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.

Note: Refer to “2-12. OPTICAL DEVICE (KEM-460AAA), WIRE (FLAT TYPE)” (page 17) 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 rear USB connector on this set, 

and turn the power on.

7.  Press the [FUNCTION] button to select “BD/DVD”.
8.  Press the buttons on the remote commander in order of 

[RETURN], [0], [2], [1], [SUBTITLE], and enter the service 
mode.

9.  Press the buttons on the remote commander in order of [8], [1], 

[ENTER], and execute “[1] Drive OP data Write”.

10. Turn the power off after writing the OP data.

13. Confi rm value is the following specifi cation value, and turn the 

power off.

 Specifi cation value:
 

BD 

: 6 mA
