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.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C
during repairing.
•Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
•Be careful not to apply force on the conductor when soldering
or unsoldering.
CAUTION
Use of controls or adjustments or performance of procedures
otherthanthosespecifiedherein may result in hazardous radiation
exposure.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety check before releasing the set to the customer:
Check the antenna terminals, metaltrim, “metallized” knobs, screws,
and all other exposed metal parts forAC 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-operatedAC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOMor battery-operatedACvoltmeter.The “limit” indication
is 0.75V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passiveVOM that is suitable. Nearly all battery operated
digital multimeters that have a 2VAC range are suitable. (See

About Multi Session CD
•This system can play Multi Session CDs when
an MP3 audio track is contained in the first
session. Any subsequent MP3 audio tracks
recorded in later sessions can also be played
back.
•This system can play Multi Session CDs when
a JPEG image file is contained in the first
session. Any subsequent JPEG image files
recorded in later sessions can also be played
back.
•If audio tracks and images in music CD format
or video CD format are recorded in the first
session, only the first session will be played
back.
About the Super Audio CD
Super Audio CD is a new high-quality audio
disc standard where music is recorded in the
DSD (Direct Stream Digital) format
(conventional CDs are recorded in the PCM
format). The DSD format, using a sampling
frequency 64 times higher than that of a
conventional CD, and with 1-bit quantization,
achieves both a wide frequency range and a wide
dynamic range across the audible frequency
range, and so provides music reproduction
extremely faithful to the original sound.
Types of Super Audio CDs
There are two types of discs, depending on the
Super Audio CD layer and CD layer
combination.
•
•
Super Audio CD layer: A high-density
signal layer for Super Audio CD
CD layer*
1
: A layer that is readable by a
conventional CD player
*1You can play the CD layer on a conventional CD
player.
*2Since both layers are on one side, it is not necessary
to turn the disc over.
*3To select a layer, see “Selecting a Playback layer for
a Super Audio CD”.
Region code
Your system has a region code printed on the
back of theunitand will onlyplayDVDslabeled
with the same region code.
DVD VIDEOs labeled will also play on this
system.
If you try to play any other DVD VIDEO, the
message [Playback prohibited by area
limitations.] will appear on the TV screen.
Depending on theDVD VIDEO, no region code
indication may be giveneventhoughplayingthe
DVD VIDEO is prohibited by area restrictions.
Note on playback operations
of DVDs and VIDEO CDs
Someplayback operationsof DVDs andVIDEO
CDs may be intentionally set by software
producers. Since this system plays DVDs and
VIDEO CDs according to the disc contents the
software producers designed, some playback
features may not be available. Also, refer to the
instructions supplied with the DVDs or VIDEO
CDs.

SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
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.
RELEASING THE DISC TRAY LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Releasing Procedure :
Press two buttons of Zand xsimultaneously for five seconds.
The message “UNLOCKED” is displayed and the tray is unlocked.
Note: When“LOCKED” isdisplayed, thetray lock is not releasedby turning
power on/off with the I/1button.
NOTE OF REPLACING THE DMB10 BOARD
New part of EEPROM (IC103) on the DMB10 board cannot be
used.Therefore, if the mounted DMB10 board is replaced, exchange
new EEPROM with that used before the replacement.
RELEASING THE DEMO PLAY LOCK
Releasing Procedure:
Press two buttons of Nand x.
The message “DEMO OFF”.
NOTE OF HANDLING THE MIB01 BOARD (Part No. A-
1124-106-A)
When the MIB01 board is replaced by a repair for a fee, throw
away the MIB01 board after obtaining consent of not returning of
the MIB01 board to the customer. When throwing away the MIB01
