SERVICE AIDS
GB WARNING
All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.

Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used
Safety components are marked by the symbol !.

PLAYABILITY CHECK
For sets which are compatible with CD-RW discs
use CD-RW Printed Audio Disc....................7104 099 96611
TR 3 (Fingerprint)
TR 8 (600µ Black dot) maximum at 01:00
• playback of these two tracks without audible disturbance
playing time for: Fingerprint ≥10seconds
Black dot from 00:50 to 01:10
• jump forward/backward (search) within a reasonable time
For all other sets
use CD-DA SBC 444A..................................4822 397 30245
TR 14 (600µ Black dot) maximum at 01:15
TR 19 (Fingerprint)
TR 10 (1000µ wedge)
• playback of all these tracks without audible disturbance
playing time for: 1000µ wedge ≥10seconds
Fingerprint ≥10seconds
Black dot from 01:05 to 01:25
• jump forward/backward (search) within a reasonable time
2
CUSTOMER INFORMATION
It is proposed to add an addendum sheet to the set which
informs the customer that the set has been checked
carefully - but no fault was found.
The problem was obviously caused by a scratched, dirty or
copy-protected CD. In case problems remain, the customer
is requested to contact the workshop directly.
The lens cleaning (method 3) should be mentioned in the
addendum sheet.
The final wording in national language as well as the printing
is under responsibility of the Regional Service Organizations.
3
FAST LENS CLEANING (dry brush)
Use lens cleaning CD
SBC AC300...........................................9082 100 00043
Insert the lens cleaning CD, press PLAY and follow the
voice guide´s instructions on the CD.
4
LIQUID LENS CLEANING
Because the material of the lens is synthetic and coated
with a special anti-reflectivity layer, cleaning must be done
with a non-aggressive cleaning fluid. It is advised to use
“Cleaning Solvent B4-No2”, available with codenumber
4822 389 10026.
The actuator is a very precise mechanical component and
may not be damaged in order to guarantee its full function.
Clean the lens gently (don’t press too hard) with a soft and
clean cotton bud moistened with the special lens cleaner.
The direction of cleaning must be in the way as indicated in
the picture below.
Before touching the lens it is advised to clean the
surface of the lens by blowing clean air over it.
This to avoid that little particles make scratches on
the lens.

EYE-PATTERN SIGNAL – JITTER MEASUREMENT
Measure the signal on the input of the Signal processor
using an analog oscilloscope. Please find the exact
measuring point in your Service Manual.
See below examples of the signal. Amplitude should read at
least 700mVpp using SBC444A.
good
bad
If the oscilloscope shows a signal like the ‘bad’ one, and/or
the amplitude decreases within 1 minute - the CD drive has
to be replaced.
6
CD DRIVE – LASER CURRENT MEASUREMENT
The laser current can be measured as a voltage drop on a
resistor. The resistor is marked in every Service Manual.
The value depends on the type of CD drive.
typical value most probably defect
VAMxxxx : 150-230mV ≥350mV
MCDxx : 170-230mV ≥300mV
DA1x : 210-250mV ≥350mV
DA2x : 175-200mV ≥250mV
Use SBC444A (CD-DA) for measurement.
7
CD DRIVE – OFFSET MEASUREMENT
The photodiodes of the CD-drive may have an offset. These
offsets have to be compensated by the signal processor.
High offsets can lead to poor playability of some CDs
(skipping tracks).
To measure the offset values, start the Service Test
Program - section “Focus Test” without a CD.
The offsets can be measured with a DC Millivoltmeter
directly on the connector (see drawing below). Pin
numbering varies from drive to drive.
The values from diode A-D should read 0±10mV.
Diodes E and F are less critical.
If one of the offsets is higher than ±10mV the CD drive has
to be replaced. Otherwise replace the Signal Processor.
