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

» Use an AC voltmeter ha ving with 5000 ohm per v olt,

or higher, sensitivity or measure the A C v oltage drop

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 FUSE.

F701, F702 (5A, 250V) F703 (1A, AC250V), F704 (117°C, 2A)

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.

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 volt AC outlet. » Using two clip leads, connect a 1.5k ohm, 10 watt

TO EXPOSED METAL PARTS

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 b y " å"

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.

Precautions for using lead-free solder

1 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:

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 y ou 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 allo y ed 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.

Removing the stand

Before detaching (or attaching) stand, unplug the AC cord from the AC INPUT terminal.

CAUTION

Do not remove the stand from the TV unless using an optional wall mount bracket to mount it.

Before attaching/detaching stand

Before performing work make sure to turn off the TV.

Before performing work spread cushioning over the base area to lay the TV on. This will prevent it from being

damaged.

NOTE

To attach the stand, perform the above steps in reverse order.

Setting the TV on the wall

CAUTION

Installing the TV requires special skill that should only be performed by qualified service personnel. Customers

should not attempt to do the work themselves. SHARP bears no responsibility f or improper mounting or mounting

that results in accident or injury.

Using an optional bracket to mount the TV

You can ask a qualified service personnel about using an optional bracket to mount the TV to the wall.

Carefully read the instructions that come with the bracket before beginning work.

Vertical mounting Angular mounting

Hanging on the wall

Wall mount bracket. (See the bracket instructions for details.)

Unfasten the four screws used to

secure the stand in place.

Unfasten the screw used to secure the

(Hold the stand so it will not drop from

the edge of the base area.)

No sound

Problem Possible Solution

Check if you pressed TV POWER on the remote control unit.

If the indicator on the TV does not light up, press TV POWER on the remote

control unit.

Is the AC cord disconnected?

Has the power been turned on?

External influences such as lightning, static electricity, may cause improper

operation. In this case, operate the unit after first turning on the power of the TV

or unplugging the AC cord and replugging it in after 1 or 2 minutes.

Is the FUNCTION set correctly? Set it to the TV setting position.

Are batteries inserted with polarity ( , ) aligned?

Are batteries worn out? (Replace with new batteries.)

Are you using it under strong or fluorescent lighting?

Is a fluorescent light illuminated near the remote control sensor?

Is the image position correct?

Are screen mode adjustments such as picture size made correctly?

Adjust the picture tone.

Is the room too bright? The picture may look dark in a room that is too bright.

Is the sleep timer set?

Check the power control settings.

The unit's internal temperature has increased.

Remove any objects blocking vent or clean.

Is connection to other components correct?

Is correct input signal source selected after connection?

Is the correct input selected?

Is picture adjustment correct?

Is "On" selected in "Audio Only"?

Is the volume too low?

Is "Variable" selected in "Output Select"?

Troubleshooting

Cautions regarding use in high and low temperature environments

When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly

delayed. This is not a malfunction, and the unit will recover when the temperature returns to normal.

Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near

a heater, as this may cause the cabinet to deform and the Liquid Crystal panel to malfunction.

PC Control of the TV

When a program is set, the TV can be controlled from the PC using the RS-232C terminal. The input signal

(PC/AV) can be selected, the volume can be adjusted and various other adjustments and settings can be

made, enabling automatic programmed playing.

Attach an RS-232C cable cross-type (commercially available) to the supplied Din/D-Sub RS-232C for the

connections.

NOTE

This operation system should be used by a person who is accustomed to using computers.

Communication conditions

Set the RS-232C communications settings on the PC to match the TV's communications conditions.
