOCK data (setup optimized for full-motion video display) for signals with a refresh rate of
*1
60Hz.
*1 VGA/60Hz、SVGA/60Hz、XGA/60Hz、SXGA/60Hz、SXGA+/60Hz、UXGA/60Hz、
1080i RGB input
2) NTSC x 2
Choose when doing setup for NTSC double speed images (general purpose NTSC line
doubler, etc.).
3) HDU SELECT
*2
Choose when connecting a Hitachi video signal high density scaling device (HDU-600
or other).
*2 The HDU-600 has a scan conversion function to NTSC doubling and computer
signals. It supports not only NTSC input but also 480i, 480p, and 1080i formats.
4) MANUAL SELECT
Use this menu when you cannot get correct display after choosing one of the three
menus above, or when you are doing a setup using different a different preset from the
preset automatically selected.
While referring to the setup data displayed on-screen (see following page), use the keys to choose a preset number (S001-S051) displayed in the “FROM” column. After you
choose one, press the SUB key to move the cursor into the “TO” column.
【Warning】
The projector displays the setup data it retrieved on-screen except when MANUAL
SELECT is used. However, these screen messages are temporary, and if you press
the END key at this point the message terminates and returns to the original screen.
The setup (copying of presets) cannot be executed.

（A）If the horizontal display resolution exceeds 1280 dots
Use preset data for horizontal resolution of 1280 dots or less (referring to the illustration
on the previous page). Images of 1281 dots or greater cannot be displayed. You also
cannot deal with such a situation by changing the value of IMAGE CAPTURE WIDTH to
adjust display width. The only option is to use preset data for more than one resolution.
For example, to do a setup for a display resolution of 1366 X 1024, use presets S033,
S034 and S045 to create a dot matrix of 1400 X 1050. Make adjustments by changing
the sampling clock and the scaling factor.
（B）Handling Full-Motion Video Images (V-LOCK Mode)
Occasions are increasing for displaying full-motion images even when using RGB input.
The preset data includes data described as “V-LOCK,” which contains settings to
enable smooth motion when displaying full-motion video.
In order to use V-LOCK mode preset data, set the RGB signal output device (computer,
etc.) for the following signals. When one of these signals is actually input and AUTO
SELECT is executed, the projector will automatically select V-LOCK mode preset data
preferentially.

Sampling Clock Setting (SAMPLE CLOCK)
(1) Purpose
This adjustment matches the image signal pixel clock with the internal scan converter
sampling clock so that image pixels are correctly sampled.
-
If the total pixel clock number is known, enter that number as-is. Enter a vertical
stripe signal and check to make sure there is a match.
In the case of multiple enlarged screens, etc., set the sampling clock for one screen
and then use that value as-is for the remaining screens.

Hold down the ADJ key and press the SUB key to go into service person adjustment mode.
2
Navigate MODE ADJ. RGB ANALOG INPUT SAMPLE CLOCK to go into
sampling clock adjustment mode.

Use the key to increase the total clock number.
Use the key to decrease the total clock number.
Press the END key to quit.

【Warning】
Sampling adjustment for signals other than LCOS panel resolution (1400 X 1050
dots)
With signals having a resolution other than LCOS panel resolution, repeating vertical
stripes can remain visible after the vertical stripe signal is displayed even when the
sampling matches, because of pixel padding and skipping resulting from pixel
interpolation. If this happens, pay attention to the following and adjust accordingly.
(A) Repeating vertical stripes produced by pixel interpolation do not move even
when the sampling phase is changed.
(B) When the sampling clock is mismatched, the vertical stripes produced by pixel
interpolation overlap with those produced by sampling clock mismatch (see
illustration below).
(C) Sampling can be difficult to assess when SMOOTHING is applied. In this
instance, turn SMOOTHING “OFF” so that each pixel is clearly visible. This will
make it easier to assess.

pattern, which means that sampling deviates by 4 dots, while the bottom row deviates by 2
dots). If the periodicity of the mismatch is hard to determine, check the sampling phase

Changing the sampling
phase moves the stripes.
(B) Use the following method to determine if the sampling clock is correct or not.
When the value of the sampling phase (SAMPLE PHASE) is increased:
- Stripes shift right : sampling clock is too high
- Stripes shift left : sampling clock is too low
If the signal source sampling clock number is clear, set the sampling clock value to that
value as-is.
※ The sampling clock number is the total horizontal dot number, NOT the number of
horizontal display dots.
Displaying the Stripe Signal
In sampling clock adjustment, if it is possible to display the “vertical stripe” image with
the stripes separated by 1 dot or 2 dots, then it is possible to ascertain the clock
deviation from the cycle count between stripes (density variation occurs between
ranges where sampling is matched and mismatched).
On Windows OS based computers (Windows 98, Me, Windows 2000) choosing “Shut
Down” in the Start menu makes the screen turn black. In this state the entire screen
turns into a tiny checkerboard pattern. This signal can be used instead of the stripe
signal if needed.
8
Electrical Adjustments 2 ―――― Adjustments for External Signals (Setup)――――
When the sampling clocks are mismatched, shifting the sampling phase moves the
vertical stripes in the areas where sampling is matched and mismatched. The more
vertical stripes there are, the more the sampling clocks are mismatched (sampling
clocks mismatched by the width of the vertical stripes – 5 dots in the above
illustration). When the sampling phases are matched, the entire screen is matched
and mismatched.

Scaling Factor Setting (SCALING) and Position
Adjustment (POSITION)
(1) Purpose
After doing the setup for input signals, enter settings for the scaling factor and the area to be
scaled when displayed on all pixels on the LCOS panel and when displaying enlarged
screens. Also enter smoothing settings so the pixels do not look jagged with scaled images.
After you complete the scaling factor settings, do a position adjustment to align the signal with
the appropriate position.
(2) Explanation
Scaling factor settings will be explained through example.

Perform compensating adjustment for black depth to counter the effects of lighting
and other ambient light.
(2) Signal-Specific Color Balance Adjustment
【Warning】
When color balance is still poor or there are significant color irregularities between the screens even
after the adjustment in this section, take another look at “9.1.3 Uniformity and Color Balance
(Gamma) Adjustment Using Internal Signals.”
Color Adjustment in the AD Converter Input Unit (Applied Only with Analog RGB
Input)
- Adjustment Using a Marker
Adjustment to correct for deviation in the signal-specific input level is handled via
the AD converter in the input unit on the main board.
Input from an external signal source an image in which black (minimum level) and
white (maximum level) are displayed. The “marker” in this adjustment matches the
black portion with internal signal “0/255” (actually “1/255”) and the white portion
with “240/255” (when 240/255MARKER is selected), thereby turning the black
portion white and the white portion black.
【Warning】
This adjustment presumes that CLAMP POS. adjustment is complete. If a clamp error occurs, black
adjustment will be erroneous.
8
Electrical Adjustments 2 ―――― Adjustments for External Signals (Setup)――――
(A) Basic color balance adjustment for this projector uses an internal all white signal, as
described in “9.1.3 Uniformity and Color Balance (Gamma) Adjustment Using
Internal Signals.”
However, the image output level for analog external signals varies significantly, and
so the color balance can vary from that of internal signals when an external signal
white is displayed. This variance can be adjusted so that external and internal
signals have the same color. Use the method described in “(A) Color Adjustment in
the AD Converter Input Unit.”
(B) If you want to make signal-specific changes in the brightness level and tone (color
warmth), after performing “(A) Color Adjustment in the AD Converter Input Unit,” you
can change the brightness and color warmth for each mode number in “(B)
Brightness and Color Adjustment Using the Gamma Table” (DRIVE adjustment,
BLACK LEVEL adjustment).
(C) If you want to change the gamma curve itself for a particular signal, in scan mode
adjustment mode navigate MODE ADJ. COLOR GAMMA TABLE NO. and
specify either gamma table no. 1 or 2. Your specified gamma table will be applied to
that scan mode. (Normally gamma table “0” is specified for all scan modes.)

The granular appearance of the inverted portion of the display is due to noise in the
external signal. Adjust in the place where the inverted white region area is greatest.
This adjustment will match internal signal 240/255 with the white portion of the image
signal (normally 0.7V). The range 241-255 is the white portion excess. It can be
adjusted to a range where it will not be saturated even if the image signal is changed
to 0.75V.
If you want to make this adjustment without using the marker, press the MARKER key to
turn it off. Then press the key again to turn it back on.
Use when you want to adjust the “254/255 MARKER” so the input signal amplitude is
right at the maximum permissible level. However, if the image amplitude increases
because of temporal change, bright areas will be saturated.

【Reference】
You cannot set a value lower than the state for black (internal signal 0/255) after
completing “Color Adjustment in the AD Converter Input Unit.”
【Warning】
When you use “DRIVE” and “BLACK LEVEL” to change the brightness level and color
tone in a multi-screen configuration of 2 screens or more, first perform this adjustment on
the scan mode of one screen that you will use as a reference screen to adjust the
brightness and color balance, then adjust “DRIVE” and “BLACK LEVEL” to the same

PFD Gain Setting Method
PFD gain adjusts the PLL circuit pull-in gain used by the A/D converter for image
sampling.
If gain is too low it causes jitter (oscillating thin vertical lines).
If gain is too high, then with composite sync signals and SYNC ON GREEN signals there
can be curvature in the upper part of the screen.
If these phenomena occur, perform adjustments to lessen them.
Electrical Adjustments 2 ―――― Adjustments for External Signals (Setup)――――
Clock frequency example : 64kHz (horizontal frequency) X 1,688 (sampling clock
no.) = 108MHz
Make sure to read off the on-screen value of “SAMPLE CLOCK” after you adjust the
sampling clock accurately.
If the clock frequency is outside the range of VCO settings in setup mode, then make the
needed adjustment.

8.1.12. Auto-scan Settings
(1) Automatic Switching Settings
This section offers an example of settings for the auto-scan automatic switching function.
Special Example Using a PC, Etc., Controller
In this example, 4 types of signal timings are set up in mode numbers 17-20 on the image
display computer. The RS232C telecommunications port on the PC communications control
device (referred to below as system controller) is used to send the mode number. Please
refer to Chapter 9 for a discussion of RS-232C control.
Procedure
1
Adjust the signals from the image display computer onto mode numbers 17-20.
The horizontal scan frequency and vertical scan frequency at the time the input frequencies are
written to memory (either at SETUP time or when CLEAR is pressed twice in "SYNC SET") are
saved as the frequencies for that scan mode. When data from mode numbers with similar
frequencies is copied for use, make sure to carry out the input frequency memory save operation
("SYNC SET") for the copy destination mode number.

-
When you perform repair service, make sure to record the date, your name and
organizational affiliation, and the unit and lamp operating time. Only record other data
when some change has been made. (Blank space indicates no change.)
Record values displayed on-screen as-is, without modification.
When you replace a lamp, record the operating time of the lamp replaced.
After replacing a lamp, reset the lamp operating time to zero.
Projectors with automatic lamp changers decide that lamp replacement is incomplete if the
operating time is not cleared. Then they will not do automatic lamp replacements with the lamp
changer even when a lamp malfunctions.
The procedure is as follows: Navigate LOG DATA – LAMP1 TIME or LAMP2 TIME
and press the CLEAR key twice. When operating time is reset to “0,” the “LAMPx

(2) Control multiple projectors using RS485 communication
(3) Control multiple projectors using RS232C communication
An explanation of each method follows below.
9.1.1. Control a single projector using RS232C
communication
For this method, connect one projector to the communication port (RS232C
communication pin) on a PC to control it. You can control power On/Off or input pin
switching. See “9.4 Communication Commands” for more information.

[Note]
The only device whose operation was confirmed using the RS485 converter is the “TRS-T”
made by Data Link Co., Ltd. With other converters, the logic level in communication
becomes unstable and stable communication control might not be possible.

Projector System Setup and Control
*3 : You must set termination by turning ON as a binate the termination of the RS485 converter side and
the last device (Projector D in the above connection example) in a daisy chain connection. If you do
not set termination correctly, control operation will become unstable.
*4 : Stabilize the logic level in communication. If it is “OFF”, a communication error (such as a framing
error) will occur on the projector side and control operation will become unstable.

Projector Control
Control multiple projectors using RS232C
communication
By performing RS232C communication with one projector, the signal is converted into an
RS485 signal and transferred to other projectors. In the previous subsection 9.1.2 RS485
communication, an RS232CRS485 converter is externally set up, but the projector itself
performs the conversion processing.

During broadcast communication, (BSN) is bit0 for Projector Nos. 0, 32 and 64 for
example, so these numbers cannot be distinguished. In RS485 communication where
projectors are daisy chained together, you must be sure these projectors do not exist
on the same line.

(3) Communication rules
・ Timeout results if byte-byte transfer interval exceeds approximately 6ms.
・ Maximum command reply time is 5 sec., except during projector adjustment. During
adjustment, reply time may exceed 10 sec. because the save operation to the
memory is in progress.
・ The Projector No. is the communication ID that is set for each projector. You can
change the setting as explained below.
(A) While pressing the ADJ key on the remote control, press the SUB key to display the menu.
(B) Move the menu cursor using the or key and select items using the key. Select in the
order [SETTINGS] → [PROJECTOR NO.].
(C) You can set a value from 0 to 255 using the and keys, but “255” does not function as the
ID because all projects will respond in this case.

9.4. Communication Commands
(1) (00H) : Power ON/OFF request
(A) Description
(i) This command requests a lamp to be activated or deactivated.
(ii) A projector immediately replies when receiving a command. The actual lamp
activation process is performed after replying to ACK.
(iii) Even when replying to ACK, the lamp might not activate if there is a projector
fault. Use the Status (20H) command to confirm your understanding of this state.
(iv) When not specifying a lamp, performs the activation process on the lamp that
was activated during the activation process for the previous lamp.
(v) If the inactive information is ON for both lamps, performs the activation process
on LAMP1. When specifying the activated lamp, replies to ACK and performs the
activation process on LAMP1.
(vi) Performs the lamp activation process even if the inactive information for the
specified lamp is ON. If the lamp did not activate, lamp switching is automatically
performed and the lamp activation process is performed on the other lamp.
However, the read request (1EH) for the lamp inactive information flag must
check the lamp and the Power ON request must not be performed on the inactive
lamp.

Communication Commands
(2) (02H) : Display color ON/OFF request
(A) Description
(i)
This command is set when screen distortion is visible after switching the input
signal or when simultaneously performing screen blanking on multiple screens
in the Multiscreen mode.
(ii) Approximately 4 sec after executing screen blanking (at least one color is OFF),
forcibly cancels screen blanking. However, the time required for cancelling
screen blanking might increase if a synchronization signal fluctuates or
becomes unstable during screen blanking.
(iii) NAK replies when the power is OFF.
(iv) If there is no signal for the input frequency after the screen blanking request,
cancels screen blanking approximately 3 sec later and displays “NO SIGNAL”.
Also, if the input frequency is not supported, displays “OUT OF RANGE”.
(v) In addition to the previous command formats, this command supports command
formats that set the forced cancellation time of screen blanking. This makes it
possible to prevent a projector from cancelling blanking on its own when the
image switcher, etc needs 3 sec or longer to switch the input.
(vi) If a projector is executing processes such as mode switching on its own, screen
blanking might not be performed within the specified cancellation time.
Incidentally, the target for mode switching is approximately 2 sec, but more time
might be required if the synchronization signal is unstable.
(vii) The interval for displaying “NO SIGNAL” or “OUT OF RANGE” increases along
with the increased cancellation time setting.

(A) Description
(i) This command controls brightness from the operation panel. Brightness settings
decrease the brightness.
(ii) Once set, brightness data is valid unless the power is OFF (the lamp is
deactivated) or there is a transition to the Adjustment state (for both repair
personnel and regular users). Switching the scan mode does not return the
setting to the previous values.
(iii) This command is even accepted when the power is OFF. However, turning the
main power OFF clears the settings.
(iv) Settings made during lamp cooling are accepted, but might not take effect
depending on the timing. This command makes settings after lamp cooling ends.
(v) When decreasing brightness, the brightness-color balance change might vary
slightly depending on the individual variation between projectors.
(vi) When setting brightness data, the screen becomes brighter momentarily then
dims to the set brightness.

Communication Commands
(5) (1EH) : Lamp Not Lit Information flag read request
(A) Description
(i) If the lamp did not light, burned out, or was forcibly deactivated because of the
cumulative lamp running time, this information is for the bit corresponding to the
failed lamp that the projector turned ON. When this flag is ON, it indicates an unlit
lamp and the changer does not change the unlit lamp.
(ii) To clear this flag, either clear the cumulative lamp running time on the
Adjustment screen or write “0” using a write request for the following Lamp Not
Lit information flag. Only changing the lamp with a normal lamp does not clear
this flag.

(A) Description
(i) This command switches the mode data by specifying the mode number (see
Chapter 8). The mode data stores the adjustment data (color balance or screen
zoom information) that was set by a separate remote control.
(ii) After data expansion ends, this command automatically cancels blanking.
However, this command does not cancel blanking performed using the display
color ON/OFF setting command (02H).
(iii) Is only valid when the AV controller is not connected and NAK replies when it is
connected. When controlling even though the AV controller is connected, the AV
controller ID code is 1FH.
(iv) NAK replies when performing adjustments.
(v) Executes Auto Scan () from the specified scan mode when “AUTO ON/OFF” of the
specified mode is set to “ON”. (Does not search areas newer than the specified scan
mode.)
(vi) For auto scan, the input pins to be searched are the input pins that the specified
scan mode sets. Switches to the specified scan mode when the VIDEO input pins
are set.
(vii) For auto scan, does not measure the frequency approximately 100 ms after the
command (25H) is received. Therefore, to switch the video signal, you must control
the switching so it ends within 100 ms.

Projector System Setup and Control
(A) Description
(i)
This command replies when the lamp switch request is accepted.
(ii) Projectors perform the lamp activation process (Retry when necessary) required for
lamp switching, overlap activation, and changer switching.
(iii) If lamp switching could not be executed because of the lamp not activating or a
changer malfunction,
(a) When there is overlap activation, lamps that were lit prior to the request remain lit.
This allows you to use the screen without it going out.
(b) When there is no overlap activation, lamps that were lit prior to the request
deactivate, so the projector performs the lamp activation process again.
(iv) After the lamp switching request, the target time until lamp changing is actually
executed is
(a) Approximately 2 minutes later when there is overlap activation (set from the menu
screen). However, if the lamp is not lit when Retries occur, switching will be
delayed approximately 20 sec for each Retry. Lamp switching will therefore be
delayed by the time required for Retries (up to 5 times).
(b) Switching is executed immediately when there is no overlap activation. This
command performs the lamp activation process after lamp switching.
(v) This command replies when receiving a request. The projectors perform all remaining
processes. This command checks whether lamp changing was actually completed
using Status Reply (20H) and the Lamp Unlit Information flag read request (1EH)
command.
(vi) When the request for switching to Lamp 1 or Lamp 2 matches the currenly lit lamps
and changing the lamps is unnecessary, this command only ACK replies.
(vii) When a projector sets no overlap activation, the projector replies after performing the
Power OFF process.
(viii) Overlap Activation ON/OFF is performed using the Adjustments menu with the remote
control
[SETTINGS] → [LAMP SETTING] → [WARM-UP ON/OFF]
(ix) When externally controlling alternating activation, the alternating activation function
the projector performs itself is set to “OFF”. Adjustments menu using a remote control:
[SETTINGS] → [LAMP SETTING] → [AUTO CHANGE SEL.]

LCOS
Specifications
・ ”Super Smooth Picture” results in seamless high-detail
image reproduction with no feeling of graininess.
・ The “High Speed Liquid Crystal” display produces
crisp full-motion video with no residual images. The
system is equipped with new high-speed drive circuitry
with full-motion high-speed response time of 16.7
msec or less (TV signal).
・ The “Pure Color LCOS 3chip” methodology splits the
three primary colors (R, G, and B) between three
panel layers, resulting in clear and true color
reproduction. Clear colors and a wide reproduction
range yield expression very close to the real object.
・ The “HITACHI Super Drive Engine LCOS” features a
high contrast ratio of 1300:1, along with high
brightness of 100cd/m2 and a wide120O left-to-right
field of vision.
* : Model 50 1000cd/m2, Model 70 500cd/m2. System
can be set up anywhere, even in bright rooms.
・ “High Quality Lens” means high image resolution in a
compact space just 55cm* deep, making the unit
easier to transport and making it feel less oppressive.
* Model 50 ES50-116CM (space compared to older
Hitachi models: 93%)
・ High light-resistant UV materials and rear surface
cooling fan technology extends system service life.
The LCOS will bring you consistently beautiful images
with no color changes. And because it has no
polarizing plate, it costs less than half to operate than
older models.

LCOS Multi-Screen Model Cabling Diagram
(3) Fig. (a) : Attach Connector Name Labels to Connectors, Fan ASSY
Press the label on firmly when attaching, and watch out for peeling.
Connectors [DD], [VB], [SS], [IV], and [VX] already have labels, so do not put labels
on them.
・ Connector ([HD], [VS], [IH] cable)
Because there are so many terminals,
only put labels on clusters (5-7
strands).
・ Connector ([F4] cable)
Attach the connector label on the right
hand side of the connector as shown.
・ Fan ASS ([F1], [F2], [F3], [F5])
Attach the connector label to the
indicated location of the fan ASS.
(i) Cut the connector ([VX] cable) and strip the
ends.

(5) Procedure 1 : Preliminary Cabling Inside the Set (Circuit Board Block Diagram)
(A) Backup Cabling to PSA-LCOS-CON
・ Attach the cabling as shown to
the right. (Attach [F*] on the PH
connector side. Attach [F8] on the
PH2p side. [VS], [AA], [F3], [F5],
[EH], [PA], [F2], and [F8] can be
attached later.)
・ Attach PH3p short connector to
[F4].
・ Attach the EH3p short connector
made in Fig. (b) to [VX].
【Specification】
- This illustration shows the view from the front of the unit.
- Some of the cable destinations in the illustration overlap, so pay close attention in
cabling to the symbols on both ends of the connectors and to the pathway
symbols.

Cable Connection Diagrams
(B) Cabling for PSA-LCOS-MAIN, PSA-LCOS-CON, PSA-LCOS-SW, Circuit Power Unit
・ Connect [SS], [EF], [FF], and [DF]
to PSA-LCOS-MAIN. When
inserting [SS] into the MAIN
board attachment, insert it until
you hear a definite click.
・ Make sure when attaching [F1]
that slack cabling does not come
into contact with the fan blades.

(C) Cabling the POW-P5XMLA CIRCUIT P Unit
・ Make sure to cable [EH], [PA],
and [F8] so they do not come in
contact with the power primary
side even when the force of 10N
is appled. Install the cabling so
there is no excess length at this
connection. Excess length
should be brought over the
power extraction section.
【Specification】
- This illustration shows the view
from the front of the unit.
- Some of the cable
destinations in the illustration
overlap, so pay close attention
in cabling to the symbols on
both ends of the connectors
and to the pathway symbols.

[F2] is installed between the top
cover and the top cover
hardware. Install it so it does
not come in contact with the
power primary side even when
the force of 10N is applied.
Excess length should be placed
around the cabinet wiring
fasteners shown in the lower
portion of the illustration.

(6) Procedure 2 : Overall Assembly Cabling (Drive Board Unit, Whole)
(A) Cabling the PSA-LCOS-DRIVE Unit ([SS], [VS], [F3], [F5] connections)
・ Insert [SS] until you hear a definite clicking sound.
・ Attach an SM connector to the rear portion in order to cable [F3] and [F5].
(B) Cabling the PSA-LCOS-REM Unit ([AA] connection)
・ Install the cabling through the cabinet wiring fastener*2 behind the lens, from the
side toward the bottom. Excess length should be placed around the bottom side
lead clamper.
(C) Cabling the LAMP CHANGER ASSY Unit
・ Cable [HD], [IH], and [VB] connections as shown below.
If the cable protrudes laterally it will contact the rear panel during 6-axis
adjustment. Accordingly, make sure to secure the cable with bead ties so it
does not protrude to the side (cut leaving 5 beads extra).
【Specification】
- This illustration shows the view from the front of the unit.
- Some of the cable destinations in the illustration overlap, so pay close attention in
cabling to the symbols on both ends of the connectors and to the pathway
symbols.

E. Theoretical Principles
1. LCD Panel Display
The illustration below shows the LCD panel pixel matrix, consisting of 1024 horizontal dots
and 768 vertical dots. This makes it possible to perfectly match the input signal pixel pitch
for a signal with a resolution of 1024x768 dots (referred to hereafter as XGA) with the LCD
panel matrix.
In addition, the scan converter built into the projector can adjust the pixel count to enable
the LCD panel to display signals with a resolution of other than XGA, signals that cannot be
displayed 1-to-1 signal pixel to LCD panel pixel.

E. Theoretical Principles
2. Sampling Clock And Sampling Phase Adjustment
The analog RGB video signal input from cable BNC is entirely digitized by the built-in scan
converter. When the analog signal input from BNC is converted to digital form, the image is
subjected to sampling. But if the settings for this sampling process are incorrect, the projector
cannot realize full display performance. The sampling process is described below.
(1) Sampling phase misalignment occurs because of misalignment between the video signal
and the delay time in the processing circuitry and the cabling. Readjustment is needed if
there is a change in the PC or EWS, or a change in the cabling or switch connection
pathway. If this adjustment is incorrect, the signal level can fluctuate at the vertical edge,
and vertical line contrast may not be accurately reproduced.
(2) The sampling clock is generated by multiplying the input horizontal sync signal in the PLL
circuit. This multiplier has to be aligned with the total number of horizontal dots in the input
signal, including blanking. If this frequency is out of alignment, there appear on the screen
areas in which the sampling phase is correctly aligned and those in which it is completely
misaligned, in periodically alternating patterns, as shown in Fig. (c). (If it is misaligned by 1
dot, the left half of the screen is aligned but the right half is misaligned, or vice versa.)

Sampling Phase Adjustment.”
User adjustments are described under ”H SIZE” and “SAMPLE PHASE,” respectively.
