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
AC VOLTMETER 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
0.15MFD
3.5mA(AC). Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately.
Good earth ground such as a water pipe, conduit, etc.

Place this probe on each exposed metallic part.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics are often passed unnoticed by a visual inspection and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc.
Replacement parts which have these special safety characteristics are identified in this manual and its supplements; electrical components having such features are identified by the international hazard symbols on the schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement parts which do not have the same safety characteristics as specified in the parts list may create shock, fire or other hazards.

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.

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 adjustments should be kept to the default values in most cases.
OFFSET followed by ADJ.R, ADJ.G and ADJ.B can be used for the low-level adjustment and
GAIN followed by ADJ.R, ADJ.G and ADJ.B for the high-level adjustment.
27

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.
