Safety Instructions, Warnings and Notes

2. Safety Instructions, Warnings and Notes

EN 3VAD 8031 2.

2.1 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 MΩ.

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).

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.

• Text below is placed inside the unit, on the laser cover
shield:

Note 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

4.3 Cab inet 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

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"!
