SERVICE HINTS
●
Power Supply Unit
The power supply unit has to be replaced in case of
failure. The schematic provided in the manual is only for
information and no service parts will be available.
●
DVD Mechanism
1. The DVD mechanism is not a repairable unit and in
case of failure, it has to be replaced with a new DVD
mechanism.
Note: When replacing with a new DVD mechanism, two
solder joints have to be removed after connecting the
OPU flex foil to the mono board.
The solder joints, which shortcircuits the laser diodes to
ground, are for protection against ESD. Refer to Fig. 1
and 2 for location of solder joints.
2. The mono board has to be repaired down to component
level. Repair handling of the monoboard requires a
workshop with sophisticated desoldering tools.
