Proper service and repair is important to the safe, reliable operation of all Philips Consumer Electronics Company** Equipment. The
service procedures recommended by Philips and described in this service manual are effective methods of performing service
operations. Some of these service operations require the use of tools specially designed for the purpose. The special tools should be
used when and as recommended.
It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully read in order to minimize the
risk of personal injury to service personnel. The possibility exists that improper service methods may damage the equipment. It also is
important to understand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Philips could not possibly know, evaluate and
advise the service trade of all conceivable ways in which service might be done or of the possible hazardous consequences of each way.
Consequently, Philips has not undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which
is not recommended by Philips must first satisfy himself thoroughly that neither his safety nor the safe operation of the equipment will be
jeopardized by the service method selected.
**Hereafter throughout this manual, Philips Consumer Electronics Company will be referred to as Philips.

3.Warnings & Notes
Warnings
1.
Safety regulations require that the unit should be returned in
its original condition and that components identical to the
original components are used. The safety components are
indicated by the symbol
!
.
2.ESD1
All ICs and many other semiconductors are sensitive to
electrostatic discharges (ESD). Careless handling during
repair can drastically shorten the life. Make sure that during
repair you are connected by a pulse band with resistance to
the same potential as the earth of the unit. Keep components
and tools also at this same potential.
3.When repairing a unit, always connect it to the mains voltage
via an isolating transformer.
The lamp supply and the lamp housing are not mains isolated.
4.Be careful when taking measurements in the high-voltage
section.
5.Never replace modules or other components while the unit is
switched on.
6.When making settings, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a circuit
becoming unstable.

Notes
UV-RADIATION PRECAUTION
The light source, metal halide lamp, in the LCD 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 ith 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.
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 exposurem (Fig. 1).
Note: Please obtain a lens cap before servicing a model that is
received without one.
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 LCA3110.
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 Replacement
Note: Since the lamp reaches a very high temperature during units
operation replacement of the lamp should be done at l east
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 it reflector
[Use original replacement only].
Cautions Concerning the Setup of the Projector
For minimal servicing and to
maintain high image quality,
PHILIPS recommends that this
projector be installed in an area
free from humidity, dust and
cigarette smoke. If the projector
is used in these environments,
the lens and filter will need to be
cleaned (or the filter replaced)
more often, and internal
cleaning may become
necessary. As long as the
projector is regularly cleaned,
use in these environments will
not reduce the overall operation
life of the unit. Internal cleaning
should only be performed by a
Philips Authorised LCD
Projector Service Centre.
Notes on Operation
•
The exhaust vent, the lamp cage cover and adjacent areas
may be extremely hot during projector operation. To prevent
injury, do not touch these areas until they have sufficiently cooled.
•
Allow at least 10 cm of space between the cooling fan
(exhaust vent) and the nearest wall or obstruction.
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.
•
If the cooling fan becomes obstructed, a protection device will
automatically turn off the projector lamp. This does not indicate
a malfunction. Remove the projector power cord from the wall
outlet and wait at least 10 minutes. Then turn on the power by
plugging the power cord back in. This will return the projector to
the normal operating condition.
