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.

CLASS 1

GBSafety regulations require that the set be restored to its original

condition and that parts which are identical with those specified,

be used

For all other sets

use CD-DA SBC 444A..................................4822 397 30245

TR 14 (600 Black dot) maximum at 01:15

TR 19 (Fingerprint)

TR 10 (1000 wedge)

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.
