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.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
CAUTION
The use of optical instruments with this product will increase eye hazard.
DANGER INVISIBLE LASERRADIATIONWHEN OPEN.
AVOID DIRECT EXPOSURE TO BEAM.
This is located on the drive unit's internal chassis.

SECTION 1
SERVICING NOTES
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. During 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
Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight.
NOTE WHEN REPAIRING OR REPLACING THE CORDLESS STEREO HEADPHONES
The Cordless Stereo Headphones attached to this set have been changed in the midway of production. Repair or replace the Cordless Stereo Headphones after making sure which type they are by referring to the following figure.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead­free 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 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 regulator 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 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.

• Note for Printed Wiring Boards and Schematic Diagrams • Circuit Boards Location
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• x : parts mounted on 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 (Side B) the pattern face are indicated. Parts face side: Parts on the parts face side seen from (Side A) the parts face are 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.
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums.
• All resistors are in Ω and 1/
4
W or less unless otherwise
specified.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
• Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark : DVD PLAY (): STANDBY
∗ : Impossible to measure
• Voltages are taken with a V OM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc­tion tolerances.
• Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal produc­tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
