NOTE  OF  REPLACING  THE  OPTICAL  DEVICE (KEM-
460AAA)  OR  MB-134  BOARD
Optical device (KEM-460AAA) 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-460AAA) is replaced (The 

MB-134 board doesn’t replace).

•  When both the optical device (KEM-460AAA) and MB-134 

board are replaced.

•  When the MB-134 board is replaced (The optical device  

(KEM-460AAA) doesn’t replace) (In this case, do the work of 
“3. Optical device (KEM-460AAA) 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 de-
struction by ESD.

1-2. Jig
•  Digital camera (Recommend with macro mode)
• USB 

memory

• PC
•  Barcode decoder (Refer to “1-3. Barcode decoder 

(BDBUDEC)”)

2.  Pass-fail judgment of the optical device (KEM-460AAA)
Perform pass-fail judgment to judge whether the repair of the optical device (KEM-460AAA) is necessary.

2 : 12 V

6 : 5 V

Note: Refer to “2-17. OPTICAL DEVICE (KEM-460AAA)” (page 22) about how to remove the FFC HOLDER (REAR).

Note: The photo in fl ow is an image.

Procedure:
1.  Remove the INSULATOR (4 pieces) and broken optical de-

vice (KEM-460AAA) from LOADING ASSY.

2.  Take photo of the barcode on new optical device (KEM-

460AAA) bottom side by digital camera.

3.  Assemble the INSULATOR (4 pieces) to new optical device 

(KEM-460AAA),  fi x (Torque value: 2 kgf) it to LOADING 
ASSY with screw, and assemble this set.

4.  Drag & drop the taken photo by step 2 to “BDBUDec.exe”, 

and make the text data (File name: BuData.txt).

5.  Save the text data to USB memory.
6.  Connect USB memory with right USB connector on this set, 

and turn the power on.

NOTE  OF  REPLACING  THE  IC300  AND  IC302  ON  
THE  AMP  BOARD  AND  THE  COMPLETE  AMP  BOARD
When IC300 and IC302 on the AMP board and the complete AMP 
board are replaced, it is necessary to spread the compound (OIL 
COMPOUND (G777)) (Part No. J-2501-335-A ) between parts 
and heat sink.
Spread the compound referring to the fi gure below.

NOTE  WHEN  VOLTAGE  ON  THE  AMP  BOARD  IS  
MEASURED
Do the following work when you measure the voltage of the AMP 
board.

Procedure:
1.  Remove the FAN motor (M301, 302).
2.  Be short-circuited of SL192 on the AMP board.

Note: The set enters the state of protect when SL192 is not short-circuited.
 

  Moreover, the set enters the state of protecting when the motor is 

not detached with SL192 short-circuited.

3.  Measure the voltage of the AMP board.
4.  Remove solder on SL192 after the measurement ends.
5.  Assemble the FAN motor (M301, 302).

NOTE  OF  DISC  PLAYBACK  IN  DISASSEMBLED  STATE
Reproduce by setting up the BD drive without fail in the vertical 
direction (the same direction as the state of the set) when you re-
produce the disc with the set taken apart.
There is a possibility that the disc is not correctly reproduced when 
setting it up in a wrong direction (horizontal direction etc.).
