Maintenance of laser pickup

(1) Cleaning the pickup lens
Before you replace the pickup,please try to
clean the lens with a alcohol soaked cotton
swab.

(2) Life of the laser diode
When the life of the laser diode has expired.
the following symptoms will appear..
(1) The level of RF output (EFM output:amplitude
of eye patterrn) will be low.

KW-XC828

Is RF output

1.3 0.4Vp-p?

YES

O.K

(3) Semi-fixed resistor on the APC PC board
The semi-fixed resistor on the APC printed
circuit board which is attached to the pickup
is used to adjust the laser power.Since this.
adjustment should be performed to match the
characteristics of the whole optical block,
do not touch the semi-fixed resistor..
If the laser power is lower than the specified
value, the laser diode is almost worn out, and
the laser pickup should be replaced.
If the semi-fixed resistor is adjusted while
the pickup is functioning normally, the laser
pickup may be damaged due to excessive current.

NO

Replace it.

Replacement of laser pickup

Turn of the power switch and, disconnect the
power cord.

Replace the pickup with a normal one.(Refer
to "Pickup Removal" on the previous page)

Plug the power cord in, and turn the power on.
At this time, check that the laser emits for
about 3seconds and the objective lens moves
up and down.
Note: Do not observe the laser beam directly..

Play a disc.

Check the eye-pattern at TP1.

Finish.

Item

1.Head azimuth

Adjusting & Confirmation Methods

"Head Height Adjustment"
Note
Adjust the azimuth directly. When you adjust the height using a
mirror tape, remove the cassette housing from the mechanism
chassis. After installing the cassette housing, perform the azimuth
adjustment.

1. load the mirror tape (SCC-1659). Adjust with height adjustment
screw A and azimuth adjustment screw B so that line "A" of
the mirror tape runs in the center between Lch and Rch in the
reverse play mode.

2. After switching from REV to FWD then to REV, check that the
head position set in procedure "1" is not changed.
*If the position has shifted, adjust again and check.

3. Adjust the azimuth screw B so that line "B" of the mirror tape
runs in the center between Lch and Rch in the forward play
mode.

"Head Azimuth Adjustment"

1. Load the test tape (VT724: 1kHz) and play it back in the
reverse play mode. set the Rch output level to maximum.

2. Load the test tape (VT703: 10kHz) and play it back in the
forward play mode. Adjust the Rch and Lch output levels to
maximum, with azimuth adjustment screw B .
In this case, the phase difference should be within 45 .

3. Engage the reverse mode and adjust the output level to
maximum, with azimuth adjustment screw C .

4. When switching between forward and reverse modes, the
difference between channels should be within 3dB.
*Between FWD Lch and Rch, REV Lch and Rch.

5. When the test tape (VT721 (315Hz )) is played back, the level
difference between channels should be within 1.5dB.

0.35% (JIS RMS).

2. In case of out of specification, adjust the motor with a built-in
volume resistor.

1. Play the test tape (VT724 : 1kHz) back.

2. Adjust the VR191 (Lch) and VR291 (Rch) so that the DOLBY NR
