SERVICING NOTES
SELF-DIAGNOSIS
This unit is equipped with a self-diagnosis function.
The function is used for diagnosing the conditions of the circuits
of the VIDEO board.
The circuits can be determined if normal or abnormal by the lighting of D502 of the VIDEO board.
Lighting of D502
When lit: Operates normally
Blinks repeatedly : The circuit may be faulty.
– VIDEO Board (Side A) –
IC505
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.
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 the 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 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. Turn the power ON or set to the DEMO mode.
2. Press three buttons of p , [ENTER/NEXT], and [DISC1] si-
multaneously.
3. The set is reset, and becomes standby state.

(EXCEPT Saudi Arabia model)
• The AM tuning interval can be changed over 9 kHz or 10 kHz.
Procedure:
1. Press the 1/u button to turn the power ON.
2. Select the function “TUNER”, and press the [TUNER/BAND]
button to select the BAND “AM (MW)”.
3. Press the 1/u button to turn the power OFF.
4. Press the [ENTER/NEXT] and 1/u buttons simultaneously,
and the display on the fluorescent indicator tube changes to
“AM 9 k STEP” or “AM 10 k STEP”, and thus the tuning
interval is changed over.
[CD Delivery Mode]
• This mode moves the optical pick-up to the position durable to
vibration. Use this mode when returning the set to the customer
after repair.
Procedure:
1. Press the 1/u button to turn the power ON.
2. Press the [CDLOOP] and 1/u buttons simultaneously.
3. A message “LOCK” is displayed on the fluorescent indicator
tube, and the CD delivery mode is set.

multaneously.
2. LEDs and fluorescent indicator tube are all turned on.
Press the [DISC2] button, and the key check mode is activated.
3. In the key check mode, the fluorescent indicator tube displays
“K 0 J0 V0”. 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 turn the JOG dial clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial counterclockwise.
“V” value increases like 1, 2, 3 ... if turn the [VOLUME] dial
clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial
counterclockwise.
4. To exit from this mode, press three buttons in the same man-
ner as step 1, or disconnect the power cord.

3. Press the [PLAYMODE] button to set the “ ALL DISCS” mode,
and press the [REPEAT] button to “REPEAT” off.
4. Press three buttons of p , [ENTER/NEXT], and [DISCSKIP/
EX-CHANGE] simultaneously.
5. The aging mode is activated, if the indicator of disc tray num-
ber on the fluorescent indicator tube is blinking.
6. To exit from the aging mode, press the 1/u button to turn the
power OFF and operate the cold reset. (Refer to the “MC Cold
Reset”)
1. Display at the Aging Mode
• Display operating state of tape deck section alternately.
• If an error occurred, stop display.
2. Tape Deck Section
• The sequence during the aging mode is following as below.
• If an error occurred, stop display that step.

[VIDEO CD Color-bars Mode]
On this mode, the data of the color-bars signal as a picture signal
and the 1 kHz sine wave signal as a sound signal are output by the
mechanism controller (IC502) for the video CD signal check.
When measurement of the voltage and waveform on the VIDEO
board, perform it in this mode.
For reference, the color-bars signal can be observed at J302
(VIDEO OUT) and the sound signal can be observed at J101
(VIDEO/MD (AUDIO) OUT) using an oscilloscope.
Procedure:
1. Short the both ends of the land of SL503 of the VIDEO board.
2. Turn the power on. Press the [FUNCTION] button to select
CD.
3. The color-bars appears when the CD is in stop status, and it
disappears when the CD goes in play status.
4. After measuring, remove the lead wire connected.

Procedure:
1. Connect oscilloscope to TP (RF).
2. Connect between TP (AGCCON) and TP (GND) by lead wire.
3. Turn the power ON.
4. Load a disc (YEDS-18) and press the ^ button to play.
5. Confirm that the oscilloscope waveform is clear and check RF
signal level is correct or not.
6. After check, remove the lead wire connected in step 2.
Note: Clear RF signal waveform means that the shape “≈” can be clearly
