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: FOR CONTINUED PROTECTION A GAINST A RISK OF FIRE REPLACE ONLY WITH SA ME TYPE F3701 (2.0A, 250V), F3301

A V

(1.25A, 250V), F6501 (1.25A, 250V) AND F6502 (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 A C outlet, and connect the DC power cable into the receiv er's DC jack. (Do not use an isolation tr ansf ormer for this test).

• 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 ha ving 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 e xcessive 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 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.

identifiées par la marque " å " 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

1 Employing lead-free solder

"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 ho w 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, remov e 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. Mak e sure to turn on and off the power of the bit as required. If a different type of solder sta ys 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.

ADJUSTING PROCEDURE OF EACH SECTION

1. Pre-adjustment preparations

Use the specific AC adaptor or a stable DC power supply as power source.

LC-13/15/20S2U AC adaptor: UADP-A044WJPZ DC power supply: 12V, 5.0A

(1) Entering the adjustment process mode

There are two ways to call this mode.

» Press "MENU" and "TV/VIDEO" at once, and the power is turned on (inspection process started). Then press

"CHANNEL DOWN" and "VOLUME DOWN" at once.

» Set the KEY4 (pin (81) of microprocessor) or KEY5 (pin (82) of microprocessor) terminal to the "L" level. Now

turn on the power.

(2) Key operation in the adjustment process

Basic behavior

» Use the "CHANNEL UP/DOWN" key or the "DIRECT CHANNEL SELECT" key to choose a channel. » Use the "CURSOR UP/DOWN" key to select an item to adjust. (Let's say that the cursor is on the lowermost item

and the "CURSOR DOWN" key is pressed. The uppermost item on the next page will be selected. When the "CURSOR UP" key is pressed with the uppermost item being highlighted, on the other hand, the lowermost item on the preceding page will be selected.)

» Use the "VOLUME UP/DOWN" key or the "CURSOR RIGHT/LEFT" key to adjust the setting of a selected item. » Press the "MENU" key to go to the next item. (When this key is pressed with the lowermost item being

highlighted, the uppermost item on the next page will be selected.)

Hierarchical structure

» Press the "ENTER" key on any item other than I2C DATA on page 4, and the item's setup page will show up. » To quit the setup page, press the "FLASHBACK" key.

LC-13S2U-S

2.Adjusting procedure

(1) Getting initialized

1) Set pins (81) and (82) of the IC2001 microprocessor to GND. Turn on the power.

2) Make sure the model number is A622. * Note: The model number cannot be selected.

3) Select the screen size (13/15/20 inches). Select the inch size according to the 13" model.

(2) +B adjustment

1) Receive the standard color bar signal.

2) Rotate R3710 (semi-fixed variable resistor) to adjust the voltage at pin (4) of P3701 on the sub PWB to

5.00V±0.02V.

Note: Be sure to adjust this PWB in pairs with the main PWB.

Adjust to the 5.00V level as exactly as possible because this level is used as reference for all the other

supply voltages.

(3) Common bias adjustment

1) Adjust the "COM BIAS" setting on adjustment process page 2 so that the contrast goes to maximum (black most accentuated). (For this adjustment, receive a B/W broadcast channel.)

(4) White balance (cut-off and gain) adjustment

1) Receive the black signal (white 40%). Adjust the "RCUTOFF" and "BCUTOFF" settings on adjustment process page 3 to have the black color temperature as specified.

2) Receive the white 80% signal. Adjust two of the "R-GAIN", "G-GAIN" and "B-GAIN" settings in the decreasing direction to have the white color temperature as specified. Note:Make sure at least one of the "R-GAIN", "G-GAIN" and "B-GAIN" settings is "0".

3) Check to see if the black and white color temperatures are as specified. If not, repeat the above steps 1) and

2).

4) 480P mode white balance adjustment Set the "D2 GCUTOFF" setting to -7. Check to see if the black and white color temperatures are as specified. If not, repeat the steps 1) thru 3). Adjust also the "D2 R/G/B CUTOFF" and "D2 R/G/B-GAIN" settings.

(5) Factory settings

1) Starting the factory process mode Press "MENU" and "TV/VIDEO" at once, and the power is turned on (inspection process started). Then press "CHANNEL UP" and "VOLUME UP" at once.

2) Factory settings at a glance
