IMPORTANT SERVICE SAFETY PRECAUTION
Ë
Service work should be performed only by qualified service technicians who are thoroughly
familiar with all safety checks and the servicing guidelines which follow:
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
CAUTION: FOR CONTINUED PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE F3301(2A, 250V), F3302(1.25A, 250V),
F6500 (1.25A, 250V) AND F6501 (1.25A, 250V)
FUSE.
BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)
Before returning the receiver to the user, perform
the following safety checks:
1. Inspect all lead dress to make certain that leads are
not pinched, and check that hardware is not lodged
between the chassis and other metal parts in the
receiver.
2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
insulators, etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
• Plug the AC cord directly into a 110~240 volt AC outlet,
and connect the DC power cable into the receiver's
DC jack. (Do not use an isolation transformer for this
test).
• Using two clip leads, connect a 50k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all
exposed metal cabinet parts and a known earth ground,
such as electrical conduit or electrical ground connected
to an earth ground.
• Use an AC voltmeter having with 5000 ohm per volt, or
higher, sensitivity or measure the AC voltage drop
across the resistor.
• Connect the resistor connection to all exposed metal
parts having a return to the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the AC voltage drop
across the resistor.
All checks must be repeated with the AC cord plug
connection reversed. (If necessary, a nonpolarized
adaptor plug must be used only for the purpose of
completing these checks.)
Any reading of 0.75V peak (this corresponds to 0.5
mA. peak AC.) or more is excessive and indicates a
potential shock hazard which must be corrected before
returning the monitor to the owner.
Many electrical and mechanical parts in LCD television
have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
and shaded areas in the
Schematic Diagrams.
For continued protection, replacement parts must be
identical to those used in the original circuit.
The use of a substitute replacement parts which do not
have the same safety characteristics as the factory
recommended replacement parts shown in this service
manual, may create shock, fire or other hazards.
components having such features are identified by “ å”
"All PWBs" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on
the PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:
L Fa
Indicates lead-free solder of tin, silver and copper.
2 Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional
lead wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend
you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering
bit, contact our service station or service branch in your area.
3 Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead
solder by 40°C, and as it has poor solder wettability , you may be apt to keep the soldering bit in contact with the
PWB for extended period of time. However, Since the land may be peeled off or the maximum heat-resistance
temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady soldering
condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on
and off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit
after every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.

ADJUSTING PROCEDURE OF EACH SECTION
The best adjustment is made before shipping. If any position deviation is found or after part replace is performed,
adjust as follows.
Preparation for adjustments
Use the dedicated AC adaptor or stable DC power supply.
AC adaptor: UADP-A034WJPZ
DC power supply: 12V 4.5A
1.Adjusting procedure
• Checker adjustment
Power ON (Adjustment processing mode) → +B adjustment → Counter bias adjustment → TAMP (Contrast)
adjustment → White balance adjustment
2.Entering the adjustment processing mode
There are the following two methods.
• Setting the pin (81)(KEY4) or pin (82)(KEY5) of IC2001 (microprocessor) to GND, turn on the power .
• A “POWER” key is made on with pushing an “TV/VIDEO” and “MENU” keys at the same time.(K of the inspection
process mode is displayed by the upper left of the image plane.) → Next, “CH (Ù)” and “VOL (–)” keys are pushed
at the same time.(It becomes the image plane of the adjustment process mode.).....When it is canceled, it is made
to turn it off.(Even off in the “MAIN POWER” key, off with R/C are good.)
3.Key operation in the adjustment process mode
• The receiving channel UP/DOWN is performed with the “CH (ù)/(Ù)” keys.
One push ... The UP/DOWN tuning is performed per channel.
Continuous push ... The UP/DOWN search is performed until a next receivable station is found.
• Various adjustments
The adjustment is performed for each item by the “MENU”, “Menu cursor”, “CH (ù)/(Ù)” or “VOL (+)/(–)” keys
(LCD TV set and remote control).
• Adjustment item is chosen with the Menu cursor upward/downward keys.
• The adjustment item makes a toggle operation with the “MENU” key input. (Next item)
If the “MENU” key is input while the bottom item is selected, it moves to the top item on the next page.
• Press the auto preset button on the remote controller in the adjustment process mode, and the top item of the
next page will show up regardless of which item appears now.
Page 1 → Page 2 → ... → Page 57 → Page 1
• Press the manual memory button on the remote controller in the adjustment process mode, and the top item of
the same page will show up.
• UP/DOWN of each adjustment vale selected is performed with the VOL (+)/(–) keys input.

5.Adjustment
5-1. +B adjustment...Page 1 +B-ADJ
Adjust the voltage of the pin (4) of P1902 to 5.00 ±0.02V with R3714.
Note: Since 5.0V is a reference voltage of all power voltage, adjust it precisely.
5-2. Counter-bias adjustment
Vary the "COM BIAS" setting on Page 2 of the adjustment process mode so that the contrast be sharpest
(black looks most sinking).
5-3. TAMP adjustment
1) Receive the upper left of 75% white half colour bar signal.
2) See if the “Y” reading on page 2 of the adjustment process mode is somewhere following. If not, make the
“PAL TAMP” adjustment to get the “Y” reading in the range of AE thru BD.
3) If the adjustment of “PAL TAMP” is executed, write its adjustment value to the “SECAM TAMP” manually.
(Screen of the page 2 of the adjustment processing menu OSD)
Adjust “RCUTOFF” and “BCUTOFF” on the page 2 of the adjustment processing so as to obtain the colour
of the same level as the standard set.

6. Factory Setting
6-1. Perform a factory setting after completing all adjustments.
6-2. A “POWER” keys is made on with pushing an “TV/VIDEO” and “MENU” keys at the same time.
6-3. “K” of the inspection process mode is displayed on the screen upper left.
6-4. CH (ù) and VOL (+) keys are pushed about 2 seconds at the same time.
6-5. Release keys, if “E” is displayed on the screen upper left and “COMPLETE” is displayed on the bottom of it.
6-6. After a while, a power will be in a standby mode and a setup will be finished.
Note: “First installation” serves on “Deutsch”.
7. Lamp error detection
7-1. Functional description
This LCD colour television has a function (lamp error detection) to be turned OFF automatically for safety
when the lamp or lamp circuit is abnormal.
If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed,
the followings occur.
1 The main unit of television is turned OFF 5 seconds after it is turned ON. (The power LED on the front side
of TV turns from green to red.)
2 If the situation 1 happens 5 times sequentially , television can not be turned ON. (The power LED remains
red.)
7-2. Countermeasures
7-2-1.Check when turning OFF the lamp error detection
When television is turned OFF by the lamp error detection mentioned above, it enters the adjustment
process with the power LED red. Entering the adjustment process turns OFF the error detection and turns
ON TV .
This enables the operation check to detect errors in the lamp or lamp circuit.
Check whether "ERROR NO RESET" on line 3, page 1 of the adjustment process is 1 or more. If it is 1 or
more, it indicates the lamp error detection was executed.
7-2-2.Resetting of the lamp error count
After confirming that the lamp or lamp circuit is normal, reset the lamp error count. Select "ERROR NO
RESET" on line 3, page 1 of the adjustment process and set the number to 0 using the volume button.
