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

12、 this potential.

17、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 n

18、ational language as well as the printing is under responsibility of the Regional Service Organizations. 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

19、 use “Cleaning Solvent 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 wa

20、y 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. INSTRUCTIONS ON CD PLAYABILITY 2 - 2 3-1 3-1 SET BLOCK DIAGRAM FUNCTION IC TDA7468D CD SERVO BU95
