15、 Dirt on lens The laser lens must never be touched ! Refer to “Optical Disc Reference Book” for full description. The “Optical Disc Reference Book” is available in the following languages: English (Part no. 3540685), German (Part no. 3540686), French (Part no. 3540687), Danish (Part no. 3540688), It

Pixel error or frozen picture is typically due to DVD mechanism failure. Repair Tips, English Summary from Optical Disc Reference Book Optical unit The optic

17、al unit, also called the OPU - Optical Pick-Up Unit - with actuator, laser optics and belonging electronics is the single most expensive and delicate part of the DVD mechanism. It is especially the OPU which must be protected against unintentional contact, dust or other pollution during storage, tra

18、nsport, production and service. Furthermore, special care must be taken to prevent ElectroStatic Discharge (ESD). The laser lens must never be touched! The actuator (the motion mechanism for the lens/mirror system) has together with the complete OPU been adjusted by the supplier. The adjustment is f

19、ixed and is not supposed to be readjusted. Please also take note that the actuator includes magnets which may attract iron particles from screw-cuttings etc. and this may detriment the function of the actuator. Furthermore, please avoid that other magnets, in for instance loudspeakers or magnetic sc

20、rew drivers get into close contact with the OPU. The OPU which has been adjusted individually together with the mechanism itself cannot be readjusted, repaired or replaced. Cleaning and test of the OPU Because of the design of the lens it can be very difficult to determine whether the lens is dirty,

21、 therefore always clean the lens when servicing. A finger print on the lens will, like dust and other contaminants affect the performance of the lens negatively. If a contamination has taken place the lens can be cleaned with care. Loose particles usually can be removed with air (use e.g. a blower b

22、rush for camera lenses). Finger prints etc. can be removed with a special cleaning fluid - “Kodak Lens Cleaner CAT 176 71 36” - on a cotton bud (e.g. of the ESD safe wooden type). Clean the lens by dipping the cotton bud “Kodak Lens Cleaner CAT 176 71 36” and carefully wipe it with circular movement

23、s. Remove the moisture on the lens with the dry end of the cotton bud. 1.61.7 No picture DVD mechanism failure DVD main board failure AV Board failure Power supply failure Refer to wiring diagram for point of measurement. 1.
