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.

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.

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.

OPERATION CHECK WHEN THE LID IS OPENIn making an operation check with the MAIN Board removed fromthe set, short the SL894 (OPEN/CLOSE) of the MAIN Board withthe solder before starting the operation check.Note: Be sure to remove the solder used for shortcircuit after the repaire

completed.

SELF-DIAGNOSIS RESULT DISPLAY MODEThis set uses the self-diagnostic function system in which if an erroroccurred during the recording or playing, the mechanism controlblock and the power supply control block in the microcomputerdetect it and record its cause as history in the nonvolatile memory.By checking this history in the test mode, you can analyze a faultand determine its location.Total recording time is recorded as a guideline of how long theoptical pick-up has been used, and by comparing it with the totalrecording time at the time when an error occurred in the self-diagnosis result display mode, you can determine when the erroroccurred.Clear the total recording time, if the optical pick-up was replaced.

• All resistors are in Ω and 1/4 W or less unless otherwise

specified.• f : internal component.• C : panel designation.
