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 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.
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 electrostaticbreakdown because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic breakdown and also usethe procedure in the printed matter which is included in the repairparts.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 more than 30 cm away from the objective lens.
CHUCK PLATE JIG ON REPAIRINGOn repairing CD section, playing a disc without the CD lid, useChuck Plate Jig.
• Code number of Chuck Plate Jig : X-4918-255-1
LASER DIODE AND FOCUS SEARCH OPERATIONCHECK
1. Turn ON the [OPERATE] button and press [CD] button to CDposition.
2. Open the CD lid.3. Turn on S801 with screwdriver, etc. as following figure.4. Press the u (CD) button.5. Confirm the laser diode emission while observing the objecting
lens. When there is no emission, Auto Power Control circuitor Optical Pick-up is broken.Objective lens moves up and down three times for focus search.
S801
SAFETY CHECK-OUTAfter correcting the original service problem, perform the followingsafety check before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs, screws,and all other exposed metal parts for AC leakage.Check leakage as described below.
LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microamperes.).Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers’ instructions to use theseinstruments.
2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examplesof a passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2 V AC range are suitable. (SeeFig. A)
