PRECAUTIONS FOR CHECKING LASER DIODE EMISSION 5-4. HOW TO IDENTIFY OPTICAL PICK-UP KMS262A/KMS-262E To check the emission of the laser diode during adjustments, never view directly from the top as this may lose your eye-sight. This set uses optical pick-up KMS-262E in the production, but for the repair, only the KMS-262A is supplied. As a result, two types of optical pick-ups are used for this set, and the specified values for the check and adjustment of the laser power vary depending on the type. Therefore, in performing the check and adjustment of the laser power, first make sure the type of optical pick-up. The type of optical pick-up can be identified as follows. 5-3. PRECAUTIONS FOR USE OF OPTICAL PICKUP (KMS-262A/262E) As the laser diode in the optical pick-up is easily damaged by static electricity, solder the laser tap of the flexible board when using it. Before disconnecting the connector, desolder first. Before connecting the connector, be careful not to remove the solder. Also take adequate measures to prevent damage by static electricity. Handle the flexible board with care as it breaks easily. pick-up – KMS-262A – – KMS-262E – [Top view] [Top view] [Side view] [Side view] flexible board laser tap Optical pick-up flexible board TYPE2 VR (small) 26 TYPE3 VR (large) MDS-NT1 5-5. PRECAUTIONS FOR ADJUSTMENTS 1. When replacing the following parts, perform the adjustments and checks with in the order shown in the following table. 2. Set the test mode when performing adjustments. After completing the adjustments, exit the test mode. Perform the adjustments and checks in “group Service” of the test mode. 3. Perform the adjustments to be needed in the order shown. 4. Use the following tools and measuring devices. • Check Disc (MD) TDYS-1 (Part No. : 4-963-646-01) • Test Disk (MDW-74/GA-1) (Part No. : 4-229-747-01) • Laser power meter LPM-8001 (Part No. : J-2501-046-A) or MD Laser power meter 8010S (Part No. : J-2501-145-A)*1 • Oscilloscope (Measure after performing CAL of prove) • Digital voltmeter • Thermometer • Jig for checking BD board waveform (Part No. : J-2501-149-A) • Attached software “OpenMG Jukebox” (Part No. : 4-237-880-01) • Software for test mode (Distributed together with the Service Manual) • Attached USB cable (Part No. : 1-757-471-11) • Personal computer (Refer to Servicing Notes) 5. When observing several signals on the oscilloscope, etc., make sure that VC and ground do not connect inside the oscilloscope. (VC and ground will become short-circuited) 6. Using the above jig enables the waveform to be checked without the need to solder. (Refer to Servicing Note on page 8) 7. As the disc used will affect the adjustment results, make sure that no dusts nor fingerprints are attached to it. 8. In normal operation check after the completion of adjustment, be sure to perform the recording check (check in, check out) using the software “OpenMG Jukebox” attached. *1 Laser power meter When performing laser power checks and adjustment (electrical adjustment), use of the new MD laser power meter 8010S (Part No. : J-2501-145-A) instead of the conventional laser power meter is convenient. It sharply reduces the time and trouble to set the laser power meter sensor onto the objective lens of optical pick-up.
