3.1 Precautions

This section describes cautions before starting disassembling and
assembling this product. Make sure to read the precautions below before
starting.

3.1.1 General Cautions in operation

General cautions for disassembling and assembling this product are
provided below. Cautions for each procedure are provided in its
corresponding section. Make sure to refer to them before starting.

 Do not touch the lamp or the parts around it. They are extremely hot

even after the cooling down operation completed. If any maintenance
work inside the projector is necessary soon after the projector is in
operation, leave the unit until it becomes cool enough before performing
maintenance work.

 Never use the air blowers such as a lens cleaner that contains flammable

gas in repair/maintenance work.

 Do not disassemble any components not as specified in this Service

Manual.

 The Optical Engine, the circuit boards are very sensitive to static

electricity; therefore, be sure to take appropriate measures to prevent
static destruction such as to place them inside static-proof bags once they
have been removed from the projector.

 The Optical Engine is very sensitive to vibration and shocks; therefore,

make sure to handle it with care.

 The speaker unit contains a permanent magnet; therefore, make sure to

keep it away from any storage media such as floppy disks or magnetic
cards.

 Be careful not to drop a metal part such as a screw, a washer, or a clip

into the inside of the product. If such cases should occur accidentally,
never turn on the power supply until all the dropped parts are found and
removed.

 When carrying out any of the following operations, check that there is no

dust or dirt on any component or on any glass surface before installation.
If any contamination is found, clean it off using isopropyl alcohol.

Optical Engine removal
Lamp removal

 When the projector is disassembled, the dust in and around parts (such

as those on the fans or air filter) may get transferred to other parts such
as the R, G and B light valves which are the central part of the display
mechanism. This may have an adverse effect on the quality of projected
images. Be sure to check whether any of the parts are dusty or dirty, and
use a vacuum cleaner to clean them first before carrying out disassembly/
reassembly work.

 After reassembling the product, check the following before turning the

power on. All the parts and screws are installed and secured to the
proper positions. No cables are caught in the metal frames.

 For this projector, a calibration is performed for the “Screen Fit”

function at the factory shipment. If the “MA Board (Assy)” or later in the
flowchart is disassembled for repair, the adjusted values may be
misaligned; therefore, restart the projector and check for abnormalities

in the functionality or the projected image.

 The information such as the time of first boot, and the

time of lamp replacement for this machine is recorded
in the memory on the MA Board. The user may need
this information for the purpose of operation and
management of this machine; therefore, when the
"RTC Board" or the "MA Board ASSY" needs to be
replaced, check whether this information is readable. If
yes, read it using the "IPS Tool (Resume)" program
(dedicated program for services and support), and
write it back onto the machine after completing
repairs.
