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.

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.

Notes on the power source

Disconnect all power sources when the CD player is not used for a long time.

On AC power adaptor

• Use only the AC power adaptor supplied. If your CD player is not supplied with the one, use the A C-E30HG AC power adaptor. Do not use any other AC power adaptor. It may cause a malfunction.

Polarity of the plug

• Do not touch the AC power adaptor with wet hands.

• Connect the A C po wer adaptor to an easily accessible A C outlet. Should you notice an abnormality in the AC power adaptor, disconnect it from the AC outlet immediately.

UNLEADED SOLDER

Boards 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 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 f low) 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.

SECTION 1

SERVICE NOTE

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

The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body . During repair, pay attention to electrostatic breakdown 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.

Precautions for Checking Emission of Laser Diode

Laser light of the equipment is focused by the object lens in the optical pick-up so that the light focuses on the reflection surface of the disc. Therefore, be sure to keep your eyes more then 30 cm apart from the object lens when you check the emission of laser diode.

Before Replacing the Optical Pick-Up Block

Please be sure to check throughly the parameters as par the “Optical Pick-Up Block Checking Procedures” (Part No.: 9-960-027-

11) issued separately before replacing the optical pick-up block. Note and specifications required to check are given below.

• FOK output : IC601 yg pin (or TP624 (FOK)) When checking FOK, remove the lead wire to disc motor.

• RF signal P-to-P value : 0.45 ± 0.1 Vp-p

• The repairing grating holder is impossible.

Laser Diode Checking Methods

During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S803. (push switch type) The following two checking methods for the laser diode are operable.

• Method: Emission of the laser diode is visually checked.

1. Open the upper lid.

2. With a disc not set, turn on the S803 with a scre wdri v er having a

thin tip. Note: Do not push the detection lever strongly , or it may be bent

or damaged.

3. Press the N X button.

4. Obser ving the objective lens, check that the laser diode emits

light. When the laser diode does not emit light, automatic power control circuit or optical pick-up is faulty. In this operation, the objective lens will move up and down 5 times along with inward motion for the focus search.
