SERVICE AIDS
GB WARNINGAll ICs and many o ther 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.

GBSafety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used

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 (method3) 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.
3FAST LENS CLEANING (dry b rush)
Use lens cleaning CD
SBC AC300...........................................9082 100 00043
Insert the lens cleaning CD, press PLAY and follow the
voice guides instructions on the CD.
4LIQUID LENS CLEANING
Because the material of the lens is synthetic and coated
with a special anti-reflectivity layer, cleaning must be donewith 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 (dont 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 c lean air over it.
This to avoid t hat little particles make scratches on
the lens.

5EYE-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.
6CD 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.
7CD 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 Mill ivoltmeter
directly on the connector (see drawing below). Pin
numbering varies from drive to drive.
The values from diode A-D should read 010mV.
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.
