SERVICING NOTES
NOTES ON HANDLINGTHE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown 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 30cm away from the objective lens.
Before Replacing the Optical pick-up Block
Pleasebe sure to check thoroughly the parameters asper the “Optical
pick-upBlock CheckingProcedure” (PartNo. :9-960-027-11)issued
separately before replacing the optical Pick-up block.
Note and specifications required to check are given below.
• FOK output : IC501 !™ pin
When checking FOK, remove the lead wire to disc motor.
• S curve P-to-P value : 0.9 – 1.5Vp-p IC501#¡ pin. (Connect pin
!™ of IC501 (TP880) and 3of IC501 (GND) with a jumper
wire).
When checking S curve P-to-P value, remove the lead wire to
disc motor.
• Adjusted part for focus gain adjustment : RV503
• RF signal P-to-P value : 0.85 – 1.15Vp-p
• Traverse signal P-to-P value : 1.0 – 2.6Vp-p
• The repairing grating holder is impossible.
• Adjusted part for tracking gain adjustment : RV502

Precautions for Checking Emission of Laser Diode
Laser light of the equipment is focused by the object lens in the
optical pick-up so that the light focuses on the reflection surface of
the disc.
Therefore, be sure to keep your eyes more then 30cm apart from
the object lens when you check the emission of laser diode.
Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper panel is closed while turning
ON the S801 (push switch type).
Thefollowing twochecking methodsfor thelaser diode are operable.
Method-1 (In the service mode or normal operation) :
Emission of the laser diode is visually checked.
1. Open the upper lid.
2. Push the S801 as shown in Fig. 1 .
3. Check the object lens for confirming normal emission of the
laser diode. If not emitting, there is a trouble in the automatic
power control circuit or the optical pick-up. During normal
operation, the laser diode is turned ON about 2.5 seconds for
focus searching.
Fig.1 Method to push S801
Method-2 (In the service mode or normal operation) :
Check the value of current flowing in the laser diode.
1. Remove the upper panel.
2. Read the current printed on the rear side of the optical pick-up.
(Print on the rear side of the optical pick-up)
3. Connect a level meter as shown in Fig. 2
4. Press the ^key.
5. Calculate thecurrent value by the readingof the digital voltmeter
Reading of the tester (V) ÷4.7 ( Ω) = current value (A)
(Example) Reading of the digital voltmeter of 0.2256 V :
0.2256 V ÷4.7 Ω= 0.048 (A) = 48 mA
6. Check that the current value is within the following range.
• Current value of the label mA(25°C)
Variation by temperature : 0.4mA/ °C
Current increases with as temperature increases.
Current decreases with as temperature decreases.
If the current is more than the range above, there is a trouble in the
automatic power control circuit or the laser diode is in deterioration.
If less than the range, a trouble exists in the automatic power control
circuit or the optical pick-up.

SERVICE MODE
Service Mode (service program)
The equipment is provided with a service program built in the
microcomputer, like conventional models.
Service program operation methods are described in the following.
• Step 1 (Service mode setting method)
1. Turn OFF the HOLD switch the external power supply discon-
nected (power is not applied to the set).
2. Solder across the T802(TEST) terminals (pin%¢, IC801 (TEST)
is grounded).
3. Connect an external power supply.
Thus, the set is switched to the service mode.
• Step 2 (Operation in the service mode )
1. Once the service mode is effected, the LCD displays 5 indica-
tions each of which is repeatedly displayed.
However,the following operations can be activated even if LCD
indication is effected.
2. By pressing the +or =key, the optical pick-up movable
inwardly or outwardly. However, if this is activated, tracking
servo and sled servo are turned OFF, so it can be turned ON by
pressing the PLAY MODE key, if required.
3. By pressing the REPEAT/ENTER key, the tracking gain-up
mode becomes active.
4. By pressing the ^key, focus is turned ON from focus search-
ing while entering CLV-S (pull-in mode).
Without disc, focus searching is repeated continuously.
5. By pressing the PLAY MODE key, tracking servo, sled servo
and CLV-A (servo in PLAY) are turned ON.
6. When 4. and 5. are performed, playing begins. No muting is
ON in the service mode.
7. By pressing the pkey, all servos (focus tracking and sled) are
turned OFF. However, the disc motor revolves for a while by
inertia.
• Step 3 (Resetting service mode )
1. Be sure to disconnect the external power supply and remove
the solder bridge at the TEST terminals connected in setting.
2. The set thus becomes available for normal operation.

Focus/Tracking Gain Adjustment
A servo analyzer is necessary in order to perform this adjustment
exactly.
However, this gain has a margin, so even if it is slightly off,
there is no problem. Therefore, do not perform this adjustment.
Focus/tracking gain determines the pick-up follow-up relative to
mechanical noise and mechanical shock when the 2-axis device
operate. However, as these reciprocate, the adjustment is at the point
where both are satisfied.
• When gain is raised, the noise when 2-axis device operates in-
creases.
• When gain is lowered, it is more susceptible to mechanical shock
and skipping occurs more easily.
This adjustment has to be performed upon replacing any of the fol-
lowing parts :
• Optical pick-up
• RV503 (Focus gain)
• RV502 (Tracking gain)
Normally, be sure not to move RV503 (focus gain) and RV502
(tracking gain).
– Focus GainAdjustment –
Procedure :
This adjustment is not performed. If focus gain RV503 is turned,
set to mechanical center.
– Tracking Gain Adjustment –
(perform at normal operation)
[MAIN BOARD] (Side B)
1. Place the optical pick-up level, horizontally. (If the optical pick-
up is not level, the2-axis device will beweighted and adjustment
cannot be done.)
2. Connect the oscilloscope between IC501 0pin (TEO) and #º
pin (VC) on the MAIN board.
3. Set the disc (YEDS-18) and Press the ^(+) key.
4. Turn RV502 slightly clockwise (tracking gain drops) and obtain
a waveform with a fundamental wave (waveform has large
waves) as in Fig. 1 .
5. Turn RV502 slowly counterclockwise (tracking gain rises) until
the fundamental wave disappears (no large waves) as in Fig. 2.
6. Set RV502 to the position about 30°counterclockwise from the
position obtained in step 5. If RV502 contact point is more than
90°counterclockwise from mechanical center, tracking gain is
too high. In this case, readjust from step 4.
7. Press ^(+) or =keys and observe the 100 track jump
waveform. Check that no traverse waveform appears for both
^(+)or =directions. (See Fig. 3and 4.) It is acceptable
if the traverse waveform appears only now and then, but if it
appears constantly raise tracking gain slightly and check step 7
again.
8. Check that there is no abnormal amount of operation noise (white
noise) from the 2-axis device. If there is, tracking gain is too
high, readjust starting with step 4.
The waveforms are those measured with the oscilloscope set as
shown below.
• VOLT/DIV : 50mV
• TIME/DIV : 5mS
• Waveform when tracking gain lowered.
Fundamental wave appears (Large amplitude appears.)
• Waveform when fundamental wave disappears (Large
amplitude does not appear.)
• Waveform when no traverse waveform during 100 track jump.
(Brake application is smooth because of adjustment.)
• Waveform when no traverse waveform during 100 track jump.
(Brake application is poor because of adjustment.)
