SECTION 1
DISASSEMBLY
1.1 SERVICE CAUTIONS
1.1.1 Precautions
1. Before disassembling/re-assembling the set as well as
soldering parts, make sure to disconnect the power
cable.
2. When disconnecting/connecting connectors, pay enough
attention to wiring not to damage it.
3. In general, chip parts such as resistor, shorting jumpers
(0-ohm resistor), ceramic capacitors, diodes, etc. can not
be reused after they were once removed.
4. When installing parts, be careful not to do with other parts
as well as not to damage others.
5. When removing ICs, be careful not to damage circuit
patterns.
6. Tighten screws properly during the procedures. Unless
specified otherwise, tighten screws at torque of 0.196 N·m
(2.0 kgf·cm).

1.5 REPLACEMENT OF CCD IMAGE SENSOR Notes:
•
Pay the most careful attention to the transparent glass
and optical LPF of the CCD image sensor so a not the
soil and damage them. If something is soiled with finger-prints, etc., gently clean it with silicon-processed
paper/cloth or chamois.
• When the CCD image sensor is shipped from the fac-
tory, there are protection seals applied onto the transparent glass. Leave the protector as it is, and take it off just
before assembling the CCD image sensor to the OP
block.
1.5.1 Removal of CCD image sensor
1. Remove two screws (1, 2) securing the CCD base assy,
and disassemble the CCD spacer, the optical LPF,
spacer rubber.
1.5.2 Installation of new CCD image sensor
1. Remove the protection seal from a new CCD image sensor. Next, put the optical LPF, spacer rubber, CCD spacer
on the CCD image sensor as they are piled up in this
order. At that time, make sure of orientation of each item
refering to the following table (see Fig. 1-5-1).
Part Name Orientation
CCD image sensor Mark is on the right viewed as indi-
cated by the arrow a .
Spacer rubber IC side is horizontal.
Optical LPF Marks are on the left and bottom
viewed as indicated by the arrow
a .
2. Fix the CCD base assy to OP block with the two screws
(1, 2) . At that time, be careful of the orientation.
3. After completion of all P.C. boards to the camera section, observe the monitor to confirm no vignetting caused
by the bodytube, rings, lens hood, etc. If no vignetting is
observed, it can be said that image's parallel, horizontality
and centering are correct.

1.6 TAKE OUT CASSETTE TAPE
In the event that the set enters the emergency mode as it is
loaded with a cassette tape and the cassette tape cannot
be ejected with the EJECT button, manually, take it out of
the set according to the following procedure.
Note:
If the mechanism comes into the unloading mode as
the cassette tape is not held by hand, it results in tape
damage.
1. Disconnect the set from the power source.
2. Remove the cassette cover assembly, Cover (VF), top
cover, (See Fig. C1, C2 and C3, Page 1-1, 2, 3 and 4)
3. Connect a jumper wire to each pole of the loading motor
as shown by the magnified view b (Fig. 1-6-1)
Battery
4. While holding down the cassette housing by hand, connect the jumper wires to a battery to run the mechanism
to the EJECT position four unloading. If this unloading
operation is performed as the cassette housing is not
held down by hand, the front lid of the cassette may
damage the tape when it is ejected.
5. For taking in the slack of the tape, run the mechanism
to the EJECT position as the front lid of the cassette is
left open, and turn the take-up gear in the forward direction to wind up the tape. After confirming that the tape
has completely been wound up and the supply reel is
idling, take the cassette tape out of the cassette housing.

2.4 TAPE TRANSPORT ADJUSTMENT
In most cases the deck section is in need electrical adjustment, it results from replacement of worm mechanical parts
or video heads. In the event of malfunction with electrical
circuits, troubleshouting with the aid of proper test instruments most be done first, and then commence necessary
repair, replacement and adjustment, etc.
2.4.1 Back tension
1. Set a cassette torque meter onto the deck and measure
the back tension in standard REC mode to confirm that
the back tension is 7 – 14 gf
•cm.
2. If not, replace the tension band.
When the value widely fluctuates in the measurement,
replace the supply reel disk.
3. With the cassette torque meter, confirm that the play
torque is 15 – 25 gf
•cm.
If necessary, replace the center pully unit.
8. When the FM waveform breaks in the level varying process, subtly adjust the height of guide rollers at every
breaking point so that the waveform varies as flat as possible.
Repeat the above steps 6. and 7. several times to confirm that the waveform is flat as a whole.
9. Playback the LP stairstep signal of alighment tape and
adjust the tracking control to maximize the FM waveform, confirm that FM waveform variation is always
flat.
10. Record the signal and play it back in both of the SP and
LP modes, and confirm that the FM waveform is flat in
both modes.
Note:
Among the above-mentioned adjustment steps,
the items of No. 9 and No. 10 are needed for the
LP model only.

2.5 REMARKS
2.5.1 Cleaning
1. For cleaning of the upper drum (particularly video heads),
use fine-woven cotton cloth or Kimwipe with alcohol
soaks through. Do not move the cloth but turn the upper
drum counterclockwise.
Make sure not to move the cloth in the vertical
Note:
direction to the video head, since it may cause
damage of the video heads.
2. For cleaning of parts of the tape transport system except
the upper drum, use fine-woven cotton cloth or cotton
swab soaked alcohol.
3. After cleaning, confirm that the cleaned parts are completely dry before loading the deck with cassette tape.
2.5.2 Applying oil and grease
1. Periodical oiling and greasing are not required but should
be done to new parts when replacing. If oil and grease
on the other parts of the other party are old and dirty,
wipe them clean and apply new oil or grease.
2. For parts and points to apply oil and grease, refer to the
exploded view of the mechanism assembly (M3).
Table 1-5-1 specifies oil and grease to be used.
3. When oiling, clean the objective parts with alcohol first
and apply one or two drop(s) of oil. Too much oiling
causes rotary parts to slip because of oil leakage.
