Precautions in replacing the DMD chip
Note: Be careful not to allow dust and
fingerprint on the cover glass of DMD
chip and prism surface of optical
engine.
1. When you fix 4screws of backer
plate assembly, press backer plate to
formatter PWB and fix by cross-
multiply step by step.
2. If something shade appears on the
projection screen like Fig1, release 2
screws on mirror adjusting plate and
move that plate to adjust illumination
area of DMD chip.

* Precautions in setting up the DMD (Digital Micromirror Device) unit
Before connecting the formatter PWB to the optical engine, take the following steps. Look at
the voltage rank marking that is on the DMD itself. Referring to this marking set the DIP
switches on the formatter PWB. And connect this PWB to the optical engine. Wrong settings
will adversely affect the system performance.

Many electrical and mechanical parts in Projector have special safety-related characteristics.
These characteristics are often not evident from visual inspection, nor can protection afforded
by them be necessarily increased by using replacement components rated for higher voltage,
wattage, etc.
Replacement parts which have these special safety characteristics are identified in the

service manual; electrical components having such features are identified by 

 and

shaded areas in the Replacement Parts Lists and Schematic Diagrams. For continued
protection, replacement parts must be identical to those used in the original circuit. The use of
a substitute replacement parts which do not have the same safety characteristics as the
factory recommended replacement parts shown in the service manual, may create shock, fire
or other hazards.

The light source, metal halide lamp, in the projector emits small amounts of UV-
Radiation.
AVOID DIRECT EYE AND SKIN EXPOSURE.
To ensure safety please adhere to the following:
1. Be sure to wear UV protective glasses when servicing the projector
with the lamp turned “on” and the top enclosure removed.

2. Do not operate the lamp outside of the lamp housing.

3. Do not operate for more than 2 hours with the enclosure
removed.

UV-Radiation and Medium Pressure
Lamp Precautions
1. Be sure to disconnect the AC plug when replacing the lamp.
2. Allow one hour for the unit to cool down before servicing.
3. Replace only with same type lamp. Type BQCPGM20X//1 rated 85V/210W.
4. The lamp emits small amounts of UV-Radiation, avoid direct-eye contact.
5. The medium pressure lamp involves a risk of explosion. Be sure to follow installation
instructions described in the Lamp Replacement Procedure and handle the lamp with care.

Since the lamp reaches a very high temperature during units operation replacement of the
lamp should be done at least one hour after the power has been turned off. (To allow the
lamp to cool off.)
Installing the new lamp, make sure not to touch the lamp (bulb) replace the lamp by holding
its reflector 2.
[Use original replacement only.]

DANGER! –– 

Never turn the power on without the lamp to avoid electric-shock or damage

of the devices since the stabiliser generates high voltages at its start.

Since small amounts of UV-Radiation are emitted from an opening between the duct cover
and the lamp housing, it is recommended to place the LENS CAP on the opening during
servicing to avoid eye and skin exposure.

1 Employing lead-free solder 
"Input, Output, R/C Receiver, Key and Fan PWB" of this model employs lead-free solder. The
LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The
alphabetical character following LF shows the type of lead-free solder.

Example: 

 Indicates lead-free solder of tin, silver and copper.

2 Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder.
Repairing with conventional lead wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by
40°C, we recommend you to use a dedicated soldering bit, if you are not familiar with how to
obtain lead-free wire solder or soldening bit, contact our service station or service ranch in
your area.
