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.
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).
“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 de-
struction by ESD.
