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:

FOR CONTINUED PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITH SAME TYPE FUSE.

F7001(6.3A/250V) -LC-80LE657E/RU/LC-90LE757E/K/RU

• 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 1.05 V peak (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.

DVM

 BEFORE RETURNING THE RECEIVER

AC SCALE

(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 220~240 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.

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.

LC-70LE747E/RU,80LE657E/RU,90LE757E/K/RU

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:

L Fa

Indicates lead-free solder of tin, silver and copper.

L F a/a

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.

3. EEP RECOVER (Page 21/21)

Retrieval of EEP adjustment value from storage area.

4. MONITOR ERR CAUSE (Page 1/21)

Display of a cause (code) of Error from Monitor microprocessor.

The cause of Error is recorded in EEPROM whenever it is possible.

Checking this code will be useful in finding a problem when you repair the troubled set.

1) This displays Error code and time when the error occurred.

The latest error is displayed on “1)”.

The error that happens ahead of “1)” is displayed on “2)”.

2) The character depends on the way how to acquire Time Information.

T: Time is acquired from digital broadcasting

This doesn’t contain “Time offset” which is considered a time difference and Daylight-Saving Time, etc. ...

U: Time is acquired from analog broadcasting (teletext) B: Accumulation time of Backlight

In the case that Time information cannot be acquired, “B” is displayed.

Example) In this example, it is shown that the error occurred 3 times.

1) 16 T07/01/01 12:03 Error code: 16 (lamp error) Time: 07/01/01 12:03 * It is latest Error. * Time is acquired from digital broadcasting. * Time is UTC which doesn't have Time offset.

2) 16 U01/01/01 04:07 Error code: 16 (lamp error) Time: 07/01/01 04:07 * It is Error that happens ahead of “1)”. * Time is acquired from analogue broadcasting.

3) 16 B00000004:11 Error code: 16 (lamp error) Accumulation time: It is displayed that 4:11 have passed after Backlight driving. * It is Error that happens ahead of “2)”.

7. 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.

1) The power is interrupted in about 500ms after it is turned on.

(A central icon on the front of the TV flash on and off.: ON for 400ms and OFF for 1600ms.)

2) If the above phenomenon 1) occurs 5 times, it becomes impossible to turn on the power.

(A central icon keep flashing on/off.)

2. Measures

1) Set the lamp error detection to OFF

Enter the adjustment process mode, referring to “2. Entering and exiting the adjustment process mode”.

The adjustment process mode can ignore “5 times count”, so If the above phenomenon 1) occurs 1~4 times, the lamp will go out.

If Lamp Error detection pin [22pin of PD: P3801/19pin of IC2004] is “High” by a trouble with the lamp and lamp circuit, it can boot-up by the adjustment process mode.

Please execute “Lamp Error detection off-mode”.

Unplug the AC power cord of running TV set to force off the power.

While holding down the “VOL (+)” and “CH ( )” keys on the set at once, plug in the AC power cord to turn on the power.

After a central icon flash off, separate the fingers from key on the set.

Then, you can check the operation to see if the lamp and lamp circuit are in trouble.

If you fail boot-up, retry the procedure.

2) Resetting the lamp error count

After the lamp and lamp circuit are improved from a trouble, reset the lamp error count.

(Because the power cannot be turned on, if a lamp error is detected 5 consecutive times.)

a) Enter the adjustment process mode, referring to “2. Entering and exiting the adjustment process mode”.

b) Using the cursor ( / ) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode service page 2/21.

c) With the cursor ( / ) keys, select the [LAMP ERROR RESET] value.

Finally press the cursor (OK)., the count is reset.

Check LAMP ERROR Count on adjustment process mode Page 2/21.

OPC: OFF

Asing Time: Min, 60 minute

[Input signal condition] : HDMI 1080i 15IRE (LO), 78IRE (HI)

[Adjustment reference device] : Minolta CA-210

[Adjustment procedure]

1) Display the current adjustment status at R/G/B_GAIN (HI). (Page 11/21 of process adjustment)

The signal of 78IRE is input.

2) Read the value of the luminance meter. x=0.272, y =0.277

3) Change R_GAIN (HI)/ B_GAIN (HI) (Adjustment offset value) on page 11/21 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 or B must be fixed.)

4) Display the adjustment status of the current R/G/B_GAIN (LO).

The signal of 15IRE is input.

Change R_GAIN (LO)/ B_GAIN (LO) (adjustment offset value) on page 11/21 of process adjustment so that the values of the luminance meter approach x =0.272 and y = 0.277.

5) Both HI and LO are repeating the step from 1 to 4 until becoming an aim value.

[Adjustment reference standard value]

Adjustment spec ± 0.002 Inspection spec ± 0.004 (point LO)

Adjustment spec ± 0.001 Inspection spec ± 0.002 (point HI)

6) After completing adjustments, set EEP SAVE (Page 21/21) to ON in the process menu to save the white balance adjustment value.

Display method

• Refer to Table 1.

• LED that can be used are only one of the central icon (Emblem Unit).

This expresses the error situation by combining blinking at low speed and blinking at high speed.

• For this model, the blinking pattern displayed first is only a low-speed blinking.

This expresses a rough content of the error.

• For this model, details are displayed by a high-speed blinking

This expresses details of the error.

Details are distinguished by the blinking frequency.

• It doesn’t return to the outline display again (blink at low speed) by pushing the MENU key (The toggle is not done).

Please confirm “MONITOR ERR CAUSE” of the adjustment Process mode (1/21 page), when the error doesn't reproduce by having returned from the error.

• The process of the upgrade is expressed by the brightness of point LED that smoothness changes.

• The upgrade completion is expressed by the LED brightness that changes in a staircase pattern.
