1. IMPORTANT SERVICE NOTES

BEFORE RETURNING THE VCR/DVD COMBINA­TION MODEL

Before returning the video cassette recorder to the user,
perform the following safety checks.

1. Inspect all lead dress to make certain that leads are
not pinched or that hardware is not lodged between
the chassis and other metal parts in the VCR/DVD
combination model.

2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustment and compartment covers or shields, isola­tion resistor/capacitor networks, mechanical insula­tors etc.

3. To be sure that no shock hazard exists, check for
current in the following manner.

● Plug the AC line cord directly into a 120 volt AC outlet
(Do not use an isolation transformer for this test).

● Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in series with
all exposed metal cabinet parts and a known earth
ground, such as a water pipe or conduit.

● Use an SSVM or VOM with 1000 ohm per volt, or
higher, sensitivity or measure the AC voltage drop
across the resistor (See Diagram).

● Move the resistor connection to earth exposed metal
part having a return path to the chassis (antenna,
metal cabinet, screw heads, knobs and control shafts,

etc.) and measure the AC voltage drop across the
resistor. Reverse the AC plug on the set and repeat
AC voltage measurements for each exposed part.
Any reading of 0.45V rms (this corresponds to 0.3mA
rms AC.) or more is excessive and indicates a poten­tial shock hazard which must be corrected before
returning the VCR/DVD combination model to the
owner.

1. NOTES DE SERVICE IMPORTANTES

AVANT DE RENDRE LE VCR/DVD MAGNETOSCOPE
Avant de rendre le magnétoscope à l’utilisateur, effectuer

les vérifications de sécurité suivantes.

1. Vérifier toutes les gaines de fil pour être sûr que les fils
ne sont pas pincés ou que le matériel n’est pas coincé
entre le châssis et les autres pièces métalliques dans
le VCR/DVD magnétoscope.

2. Vérifier tous les dispositifs de protection tels que les
boutons de commande non métalliques, les matériaux
d’isolement, le dos du coffret, les couvercles de
compartiment et ajustement ou les boucliers, les
réseaux de résistance / condensateur d’isolement, Ies
isolateurs mécaniques, etc.

3. Pour être sûr qu’il n’y a aucun risque de choc électrique,
vérifier le courant de fuite de la maniére suivante.

● Brancher le cordon d’alimentation secteur directement
dans une prise de courant de 120 volts. (Ne pas utiliser
de transformateur d’isolement pour cet essai).

● Utiliser deux fils à pinces et connecter une résistance
de 10 watts 1,5 kohm en parallèle avec un condensateur
de 0,15 µF en série avec des pièces du coffret
métallique exposées et une masse de terre connue
telle qu’un tuyau ou un conduit d’eau.

● Utiliser un VTVM ou VOM avec une sensibilité de 1000
ohms par volt ou plus ou mesurer la chute de tension
CA entre la résistance (voir diagramme).

● Déposer la connexion de la résistance à toutes les

pièces métalliques exposées ayant un parcours de
retour au châssis (connexions d’antenne, coffret
métallique, tétes de vis, boutons et arbres de
commande, etc.) et mesurer la chute de tension CA
entre la résistance. Inverser la fiche CA (une fiche
intermédiaire non polarisée doit être utilisée à seule fin
de faire ces vérifications.) sur l’appareil et répéter les
mesures de tension CA pour chaque piéce métallique
exposée. Toute lecture de 0,45 Vrms (ceci correspond
à 0,3 mArms CA) ou plus est excessive et signale un
danger de choc qui doit être corrigé avant de rendre le
VCR/DVD magnétoscope à son utilisateur.

7-4. SIGNALS OF PICKUP

7-4-1. Tracking drive signal (TR+, TR-)

The signal drives the tracking servo mechanism which projects the beam on the track by moving the objective lens (OL) to the outer
or inner circumference (at a right angle against the track) of the disk.

7-4-2. Focus drive signal (FO+, FO-)

The signal drives the focus servo mechanism which aligns the focus on the pit of the disk
by elevating OL (vertically against the disk surface.)

The VR terminal is connected to GND.

7-4-3. Monitor Diode (PD)

Since the laser diode largely varies output of the laser light even if the flowing current is slightly varied, the projection
light is detected with the monitor diode to control the laser light to be equally output.
Since the current varies on the monitor diode according to the intensity of the received light of the laser diode, the drive current of
the laser diode is reduced if the current of the monitor diode increases. On the contrary, the drive current of the laser diode is increased
if the current of the monitor diode decreases.
As the projection light of the laser diode becomes stronger, the current of the monitor diode increases to increase the current which
flows into the monitor diode output (PD). This is input to the pin 44 of IC301 and is compared with the reference voltage to control
the drive current of the laser diode.
The circuit is called ALPC (Automatic Laser Power Control).

LD

PD

When the quantity of laser light increases, the
current shown in figure increases and the PD
terminal voltage rises.

7-4-4. Laser diode drive current control (LD)

Power supply to drive the laser diode

IC301 is used to control. The LD terminal voltage
lowers, and the quantity of light reduces. (IC301 is
actuated by voltage input.)

7-4-5. High-frequency convolution module power supply (VOSC)

The high-frequency convolution imposes the high-frequency signal on the DC current to impose the high frequency on the drive
current of the laser. Thus, the interference of outgoing light and reflected light is prevented.

8. ADJUSTMENT, REPLACEMENT AND ASSEMBLY OF MECHANICAL UNITS

The explanation given below relates to the on-site general service (field service) but it does not relates to the adjustment
and replacement which need high-grade equipment, jigs and skill. For example, the drum assembling, replacement and
adjustment service must be performed by the person who have finished the technical courses.

8-1 MECHANISM CONFIRMATION ADJUSTMENT JIG

So as to perform completely the mechanism adjustment prepare the following special jigs. So as to maintain the initial
performance of the machine the maintenance and check are necessary. Utmost care must be taken so that the tape is
not damaged. If adjustment needs any jig, be sure to use the required jig.

5 Press the tracking button (+), (–) and change the

ATR signal waveform from max to min and from min
to max. At this time make sure that the ATR signal
waveform changes nearly parallel.

6 Unless the ATR signal waveform changes nearly

parallel, adjust the height of supply side and take-up
side guide roller so that the envelope waveform
changes nearly parallel. (For ATR signal adjustment
procedure refer to Figure 8-31.)

7 Turn the tilt screw to remove the tape crease at the

fixing guide flange.
Playback the tape and check for tape crease at the
fixing guide flange.
(1)If there is no tape crease

Turn the tilt screw clockwise so that tape crease
appears once at the flange, and then return the tilt
screw so that the crease disappears.

(2)If there is tape crease

Turn counterclockwise the tilt screw so that the
tape crease disappears.
(Reference) If the tilt screw is turned clockwise
crease appears at the lower flange.

Notes:

1. Previously set the tracking control in the center position,
and adjust the ATR signal waveform to maximum with X
value adjustment nut. Thereby the tape run rough ad­justment is facilitated.

2. Especially the outlet side ATR signal waveform must
have higher flatness.

Figure 8-28.

2. Adjustment of A/C head height and azimuth
1 Perform the initial setting of A/C head position by the

method stated in "8-17 Replacement 3".

2 Connect the oscilloscope to the audio output termi-

nal.

3 Using the alignment tape in which 1 kHz linear audio

signal has been recorded, adjust the height screw so
as to get max audio output.

4 Using the alignment tape in which 7 kHz linear audio

signal has been recorded, adjust the azimuth screw
so as to get max audio output.

5 The adjustment of 3 and 4 twice or three times

repeat, and finally adjust 4.

3 Next, press the tracking button (+), (–) and change

the ATR signal waveform from max to min and from
min to max. At this time adjust the height of supply
and take-up side guide roller with the adjustment
driver (JiGDRiVERH-4) so that the ATR signal wave­form changes nearly parallel.

4 If the tape is lifted or sunk from the helical lead

surface, the PB ATR signal waveform appears as
shown in Figure 8-31.

5 Press the tracking button (+), (–) and make sure that

the ATR signal waveform changes nearly parallel.

6 Finally, check tape crease near the reverse guide. If

tape crease is found, adjust tilt screw 45˚ counter
clockwise. Small tape crcase will appear at retain
guide after this adjustment finished.

Tentatively fix A/C head arm screws 1 by the method
described in "8-17 Replacement 3".
Playback the alignment tape (VROATSV) and
shortcircuit between TP801 and TP802. As a result
the auto-tracking is automatically cancelled, so that
the X value adjustment mode is set.
Move the A/C head with the X value adjustment gear
driver (JiGDRiVER-6) by the method shown in Fig-
ure 8-34, and adjust the A/C head so as to get the
maximum ATR signal waveform. (Note: When the A/
C head is adjusted, adjust so that the maximum ATR
signal waveform is obtained nearest the position of
initial setting made in 8-17.)

3 Move the A/C head with the X value adjustment gear

driver by the method shown in Figure 8-34, and
adjust the A/C head so as to get the maximum ATR
signal waveform. (Note: At this time adjust so as to
get the maximum ATR signal waveform nearest the
A/C head position which has been set in case of X
value rough adjustment as stated in 8-19, 3-2.)

4 Adjust the playback switching point (Refer to the

electric adjustment method.)

5 Playback the self-picture-recorded tape, and check

the flatness of ATR signal waveform and sound.
