PROTECTION
OF
EYES
FROM
LASER
BEAM
DURING
SERVICING
This set employs a laser. Therefore, be sure to follow carefully the
instructions below when servicing.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
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 sureface 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.
SAFETY-RELATED COMPONENT WARNING!!

1. Laser Diode Properties
* Material: GaAlAs
* Wavelength: 780nm
¢ Emission Duration: continuous
¢ Laser Output: max.44.6.W*
* This output is the value measured at a distance of about
200mm from the objective lens surface on the Optical Pick-up
Block.
2. During service, donot take the Optical Pick-up Block apart, and
do not adjust the APC circuit. If there is a breakdown in the APC
circuit (including laser diode), replace the entire Optical Pick-
up Block (including APC board).
LASER DIODE AND FOCUS SERCH OPERATION
CHECK
1. Make POWER switch on with no disc inserted and disc table
closed.
2. Confirm that the following operation is performed while observ-
ing the objective lens.
@ Confirm that laser beam is spread.
e Up and down motion of the objective lens. (3 times)

ELECTRICAL BLOCK CHECKING
Note :
1. CDBlock basically constructed 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 the oscilloscope with more than 10OMQ impedance.
4. Clean an object lens by an applicator with neutral detergent
when the signal level is low than specified value with the
following checks.
S Curve Check
oscilloscope
BD board
a“
TP (FEQ) ©
TP (VC)
Procedure :
1. Connect oscilloscope to test point TP (FEO) on BD board.
2. Connect between test point TP (FES) and TP (VC) by lead wire.
3. Turned Power switch on and actuate the focus serch. (actuate
the focus serch when disc table is moving in and out.)
Check the oscilloscope waveform (S curve) is symmetrical
between A and B. And confirm peak to peak level within
341 Vp-p.
4.
S curve waveform symmetry
within 3£1Vp-p
5. After check, remove the lead wire connected in step 2.
Note: » Try to measure several times to make sure that the
ratio of A: B or B: A is more than 10: 7.
° Take sweep time as long as possible and light up the
brightness to obtain best waveform.

Procedure :
1. Connect oscilloscope to test point TP (RFO) on BD board.
2. Turn Power switch on.
3. Put disc (YEDS-18) in and playback.
4. Confirm that oscilloscope waveform is clear and check RF
signal level is correct or not.
Note :
Clear RF signal waveform means that the shape “ 0” can be clearly
distinguished at the center of the waveform.

2. Turn Power switch on.
3. Confirm that reading on frequency counter is 4.3218MHz.
Focus/Tracking Gain
This gain has a margin, so even if it is slightly off.
There is no problem.
Therefore, do not perform, this adjustment.
Please note that it should be fixed to mechanical center position when
you moved and do not know original position.
