4.1 General
Follow the dismantling instructions in described order.
Never touch the lens of the OPU.
Take sufficient ESD measures during handling.
4.2 Dismantling
You can divide the Basic Engine into the following parts:
1. Loader (frame and tray)
2. PWB
3. DVD-Mechanism (OPU, traverse with turntable motor and
sledge-motor assy)
4. Encasing
4.3 Cabinet
– Remove the encasing by releasing the four screws at the
underside of the drive, see figure 4-1
– Make sure that you do not lose the 5 heat paths (gray
rubber pieces that conduct the heat from the ICs to the
case)!
– If you need to measure on the PCB while a disc is inserted,
the top case should be applied again onto the drive. In this
way the clamping mechanism is established.
