WARNING
This service information is designed for experienced repair technicians only and is not designed for use by the general public.
It dose not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service a product.
Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service
or repair the product or products dealt with in this service information by anyone else could result in serious injury or death.
WARNING : Use UV Radiation eye and skin protection during servicing
If using of this projector at high altitudes (above 1,200m),“Fan Control” to “ON1” or “ON2”.
(Refer to “Setting menu” in Operating Instructions.)
Failure to observe this may cause malfunctions. Never use this projector at an altitude of 2,700m or higher.
Using this projector at high altitude, consult your dealer or Authorized Service Center about preparations.
This projector is using the P.C.Board which applies lead free solder.
Use lead free solder in servicing from the standpoint of antipollution for the global environment.
Notes:
・Lead free solder: Sn-Ag-Cu (tin, silver and copper) has a higher melting point (approx. 217°C) than standard solder. Typically the melting point
・is 30~40 °C higher. When servicing, use a high temperature soldering iron with temperature limitation function and set it to 370 ± 10 °C.
・Be precautious about lead free solder. Sn-Ag-Cu (tin, silver and copper) will tend to splash when heated too high (approx. 600°C or higher).
・Use lead free solder for the P.C.Board (specified on it as “PbF”) which uses lead free solder. (When you unavoidably use lead solder, use lead
・solder after removing lead free solder. Or be sure to heat the lead free solder until it melts completely, before applying lead solder.)

Maintenance
Cleaning
Cleaning the projection window
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning cloth.
When the cabinet is heavily soiled, use a small amount of
mild detergent and finish with a soft dry cleaning cloth. Avoid
using an excessive amount of cleaner. Abrasive cleaners,
solvents, or other harsh chemicals might scratch the surface
of the cabinet.
When the projector is not in use, put the projector in an appropriate
carrying case to protect it from dust and scratches.
Cleaning the projector cabinet
Cleaning the color wheel
- The color wheel is made of thin glass. Be very careful
when handing the color wheel.
- In case of fingerprints, etc. on the surface, gently
wipe
with a Cleaning Cloth for optical parts that contains a
small amount of non-abrasive camera lens cleaner to
clean the surface.
- Do not use detergents as this could cause peeling of
the color filter.
Unplug the AC power cord before cleaning.
First, remove the dust with a commercially available air blower.
Then gently wipe the projection window surface. Use a
cleaning paper moistened with methyl alcohol (methanol).
Avoid using an excessive amount of cleaner.
Do not use abrasive cleaners, solvents, or other harsh
chemical cleaners to avoid damaging the projection window.
After long periods of use, dust and other particles will accumulate on the optical parts, mirror, color wheel, lens
etc.,causing the picture to darken or color to blur. If this occurs, remove dust and other particles using air spray.
Beforetaking the cleaning, turn off the projector and allow the projector to cool for more than 60 minutes. Never
disassemblethe optical unit, mirror or projection lens because those parts are aligned preciously in the factory . If
do so,the projector may have the miss-alignment in optical and reduce the optical performance.
Cleaning the reflecting mirror
- Be careful not to touch the reflecting mirror. Touching
it directly with the hands may cause reducing the
burnishing.
- Do not clean other than with air.
Caution
The optical components may have a crack or spot when
you use the air spray directly to the optical components
while they are in the state of hot. Use a commercial
(inert gas) air spray designed for cleaning camera and
computer equipment. Use a resin-based nozzle only. Be
very careful not to damage optical parts with the nozzle
tip.
CAUTION
Do not use any flammable solvents or air sprays on the projector
and in its vicinity. The explosion or fire hazard mayoccur even after
the AC power cord is unplugged because the temperature inside
the projector is extremely high due to the lamps. In addition, there is
a risk that the internal parts may be damaged not only by the flam-
mable air spray but also by the cold air.
