CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.

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 270C

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.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITHMARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTSLIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESECOMPONENTS WITH SONY PARTS WHOSE PART NUMBERSAPPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTSPUBLISHED BY SONY.

NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

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

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

LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the S curve check in CD section adjustment andcheck that the S curve waveforms is output three times.

HCD-XGR80SECTION 3TEST MODE

[MC Cold Reset] The cold reset clears all data including preset data stored in the

RAM to initial conditions. Execute this mode when returningthe set to the customer.

Procedure:1. Turn the power ON or set to the DEMO mode.2. Press three buttons of c/CLOCK SET , TUNER ENTER ,

and \/1 simultaneously.3. The set is reset, and displays COLD RESET, then becomes

DEMO mode.

[Change-over the AM Tuning Interval] The AM tuning interval can be changed over 9 kHz or 10 kHz.Procedure:1. Press the \/1 button to turn the power ON.2. Select the function TUNER, and press the TUNER/BAND

button to select the BAND AM.3. Press the \/1 button to turn the power OFF.4. Press the ENTER/NEXT and \/1 buttons simultaneously,

and the display on the fluorescent indicator tube changes toAM 9 K STEP or AM 10 K STEP, and thus the tuninginterval is changed over.

[CD Ship Mode] (No memory clear) This mode moves the optical pick-up to the position durable to

vibration. Use this mode when returning the set to the customerafter repair.

Procedure:1. Press the \/1 button to turn the power ON.2. Press the EDIT and \/1 buttons simultaneously.3. A message LOCK is displayed on the fluorescent indicator

tube, and the CD delivery mode is set.

[LED and Fluorescent Indicator Tube All Lit, Key CheckMode]Procedure:1. Press three buttons of c/CLOCK SET , ENTER/NEXT ,

and DISC 2 simultaneously.2. LEDs and fluorescent indicator tube are all turned on.3. Press the DISC 1 button, the MODE and DESTINATION are

displayed fluorescent indicator tube.4. Each time the DISC 1 button is pressed, the MC/GC category

version is displayed in the following order.5. Press the DISC 2 button, and the key check mode is acti-vated.

6. In the key check mode, the fluorescent indicator tube displaysK 0 J0 V0. Each time a button is pressed, K value in-creasesto K69call the button is pressed.However, once a button ispressed, it is no longer taken into account.J value increases like 1, 2, 3 ... if turn the . AMS >JOG dial clock-wise,or it decreases like 0, 9, 8 ... if turn the . AMS > JOG dial counter-clockwise.V value increases like 1, 2, 3 ... if turn the VOLUME dialclockwise (+ direction), or it decreases like 0, 9, 8 ... if turnthe VOLUME dial counterclockwise ( direction).

7. To release from this mode, press three buttons in the samemanner as step 1, or disconnect the power cord.

[Sled Servo Mode] (CD service mode) This mode can run the CD sled motor freely. Use this mode, for

instance, when cleaning the pick-up.Procedure:1. Select the function CD.2. Press three buttons c/CLOCK SET , TUNER ENTER , and

DISC 5 simultaneously.3. The Sled Servo mode is selected, if CD is blanking on the

fluorescent indicator tube.4. With the CD in stop status, press M button in CD section to

move the pick-up to outside track, or m button to inside track.5. To exit from this mode, press \/1 button turn to the power

OFF.Note: Always move the pick-up to most inside track when exiting from

this mode. Otherwise, a disc will not be unloaded. Do not run the sled motor excessively, otherwise the gear can

be chipped.

[Change-over of FUNCTION Name] The FUNCTION name of external input terminal can be changed

over to VIDEO or MD. With the FUNCTION selected to MD,about 5dB mute is applied to the input gain.

Procedure:1. Press \/1 button to turn the power OFF.2. Press \/1 button together with FUNCTION button for

several seconds, and the power is turned on, the display offluorescent indicator tube changes to MD or VIDEOinstantaneously, and thus the FUNCTION is changed over.

[Aging Mode]This mode can be used for operation check of tape deck section.Tape deck section work in parallel. If an error occurred:

The aging operation stops and display then status. If no error occurs:

The aging operation continues repeatedly.

Procedure:1. Load the tapes into the decks A and B respectively.2. Press the FUNCTION button to select the function CD.3. Press the PLAY MODE button to set the ALL DISCS mode,

and press the REPEAT button to REPEAT off.4. Press three buttons of c/CLOCK SET , TUNER ENTER ,

and DISC 4 simultaneously.5. The aging mode is activated, if the indicator of disc tray num-

ber on the fluorescent indicator tube is blinking.6. To release from the aging mode, press the \/1 button to turn

the power OFF and operate the cold reset. (Refer to the MCCold Reset)

1. Display at the Aging Mode Display operating state of tape deck section alternately. If an error occurred, stop display.

CD SECTION

Note :1. CD Block is basically designed to operate without adjustment.

Therefore, check each item in order given.2. Use LUV-P01 (4-999-032-01) unless otherwise indicated.3. Use an oscilloscope with more than 10M impedance.4. Clean the object lens by an applicator with neutral detergent

when the signal level is low than specified value with thefollowing checks.

S-Curve Check

BD boardOscilloscope

TP(FE)TP(DVC)

Procedure :1. Connect oscilloscope to TP (FE).2. Connect between TP (FE) and TP (DVC ( 1.65 V) by lead

wire.3. Press the \/1 button to turn the power ON.4. Load a disc (LUV-P01) and actuate the focus search. (In conse-

quence of open and close the disc tray, actuate the focus search)5. Confirm that the oscilloscope waveform (S-curve) is symmetri-

cal between A and B. And confirm peak to peak level within 20.5 Vp-p.

6. After check, remove the lead wire connected in step 2.Note : Try to measure several times to make sure than the ratio

of A : B or B : A is more than 10 : 7. Take sweep time as long as possible and light up the brightness to obtain best waveform.

RF Level Check

TP(RFDC)TP(RFAC)

BD boardoscilloscope

Procedure :1. Connect oscilloscope to TP2 (RFDC) and TP1 (RFAC).2. Press the \/1 button to turn the power ON.3. Load a disc (LUV-P01) and playback.4. Confirm that oscilloscope waveform is clear and check RF

signal level is correct or not.

Note: Clear RF signal waveform means that the shape can be clearly distinguished at the center of the waveform.
