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.

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.

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.

Power Supply PCB

3.

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.

Video PCB

6.

Accepts PAL/NTSC composite video signal and has a buffered output for loop-through.
