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.
SECTION 1
SERVICING NOTES
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free 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 flow)
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 9contain confidential
information.
Strictly follow the instructions whenever the components are
repaired and/or replaced.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

played continuously until any user operation).
Procedure:
After update is abnormal exit, and set is power on again
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
[?/1] button to turn on the main power.
2. The message “VER X.XXX” is displayed. “X.XXX” is calcu-
lated by adding all firmware 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

signal
generator set
Procedure:
1. Turn on the set.
2. Input the following signal from signal generator to FM an-
tenna input directly.
Carrier frequency: A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation : 75 kHz
Modulation : 1 kHz
Note: Use 75 ohm coaxial cable to connect signal generator and the set.
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. Confirm that input frequency of A, B and C are detected and
automatic scanning stops.
When the station signal is received in good condition, automatic
scanning stops.
