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.

• 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.

F701 (4A/250V)

 BEFORE RETURNING THE RECEIVER (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.

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

TO EXPOSED METAL PARTS

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.

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.

Before using I2C method is necessary to install Visual I2C software following next procedure.

1. Install Visual I2C release V3.2.3b from file (“Setup_Visual_I2C_v3-2-3b8h.exe”).

• It’s strongly recommended to accept the suggested default folder (“C:\Program Files\Micronas\Visual I2C”).

2. Install Visual I2C VCTp extension from file (“Setup_VI2C_for_VCT6wxyP_v0111.exe”).

• It’s interesting to change default folder to same as Visual I2C (“C:\Program Files\Micronas\Visual I2C”).

• During this installation process is possible to install also a complementary software to manage NVM memories .

This installation is not needed, for this reason uncheck the option when the setup program ask to you. In case of installation it’s interesting to change default folder to same as Visual I2C (“C:\Program Files\Micronas\Visual I2C”).

3. Install Parallel driver depending of your Windows version from existing files inside the Visual I2C installation folder “C:\Program Files\Micro

nas\Visual I2C\Port_Driver”, following next criteria:.

1) Windows 98/Me (“Setup_LptDrv_v0104_9x.exe”).

2) Windows NT (“Setup_LptDrv_v0104_NT_2000.exe”).

5 – 8

LC-26SA1E/RU, LC-32SA1E/RU

3) Windows Xp/2000 (“Setup_LptDrv_v020201_XP_2000.exe”). After installing Visual I2C, the new generated file structure should look like this:

4. Check installation LPT driver using “C:\Program Files\Micronas\LptDrv\LptDrvTest.exe”. After run this software, if LPT driver is installed properly

must appear this screen:

• If the result is not OK, check inside PC bios: Parallel Port Mode=EPP

To run VCTp software update program, please click over “VCTP” icon from “START\All programs\Micronas\Visual I2C\IC\VCTP” and after Visual I2C finish their starting process click on “TVT” module. As additional method, it’s possible to create a direct access to “C:\Program Files\Micronas\Visual I2C\ic\vct6wxyP\vctq_tvt.vi2c” and launch it from Windows Desktop.

3. Wait until “40” appears in Bootloader Version field.

4. Close DOS pop up windows pressing any key (“Press any key to continue...”.).

5. Click on the “Erase flash” button and wait for a seconds and set the AutoRead to OFF.

6. Check in the desired software version is selected in the “Load BinaFlash” option. If it’s not the correct one, please double click on the file name and

select it. The first time this software is use it’s necessary to confirm write Addressing margin as from 0x0 to 0x7ffff.

7. Click on the “Load Bin → Flash” to start updating process.

8. When the updating process finishes, the “Progress” pop up window automatically closes. If appears some problem during the updating process a

error label appears in the filename information line.

If the TV has problem to enters in the”Bootloader mode”, it’s possible to force it by hardware method. This alternative method is described below:

1. Switch off TV set or hold VCTp RESET line to GND.

2. Pull down SCL line (pin 1) to GND (pin 3) in P2306 connector.

3. Switch on TV set or release VCTp RESET line.

4. Release SCL pull down after minimum of 2 seconds.

5. Check if VCTp is in bootloader mode with Autoread setting in ON.

6. Wait until “40” appears in Bootloader Version field.

7. Follow instruction from item 5 on software method.

Sometimes, depending on the PC hardware, the progress bar runs very fast (Normal time: 1 minute) or some error message appears in the filename information line. This means it’s necessary to modify some parameter of LPT port, for this reason select “LPT Preferences” on the “File\Preferences...” menu and increase Delay from “0” to “1” or “2” (normally, these values are the best choice).
