NOTE TO SERVICE
PERSONNEL
UV-RADIATION PRECAUTION
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 sun-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 BQC-
XVZ90+++1 rated 370V/150W.
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 below and handle the lamp with care.

Lamp
Reflector
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.
Note: Please obtain a lens cap before servicing a
models XV-Z90E/XV-Z91E that is received
without one.
DANGER ! –– Never turn the power on without the
lamp to avoid electric-shock or damage of the
devices since the stabilizer generates high voltages
at its start.
UV-RADIATION PRECAUTION (Continued)
Lamp Replacement
Note:
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

Precautions for using lead-free solder
1 Employing lead-free solder
"Front-R/C, LED, Terminal1, Terminal 2,Rear-R/C and key PWBs" 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:
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.
3 Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead solder
by 40°C, and as it has poor solder wettabillty, you may be apt to keep the soldering bit in contact with the PWB for
extended period of time. However, Since the land may be peeled off or the maximum heat-resistance temperature
of parts may be excoeded, remove the bit from the PWB as soon as you conurm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to tum on
and off the power of the bit as required.
if a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after
every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Becareful when replacing parts with polarity indication on the PWB silk.
LFa
Indicates lead-free solder of tin, silver and copper.

* 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.

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.

Function
Light source. DC-driven high-pressure mercury vapor lamp.
Used to absorb ultraviolet and infrared rays.
Used to let the source light through the color filter and to
separate it into R, G and B colors.
Used to make for uniform light beams.
Used to collect the light from the rod lens into the DMD
chip.
Used to reflect the light from the relay lenses against the
DMD chip.
Used to introduce the light from the reflector over the effec-
tive surface of the DMD chip. When the micromirror gets
tilted (ON) as specified, the reflected light is guided to the
projection lens.
Used to turn on and off the micromirror in response to the
ratio of color components at each dot and thus to reflect the
incoming light accordingly.
Used to enlarge the light from the DMD chip and to get the
light projected on the screen.

Caution when repairing without top cabinet
To repair this set without top cabinet, attach the left side body beforehand. (Since the exhaust heat gets in around the
set and the temperature sensor detects it giving the TEMP error and the lamp goes off.)

•There are two types of warning lights: a TEMPERATURE
WARNING indicator that warns you when the projector
is too hot, and a LAMP REPLACEMENT indicator that
warns you when to change the lamp.
•If a problem occurs, either the TEMPERATURE WARN-

Condition
The internal tempera-
ture is abnormally high.
The lamp does not light
up.
The lamp requires re-
placement.
Problem
• Blocked air intake.
• Clogged ventilative hole.
• Cooling fan breakdown.
• Internal circuit failure.
• Burnt-out lamp.
• Lamp circuit failure.
• Lamp has been used for over
2,400 hours.
Possible Solution
• Relocate the projector to an area with proper ventila-
tion.
• Clean the ventilative holes.
• Take the projector to your nearest Authorized
SharpVision Service Center or Dealer for repair.
• Carefully replace the lamp.
• Take the projector to your nearest Authorized
SharpVision Service Center or Dealer for repair.
•If the TEMPERATURE WARNING indicator lights up, follow the above possible solutions and then wait until the
projector has cooled down completely before turning the power back on. (At least 5 minutes.)
•If the power is turned off and then turned on again, for example during a brief rest, the may be triggered,
preventing the power from going on. Should this occur, unplug the power cord from the wall outlet and plug it
back in again.
