SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTEDLINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMSAND IN THE PARTS LIST ARE CRITICAL TO SAFEOPERATION. REPLACE THESE COMPONENTS WITHSONY PARTS WHOSE PART NUMBERS APPEAR ASSHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-LISHED BY SONY.

CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous ra-diation exposure.

Notes 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 the soldering iron around 270 ˚C dur-

ing 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.

SERVICING NOTES

DISC MAGAZINE GETTING OUT PROCEDUREON THE POWER SUPPLY IS OFF

Remove the COVER (LOWER.T) assy beforehand

1) Press the lever (ML.S) to arrow direction.2) Removal the magazine assy.Note: Take out the magazine only when the tray is completely within the

magazine. If the disk or tray is sticking out, turn on the power andeject the magazine.

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

Lever (ML.S)

Magazine assy

The laser diode in the optical pick-up block may suffer electro-static breakdown because of the potential difference generated bythe charged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic breakdown and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.

NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focusedon the disc reflective surface by the objective lens in the opticalpick-up block. Therefore, when checking the laser diode emis-sion, observe from more than 30 cm away from the objective lens.

TEST DISCThis set can playback a CD-R, CD-RW for audio use. When testthis set, use the following test disc.Test disc for CD-R: TCD-R082LMT (Part No.: J-2502-063-1)

Notes on CD-R/CD-RW discs

You can play CD-Rs (recordable CDs)designed for audio use on this unit.

Look for this mark todistinguish CD-Rs for audiouse.

This mark denotes that adisc is not for audio use.

Some CD-Rs (depending on the equipmentused for its recording or the condition ofthe disc) may not play on this unit.

You cannot play a CD-R that is notfinalized*.You cannot play CD-RWs (rewritable CDs).

MECHANICAL ADJUSTMENTS

• Elevator Height (Address) Adjustment

Note: This adjustments is necessary when the system controller (IC201),variable resistor (RV201), slider (R), slider (L), or chassis (ELV)was replaced for any repair.

Connection:

Adjustment Method:1. Load a disc magazine, and place the set vertically as shown

below.2. Connect the regulated power supply, and turn the power on.3. Press the DISC button on the wired remote commander (RM-

X82RF) and select DISC 5.4. At this time, if the elevator shaft does not position between

comb teeth A and B at addresses 5 and 6 as shown below,adjust the following.

5. Press repeatedly the DISC + and – buttons on the wired re-mote commander (RM-X82RF) so that the elevator shaftsmoves from address 6 to address 5, or from 5 to 6. At thistime, adjust RV201 on the main board so that the elevator shaftpositions smoothly between comb teeth A and B.

6. Further, place the set horizontally and make same adjustmentas mentioned above.

7. After adjustment at addresses 5 to 6 is finished, check all op-erations from addresses 1 to 10 with the set placed verticallyand horizontally respectively to confirm that the elevator shaftpositions in a range between comb teeth A to B.

Note:1. This adjustment is performed with the set placed horizontally.2. Power supply voltage: DC14.4 V (more than 3 A).3. Be sure to use the disc “YEDS-18” parts code: 3-702-101-01, but only

when indicated.

Connection:

Focus Bias Check

Connection:– RF Board (Component Side) –

Procedure:1. Connect the oscilloscope to TP (RFO) and TP (VC) on the RF

board.2. Put the set into play mode by loading the disc (YEDS-18).3. Confirm that oscilloscope waveform is clear and check RF sig-

nal level is correct or not.Note:Clear RF signal waveform means that the shape “◊” can be clearly distin-guished at the center of the waveform.

When observing the eye pattern, set the oscilloscope to AC rangeand raise the vertical sensitivity so that it may be easily seen.
