SECTION 1

SERVICING NOTES

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350 °C.
Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscou-s (sticky, less prone to fl ow)

than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

Special Component Notice

The components identified by mark 9 contain confidential
information.
Strictly follow the instructions whenever the components are
repaired and/or replaced.

NOTE OF REPLACING THE IC2036 AND IC2811 ON
THE DIGITAL AUDIO BOARD

IC2036 and IC2811 on the DIGITAL AUDIO board cannot
exchange with single. When these parts on the DIGITAL AUDIO
board are damaged, exchange the entire mounted board.

NOTE OF REPLACING THE IC3500 AND IC3501 ON
THE HDMI RE PC BOARD

IC3500 and IC3501 on the HDMI RE PC board cannot exchange
with single. When these parts on the HDMI RE PC board are
damaged, exchange the entire mounted board.

1. Enter update mode automatically after power on.

2. The messages “UPDATE” and “PLAY.DISC” are displayed
alternately every one second.

From this step, all user operation is prohibited. Power off is

also prohibited.

If main u-com was failed to update, nothing is displayed.

3. Connect CD player to COAXIAL BD/DVD IN jack (J2301 on
the DIGITAL board), and play update CD.

Update is started when DSP detect update signal. From this,

same as normal case.

SPDIF UPDATE VERSION MODE

Function that displays the version number to check whether SPDIF
update is necessary or not.

Procedure:

1. While pressing [MOVIE] and [MUSIC] buttons, press the

] button to turn on the main power.

[

?/1

2. The message “VER X.XXX” is displayed. “X.XXX” is calcu­lated by adding all fi rmware version.

Example:
(MAIN ver. + DSP ver. + SOUND TUNE ver. + 7)/10 =
Displayed version
MAIN = 1.02, DSP = 1.01, SOUND TUNE = 1.00
↓
(1.02 + 1.01 + 1.00 + 7)/10 = 1.003

1.003 = X.XXX

Procedure:

Normal case

1. While pressing [MOVIE] and [M-TURBO] buttons, press the
[

] button to turn on the main power.

?/1

2. The messages “UPDATE” and “PLAY.DISC” are displayed
alternately every one second.

After this step, all user operation is prohibited except power

off. To cancel this mode, power off or AC power cord pull out
is required.

3. Connect CD player to COAXIAL BD/DVD IN jack (J2301 on
the DIGITAL board), and play update CD.

Update is started when DSP detect update signal. The message

“UPDATING” is displayed blinks every one second.

From this step, all user operation is prohibited. Power off is

generator

Procedure:

1. Turn on the set.

2. Input the following signal from signal generator to FM an­tenna input directly.

Carrier frequency: A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation : 75 kHz
Modulation : 1 kHz

Use 75 ohm coaxial cable to connect signal generator and the set.

Note:

You cannot use video cable for checking.

Use signal generator whose output impedance is 75 ohm.

3. Set to FM tuner function and scan the input FM signal with
automatic scanning.

4. Confi rm that input frequency of A, B and C are detected and
automatic scanning stops.

set

When the station signal is received in good condition, automatic
scanning stops.
