15、者资料库 4 XP-ZR850 SECTION 1 SERVICING NOTES NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. Du

16、ring repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as

17、to be focused on the disc reflective surface by the objective lens in the optical pick- up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK During normal operation of the equipment, emiss

18、ion of the laser diode is prohibited unless the upper lid is closed while turning ON the S531. (push switch type) The following checking method for the laser diode is operable. Method: Emission of the laser diode is visually checked. 1. Open the upper lid. 2. With a disc not set, turn on the S531 wi

19、th a screwdriver having a thin tip as shown in Fig.1. 3. Press the u ENTER button. 4. Observing the objective lens, check that the laser diode emits light. When the laser diode does not emit light, automatic power control circuit or optical pick-up is faulty. In this operation, the objective lens wi

20、ll move up and down 2 times along with inward motion for the focus search. NOTES ON REPLACEMENT OF EGL BOARD OR EEPROM (IC1602) When EGL board is replaced or EEPROM (IC1602) on the EGL board is replaced, patch processing is needed. Confirm about information of patch processing to each service headqu

(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FRE

22、E MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulat

23、or should be set to about 350 C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such

24、as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. OPERATION CHECK WHEN THE LID IS OPEN In performing the repair with the power supplied to the set, removing the JACK board causes the set to be disabled. In

25、 such a case, make a solder bridge to short SL501 (OPEN) on the JACK board in advance.
