2. Safety Instructions, Warnings and Notes2.1 Safety Instructions
2.1.1 General Safety
Safety regulations require that during a repair: Connect the unit to the mains via an isolation transformer. Replace safety components, indicated by the symbol ,
only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, you must return the unit in its original condition. Pay, in particular, attention to the following points: Route the wires/cables correctly, and fix them with the
mounted cable clamps. Check the insulation of the mains lead for external
damage. Check the electrical DC resistance between the mains plug
and the secondary side:1. Unplug the mains cord, and connect a wire between
the two pins of the mains plug.2. Set the mains switch to the 'on' position (keep the
mains cord unplugged!).3. Measure the resistance value between the mains plug
and the front panel, controls, and chassis bottom. 4. Repair or correct unit when the resistance
measurement is less than 1 M. 5. Verify this, before you return the unit to the customer/
user (ref. UL-standard no. 1492).6. Switch the unit off, and remove the wire between the
two pins of the mains plug.
2.1.2 Laser Safety
This unit employs a laser. Only qualified service personnel may remove the cover, or attempt to service this device (due to possible eye injury).
Laser Device UnitType : Semiconductor laser
GaAlAsWavelength : 650 nm (DVD)
: 780 nm (VCD/CD)Output Power : 20 mW (DVD+RW
writing): 0.8 mW (DVD
reading): 0.3 mW (VCD/CD
reading)Beam divergence : 60 degree
Figure 2-1 Class 1 Laser Product
Note: Use of controls or adjustments or performance of procedure other than those specified herein, may result in hazardous radiation exposure. Avoid direct exposure to beam.
2.2 Warnings
2.2.1 General
All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD, symbol ). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are at the same potential as the mass of the set by a wristband with resistance. Keep components and tools at this same potential. Available ESD protection equipment: Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822 310 10671.
Wristband tester 4822 344 13999. Be careful during measurements in the live voltage section.
The primary side of the power supply (pos. 1005), including the heatsink, carries live mains voltage when you connect the player to the mains (even when the player is 'off'!). It is possible to touch copper tracks and/or components in this unshielded primary area, when you service the player. Service personnel must take precautions to prevent touching this area or components in this area. A 'lightning stroke' and a stripe-marked printing on the printed wiring board, indicate the primary side of the power supply.
Never replace modules, or components, while the unit is on.
2.2.2 Laser
The use of optical instruments with this product, will increase eye hazard.
Only qualified service personnel may remove the cover or attempt to service this device, due to possible eye injury.
Repair handling should take place as much as possible with a disc loaded inside the player.

4. Mechanical InstructionsNote that exploded views can be found in chapter 10
4.1 General
Follow the dismantling instructions in described order.Do not place the unit with its PWB on a hard surface (e.g. table), as it could damage the components on it.Always place something soft (a towel or foam cushion) under it.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, clamp)2. PWB (or 'mono board')3. DVD-Module (OPU, turntable motor, and sledge-motor
assy)4. Encasing
Figure 4-1 Basic Engine dismantling (part1)
4.3 Cabinet and Clamper Bridge
Remove the encasing by releasing the four screws [1], 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)!
Remove the clamper bridge assy, by releasing the two screws [1], see figure 4-2

4.4 Tray
Remove encasing as as described in 4.3 Disengage the two holders that fix the tray [1], see figure 4-
3, and pull out the tray [2]
Figure 4-3 Remove Tray
4.5 Printed Board
Note: After Exchanging the PWB (or the DVD-M) the complete drive has to be adjusted! Refer to chapter 8 for adjustment instructions! Remove encasing and clamper bridge as described in 4.3 Disconnect the four flex foils from the PWB connectors Remove the 2 screws that hold the PWB, see figure 4-4 At assembly make sure that the 5 heat paths (gray rubber
pieces) are placed on the ICs!
Figure 4-4 Remove PWB
4.6 DVD-M
Caution: Never try to align or repair the DVD-Module itself! Only the factory can do this properly. Service engineers are only allowed to exchange the sledge motor assy.After Exchanging the DVD-M (or the PWB) the complete drive has to be adjusted! Refer to chapter 8 for adjustment instructions! Remove encasing, clamper bridge and PWB as described
in 4-3 and 4-5 Remove the four screws [1], see figure 4-5. Now you can remove the DVDM

4.7 Sledge Motor Assembly
Caution: Never try to align or repair the DVD-Module itself! Only the factory can do this properly. Service engineers are only allowed to exchange the sledge motor assy. Place the DVD-Module, with the laser facing downwards
on a soft surface. Remove the three screws that hold the sledge-motor assy
and lift the assy upwards. You can replace it now.
Figure 4-6 Remove Sledge Motor Assy
4.8 Re-assembly
To re-assemble the module, do all processes in reverse order.Take care of the following: Sledge-motor assy: Mesh the teeth of the sledge motor
and sledge rack properly, during mounting of the sledge motor assy.
Heat Paths: Put the 5 heat paths (gray rubber pieces) back to their position on the ICs, see figure 4-7.
Complete module: Place all wires/cables in their original positions
Emergency opening slot: Be sure that the slot for the emergency tray opener is covered by adhesive tape!
Jumper selection: Jumper has to be in position "Master"!
