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 CO N TI N UE D PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITH SAME TYPE FUSE.

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.

• 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.

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.

AVIS POUR LA SECURITE

De nombreuses pièces, électriques et mécaniques, dans les téléviseur ACL présentent des caractéristiques spéciales relatives à la sécurité, qui ne sont souvent pas évidentes à vue. Le degré de protection ne peut pas être nécessairement augmentée en utilisant des pièces de remplacement étalonnées pour haute tension, puissance, etc. Les pièces de remplacement qui présentent ces caractéristiques sont identifiées dans ce manuel; les pièces électriques qui présentent ces particularités sont identifiées par la marque " " et hachurées dans la liste des pièces de remplacement et les diagrammes schématiques.

Pour assurer la protection, ces pièces doivent être identiques à celles utilisées dans le circuit d'origine. L'utilisation de pièces qui n'ont pas les mêmes caractéristiques que les pièces recommandées par l'usine, indiquées dans ce manuel, peut provoquer des électrocutions, incendies, radiations X ou autres accidents.

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.

2.3. Monitor microprocessor software version upgrade

Create the USB memory for monitor microprocessor software version upgrade in the same manner as explained in the “Main software version upgrade”.

Copy the file HLNIBxxx.USB and HLNIMxxx.BIN (named temporarily) for monitor microprocessor software version upgrade to the USB memory.

2.3.1 How to upgrade the software

1. Plug AC cord and turn on the TV.

2. After picture displayed, touch the power key for 5seconds.

NOTE: Picture will disappear when you touch the power key, but keep touching it.

3. When the center icon LED blinks, release your finger from the power key.

4. Next, touch the “POWER” key with the “CH ( )” key touching.

5. When the center icon LED turns on, release your finger form the keys.

CAUTION:• The moment this operation is done, the upgrading of the monitor microprocessor software starts. While the upgrade is ongoing, never

power off the unit. Otherwise the upgrade will fail and the system may be serious damaged beyond recovery (inability to start).

• After the monitor microprocessor software is upgraded, also perform the 'Industry Init'.

6. After the unit startup, the upgrade starts. The power led will blink continuously. Also, an upgrade screen will be shown during a minor upgrade.

[Adjustment procedure]

1) Send the “adjustment process” code using the remote control.

2) Set the point 6 to the specified gradation, specify the strongest color as the fixed

color, and adjust the RGB so that it becomes the standard value through negative adjustment. Then compare the R and G values; based on the result, calculate the Ye value in the following conditions. R > G: Ye = G x 1.05 R G: Ye = R x 1.05 * If the Ye value exceeds the initial value (input gradation x 4), it is rounded to that

value or less.

3) Set the point 5 to the specified gradation, set the G correction value (692 x G value of

point 6/916) (fractions rounded off) and the Ye correction value (692 x Ye value of point 6/916) (fractions rounded off), and adjust the RB so that it becomes the standard value.

4) Set the point 4 to the specified gradation, set the G correction value (532 x G value of

point 6/916) (fractions rounded off) and the Ye correction value (532 x Ye value of point 6/916) (fractions rounded off), and adjust the RB so that it becomes the standard value.

5) Set the point 3 to the specified gradation, set the G correction value (464 x G value of

point 6/916) (fractions rounded off) and the Ye correction value (464 x Ye value of point 6/916) (fractions rounded off), and adjust the RB so that it becomes the standard value.

6) Set the point 2 to the specified gradation, set the G correction value (296 x G value of

point 6/916) (fractions rounded off) and the Ye correction value (296 x Ye value of point 6/916) (fractions rounded off), and adjust the RB pattern so that it becomes the standard value.

7) Set the point 1 to the specified gradation, set the G correction value (180 x G value of

point 6/916) (fractions rounded off) and the Ye correction value (180 x Ye value of point 6/916) (fractions rounded off), and adjust the RB so that it becomes the standard value.

8) Write the adjustment value by the MSET0003 command and turn off the AC power.

[2] PUBLIC MODE SETTING PROCEDURE

1. How to start Public Mode

• There are the following 3 ways to get the public mode setup screen displayed.

In the adjustment process mode, turn on “PUBLIC MODE”

1) Plug AC cord and turn on the TV.

2) After picture displayed, touch the “POWER” key for 5seconds.

NOTE: Picture will disappear when you touch the power key, but keep touching it.

3) When the center icon LED blinks, release your finger from the power key.

4) Next, touch the ”POWER” key with the “CH ( )” key and “VOL (+)” key touching.

5) When the center icon LED turns on, release your finger form the keys.

It’s same as from 1) to 3)

4) Next, touch the “POWER” key with the “INPUT” key and “CH ( )” key touching.

5) When the center icon LED turns on, release your finger form the keys.

6) Get the password input screen displayed.

Procedure

˴The input starts with the leftmost digit. ˴Use the numeric keys [1] thru [9] and [0] keys on the remote controller. ˴The other keys are not acceptable. ˴With a numeric-key input, "_" will change to "˴". ˴The input position will move one digit to the right. ˴With all the 3 digits entered, the password will be verified.

LC-40/46/52/60LE820UN

7) The 3-digit password is now verified.

The password [0] [2] [7] provides for the public mode screen. (This screen comes on with whatever adjustment process settings.) With any other passwords, the screen changes to the normal mode.

2. How to exit Public Mode

There are the following ways to quit the public mode setup screen.

• Turn off “PUBLIC MODE” in the adjustment process mode. ( ) ← This way alone is not for quitting the setup screen, but for quitting the mode itself.

• Turn off the power with the “POWER” key. ( )

• Select “EXECUTE”. ( )

... “PUBLIC MODE” stays on in the adjustment process mode. ... The settings will be back to the factory ones.

3. Public Mode Setting Values

• With the factory settings made, the public mode settings get initialized. (The adjustment process remains intact.)
