PRECAUTIONS FOR USE AND MAINTENANCE
Request to User
Screen protector
Screen protectors are provided to protect the screen from scratching and separation
during transportation.
Please remove screen protectors before using the projection unit and attach them
when storing or transporting the projection unit.
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 video wall 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 cases, wait
for a while (with keeping power ON) until the condensation clears.
About radiator fan
The radiator fan in the projection unit needs to be replaced after about three years of use. Contact your
dealer for the replacement work.
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 cloth. Since the screen surface is
easily scratched, do not rub it with a hard object. Never use a chemical duster.
Care of the cabinet

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.

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, WB3) before making adjustments.
There are two stages for white balance adjustment to allow adjustment of low-level and
high-level portions of the image.
For low-level adjustment 10-20% IRE signal is required and this should be provided by the
main source to be used (i.e. if video is the main source a video test pattern generator should be
used and if computer is the main source test pattern software should be used).
BRIGHTNESS will control the overall brightness of the image (not available for DIGITAL
input) and CUTOFF followed by ADJ.R, ADJ.G and ADJ.B can be used to adjust the relative
intensities of red, green and blue.
For high-level adjustment 70-80-90% IRE signal is required.
CONTRAST will control the overall level of the image (not available for DIGITAL input) 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 Off-Set
The above adjustments act on the digital signal (after the A/D converter) and assume a signal
level of 0.7V p-p.
It is also possible to adjust the analogue signal (before the A/D converter) but these

Electronic Circuit Explanation
1. RGB/Control PCB
Input signals RGB1 and RGB2 are switched by analogue RGB switch IC, ADG774.
VIDEO input is decoded by VPC3230D, auto-switching between PAL and NTSC, the
output is 16 bit 4:2:2 YUV.
DIGITAL signal is supplied to SII151, single link DVI receiver.
Analogue signals are then converted to digital by A-D converter is AD9884.
The digital signal is supplied to the frequency converter scaler PW164.
The functions of PW164 scaler IC are:
- Auto-detect 48-bit RGB signal display timing
- Auto-adjust capture, position, signal clock and phase
- Auto-capture video 16 bit YUV signal
- Image scaling up/down (VGA, SVGA, SXGA to XGA)
- Frame rate conversion with frame buffer memory
- Video YUV 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
Incoming signals are all converted to XGA, 60Hz
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 rotation speed is 120Hz.
The output from the scaler is supplied to the magnification scaler, GmZ4S and this IC is
controlled by MCU8051.

ELECTRIC CIRCUIT EXPLANATION
2. DMD Driver PCB
The processed digital signal is sent from the RGB/Control PCB to the DMD Driver PCB via
the 96-pin digital signal cable. The TI driver IC controls to signal supplied to the DMD
through frame memory buffers.
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 resulting power factor
is 1.
The output of the PFC circuit is 370V DC and this is supplied to the main and standby
DC-DC converters and also the Lamp Ballast.
The outputs of the main DC-DC converter are +12V and +4V, the outputs of the standby
DC-DC converter are +12V and +5V.
Over-voltage protection is triggered when the +4V supply rises above +6.3V. SCR201 is
controlled by ZD201 and this triggers the protection circuit.
Short circuit protection of the +12V and +4V lines is monitored by IC101 pin3 and the +12V
and +5V standby lines are monitored by IC104 pin5
4.Lamp Ballast PCB
The Philips® 120W UHP lamp is driven by Philips ballast power supply, input voltage is
370V DC and high voltage trigger and lamp supplies are output.
5.RS232C Control PCB
RS232C control signals and remote control from optional CT90000 are accepted, if both are
connected CT90000 has priority.
6.Video PCB
Accepts PAL/NTSC composite video signal and has a buffered output for loop-through.
