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.
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 viscous (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 infor-
mation.
Strictly follow the instructions whenever the components are re-
paired and/or replaced.
Notice pour composants spéciaux
Les composants identifiés par la marque 9contiennent des infor-
mations confidentielles.
Suivre scrupuleusement les instructions chaque fois qu’un com-
posant est remplacé et / ou réparé.
NOTE OF REPLACING THE IC3500 AND IC3501 ON
THE HDMI PC BOARD
IC3500 and IC3501 on the HDMI PC board cannot exchange with
single. When these parts on the HDMI PC board are damaged,
exchange the entire mounted board.
SAFETY CHECK-OUT (US MODEL)
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See

SPDIF UPDATE MODE
User plays the CD that contains u-com/DSP data with CD/DVD
player.
Update u-com/DSP etc. firmware from SPDIF input.
Connection:
CD/DVD
player
DIGITAL board
TV OPTICAL IN jack (IC2002)
set
* Procedure:
Normal case
1. While pressing [INPUT MODE] and [MUTING] button,
press the [?/1] button to turn on the main power.
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 TV OPTICAL IN jack (IC2002 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
also prohibited.
4. While main u-com is being updated, fluorescent indicator tube
is blacked out for few minutes.
5. When update data error is detected or disc is not matched with
target model, error messages “DISC ERR” and “PLAY. DISC”
are displayed to restart playing valid CD.
When flash writing error is happened, error messages “UPT.
ERR” and “PLAY. DISC” are displayed to restart playing CD.
6. When all update is finished, set is reboot automatically.
After reboot, complete message “COMPLETE” is displayed
(displayed 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 TV OPTICAL IN jack (IC2002 on the
DIGITAL board), and play update CD.
Update is started when DSP detect update signal. From this,
same as normal case.
VERSION CHECK
Function that displays the version number to check whether
SPDIF update is necessary or not.
* Procedure:
1. While pressing [INPUT MODE] and [DISPLAY] button,
press the [?/1] button to turn on the main power.
2. The message “VER X.XXX” is displayed. “X.XXX” is
calculated by adding all firmware version.
Example:
(MAIN ver. + DSP ver. + HDMI ver. + 7)/10 =
Displayed version
MAIN = 1.02, DSP = 1.01, HDMI = 1.00
↓
(1.02 + 1.01 + 1.00 + 1.03 + 7)/10 = 1.006
1.006 = X.XXX
SPDIF UPDATE TEST MODE
Function that checks hardware error for SPDIF update.
This test takes about 15 seconds.
* Procedure:
1. While pressing [INPUT MODE] and [DIMMER] buttons,

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
ANT input : 35 dBu (EMF)
Note:
Please use 75 ohm “coaxial cable” to connect SG and the set. You
cannot use video cable for checking.
Please use SG 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.
