CHAPTER 1. IMPORTANT SERVICE SAFETY PRECAUTION
[1] IMPORTANT SERVICE SAFETY PRECAUTION
1. WARNING
1. For continued safety, no modification of any circuit should be attempted.
2. Disconnect AC power before servicing.
2. 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 220 - 240 volt AC outlet. (Do not use an isolation transformer 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.
• A true RMS reading multimeter should be used for this test, especially where the equipment uses a switch mode power supply which may result in
very non-sinusoidal leakage current.
• 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 1.75 Vrms (this corresponds to 0.7 mA. peak 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 " " . 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.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the
servicing guidelines which follow:

[2] 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:
• For the Inverter PWB Units the type used in nickel, so they are marked as LFn:.
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.

[Adjustment]
Check that the values on page 7/13 of process adjustment are set as below. If not, change them accordingly.
1. Display the current adjustment status at point 6. (Page 8/13 of process adjustment)
The display for checking the adjustment status is toggled by pressing the “6” button on the remote control.
(Normal OSD display → “6” → display for check (OSD disappears) → “6” →normal OSD display → . . . )
2. Read the value of the luminance meter. x=0.272 , y =0.277
3. Change MGAMMA R6/MGAMMA B6 (Adjustment offset value) on page 9/13 of process adjustment so that the values of the luminance meter
approach x=0.272 and y =0.277.
(Basically, G is not changed. If adjustment fails with R and B, change G. When G is lowered, the weaker of R and B must be fixed.)
4. Display the adjustment status of the current point 5. (Each time the “5” button on the remote control is pressed, the adjustment status check display is toggled.)
(Normal OSD display → “5” → Check display (OSD disappears) → “5” →Normal OSD display → . . . )
Change M GAMMA R5/M GAMMA B5 (adjustment offset value) on page 9/13 of process adjustment so that the values of the luminance meter
approach x = 0.272 and y = 0.277.
5. Repeat step 4) for points 4, 3, 2, and 1.

12. Lamp error detection
1. Function
This LCD color TV set incorporates a lamp error detection feature that automatically turns off the power for safety under abnormal lamp or lamp
circuit conditions. If by any chance anything is wrong with the lamp or lamp circuit or if the lamp error detection feature is activated for some reason, the following will result.
i) The power is interrupted in about 6 seconds after it is turned on.
(The power LED on the front of the TV set turns red from green and keeps blinking in red: ON for 250 ms and OFF for 1 sec).
ii) If the above phenomenon i) occurs 5 times consecutively, it becomes impossible to turn on the power. (The power LED remained red).
2. Measures
i) Checking with lamp error detection OFF
Enter the adjustment process mode, referring to "3. Entering and exiting the adjustment process mode."
If there is a problem with the lamp or lamp circuit, the lamp will go out. (The power LED is green.)
Then, you can check the operation to see if the lamp and lamp circuit are in trouble.
ii) Resetting the lamp error count
After the lamp and lamp circuit are found out of trouble, reset the lamp error count. If a lamp error is detected five consecutive times, the
power cannot be turned on. Using the cursor (UP/DOWN) key, move to the cursor to [L ERR RESET], Line 6 on adjustment process mode
service page 10/13. With the cursor (LEFT/RIGHT) keys, select the [L ERR RESET] value. Finally press the cursor (OK) keys to reset the
value to "0". Reset to "0 "
