4.2 Service Hints
4.2.1 DVD Module
This module can be repaired as follows:
1.
The VAL6011/14 is a combination of loading mechanism
and DVD-mechanism. Both the mechanism is not a
repairable unit and in case of failure it has to be replaced
with a new loader VAL6011/14.
Note: When replacing with a new VAL6011/14 two solder
joints have to be removed after connecting the OPU flex foil
to the board.
The solder joints which shortcircuits the laser diodes to
ground are for protection against ESD. Refer to Figure 4-5
and Figure 4-6 for location of solder points.

2. The mono board has to be repaired down to component
level. Repair handling of the monoboard requires a
workshop with sophisticated desoldering tools.
