TABLE OF CONTENTSNotes on chip component replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be dam-

aged 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.

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

CAUTIONUse of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radiation exposure.

SAFETY-RELATED COMPONET WARNING!

SECTION 1SERVICING NOTES

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

The laser diode in the optical pick-up block may suffer electrostat-ic 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 CHECKThe 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 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 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 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.

RELEASING THE DISC TRAY LOCKThe disc tray lock function for the antitheft of an demonstration disc in the store is equipped.

Releasing Procedure:1. Press [?/1] button to turn the power on.2. Press the [FUNCTION] button to select CD function.3. While pressing the [x] button, press the [Z] button for more 5

seconds).4. The message “UNLOCKED” is displayed and the disc tray is

unlocked.

Note: When “LOCKED” is displayed, the slot lock is not released by turning power on/off with the [?/1] button.

CD SERVICE MODEThis mode can move the SLED of the optical pick-up, and also can turn the optical pick-up laser power on and off.Procedure:1. Press the [I/1] button to turn the power on.2. Press three buttons of [u], [TUNING + M L], and

DISPLAY simultaneously.3. Press the [FUNCTION] button to select CD function.4. It enters the CD service mode and displays “SERVICE”.5. To exit from this mode, press three buttons of [u], [TUN-

ING + M L] and DISPLAY simultaneously.

Key Operation:[TUNING + M L], [l m – TUNING]: Use these keys to move the SLED. When [TUN-

ING + M L] is pressed in this mode, the SLED moves to outer circumference and the message “SLED OUT” is displayed.

When [l m – TUNING] is pressed in this mode, the SLED moves to inner circumference and the message “SLED IN” is displayed.

[DISPLAY]: Use this key to turn the optical pick-up laser power

on and off. When the laser power is turned on, the message “LD ON” is displayed. When the laser power is turned off, the message “LD OFF” is dis-played.

CD ERROR CODEThe past errors of the CD mechanism (CDM) are displayed as the CDM Errors, and those of the optical pick-up system (= optical unit + CD board) are displayed as the BD Errors as shown below. Procedure:1. Press the [I/1] button to turn the power on.2. Press the [FUNCTION] button to select CD function.3. Press three buttons of [TUNING + M L], [x] and [DIS-

PLAY] simultaneously.4. Then, the CDM error code is displayed as “M0xxxxxx” (x

means hexadecimal number) on the liquid crystal display as shown below.

5. Every pressing of the [TUNING + M L] button in this mode increments the number after “M” starting from “M0” up to “M9”, and then returns to “M0”. Every pressing of the [l m – TUNING] button in this mode decrements the number after “M”. The smaller the error code number is, the newer the error content is.

6. When the [USB SYNC REC/REC 1] button is pressed then, the BD error code is displayed as “D0xxxxxx” (x means hexa-decimal number) on the liquid crystal display as shown below. In the same way as the CDM error code, use of the [TUNING + M L] and the [l m – TUNING] buttons in this mode enables tracing of the error history.

7. To release from this mode, press the [I/1] button to turn the power off.

CD FACTORY MODE

Note1: Do not enter the [CD FACTORY MODE] while any other test-mode is in progress.

Note2: Do not enter any other test mode while the [CD FACTORY MODE] is in progress.

Procedure:1. Press the [?/1] button to turn the power on.2. Press the [FUNCTION] button to select CD function3. Press three buttons of [u], [USB], and [DISPLAY] simulta-

neously.4. It enters the CD factory mode and displays the following mes-

sage.

Key Operation:[DISPLAY]: The display changes in the following order when-

ever the button is pressed.

(Initial display)

fcsAG ** (**: Focus AGC value)

trkAG ** (**: Track AGC value)

RF-AG ** (**: RF AGC value)

[DSGX]: RF gain setting changes whenever the button is

pressed. “–”: No gain fi xation. “AL”: Fix to the gain for AL disc. “RW”: Fix to the gain for RW disc.

[EQ]: Tracking servo setting changes whenever the but-

ton is pressed. “ON”: Tracking servo ON. “OFF”: Tracking servo OFF.

[FUNCTION]: S character mode setting changes whenever the but-

ton is pressed. “ ”: S character mode OFF. “S”: S character mode ON.

5. To release from this mode, press the [?/1] button to turn the power off.

Note:1. CD Block is basically constructed to operate without adjustment.2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.3. Use an oscilloscope with more than 10 MΩ impedance.4. Clean the object lens by an applicator with neutral detergent when the

signal level is low than specifi ed value with the following checks.5. Check the focus bias check when optical pick-up block is replaced.

Procedure :1. Turn the power on.2. Input the following signal from Signal Generator to FM an-

tenna input directly.

* Carrier Freq : A = 87.5 MHz, B = 98 MHz, C = 108 MHz Deviation : 75 kHz Modulation : 1 kHz ANT input : 35 dBu (EMF)

Note: Please use 75 ohm “coaxial cable” to connect SG and the set. You cannot use video cable for checking.

Please use SG whose output impedance is 75 ohm. 3. Set to FM tuner function and scan the input FM signal with

automatic scanning.4. Confi rm that input Frequency of A, B and C detected and auto-

matic scanning stops. The stop of automatic scanning means “The station signal is re-ceived in good condition”.
