SAFETY PRECAUTION

Service Manual

IMPORTANT SERVICE SAFETY PRECAUTION

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: FO R C O N T INUED PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE FUSE.

F701 (125V 8A)
F4702 (250V 6.3A)

• 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 0.75 Vrms (this corresponds to 0.5 mA rms AC.) or
more is excessive and indicates a potential shock hazard which
must be corrected before returning the monitor to the owner.

DVM

BEFORE RETURNING THE RECEIVER (Fire &
Shock Hazard)

Before returning the receiver to the user, perform the following
safety checks:

3. 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.

4. 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.

5. To be sure that no shock hazard exists, check for leakage current in
the following manner.

• Plug the AC cord directly into a 120 volt AC outlet.

• Using two clip leads, connect a 1.5k 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.

SAFETY NOTICE

Many electrical and mechanical parts in LCD color 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 components having such features

are identified by " " and shaded areas in the Replacement Parts List
and 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.

REMPLACER LE FUSIBLE

F701 (125V 8A)
F4702 (250V 6.3A)

VERIFICATIONS CONTRE L'INCEN-DIE ET LE
CHOC ELECTRIQUE

Avant de rendre le récepteur à l'utilisateur, effectuer les vérifica­tions suivantes.

Inspecter tous les faisceaux de câbles pour s'assurer que les fils

3.
ne soient pas pincés ou qu'un outil ne soit pas placé entre le châs­sis et les autres pièces métalliques du récepteur.

4.

Inspecter tous les dispositifs de protection comme les boutons de
commande non-métalliques, les isolants, le dos du coffret, les cou­vercles ou blindages de réglage et de compartiment, les réseaux
de résistancecapacité, les isolateurs mécaniques, etc.

5.

S'assurer qu'il n'y ait pas de danger d'électrocution en vérifiant la
fuite de courant, de la facon suivante:

•

Brancher le cordon d'alimentation directem-ent à une prise de cou­rant de 120V. (Ne pas utiliser de transformateur d'isolation pour
cet essai).

A l'aide de deux fils à pinces, brancher une résistance de 1.5 kΩ
10 watts en parallèle avec un condensateur de 0.15µF en série
avec toutes les pièces métalliques exposées du coffret et une terre
connue comme une conduite électrique ou une prise de terre
branchée à la terre.

•

Utiliser un voltmètre CA d'une sensibilité d'au moins 5000Ω/V pour
mesurer la chute de tension en travers de la résistance.

•

Toucher avec la sonde d'essai les pièces métalliques exposées qui
présentent une voie de retour au châssis (antenne, coffret métalli­que, tête des vis, arbres de commande et des boutons, écusson,
etc.) et mesurer la chute de tension CA en-travers de la résistance.
Toutes les vérifications doivent être refaites après avoir inversé la
fiche du cordon d'alimentation. (Si nécessaire, une prise
d'adpatation non polarisée peut être utilisée dans le but de termin­er ces vérifications.)
La tension de pointe mesurèe ne doit pas dépasser 0.75V (corre­spondante au courant CA de pointe de 0.5mA).
Dans le cas contraire, il y a une possibilité de choc électrique qui
doit être supprimée avant de rendre le récepteur au client.

PRECAUTIONS FOR USING LEAD-FREE SOLDER

Employing lead-free solder

• “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:

Indicates lead-free solder of tin, silver and copper. Indicates lead-free solder of tin, silver and copper.

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.

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.

• Be careful when replacing parts with polarity indication on the PWB silk.

2) Connect the white balance adjustment tool to the set.

[Adjustment procedure]

1) Using the remote controller, transmit the “monitor adjustment process” code.

2) Set the 6th point to the specified gradation level. With the strongest color being fixed,
turn down the R, G and B settings to their reference levels.

3) Set the 5th point to the specified gradation level. Correct the G setting (800 x 6th­point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.

4) Set the 4th point to the specified gradation level. Correct the G setting (656 x 6th­point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.

5) Set the 3rd point to the specified gradation level. Correct the G setting (528 x 6th­point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.

6) Set the 2nd point to the specified gradation level. Correct the G setting (352 x 6th­point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.

7) Set the 1st point to the specified gradation level. Correct the G setting (192 x 6th­point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.

8) With the MSET0003 command, write the adjustment values and turn off the AC
power.

* Initial R, G and B settings at point 6: Gradation level set at 928
* Initial R, G and B settings at points 1 thru 5: Corrected G setting at each point
(This is because the adjustment is made to achieve the same remainder of RGB setting /

1. Get ready the PC with COM port (RS-232C) running on Windows 95/98/ME/2000/XP operating system, as well as the RS-232C cross cable.

2. Start the unit with the RS-232C cable connected.

3. Start the terminal software. (The freeware readily available on the Internet will do.)

4. Make the following settings.

Baud rate 9,600 bps
Data LENGTH 8 bit
Parity bit None
Stop bit 1 bit
Flow control None

5. If the settings are correct, the terminal software indicates “ERR” against pressing of the “ENTER” key.

6. After the settings are done correctly, it is possible to make an adjustment by typing in the command shown in the table below and pressing the
“ENTER” key on the keyboard.

7. Command entry is successful if the terminal software indicates “OK” when the “ENTER” is pressed. If “ERR” is shown, retry to enter the command.

8. Send the process mode switching command to switch from the RS232C operation mode to the process mode.

KRSW0001: “ERR” is returned.

KKT10037: When “OK” is returned, the process mode becomes active. When “ERR”, start over from KRSW0001.

9. Send each adjustment command.

9. Initialization to factory settings

CAUTION: When initialization is performed, all user setting data including the channel settings are initialized. Be cautious when making this adjust-

ment.

(The adjustments done in the adjustment process mode are not initialized.)

Adjustment item Adjustment conditions Adjustment procedure

1 Initialization It turns off with AC power

supply.

After the adjustment, cancel the adjustment process mode.
To exit the adjustment process mode, unplug the AC power cable from the outlet to make a
forced shutdown. (When the power was turned off with the remote controller, once unplug the
power cable and plug it again. In this case, wait 10 seconds or so before plugging.)

Enter the adjustment process mode.
Bring the cursor on to [INDUSTRY INIT] in page 2/32.
Set to [ON] using [VOL] key, and press [ENTER] to execute the initialization.
When the version number screen shows up on the green background and “SUCCESS”
gets displayed at the top on screen, it means the procedure has been successfully car­ried out.
(If an error occurs, “ERROR” is displayed on the red background.)

•Turn off the AC power.
*Never shut off the power during the initialization process.
The following settings are initialized in this adjustment.

1) User setting
