SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH

MARK 0ON THE SCHEMATIC DIAGRAMS AND INTHE 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.

This appliance is classified as a CLASS 1 LASER product. The

CLASS 1 LASER PRODUCT MARKING is located on the rear

exterior.

Laser component in this product is capable

of emitting radiation exceeding the limit for

Class 1.

CAUTION

Use of controls or adjustments or performance of procedures

otherthan thosespecifiedherein mayresult inhazardous radiation

exposure.

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.

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

repair 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 pick-

up block. Therefore, when checking the laser diode emission,

observe from more than 30 cm away from the objective lens.

HCD-RG11 SECTION 3

TEST MODE

[Cold Reset]

•The cold reset clears all data including preset data stored in the

RAM to initial conditions. Execute this mode when returning

the set to the customer.

Procedure:

1. Press three buttons x, DISPLAY , and ?/1simultaneously.

2. The fluorescent indicator tube displays “COLD RESET” and

the set is reset.

[Aging Mode]

This mode can be used for operation check of CD section and tape

deck section.

•If an error occurred:

The aging operation stops and is displayed status.

•If no error occurs:

The aging operation continues repeatedly.

1. Operating method of Aging Mode

Turn on the main power and select “CD” of the function.

1) Set three discs in tray. SelectALL DISCS, and REPEAT OFF.

2) Load the tapes recording use into both decks.

3) Press three buttons x, DISPLAY , and

DISC SKIP EX-CHANGE simultaneously.

4) Aging operations of CD and tape are started at the same time.

5) To exit the aging mode, perform [Cold Reset].

2. Aging mode in CD section

1) Operation during aging mode

•In the agining mode ,the program is excuted in the following

sequence.

(1) The disc tray opens and closes.

(2) The disc tray turns to select a disc 3.

(3) The pickup accesses to the first track, and plays 3 seconds.

(4) The pickup accesses to the last track, and plays 3 seconds.

(5) The disc tray opens and closes.

(6) The disc tray turns to select a disc 1.

(7) The same operation starts like step (3).

(8) After a disc 1 aging operation, a disc 2 is selected.

(9) When an aging operation of a disc 3 is completed, the display

“AGING ∗∗∗∗” value increases.

(10) If no error occurs, the aging operation continues repeatedly.

ELECTRICAL ADJUSTMENTS

FMTuned Level Adjustment

Procedure:

1. Supplya 98MHz signalat 28 dBfrom theANTENNA terminal.

2. Tune the set to 98 MHz.

3. Adjust RV101 to the point (moment) when the TUNED

indicator will change from going off to going on.

Adjustment Location: MAIN board

Null Adjustment

Procedure:

1. Supplya 98MHz signalat 60 dBfrom theANTENNA terminal.

2. Tune the set to 98 MHz.

3. Measure voltage between pin 21 and pin 23 of IC 101. Adjust

T101 until the voltage becomes 0 V.

Note :

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

Therefore, check each item in order given.

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

3. Use an oscilloscope with more than 10MΩimpedance.

4. Clean the object lens by an applicator with neutral detergent

when the signal level is low than specified value with the

following checks.
