    Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be

    damaged by heat.

    Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C

    during repairing. Do not touch the soldering iron on the same conductor of the

    circuit board (within 3 times). Be careful not to apply force on the conductor when soldering

    or unsoldering.

    This appliance is classified as a CLASS 1 LASER product.This marking is located on the rear exterior.

    CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.

    UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed with

    the lead free mark due to their particular size)

    : LEAD FREE MARKUnleaded solder has the following characteristics.

    Unleaded solder melts at a temperature about 40 C higherthan ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 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 bridgesoccur such as on IC pins, etc.

    Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

    SAFETY-RELATED COMPONENT WARNING!!COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINEWITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSEPART NUMBERS APPEAR AS SHOWN IN THIS MANUAL ORIN SUPPLEMENTS PUBLISHED BY SONY.

    SERVICING NOTES

    NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

    The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.

    NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe 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 OPERATIONCHECKCarry out the S curve check in CD section adjustment and checkthat the S curve waveforms is output three times.

    ELECTRICAL ADJUSTMENTSCD SECTION

    Note:1. CD Block is basically designed to operate without adjustment.

    Therefore, check each item in order given.2. Use YEDS-18 (3-702-101-01) unless otherwise indicated.3. Use an oscilloscope with more than 10M impedance.4. Clean the object lens by an applicator with neutral detergent when the

    signal level is low than specified value with the following checks. Abbreviation

    MX: Mexican model

    S-CURVE CHECK

    Procedure:1. Connect an oscilloscope to TP (FE) and TP (VC) on the CD

    board (except MX) or BD board (MX).2. Press the I/1 button to turn the power on.3. Load the disc (YEDS-18) and actuate the focus search. (In

    consequence of open and close the disc tray, actuate the focussearch)

    4. Confirm that the oscilloscope waveform (S-curve) issymmetrical between A and B. And confirm peak to peak levelwithin 3 0.5 Vp-p.

    Note: Try to measure several times to make sure than the ratio of A : Bor B : A is more than 10 : 7.

    Take sweep time as long as possible and light up the brightnessto obtain best waveform.

    Connecting Location: CD board (except MX)BD board (MX)

    RFAC LEVEL CHECK

    Procedure:1. Connect an oscilloscope to TP (RFACO) and TP (VC) on the

    CD board (except MX) or BD board (MX).2. Press the I/1 button to turn the power on.3. Load the disc (YEDS-18) and playback.4. Confirm that oscilloscope waveform is clear and check if RFAC

    signal level is correct or not.Note: Clear RFAC signal waveform means that the shape can be clearly

    distinguished at the center of the waveform.
