4. CONTROLS

To prevent loose metal objects from getting into the CD
mechanism, make sure that the repair area is clean.
Before commissioning or servicing the device, the
two transport screws in the bottom can be removed.
These must be refitted after servicing.
The lens can be cleaned with a blower brush.
The CD mechanism is fitted with self-lubricating bearings and
must therefore NOT be lubricated.
Make sure that during repairs and measurements on the
side, the unit is not resting on the turntable motor shaft.
Do not loosen any screws other than those mentioned in the
hints.
The device consists of several MOS ICs. Because MOS ICs are
generally very sensitive to overload and overvoltage, the greatest
possible care must be taken during servicing. For further
instructions, see the package insert in the packaging of the ICs.
The CD must always rest properly on the turntable. For this
purpose, a plate pressure device is mounted in the lid. If a plate
has to be used for repairs to a boxed-out frame, use a separate
pusher. Code number of the pusher is 4822 532 60906.
Chip components are used in the device. For disassembling and
assembling chip components, see figures below.
The servo-µp can be placed in the service position to check the
switch and display board and also to test the servo systems
separately. (See Troubleshooting Method.)
The ERCO-IC, (Error Correction IC) which is supplied by
servicing, operates on a supply voltage of approx. 5V.
When an ERCO-IC is replaced, check the supply voltage.
If an extra PCB is mounted on the decoding PCB, remove
this PCB and make the connections as indicated in the
drawing of the decoding PCB.
The ICs used in the decoding circuit may have a different type
number than stated in the principal diagram.
DEMOD = SAA7010 = M429x
ERCO = SAA7020 = M428x
CIM = SAA7000 = M430x
FIL = SAA7030 = M455x
x is a digit from 0 - 9.
Service supports are provided for bottom settings that require the
unit to be in the normal operating position. Code number 4822
395 30202.
These supports can be fixed in the 4 holes of the frame.

•The LED holder consists of two parts which are attached to
each other with 4 locking tabs.
The upper part of the LED holder can be removed by bending
away the 4 locking tabs.
•The LED can be removed upwards from the PCB.
•When mounting, pay attention to the correct connection (anode
and cathode) and the height of the LED: To get the LED to the
correct height, it must be pushed against the top of the LED
holder before soldering.
Replacing the rotary table motor
•Take the frame out of the cabinet.
•Remove the preamplifier board which is attached to the CD
mechanism with four screws
•The turntable motor is attached to the chassis plate with 3
screws.
•When mounting, screw A must first be mounted (see Fig.).
ATTENTION: After assembly, the motor must be checked as
follows:
a. CD/Plate-light angle
b. Height adjustment of the turntable

THE LASER MECHANISM IS MUCH MORE SENSITIVE TO
STATIC CHARGE THAN A MOS IC.
CARELESS HANDLING DURING SERVICING CAN
DRASTICALLY REDUCE THE LIFETIME OF THE LASER.
THEREFORE, MAKE SURE THAT DURING THE SERVICE,
THE TOOLS AND YOURSELF HAVE THE SAME POTENTIAL
AS THE MECHANISM.
When one of the parts of the RAFOC unit is replaced, the angle
adjustment must be checked.
Remark:
The laser mechanism can contain both a laser diode that operates
at a positive supply voltage and a laser diode that operates at a
negative voltage.
THEY MUST NOT BE INTERCHANGED
When a laser diode is used which operates on a positive supply
voltage, the preamplifier board is provided with service printing
with the designation POS.VOLT.SH.
When using a laser diode that operates on a negative supply
voltage, the preamplifier board is provided with the service
printing with the designation NEG.VOLT PH.
Both the light pen and the preamplifier board are supplied for
service:
For negative supply voltage:
Light pen
Preamplifier Board (NEG.VOLT.PH.)
For positive supply voltage:
Light pen
Preamplifier Board (POS.VOLT.SH.)

MECHANICAL MEASUREMENTS AND SETTINGS
Height adjustment of the turntable (see Fig.)
6. MEASUREMENTS AND SETTINGS
This setting requires the device to be in normal operating mode.
Service supports 4822 395 30202 can be used for this
Play from CD 4822 397 30086 track 1 or (CD without defects).
Connect a DC voltmeter across resistor 3240 on the SERVO PCB.
(FOCUS MOTOR).
Loosen lock nut A. Use bolt B (Allen key) to adjust the turntable
height so that the voltage across 3240 is 0V ± 100mV. Retighten
lock nut A. When tightening, make sure that the voltage setting does
not change.
Checking the angle setting
Open the frame.
Place the mirror 4822 395 90205 on the focus unit and the glass
plate 4822 395 90204 (with pusher 4822 526 10241) on the
turntable.
Place the device under a light source, under which there is a straight
line (e.g. fluorescent with grille).
Place the RAFOC arm in the middle position. Turn the device so that
the RAFOC arm is parallel to the line under the light source (see
Fig.).
Look in the direction and in line with the line at its reflection on the
glass plate and mirror.
These lines should be no more than 4mm apart: Position the device
so that a line runs across the center of the mirror.
When the other line remains within the surface of the mirror, the
distance s is 4mm.
Turn the CD mechanism 90° from the previous position. The RAFOC
arm must remain in the middle position (see Fig.).
Repeat the previous measurement.
