CAPACITOR ELECTRICAL DISCHARGE PROCESSING
When checking the board, the electrical discharge is necessary for
the electric shock prevention.
Connect the resistors referring to the
fi
gure below.

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
• When the MB-134 board is replaced (The optical device
The servo adjustment is done while writing the OP data. The manual
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 con
fi
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)”)
