WARNING
ESD
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.
GB
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 LIQUID LENS CLEANING
4
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. 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.
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

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.

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.

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.
good
The values from diode A-D should read 0±10mV. Diodes E and F are less critical.

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.
If one of the offsets is higher than ±10mV the CD drive has to be replaced. Otherwise replace the Signal Processor.
