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.
PRODUCT SAFETY NOTICE
CHAPTER 1 GENERAL ADJUSTMENTS
SAFETY INSTRUCTIONS
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 the 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.

normal?
• Has dust accumulated in the FAN?
If the output voltage is not abnormal,
replace the faulty FAN with a new one.
• Check the faulty device through the self
diagnostics function under SERVICE mode.
• Does BUS line (SOL, SDA) work normally?
If the BUS line is under abnormal
conditions, replace the faulty device with
a new one.

LAMP UNIT REPLACEMENT
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 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.
Cautions when replacing LAMP UNIT
All manuals and user guides at all-guides.com

- 14 -
1. Turn off the TV and unplug the power cord.
2. STOP! Allow the lamp to cool for at least one (1) hour
before replacing it.
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.
4. Using a manual screwdriver, loosen two screws on the
lamp unit.
5. Grasp the lamp unit handle and gently pull the lamp unit
straight out of the TV. Set the old lamp unit aside.
6. Carefully insert the new lamp unit straight into the TV
until it is fully seated.
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-
driver.

- 15 -
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:
No picture
Dark picture
TV will not turn on

LIGHT ENGINE REPLACEMENT
Cautions when replacing LIGHT ENGINE
LIGHT ENGINE is a heart of TV which emits high heat.
Make sure to replace it after turning off the TV and wait
for sufficient cool down. (More than one hour is recom-
mended.)
Do not add any impact during replacement; otherwise,
some parts may be damaged.
Do not touch any optical lens. Adhesion of dirt may
deteriorate its performance.
Do not loosen any screw other than those to be removed
for adjustment or replacement.
LIGHT ENGINE emits ultraviolet rays when the TV is
ON. Make sure to be careful.
Read DMD bias value described in alphabet from the
data bar code. In service mode, DMDB value is con-
verted and fixed by the following table.
Refer to Service Mode for adjusting the service mode.
DMDB

DMD value in bar
code
Adjusted value
(Hex)
1-2. Adjustment is made by service mode. The adjusting
items consist of CWDL, CWDH and DMDB.
When CW delay number of the data bar code is 0450:
Double 45.0 to form hexadecimal number (HEX).
The adjusted value becomes “5A” for CWDL and “00”
for CWDH.
If hexadecimal number forms 3 or 4 digits, the latter 2
digits indicate CWDL while the first 2 digits indicate
CWDH.
(For 3 digits, CWDH=0*)
Note:
For converting decimal number to hexadecimal num-
ber, see the conversion table on the next page.

1. Replacement of Light Engine Unit
1-1. When Light Engine Unit is replaced with a new one, the
adjustment is required. Adjusted values are described
in bar code, and the values of bar code must be con-
verted to the adjusted values for the setup.
There are 2 types of bar code.
