SERVICING NOTES
NOTES ON HANDLING THE 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 30 cm away from the objecti ve lens.
Before Replacing the Optical Pick-Up Block
Please be sure to check thoroughly the parameters as par the “Optical Pick-Up Block Checking Procedures” (Part No.: 9-960-027-
11) issued separately before replacing the optical pick-up block.
Note and specifications required to check are given below.
• FOK output: IC601 (£ pin (FOK)
When checking FOK, remove the lead wire to disc motor.
• S curve P-to-P value: 0.6-1.8 Vp-p IC501 !§ pin
When checking S curve P-to-P value, remove the lead wire to
disc motor.
• RF signal P-to-P value: 0.8-1.2 Vp-p
• Traverse signal P-to-P value: 1.2 Vp-p
• The repairing grating holder is impossible.
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 than 30 cm apart from
the object lens when you check the emission of laser diode.
• Method-2 (In the service mode or normal operation):
Check the value of current flowing in the laser diode.
1. Remove the upper cabinet.
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 digital voltmeter as shown in Fig. 2.
4. Press the ^ key.
5. Calculate the current value by the r eading of the digital volt-
meter.
Reading of the digital voltmeter (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 +5 mA (25˚C)
–11
Variation by temperature: 0.4 mA/˚C
Current increases with temperature increased.
Current decreases with temperature decreased.
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.

Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper lid is closed while turning ON
the S401 (push switch type).
The following two checking methods for the laser 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 S401 as shown in Fig. 1.
3. Press the ^ key
4. 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.

SERVICE MODE (TEST MODE)
• In this set, there are two test modes; CD-DA Test Mode and
VIDEO CD Test Mode.
How to Enter the Test Mode
1. Disconnect exter nal power (no current is applied to the set).
2. Bridge the SOL701 (TEST) on the MAIN Board with a sol-
der. (IC701 (∞ (TEST) pin is shorted to the ground)
3. Connect the external power.
4. The CD-DA Test Mode is activ ated. (LCD display v aries in 5-
ways, and its 5-way display is repeated)
5. Before connecting exter nal power in step 3, if p (POWER
OFF) key was pressed, the mode is switched to VIDEO CD
Test Mode.
(On the LCD, all segments are displayed, and the TV monitor
becomes 100% white)
How to Release the Test Mode
1. Alw ays disconnect external power , and break the solder bridge
of SOL701 (TEST) on the MAIN Board.
2. Thus, the set become ready for normal operation.
