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.

CAUTION

Use of controls or adjustments or performance of procedures other than those speciﬁ ed herein may result in hazardous radia- tion exposure.

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

SERVICING NOTES

HCD-EH25/EH26

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

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 ﬂ exible board is easily damaged and should be handled with care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on the disc reﬂ ective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

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 viscous (sticky, less prone to ﬂ ow)

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.

LASER DIODE AND FOCUS SEARCH OPERATION CHECK

During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning on the SW750. (push switch type) The following checking method for the laser diode is operable.

• Method Emission of the laser diode is visually checked.

1. Open the upper lid.

2. Push the SW750 as shown in Fig.1.

Note: Do not push the detection lever strongly , or it may be bent or dam-

aged.

3. Check the object lens for conﬁ rming normal emission of the laser diode. If not enitting, there is a trouble in the automatic power control cirsuit or the optical pick-up.

In this operation, the object lens will move up and down 2

times along with inward motion for the focus search.

Note:

• 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 speciﬁ ed.

• f : internal component.

• C : panel designation.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

• A : B+ Line.

• H : adjustment for repair.

• Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions.

• Voltages are taken with VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal production

tolerances.

• Waveforms are taken with a oscilloscope.

Note:

• X : Parts extracted from the component side.

• Y : parts extracted from the conductor side.

• W : indicates side identiﬁ ed with part number.

• f : internal component.

• : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

• Indication of transistor.

Note: The components identiﬁ ed by mark 0 or dotted

line with mark 0 are critical for safety.

Replace only with part number speciﬁ ed.
