jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.

Precautions
1-4 Special Precautions and Warning Labels for Laser Products (Continued)
1-4-1 Warnings 1. When servicing, do not approach the LASER exit with the eye too closely. In case it is necessary to confirm LASER beam emission, be sure to observe from a distance of more than 30 cm from the surface of the objective lens on the optical pick-up block. 2. Do not attempt to handle the objective lens when the DISC is not on the tray. 1-4-2 Laser Diode Specifications Material: GaAs+ GaAlAs Wavelength: 760-800 nm Emission Duration: Continuous Laser Output: 0.2 mw (measured at a 1.6 mm distance from the objective lens surface on the optical pick-up block.) 1-4-3 Handling the Optical Pick-up 1. Static electricity from clothing or the body may cause electrostatic breakdown of the laser diode in the Optical Pickup. Follow this procedure: 2. Place a conductive sheet on the work bench (i.e., the black sheet used for wrapping repair parts.) Note: The surface of the work bench should be covered by a copper ground plane, which is grounded. 3. The repair technician must wear a wrist strap which is grounded to the copper sheet. 4. To remove the Optical Pickup block: Place the set on the conductive sheet, and momentarily touch the conductive sheet with both hands. (While working, do not allow any electrostatic sources--such as clothes--to touch the unit.) 5. Ground the "Short Terminal" (located on the PCB, inside the Pickup Assembly) before replacing the Pickup. This terminal should be shorted whenever the Pickup Assembly is lifted or moved. 6. After replacing the Pickup, reopen the Short Terminal. See diagrams below:
