SERVICING NOTE
SELF-DIAGNOSIS
This model has the self-diagnosis function for the VIDEO and
AUDIO decoder sections.
Immediately after the power on, the self-diagnosis function searches
each operation of IC’s around the mechanism control microcomputer
(IC701).
The results can be checked by connecting an oscilloscope to TP709
(LED) of the VIDEO board.

TEST MODE
VIDEO CD COLOR-BARS MODE
On this mode, the data of the color-bars signal as a picture signal
and the 1kHz sine wave signal as a sound signal are output by the
mechanism control microcomputer (IC701) for 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 J9001
(VIDEO OUT) and the sound signal can be observed at J101
(VIDEO (AUDIO) OUT) using an oscilloscope.
1. Connect the lead wire to both ends of the land of SL701 (CAL
BAR) of the VIDEO board.
2. Turn the power on. Press FUNCTION button to select CD.
3. After 2 or 3 seconds later, connect the lead wire.
4. After measuring, remove the lead wire connected.
Note : The 1kHz sine wave is not outputted when the CD is played
once, but it is not error.

Note :
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MΩ impedance.

Procedure :
1. Connect oscilloscope to test point TP (RF) on BD board.
2. Turned Power switch on.
3. Put disc (YEDS-18) in to play the number five track.
4. Confirm that oscilloscope waveform is clear and check RF
signal level is correct or not.
Note : A clear RF signal waveform means that the shape “◊” can
be clearly distinguished at the center of the waveform.
RF signal waveform
Procedure :
1. Connect oscilloscope to test point TP (FE) on BD board.
2. Connect between test point TP (FEI) and TP (VC) by lead wire.
3. Turned Power switch on.
4. Put disc (YEDS-18) in and turned Power switch on again and
actuate the focus search. (actuate the focus search when disc
table is moving in and out.)
5. Check the oscilloscope waveform (S-curve) is symmetrical
between A and B. And confirm peak to peak level within 3 ± 1
Vp-p.
