CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous 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.
Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.
This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior.
This caution label is located inside the unit.
SAFETY-RELATED COMPONENT WARNING !!
COMPONENTS IDENTIFIED BY MARK !OR DOTTED LINE WITH MARK !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.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
LEAKAGE
The AC leakage from any exposed metal part to earth Ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microampers). Leakage current can be measured by any one of three methods.
1.A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers’ instructions to use these instruments.
2.A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.
3.Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)

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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
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 four times.

About CD-TEXT display
This unit is provided with a simple CD-TEXT display function. The CD-TEXT contents of 20 tracks are displayed on the fluorescent display tube.
Since the function is simple, some special characters may not be displayed, or may be displayed as other characters.

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. Press three buttons t/CLOCK SET , ENTER , and 1/u simultaneously.
2. “COLD RESET” is displayed on the fluorescent display tube and reset is executed.
CD Delivery Mode
• This mode moves the pick-up to the position durable to vibration. Use this mode when returning the set to the customer after repair.
Procedure:
1. |
Press |
1/u |
button to turn the set ON. |
||||
2. |
Press |
|
|
|
button and |
1/u |
button simultaneously. |
|
LOOP |
||||||
3. |
A message “LOCK” is displayed on the fluorescent indicator tube, and the CD delivery mode is set. |
MC Hot Reset
• This mode resets the set with the preset data kept stored in the memory. The hot reset mode functions same as if the power cord is plugged in and out.
Procedure:
1. |
Press three buttons |
t/CLOCK SET |
, |
ENTER |
, and |
DISC 1 |
simultaneously. |
2. |
The fluorescent indicator tube becomes blank instantaneously, and the set is reset. |
Sled Servo Mode
• This mode can run the CD sled motor freely. Use this mode, for instance, when cleaning the pick-up.
Procedure:
1.Press 1/u button to turn the set ON.
2.Press three buttons t/CLOCK SET , 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, When the =AMS + knob is rotated in the clockwise direction, the pick-up moves outside. When rotated counterclockwise, it moves inside.
5.To exit from this mode, perform as follows:
1)Move the pick-up to the most inside track.
2)Execute MC cold reset. (Press the three buttons t/CLOCK SET , ENTER , and 1/u button simultaneously.)
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 AM Tuner Step between 9kHz and 10kHz
• A step of AM channels can be changed over between 9kHz and 10kHz.
Procedure:
1.Press 1/u button to turn the set ON.
2.Select the function “TUNER”, and press TUNER/BAND button to select the BAND “AM”.
3.Press 1/u button to turn the set OFF.
4.Press ENTER and 1/u buttons simultaneously, and the display of fluorescent indicator tube changes to “AM 9k STEP” or “AM 10k STEP”, and thus the channel step is changed over.
LED and Fluorescent Indicator Tube All Lit, Key Check Mode
Procedure:
1. Press three buttons t/CLOCK SET , ENTER , and DISC 2 simultaneously.
2.LEDs and fluorescent indicator tube are all turned on. Press DISC 2 button, and the key check mode is activated.
3. |
In the key check mode, the fluorescent indicator tube displays “K @ V0 J0”. Each time a button is pressed, “K”value increases . However, |
||||
|
once a button is pressed, it is no longer taken into account. |
||||
|
“J” Value increases like 1, 2, 3 ... if rotating |
=AMS + |
knob in “+” direction, or it decreases like 0, 9, 8 ... if rotating in “-” |
||
|
direction. |

4.“TEST MODE” is displayed on the fluorescent display tube.
5.Press the FUNCTION button and switch the function to the deck with the tape (AMS-110A).
6.Press the CD SYNCHRO button. “AMS CHECK” is displayed on the fluorescent display tube and the tape is rewound.
7.AMS starts in the normal direction. If the AMS count is 2 at shut down, proceed to step 8. “NG” is displayed at other times, and the deck stops.
8.AMS starts in the opposite direction. If the AMS count is 2 at shut down again, “OK” is displayed. “NG” is displayed at other times.

Procedure:
INTRODUCTION
When set to the test mode performed in Tape Speed Adjustment, when the tape is rewound after recording, the “REC memory mode” which rewinds only the recorded portion and playback is set.
This “REC memory mode” is convenient for performing this adjustment. During recording, the input signal FUNCTION will automatically switch to VIDEO 1.
(After recording, press the 0 button without stopping will return to the position where recording was started.)
1.Press FUNCTION button to select VIDEO 1. (This step is not necessary if the above test mode has already been set.)
2.Insert a tape into deck B, press the r REC button, and then press the · button to start recording.

•U : B+ Line.
•V : B– Line.
•H : adjustment for repair.
•Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions.
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
•Circled numbers refer to waveforms.
•Signal path. F : FM
g : VIDEO/MD
E : PB (DECK A) d : PB (DECK B)
G : REC (DECK B)
J : CD
c : digital out
I : PHONO
•Abbreviation
CND : Canadian model.
AUS : Australian model.
For printed wiring boards.
Note:
•X : parts extracted from the component side.
•® : Through hole.
•¢ : internal component.
