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 Data 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 fanand 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, this 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.

DVI connector and RS232C cables are included as accessories. RS232C cable is common type and if

cubes are assembled more than 10 sets, RS232C communication error may become obvious by means of

its standard, length limitation. In such case, using better and thicker wire may extend the cable length

or possibly use buffered splitter and separate the wiring into two or more branch will result better

communication.

DVI output signal is possible to make link for any selected input but this DVI output comes after its

frequency converted digital output, having several frames of signal delay. Thus quick movement

such as moving video may result signal delay added by each cubes and picture may not match while

moving image displayed.

The specifications and design of this product are subject to change without notice.

Note: Maximum length of the RS232C cable in total length is about 20-30 meters.

If the length becomes much more than its specification, the communication error may occur.

When some miss-reading of commands start to occur, then use better quality wire than its standard

may reduce trouble and possible to extend the communication wire length.

Using RS232C signal buffer distributor and separate the cable connection into two or more will also

Reduce miss-communication troubles.

With this model DVI output is possible to form signal link connection by daisy-chain connection of

DVI cables. When this feature is used, several frames of signal delay will occur by each cube’s

electronic circuit so that when moving picture is supplied, picture junction may not match.

When the set is opened from its carton box, 1^stthing to do is to

ADJUSTMENT

(1) Locate the screw at the lens barrel to adjust focus

(2) Rotate thumb screw to counter clockwise, then move the screw head to and fro to rotate so that

lens focus can be adjusted.

(3) Tighten the same screw to clockwise to fix the adjustment.

(4) Engine mount adjustment preparation

(5) Before doing Engine Mount mechanical adjustment, it is better to adjust an electronic position

adjustment at the center.

Use remote control or Cube adjustment software and enter Adjust mode, then perform H-V position

adjustment, then place at the center of the range so that electronically, it is at the center.

2. ENGINE MOUNT ADJUSTMENT

1) Use internal test signal, TEST.P #07, thus full frame cross-hatch image appears on the screen

2) Left to Right Trapezoid adjustments can be performed by rotating (H) screw.

By doing this Adjustment, horizontal position will move but disregard its movement of position.

Obtain parallel image at top and bottom, then re-adjust position after this trapezoid adjustment.

When top/bottom parallel adjustment is done, tighten (J) screw.

test signal will appear for 6 pixels thickness in the image.

Do not adjust this if mechanism comes to an end, further adjustment will damage the mechanism.

(F)

ADJUSTMENT

Above adjustments will do positioning and also sizing. The position could be compensated by the

electronic adjustment but the size needs to be done mechanically. It is better to make mechanical

adjustment as much as possible so that any different magnification, the image will appear right.

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 1 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.

Electronics Adjustment or Setting

Selection or adjustment can be performed using optional Remote Control, model CT-90000 or no

Obligation,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

command generation CPU, in a PC which the software is installed or use the CPU in the cube.

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

number access for test signal #7.

TEST.P for direct

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 usedto 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 will 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.

Download from Www.Somanuals.com. All Manuals Search And Download.

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 and 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

Download from Www.Somanuals.com. All Manuals Search And Download.

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 thatall

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 primary 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.

Download from Www.Somanuals.com. All Manuals Search And Download.

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 : white, 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

1^sttrigger 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

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 softwaredevelopment

- 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.

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 ignite 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 fromoptional 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:

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 ofoutput signal level of each input, do not touch or readjust Cutoff/Drive, these

adjustments are done in previous stage.

8. When RGB signal distribution amplifier/buffer is used and each signals are connected to each

displays, follow the same way to adjust the Cutoff and Drive by one signal source and compensate by

Offset/Gain for each signal level differences.

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. When 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 difference, key components are DMD drive

board and I/O control board. 1 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.

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

sharp edge, there may be a risk of hand/finger hurt. Also oil from 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.

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

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.
