SAFETY INSTRUCTIONS
SAFETY PRECAUTION
WARNING: Service should not be attempted by anyone unfamiliar with the necessary precautions on this receiver. The following
are the necessary precautions to be observed before servicing this chassis.
1. An isolation transformer should be connected in the power line between the receiver and the AC line before any service is
performed on the receiver.
2. When replacing a chassis in the cabinet, always be certain that all the prospective devices are put back in place, such as;
non-metallic control knobs, insulating covers, shields, isolation resistor-capacitor network etc.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics are
often passed unnoticed by a visual inspection and the protection afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety charac-
teristics are identified in this manual and its supplements; electrical components having such features are identified by the
international hazard symbols on the schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement
parts which do not have the same safety character istics as specified in the parts list may create shock, fire, or other hazards.

LAMP UNIT REPLACEMENT
Cautions when replacing LAMP UNIT (E998Z; PJ-D95-LMP)
The light source for this TV is a mercury lamp with internal atmospheric
pressure that increases during use. The lamp has a limited service life
that varies depending on user settings. If you use the lamp beyond its
.
service life:
you may notice a reduction in the colors and/or brightness of the pic-
. ture; and
the strength of the quartz glass in the lamp will be reduced and the
lamp may rupture (often making a loud noise when this happens). If
the lamp reputres, the TV will not operate until the lamp unit is replaced.
Note: The lamp unit is designed so broken lamp glass remains se-
curely inside the lamp unit.
CAUTION: Always handle the lamp unit with care.
The lamp unit in this TV was designed for safe replace-
ment by consumers; however, if the lamp unit is subjected to inten-
tional abuse (such as excessive mechanical abuse or handling by
children or pets), the unit may break, exposing edges or pinch points.
When to replace the lamp unit
.
You should replace the lamp unit:
. if the picture darkens and/or colors fade;
. if the lamp does not light; or
If you hear a loud noise and the picture goes black, which may indi-
cate a lamp rupture (LED indication #8). See LED indications on
page 6.
Note: Be sure wear the gloves before replacing the lamp unit.
-8-
1. Turn off the TV and unplug the power cord. 5. Grasp the lamp unit handle and gently pull the lamp unit
straight out of the TV. Set the old lamp unit aside.
2. STOP! Allow the lamp to cool for at least one (1) hour
before replacing it.
6. Carefully insert the new lamp unit straight into the TV
until it is fully seated.
3. On the back of the TV, loosen the thumb screw (by hand)
on the lamp unit door, and then remove the lamp unit
door.
Note :
Never subject the lamp unit to excessive shock.
Never touch the lamp unit glass or otherwise get it
dirty.
Doing so may affect the image quality and reduce
the service life of the lamp. See "Cleaning the lamp
unit glass" below.
7. Using a manual screwdriver, tighten two lamp unit
screws.
Note:Hand-tighten only. Do not use an electric screw-

8. Reattach the lamp unit door, making sure to insert the
hook on the left side of the lamp unit door inside the
opening in the TV cabinet.
9. Replace the thumb screw and hand-tighten.
10. Plug in the power cord and turn on the TV. After the
initial warmup period (which may take up to 45 seconds
for full picture brightness), the TV should operate nor-
mally. If any of the following conditions exist, turn off the
TV, unplug the power cord, and repeat steps 1-9 to en-
sure that the lamp unit and lamp unit door are installed
correctly:
