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 having with 5000 ohm per volt,

or higher, sensitivity or measure the AC voltage 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.

LC-37D40U: F701 (8A, 125V) F4701, F5701 (3A~, 250V, 115°C) LC-45D40U: F7801 (8A, 250V) F702, F703 (5A, 125V) F4701, F4703, F5701 (3A~, 250V, 115°C)

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 120 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.

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.

ADJUSTMENT PROCEDURE

The adjustment values are set to the optimum conditions at the factory before shipping. If a value should become improper or an adjustment is required due to part replacement, make an adjustment according to the following procedure.

1. After replacement of any PWB unit and/or IC for repair, please note the following.

When replacing the following units, make sure to prepare the new units loaded with updated software. MAIN Unit: DUNTKD640FM06 (LC-37D40U) / DUNTKD640FM07 (LC-45D40U) IF Unit: DUNTKD643FM06 (LC-37D40U) / DUNTKD643FM07 (LC-45D40U)

2.Upgrading of each microprocessor software

Caution: Never "POWER OFF" the unit when software upgrade is ongoing. Otherwise the system may be damaged beyond recovery.

2-1. Software version upgrade

The model employs the following software.

» Main software » Monitor microprocessor software

The main software and the monitor microprocessor software can be upgraded by using a general-purpose SD memory card. The followings are the procedures for upgrading, explained separately for each of the main software, the monitor microprocessor software.

2-2 Main software version upgrade

Get ready before you start

» SD memory card of 32MB or higher capacity » PC running on Windows 98/98SE/ME/2000/XP operating system » SD memory card reader/writer with USB connectivity. » SD memory card formatting software

(Downloadable at http://panasonic.jp/support/audio/sd/download/sd_formatter_e.html)

LC-37D40U LC-45D40U

Preparations

To upgrade the main software, it is necessary to get ready the SD card for version upgrade before you start. Follow the steps below and create the SD card for version upgrade.

1 Insert the SD card into the SD card reader/writer. Start the SD card formatting software. Click [Format].

(When you have the drive options, select the drive where the SD card is inserted before you proceed.)

2 When the formatting is over, the following window appears. Click [OK].

3 Click [Exit] to finish the formatting.

Note: When you are done, take out the SD card once to make sure it is finished, and then insert it again.

4 Copy the binary image file M150Axxx.SDC (named temporarily) for version updade to the root directory

(folder) of the SD card drive.

Note: In the SD card drive, do not store other folders or unrelated files, or more than one binary image files for

version upgrade. Now the SD card for version upgrade is ready.

LC-37D40U LC-45D40U

How to upgrade the software

1 Shut off the AC power (i.e. unplug the AC cord). 2 Insert the SD card for version upgrade (prepared as above) into the service socket located lower side from

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 main software version information.

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 M150Mxxx.SDC (named temporarily) for monitor microprocessor software version upgrade to the SD card drive.

How to upgrade the software

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 lower side from

center at terminals, above S-VIDEO terminal in the rear of the unit, in a way that the cut corner of the SD card comes at the upper 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 Turn on the AC power (i.e. plug in the AC cord).

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).
