SECTION 1
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 fl exible 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 refl ective surface by the objective lens in the optical
pickup 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 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 viscous (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.
RELEASING THE DISC SLOT LOCK
The disc slot lock function for the antitheft of an demonstration
disc in the store is equipped.
Releasing Procedure:
1. Press the [
2. Press the [HOME] button on the remote commander to enter

NOTE OF REPLACING THE IC101 AND IC501 ON
THE MB-149 BOARD
IC101 and IC501 on the MB-149 board cannot exchange with
single. When these parts are damaged, exchange the complete
mounted board.
NOTE OF REPLACING THE IC102, IC103, IC202 AND
IC203 ON THE MB-149 BOARD
Replacement of IC102, IC103, IC202 and IC203 on the MB-149
board used in this unit requires a special tool.
NOTE OF REPLACING THE TOUCH BOARD
When the TOUCH board is defective, exchange the complete
mounted board.

* When 1080/24p monitor is nothing, 1080i (59.94Hz or 50Hz)
can use instead of 1080/24p.
However this is temporary correspondence.
* When the output of HDMI is 1080p/1080i/720p, the signal of

NOTE OF REPLACING THE OPTICAL DEVICE (KEM480AAA) OR MB-149 BOARD
The password will be supplied to only service HQ, and
service center name, q’ty and all of software registered
information should be maintained by service HQ, and
Audio will ask to report the registration information.
Optical device (KEM-480AAA) for BD requires precise read out
functions and secure contents protection system for more than past
DVD/CD.
Therefore, in the case repaired as follows, the writing work of the
OP data is necessary.
• When the optical device (KEM-480AAA) is replaced (The
MB-149 board doesn’t replace).
• When both the optical device (KEM-480AAA) and MB-149
board are replaced.
• When the MB-149 board is replaced (The optical device
(KEM-480AAA) doesn’t replace) (In this case, do the work of
“3. Optical device (KEM-480AAA) replacement” other than
the replacement of new optical device).
Note: The servo adjustment is done while writing the OP data. The manual
adjustment is unnecessary.
LD ON TIME history doesn’t carry over.
Do not touch any optical block parts, turn table and during replac-
ing. BD laser diode is very sensitive.
1. Preparation
1-1. ESD Countermeasure
It is necessary to confi rm the state of static electricity in the work
space before the repair is started.
The static electricity resistance of the BD laser is weaker than that
of the DVD/CD laser.
Do work space and worker’s ESD countermeasures to prevent destruction by ESD.
1-2. Jig
• Digital camera (Recommend with macro mode)
• USB memory
• PC
• Barcode decoder (Refer to “1-3. Barcode decoder
(BDPRdec)”)
1-3. Barcode decoder (BDPRdec)
Jig name: BDPRdec.exe
Software contents:
• BDPRdec.exe : Barcode decoder software
• SavePath.ini : Decoded fi le destination setting fi le (Ini-
tial destination is “C:\BuData.txt”)
• TasmanBars.dll : Decode dll
• Uninst.exe : Uninstall the “BDPRdec.exe” from PC
Note: When working by OS of the version after VISTA, it is necessary
to change destination of the decoded fi le to save by UAC function
(user account function).
In that case, change the description in “SavePath.ini” (default de-
scription is “C:\BuData.txt”) other than C drive.
Install procedure:
1. Unzip the barcode decoder fi les to any PC folder.
2. Check the attached 2D code photo (OK_sample.JPG) drag &
drop onto “BDBUDec.exe”.
When the barcode decoder is used for the fi rst time, the pass-
word is necessary. It is unnecessary since the second times.
Note 1: The password will be supplied to only service headquarters, and
service center name/q’ty/all of software registered information
should be maintained by service headquarters.
Note 2: Do not change the decoded fi le name “BuData.txt”.
