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.

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 performing the repair with the power supplied to the set, removingthe MAIN board causes the set to be disabled.In such a case, make a solder bridge to short SL894 (OPEN/CLOSE)on the MAIN board in advance.

• Note For Printed Wiring Boards and Schematic Diagrams

• Main board is multi-layer printed board.However, the patterns of intermediate-layer have not been in-cluded in this diagrams.

• Lead Layouts

Note on Schematic Diagram:• All capacitors are in µF unless otherwise noted. (p: pF)

50 WV or less are not indicated except for electrolyticsand tantalums.

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

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

• A : B+ Line.• Total current is measured with MD installed.• Power voltage is dc 1.5 V and fed with regulated dc power

supply from battery terminal.• Voltages and waveforms are dc with respect to ground in

playback mode.no mark : PLAYBACK

• Voltages are taken with a VOM (Input impedance 10 MΩ).Voltage variations may be noted due to normal produc-tion tolerances.

• Waveforms are taken with a oscilloscope.Voltage variations may be noted due to normal produc-tion tolerances.

• Circled numbers refer to waveforms.• Signal path.E : PLAYBACKj : RECF : USB CHECK OUTf : USB CHECK IN

• AbbreviationCND : Canadian model

Note on Printed Wiring Board:• X : parts extracted from the component side.• Y : parts extracted from the conductor side.• : Pattern from the side which enables seeing.(The other layers' patterns are not indicated.)

Caution:Pattern face side: Parts on the pattern face side seen from(Conductor Side) the pattern face are indicated.Parts face side: Parts on the parts face side seen from(Component Side) the parts face are indicated.

Lead layout of conventional IC CSP (chip size package)

Note:The components identi-fied by mark 0 or dottedline with mark 0 are criti-cal for safety.Replace only with partnumber specified.

Note:Les composants identifiés parune marque 0 sont critiquespour la sécurité.Ne les remplacer que par unepièce portant le numérospécifié.
