RCD-W100

Self-diagnosis Function

When the self-diagnosis function is activated to prevent the player from malfunctioning, three character service numbers in a combination with a message appears in the display. In this case, check the following table.

Message

C12/ Cannot Copy

C13/ Rec Error

C14/ TOC Error

C41/ Cannot Copy

C71/ Din Unlock

Explanation

You are trying to record a disc that cannot be played back in DECK-A or with an external device, such as CD-ROM or VIDEO CD.

• Remove the disc, and then insert a music CD for playback.

Recording has not been completed successfully because of vibration.

• Relocate the unit in a place free of vibration and restart the recording again.

The disc you try to record is excessively dirty (such as oilstained or finger marked) or scratched. Or the disc is not normal.

• Replace the disc with another one and restart the recording again.

The unit did not read the TOC information.

• Insert other discs.

The sound source you are trying to record is a copy of a commercial music software. Or you are trying to record on a CD-R/CD-RW digitally.

• Because of the restriction of the Serial Copy Management System, you cannot record copies of commercial music software or MP3 files on DECK A. Neither can you digitally record from a CD-R/CD-RW.

• Use analog recording through the ANALOG IN jack when you record from other units. Or use Synchro-Recording when you record from DECK A. (The recording mode is automatically changed to analog recording.)

If this message is displayed momentarily, this is not an error. It is caused by the digital signal during recording.

During recording of a digital sound source, the connecting cable has been disconnected or the player of the sound source has turned off.

• Connect the cable or turn on the digital player.

This appliance is classified as a CLASS 1 LASER product. This label is located on the rear exterior.

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 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.

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 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.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

SECTION 1

SERVICING NOTE

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 repain parts. The flexible 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 reflective 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. The emission check enables continuous checking of the S curve.

LASER DIODE AND FOCUS SEARCH OPERATION CHECK

Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output three times.

CD SECTION (DECK A)

Note :

1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given.

2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.

3. Use an oscilloscope with more than 10MΩ impedance.

4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks.

S Curve Check

Connection :

oscilloscop

BD board

TP4 (FE)

TP7 (VC)

Procedure :

1. Connect an oscilloscope to test point TP4 (FE) and TP7 (VC) on the BD board.

2. Turn the power on.

3. Load the disc (YEDS-18).

4. Enter the test mode, select the BU Test and press the l AMS L (DECK B) knob to display “bdt S CURVE”.

5. Press the l AMS L (DECK B) knob. “LD AL” is displayed and playback starts automatically.

6. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 3.6 ±

0.5 Vp-p.

7. Press the MENU/NO button to stop playback.

8. Exit from the test mode. (Refer to the TEST MODE Section)
