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 electro-
static 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 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 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.

Procedure:
1.  Select 23.976Hz/1080p.
2.  Play “4.Motion picture”.
3.  Check whether player can play back or not.
4.  Check each outputs.
 Video:
 
Composite/S Video/component/HDMI.
 Audio:
 
Speaker out.
*  When 1080/24p monitor is nothing, 1080i (59.94Hz or 50Hz) 
can use instead of 1080/24p.
 
However this is temporary correspondence.
2. BLX-204
Procedure:
1.  Select 1080i (59.94Hz or 50Hz).
2.  Play “4.Motion picture”.
3.  Check whether player can play back or not (Check the picture 
and sound output).
3.  CD (HLX-A1)
Procedure:
Check whether player can play back or not (Check the sound out-
put).
4.  HLX-513/514 (NTSC), HLX-506/507 (PAL)
Procedure:
1.  After displayed Main Menu, select “1.Video Signal”.
2.  Play “1.Color bar 100%” (Check the picture and sound out-
put).
3.  Return to Menu.
4.  Play “Demonstration 4:3” or “Demonstration 16:9” (Check the 
picture and sound output).
NOTE  THE  IC101,  IC104,  IC105,  IC204,  IC205,  IC307,  
IC311,  IC501  AND  IC502  ON  THE  MB-134  BOARD  
REPLACING
IC101, IC104, IC105, IC204, IC205, IC307, IC311, IC501 and  
IC502 on the MB-134 board cannot exchange with single. When 
these parts are damaged, exchange the entire mounted board.
RELEASING  THE  DISC  TRAY  LOCK
The disc tray lock function for the antitheft of an demonstration 
disc in the store is equipped.
Releasing Procedure:
1.  Press the [
?/1
] button to turn on the system.
2.  Press the [FUNCTION] button to select “BD/DVD”.
3.  Press the [
x
] and [
Z
] buttons simultaneously and hold down 
unit “DEMO OFF” displayed on the fluorescent indicator tube 
(around 5 seconds).
Note: When “DEMO ON” is displayed, the disc tray lock is not released 
by turning power on/off with the [?/1] button.
ABOUT  THE  LENS  CLEANING
Do not do the lens cleaning with the cotton bud etc. It causes the 
trouble.

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.
