Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the servicing guidelines which follow:

IMPORTANT SERVICE SAFETY PRECAUTION

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 FUSE. F701 (3.15A, 250V), F702 (3.15A, 250V), F703 (2A, 250V), F705 (1A, DC450V), F706 (5A, 250V), F707 (5A, 250V)

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. » 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 0.75 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 " å"

23456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012

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.

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 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.

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

2-3 Monitor microprocessor software version upgrade

Get ready before you begin Get ready the same items as listed in the "Main software version upgrade". Preparation Create the SD card for monitor microprocessor software version upgrade in the same manner as explained in

the "Main software version upgrade". Copy the binary image file for monitor microprocessor software version upgrade to the SD card drive.

How to upgrade the software During the monitor microprocessor software version upgrade, the progress of upgrading is not shown on the

display screen. The upgrading process is seen in the blinking of the power LED.

1 Shut off the AC power to the unit (i.e. unplug the AC cord). 2 Insert the SD card for version upgrade (prepared as above) into the service socket located below left of the

right side cooling fan in the rear of the unit, in a way that the cut corner of the SD card comes at the righthand side.

Note: If the SD card is inserted in a wrong way, the card will go deep inside the unit beyond retrieval. Take due

care to insert the SD card correctly.

3 While depressing the "SYSTEM RESET" button located in the rear left side of the unit, turn on the AC

power (i.e. plug in the AC cord).

Note: After the unit is started, you may release the "SYSTEM RESET" button.

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 have a serious damage beyond recovery (inability to start).

LC-26GA5H/M/X

4 After the unit startup, the power LED starts blinking in green within 10-20 seconds. 5 Wait until the power LED stops blinking, the unit restarts automatically, and the normal startup screen

appears (it will take 2-3 minutes).

6 Shut off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade. 7 Now the software version upgrade is complete.

Note: When you are done with the software version upgrade, start the set, go to the top page of the adjustment

process screen and check the monitor microprocessor software version information.

3. Entering and exiting the adjustment process mode

(1) Before entering the adjustment process mode, press the "TV RESET" button or execute the AV position

RESET in the video adjustment menu. (2) Unplug the AC cord from the outlet to make a forced shutdown. (3) While holding down the "VOL (–)" and "TV/VIDEO" keys at a time, plug the AC cord and turn on the power.

(The "VOL (–)" and "TV/VIDEO" keys should be pressed and held until the display appears.)

The letter " K " appears on the screen. (4) Next, hold down the "VOL (–)" and "CH (Ù)" keys at a time.

Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment

process mode.

When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the

procedure. (5) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to

make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC

cord and plug it again. In this case, wait 10 seconds or so before plugging.)

Caution: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If the settings are tampered in this mode, unrecoverable system damage may result.
