SAFETY PRECAUTION

WARNING: Service should not be attempted by anyone unfamiliar with the necessary precautions on this
projector. The following are the necessary precautions to be observed before servicing this chassis.

1. An isolation Transformer should be connected in the power line between the projector and the AC line
before any service is performed on the projector.

2. When replacing a chassis in the cabinet, always be certain that all the protective devices are put back in
place, such as; non-metallic control knobs, insulating covers, shields, isolation resistor-capacitor network
etc.

3. Before returning the set to the customer, always perform an AC leakage current check on the exposed
metallic parts of the cabinet, such as terminals, screwheads, metal overlays, control shafts etc. to be sure
the set is safe to operate without danger of electrical shock. Plug the AC line cord directly into a AC outlet
(do not use a line isolation transformer during this check). Use an AC voltmeter having 5000-ohm per volt
or more sensitivity in the following manner: Connect a 1500-ohm 10W resistor, paralleled by a 0.15-MFD,
AC type capacitor, between a known good earth ground (water pipe, conduit, etc.) and the
exposed metallic parts, one at a time. Measure the AC
voltage across the combination of 1500-ohm resistor
and 0.15-MFD capacitor. Reverse the AC plug at the
AC outlet and repeat AC voltage measurements for
each exposed metallic part. Voltage measured must
not exceed 5.25V(rms). This corresponds to

3.5mA(AC). Any value exceeding this limit constitutes
a potential shock hazard and must be corrected
immediately.

PRECAUTIONS FOR USE AND MAINTENANCE

Request to User

Plastic Screen

The P503DL screen is made of a plastic material and can be easily scratched. During manufacture and
packing, every care is taken to ensure that no hard objects that could scratch or otherwise cause damage are
allowed to touch the screen when opening the carton box and taking out the product. Please exercise
caution, when unpacking the unit to prevent the packing material or other items from scratching and
rubbing the screen to avoid (i) damage to the screen and (ii) generation of static electricity which may attract
dust particles onto the screen.

Precautions on Use

Connection of a grounded cable

Ground the projection unit in order to prevent electric shock with 3-core power cable. There is greater danger
of electric shock when multi projection units are used without ground wire connected.

Condensation

When room temperature rises rapidly (or the Dat a Display projection unit is moved from a cold place to a
hot place), condensation may form on the lens, causing picture distortion or color fade-out. In such case, wait
for a while (with keeping power ON) until the condensation clears.

About cooling fan and color wheel motor

The axial cooling fan and also color wheel motor in the projection unit should be considered a consumable
item and need to be replaced after about one or two years of use or whenever noise or other symptoms of
breakdown are apparent. Contact your dealer for the replacement work.

** Air filter equipped at air intake needs periodical cleaning. A clogged air filter will result in temperature

build up inside the P503DL cabinet. Possibly in excess of stated operating specification, th is may lead to

malfunction or reduced equipment life.

Maintenance

Do not use solvent or paint thinner
If these are used, coating layer may peel off or deteriorate. If rubber or plastic comes into contact with the
projection unit for a long time, the projection unit may be stained.

Care of the screen

After switching the power supply off, gently wipe the screen with a soft cotton cloth. Since the screen
surface is easily scratched, this may also build up an electronic static charge. Do not rub it with a hard
object; the screen may be easily damaged. Never use a chemical duster.

Care of the cabinet

After switching the power supply off, wipe gently with soft cloth.
When using a chemical duster, follow the maker's precautions.

Care of the air filter

The air intake filter should be regarded as a consumable and changed on periodic bases, depending on the
operating conditions. If or when the filter becomes clogged (by oily smoke etc) replacement of the filter is
recommended.
For a temporally remedy, the filter may be cleaned by an oil removal cleaner, detergent used in a kitchen
or a diluted vinegar solution.

ACCEPTABLE RGB INPUT SIGNAL TIMING

Following are acceptable RGB input signal timings which have been tested by Toshiba. These are timings
checked on the RGB input terminals of projection unit. If signal supplied is not exactly the same as one of
the followings but is simile to one, it may be accepted by adjustment of projection unit.
When picture caused horizontal jitter or display position difference, adjust the projection unit with optional
controller. However, when signal cable used or other factors have problems, timing may cause trouble and
picture will not be stable. When signal is not stable, each function of projection unit will not be guaranteed
for good picture display.

for a multi-projection system using four
projection units.
In this example, signal sources are
supplied from composite video signal to
video-card and signal from a PC is
connected to each cubes by signal links.

The optional wired remote controller is
connected to Unit-1 and all the units
could be controlled by the remote
control through System Bus-Link when
RS232C communication links are daisy
chain connected.
The final RS232C output should not
return to 1st cube.

When both, RS232C control signal and
CT-90000 wired remote control are
connected, the remote control has a
priority over PC, RS-232C connection
thus PC control is not possible.

This is an example of 4 sets attached together by 2x2 configuration. When 4 sets are combined together
with the screws fastened, a gap between cubes becomes small and also stable for entire wall.

The internal locking screws need to be fastened while front screen has removed, carefully watching
frame of each cubes. Do not tighten the screws very strong, aluminum frame may be deformed by
such strong fastenings.

To do this, remove one of the screw, make loose for
another and rotate the plate then fasten to adjacent
cubes together.

8) Upper portion Pin-cushion adjustment
This adjustment is to bent the mirror and make the adjustment, do not over do it.
This adjustment is easy to do while cube is not assembled to wall but even assembled, it is possible
to perform removing the screen of the cube, attached on it.

Important Notice:

Do not exceed the adjustment too much, when mechanism comes to an end of its adjustment area,
there is no stopper mechanism provided and further forcing to do so will make fatal damage to the
mechanism.

These mechanical adjustments are important to display all the light coming out from engine to
the full screen. If this mechanism adjustment is not good, picture may not appear in full screen
however by electronic position and capture may possible to display.

Still, the 1st adjustment to obtain the full image is not an electronics but mechanism.

After performing all the mechanical adjustments, then electronic adjustment could be started.

Here is the summary of the adjustments.

1. Mechanical position adjustment by internal or external flat-field picture. Before this adjustment,
it is better to reset all the electronic position adjustments at the center/reset value.

2. Electronic Picture Position adjustment by external signal, there may be a little differences between
internal and external signal positions so that the signal which is generated from the PC which will
be used, is the best to supply.

3. After the position adjustments, then, color balance adjustment would be performed.
DMD drive condition can be changed by “Cutoff” and “Drive”. These adjustments could be
Done by internal test signal.

Then, “Offset” and “Gain” are provided to compensate the difference of signal level from PC.

3. Electronics Adjustment or Setting
Selection or adjustment can be performed using optional Remote Control, model CT-90000 or no

Ob ligation, user-risk freeware, “Cube Commander”.
Not all keys are used for adjustment.

Connect the remote control to the REMOTE jack (3.5mm stereo jack) on the projector.

This remote control is compatible for most of Toshiba data -wall display cube.
The GUI of cube commander is also similar layout of the push buttons so that once the position of
these key pads are getting familiar, both can be used without any difficulty.
Difference between this remote control and software is, the ID number access, this is caused by the

ADJUSTMENT

3-1. Input Signal selectio n

Sources are selected by pressing the relevant source button: RGB1 RGB2 or VIDEO.
To select and display video picture, the video input adaptor need to be installed.

The screen will mute for approximately 5-7 seconds following source selection.
Source sele ction is basically possible in Normal Mode.

27

3-2. Adjust Mode

Press ADJUST to enter Adjust Mode.
To exit Adjust Mode press ADJUST twice (one press will request confirmation that
you wish to exit Adjust Mode).

3-3. Saving adjustments

Adjusted value will be memorized into its non -volatile memory when WRITE button is clicked.
In case if the new adjustment value is not acceptable, simply shut off the power by rocker switch
so that this new adjusted value will be erased and go back to “before adjustment” value.

3-4. Adjustment parameters

All parameters except ‘Layout’ can be adjusted using the ? ? ? ? buttons.
‘Layout’ position is adjusted using the ´ ` < > buttons.

3-5. Internal Test Pattern

Test Patterns can be accessed by pressing TEST.P in Adjust Mode.
Continuously pressing TEST.P button will cycle through the available patterns or individual
patterns can be selected by entering the relevant two digits number as 0 7 TEST.P for direct
number access for test signal #7.

3-6. White Balance adjustment

There are three independent memories for white balance adjustments, press WB in NORMAL mode
to select the desired memory (WB1, WB2 or WB3) before making adjustments.

There are two stages for white balance or color balance adjustment to allow adjustment of
low-signal-level and high-signal-level portions of the image.

For low-signal level adjustment, 10-20% IRE signal is required and this should be provided by
the signal source to be used (i.e. if video is the source, a video test pattern generator should be
used and if computer is the main source, test pattern generating software should be used).

BRIGHTNESS will control the overall brightness of the image and CUTOFF then followed by
ADJ.R, ADJ.G and ADJ.B can be used to adjust the relative intensities of red, green and

blue.
For high-signal level adjustment, around 70-80 -90% IRE signal is required.

CONTRAST will control the overall level of the image and DRIVE followed by ADJ.R, ADJ.G and
ADJ.B can be used to adjust the relative intensities of red, green and blue.

3-7. Gain and Offset

The previous adjustments as cutoff, drive, contrast or brightness act on the digital signal
(after the A/D converter) and assume a signal level of 0.7V p -p was supplied.
It is also possible to adjust the analogue signal (before the A/D converter) but these
adjustments should be kept to the default values in most cases of connecting one PC.
While DVI connection is used, this adjustment is not available.

ADJUSTMENT

In case if the display is connected to multiple output card or such equipment having several
individual outputs as video-wall processor, offset/gain adjustments w ill be the right an basic
adjustment to compensate each signal level difference from each outputs.

OFFSET then following by ADJ.R, ADJ.G and ADJ.B can be used for the low-signal-level

adjustment and GAIN , then ADJ.R , ADJ.G and ADJ.B for the high-level adjustment.
Adjustment hint: Cutoff and Drive adjustments can be done using internal test signal.

28

Display flat field test signal and press “cutoff” or “drive”, then adjustment is possible.
In case of “offset” and “Gain” adjustments are placed at early signal process area and internal test
signal is generated later stage than this adjustment, thus flat field test signal needs to generate
from PC. Thus PC needs to have such signal generation software installed.

These color balance adjustments need to repeat several times from low signal level,
Then perform high signal level, again, returning back to low, then high level signal.
Repeat them several times to achieve better color balance.

This is the general idea of adjustments:
DVI input: only “Cutoff” and “Drive” by internal test signal or from PC
RGB1 or RGB2, one PC: “Cutoff” “Drive” by internal test signal or signal from PC and then, also

“Offset” “Gain” by signal from PC for sub-adjustment
RGB1 or RGB2 using video-wall processor: “Cutoff” “Drive” by internal test signal and “Offset”

“Gain” by the test signal comes from PC
In this case, Offset and Gain adjustments are much more important to
perform.

Video input: “Cutoff” “Drive” by internal test signal and possibly “Brightness” and
“Contrast” if needed by the signal from source

3-8. Clock frequency adjustment and phase adjustment

Supply fine pitch signal (such as Windows shut -down screen) and adjust CLOCK and PHASE
to eliminate moiré an d jitter.

3-9. Image position adjustment

Initial image position should be adjusted using the mechanical adjustments with internal test picture
while electronic positions are at center so that all the unmagnified images appear at the same
position. Use POSI to electronically shift the image and CAP to select the position of the image for
magnification.

3-10. Screen Mode (frequency) Selection

Incoming signals are automatically synchronized and the relevant timing data is stored in memory so that
this data can be read out each time a particular source is recognized. RGB1 and RGB2 settings are
memorized separately. There are total of 10 signal memory areas available, additional frequencies differ
from VESA standard, they will be memorized for next time synchronization.

3-11. On-Screen-Display, OSD
The default condition is for the OSD to be on, this can be switched off by pressing the CALL button in
Adjust Mode.

ADJUSTMENT

It is possible to change the color of the OSD:

SPECIAL A = red, SPECIAL B = green, SPECIAL C = blue, SPECIAL 8 = white.

3-12. Video Enhancer

When video input is selected, the following adjustments are available: COLOR , TINT (NTSC only)
and SHARP

3-13. Picture in Picture

This is a feature which opens a small window and insert video image. The video signal input
Terminal adaptor need to place. The PC image is the base and small window has video signal

Image, they cannot be changed. Get into Special mode by SPECIAL and 7 buttons will guide
to this feature. PIP picture position can be changed by arrow keys.

3-14. Image Orientation

The image orientation can be flipped up, down, left and right using the FLIP key.

3-15. Status Indication

Pressing CALL in Normal Mode will display general information such as input selection and source
frequency.
Pressing SPECIAL and then D in Adjust Mode will display software version and date.

SPECIAL F will display the lamp timer and SPECIA L E will display lamp history.

3-16. Factory reset STD key

This key need to be careful since all the adjustment data will be reset if pushed.
There is an on-screen-display indicating if this function would be performed or not.
Pressing this button again will erase all the adjustments and data are reset.

3-17. Color Mix adjustment (Color coordinate Control)
This is to compensate the color difference for example, when red picture is displayed on multiple
screens and reds are different as pure red vs orange red. An ideal condition is to have all the same
pure red all over the screens but in case if orange-red appeared at once cube, then other cube can be
color compensated to add some greens so that other red can be matched to the orange-red so that all
the colors can be matched same. Opposite operation, making orange to red is impossible.

Use 7 button while in Adjust mode, then click 4 for Red primary color and select ADJ.G for
the color to be mixed in case of above situation. The prima ry color would be 5 for Green, 6 for Blue
and ADJ.R , ADJ.G or ADJ.B will select the color to be mixed.

4. Multiple Screen Wall system (example)
The picture shows 2x2 wall by one PC displaying picture,
using internal magnification capability.
To make this image by internal signal processor, MAG
need to be set to 2x2 and left top cube need to have
Layout of 1 -1. The cube at right bottom needs to have
Layout of 2 -2. Small position adjustment may be needed
to match the picture. When using internal magnification
capability, still, all the cubes need to receive the same signal
and DVI digital link will cover this part, using DVI cables.
When cube need to control or any adjustment needed, then each cube need to have its ID #
different from the others so that the command can be sent to the right ID # cube.
This picture effect (ex. 2x2) can be memorized as User Magnification Pattern (p -36).

ADJUSTMENT

5. ID Assignment (example)
IDs should be assigned before connecting the RS232C control link cables and if ID has assigned
already and want to change, it must be cleared at first befo re they can be re-assigned.

5-1. Clearing I.D.

Press ADJUST to enter Adjust Mode and then press ID.ALL to enter I.D. Mode, press ID.SEL
3 times and then press ID.CLR to erase the current I.D.

5-2. Setting I.D.

Press ID.ALL so that ‘INPUT ID NUMBER’ appears and enter the desired 2 digits I.D. using the
alpha-numeric keys. Press ID.SEL 3 times and then ID.SET to assign the I.D. – the OSD will
disappear and the unit will return to Normal Mode.

30

5-3 Selecting I.D.

If using Cube Commander software simply select the two digits I.D. for the cube you wish to control.
If using remote control it is necessary to press ID.SEL to access the correct menu for I.D. selection
and control.
If ID.ALL is pressed instead of an alpha-numeric key ‘X’ will appear, pressing ID.ALL twice will
display ‘XX’ (two wild cards) which will allow to control of all units simultaneously.

6. Magnification
To magnify the image, press MAG in Adjust Mode to change the magnification factor then type H+V
magnification numbers as needed such as 1x1, 2x2… It is also possible to select the magnification
factor for uneven magnification as 4x3 for example, horizontal of x4 and vertical of x3 magnification.
To make this magnification effective, MAG needs to be clicked again.

Once the desired magnification has been selected press LAYOUT followed by ´ ` < > to select
the portion of the image to be displayed. If the picture will not match at the mullion area, then

POSI. will cover the adjustment. Then, to memorize this picture, press WRITE .

7. Function in Special mode

7-1. Auto-Adjust On-Off
This is to select if automatic centering function, of frequency converter, necessary or not.
Auto center may have a chance to shift the image when power is completely down and on again.

7-2. Picture in Picture
By using 7 key after entering Special mode, Picture in Picture is possible. Always, the base picture
is PC signal supplied to RGB input and small window picture is the signal supplied to Video input,

composite signal.

7-3. OSD color
On screen display color can be changed by 8 : wh ite, A : red, B : green or C : blue in

Special mode.

7-4. Power On delay

By the setting of small power on timing to avoid the same time of lamp trigger, power supply can
be set from 0-sec to 4.5-sec. This delay time is not accurate since the lamp may not ignite by the
1st trigger all the time. Entering SPECIAL mode, then click 9 makes to change the Delay time.

7-5. Firmware version

Using D button in Special mode, the system Firm-ware version could be displayed.

ADJUSTMENT

7-6. Lamp Timer History
By E button, Lamp usage timer history could be displayed.

7-7. Current Lamp Timer indication
This mode will display only one lamp display, the current lamp. When lamp timer needs to reset,
Entering to this mode will conduct to the further operation.

7-8. Lamp Timer Reset
While in Special mode, F will indicate the current lamp timer and using STD button twice,
then WRITE button, the current timer count will stop and starts from new counter reading.

8. Function in Service mode

8-1. OSD Mute
This is similar as like as CALL button clicked while in Adjust mode, OSD would be erased or

displayed on the screen by 1 button while in Service mode. Even when OSD is erased, still the

31

function is continue to operate as in the same operation mode. One of the good way to use this
operation is, in normal condition, OSD appears when Input is selected in Normal mode. Some user
may not like this, then enter this mode or other method is, enter Adjust mode, then click CALL so
that OSD will disappear even in the system is in Adjust mode. Then click WRITE button to
memorize this function.

8-2. Screen mode Lock
This could be used only when one designated PC used, so that the same PC picture will appear always

correct but not for the other PC. Use 2 button while in Service mode
8-3. Picture smoothing filter

This is applying smoothing filtering on picture, by using 4 button, selection can be done.

Electronic Circuit Explanation

1. Input/Output/Control PCB

RGB Input signals are switched inside of AD converter and then level controlled by Offset and
Gain, in AD9888, then fed to AD converter section of the same IC.
VIDEO input is decoded by VPC3230D, auto -switching between PAL and NTSC, the output is
supplied by 8:4:4, 16 bit digital YUV signal to PW166 frequency converter scaler (scale up/down).
DIGITAL signal is supplied to SII161, single link DVI receiver then fed to PW166.
Supplied signal to PW166 is changed to 1024x768, 60Hz and then be supplied to next stage.
Switched digital signal is supplied to SII160 to form DVI output.

The functions of PW166 scaler (scale up/down) IC are:

- Auto -detect RGB signal display timing

- Auto-adjust capture, position, signal clock and phase

- Auto -capture NTSC/PAL video signal

- Image scaling up/down (VGA, SVGA, XGA, SXGA to XGA , 60Hz)

- Frame rate conversion with frame buffer memory

- Video RGB color space conversion

- Test pattern OSD generation

- On-chip 16 bit MPU for software development

- DMD control signal Generation

- Digital 24-bit RGB, XGA outputs

-

ELECTRIC CIRCUIT EXPLANATION

Incoming signals are all converted to XVGA, 60Hz except PAL signal (50Hz).
Signal recognition and scaling is carried out using standard VESA signals, if a non-standard signal is
supplied, the image may not be displayed correctly.
All incoming signals are converted to 60Hz and the color filter wheel rotation speed is 120Hz.
The output from the scaler is supplied to GmZ4S magnification IC and then, sent to DMD drive board.

2. DMD Driver PCB
The processed digital signal is sent from the RGB/Control PCB to the DMD Driver PCB via multiple
pins connector (50-pin & 30-pin) together with all the necessary signal and also power supply.
The TI driver IC, DDP1000 controls the signal, supplies to the DMD through frame memory buffers,
also color wheel motor signal is sent to M307982APZ.

The DMD element, TI Driver DDP1000 and DAD1000 form DDR chip set, a Texas Instruments
products.
Signal send out timing from TI driver to DMD is programmed to suit Toshiba filter wheel which is
based on good color reproduction even having white portion for so called “non-flicker” ignition.

32

The lamp used is UHP 100/120W, driven by the ballast, this lamp/ballast combination is made by
Philips enables to select lamp power for 100W or 120W by mechanical slide switch.
Do not replace the lamp with other model, a reflector which focuses the lamp beam is designed for
DLP use, with light tunnel application. Different lamp may not have right specification or lamp life
may be much different. The lamp for previous model, P500DL, is different from the P503DL lamp.
To avoid such confusion, the lamp connector has different shape so that other lamp will not fit.

3. Power Supply PCB

The power supply consists of two sections, Power Factor Control and DC-DC conversion.
Incoming AC is rectified and supplied to the PFC converter, where the voltage and current phases are
matched, thus resulting power factor becomes 1.
The output of the PFC circuit is 380V DC and this is supplied to the main DC-DC converters and also
the Lamp Ballast.
The outputs of the main DC-DC converter are +12V, +6V and +4.5V.
Also, +12V which is connected to the fans and +5V for micro processor are separately prepared.

4. Lamp Ballast PCB

The Philips® 100/120W UHP lamp is driven by Philips ballast, power supply. The input voltage is
380V DC and high voltage trigger which is about 20kV pulse to i gnite while lamp start period and
lamp supply voltage is given to continue to its discharge by about AC50V, plus non-flicker pulse drive
voltage is superimposed from lamp ballast output.

5. RS232C Control PCB

RS232C control signal or/and remote control from optional CT90000 are accepted, if both are
connected CT90000 has priority over RS232C communication line.
RS232C parallel cables need to use.

6. Video PCB (option)

Accepts PAL/NTSC/SECAM composite video signal and has a buffered output for loop-through.
Normally in case of PC picture, DVI internal link would be used for not so much active movement
pictures but in case of video picture, sometimes, DVI link may contain some picture frames of delay
occurred by each cubes so that images of all the cubes may not match but later the connection,

more movement delays may result.
In such occasion, Video output to next video input, video loop through may results better picture

by less delay composed.

Note: DVI signal Link output
is converted to XGA/60 signal

Note:

1. RS232C is connected to PW166B Scaler

2. Lamp ballast is using reduced flicker ignition system, use specified lamp listed in the parts list

Note: When color balance adjustment is necessary, this is a small hint to perform.

1. Use internal test signal so that flat field is displayed to all the displays.

2. Offset/Gain cannot be performed since these adjustments are located before the test signal generator
section.

3. Supply low signal level about 10 or 20% amplitude and adjust “CUTOFF” of each displays and obtain
the same white balance.

4. Supply high level signal about 70-80-90% whichever suite to the occasion.
Adjust “DRIVE” so that all the displays have the same white balance.

5. Repeat Cutoff/Drive adjustments several times since each adjustments affect each other.

6. When a magnification/picture-insertion signal processor is used, connect each output wire to each
display.

7. Adjust “OFFSET/GAIN” so that all the colors/white balances are the same. This is to compensate
the difference of output signal level of each input, do not touch or readjust Cutoff/Drive, these

Trouble shooting hints

1. When lamp does not light

a. Lamp will turn on but shut-off by itself within a short period of time

This is one of the symptom when the lamp becomes to its life end. Intensity becomes low, lamp
gap becomes wide, thus ballast power supply voltage becomes not enough to sustain the charge.
the lamp needs to replace.

b. Lamp bursts

This is another phenomenon when lamp comes to its life end. The internal pressure becomes
high and lamp breaks, lamp will not turn on, this is clearly the end of lamp life.

c. Lamp will not turn on

This is also another style of its end of life. When the gap between electrodes became wide, even high
voltage ignition will not start the lamp discharge. This is another possibility. In this case, if carefully
observed, lamp ballast will make noise while start ignition trigger is supplied, if this sound can be hear,
then ballast is most possibly OK and lamp is wrong.

2. W hen lamp does not turn on

a. There are several possibility even the lamp is new. When one of the Fan stop its rotation, the motor

sensor stop sending signal and CPU will turn of the lamp power to avoid heat going up by no airflow
inside.

b. When Color wheel motor is stopped, then motor rotation signal becomes missing, then this change also

sends to stop lamp power.

c. Lamp door open, this condition also shut off the lamp power.

3. When color becomes strange

a. Electronic circuit break down will lead for such color differ ence, key components are DMD drive

board and I/O control board. 1st trial may be exchange the Control board to try out.

b. At the time when color wheel motor may not synchronize to the incoming signal, there is a possibility to

have different color or color flicker happens. If motor makes noise, then this is most possibly motor
bearing needs oil. If motor becomes difficult to have smooth rotation, the color changes sometimes and
comes back, then repeat this color change. The motor replace needed most possibly.

4. When picture is strange and totally distorted

a. There may be a possibility that some strong noise entered and micro -processor jammed. One of the

easiest way is to shut off rear rocker power switch and wait for some period of time as one minute, then
turn it on. By waiting such time, micro-processor will totally reset and possibly restart without any
difficulty. This is caused by CPU jam by noise.

b. When some difficulty happened on reset or original program start at DMD drive circuit, the picture may

not be right or also I/O control board. Try replacing these boards one by one.

5. When color wheel motor needs to replace

a. When color becomes different or will not synchronize, color wheel motor may oil or replace.
b. It may be better to remove optical engine. Then follow as below pictures show.

(1) (2)

c. When mounting the color wheel motor, take care not to touch the round glass color filter which has

Note: When Lamp door switch is tripped, power supply will shut off and lamp turns off, this is not a trouble,

sharp edge, there may be a risk of hand/finger hurt. Also oil f rom finger attached on the filter may
be burn during operation by lamp heat and color or brightness may not right or possible damage of filter.

this is normal operation. Before replacing the lamp, it is recommended to turn off the rocker switch
and shut off power. The door switch is provided to prevent accidental touch while lamp is ON. Still,
the lamp may be hot after door switch activated, it is better to turn off the main power switch and wait
for some period of time as several minutes until lamp becomes safe temperature.
