3. REMOVAL OF ANODE CAP

Read the following NOTED items before starting work.

After turning the power off there might still be a potential

*

voltage that is very dangerous. When removing the
Anode Cap, make sure to discharge the Anode Cap's
potential voltage.
Do not use pliers to loosen or tighten the Anode Cap

*

terminal, this may cause the spring to be damaged.

REMOVAL

1. Follow the steps as follows to discharge the Anode Cap.

(Refer to Fig. 3-1.)

Connect one end of an Alligator Clip to the metal part of a
flat-blade screwdriver and the other end to ground.
While holding the plastic part of the insulated Screwdriver,
touch the support of the Anode with the tip of the
Screwdriver.
A cracking noise will be heard as the voltage is discharged.

CLEANING

NOTE

After cleaning the heads with isopropyl alcohol, do not
run a tape until the heads dry completely. If the heads
are not completely dry and alcohol gets on the tape,
damage may occur.

1. AUDIO CONTROL HEAD

Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol and clean the audio control head by
wiping it horizontally. Clean the full erase head in the
same manner. (Refer to the figure below.)

2. TAPE RUNNING SYSTEM

When cleaning the tape transport system, use the
gauze moistened with isopropyl alcohol.

3. CYLINDER

Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol. Hold it to the cylinder head softly.
Turn the cylinder head counterclockwise to clean it (in
the direction of the arrow). (Refer to the figure below.)

NOTE

Do not exert force against the cylinder head. Do not move
the chamois upward or downward on the head.
Use the chamois one by one.

NOTE FOR THE REPLACING OF MEMORY IC

If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken to
ensure correct data settings while making reference to TABLE 1.

NOTE:

Initial Data setting will not be possible if clock has been set. To reset clock, either unplug AC cord and allow
at least 30 minutes before Power On or alternatively, discharge backup capacitor. No need the setting for after INI 3F.

MECHANICAL ADJUSTMENTS

1. CONFIRMATION AND ADJUSTMENT

Read the following NOTES before starting work.

••Place an object which weighs between 450g~500g on
the Cassette Tape to keep it steady when you want to
make the tape run without the Cassette Holder. (Do not
place an object which weighs over 500g.)
When you activate the deck without the Cassette
Holder, short circuit between TP1001 and TP1002. (Refer

to ELECTRICAL ADJUSTMENT PARTS LOCATION
GUIDE) In this condition the BOT/EOT/Reel Sensor will

not function.

CONFIRMATION AND ADJUSTMENT OF REEL

1-1:

DISK HEIGHT

1.

Turn on the power and set to the STOP mode.

2.

Set the master plane (JG022) and reel disk height
adjustment jig (JG024A) on the mechanism framework,
taking care not to scratch the drum, as shown in Fig. 1-
1-A.

3.

Confirm that "A" of the reel disk is lower than "B" of the
reel disk height adjustment jig (JG024A) , and is higher
than "C". If it is not enough height, adjust to 10(+0.2, -0)
mm with the height adjustment washer.

4.

Adjust the other reel in the same way.

Adjust the Tension Adjust until the edge of the Tension
Arm is positioning within 0.5mm range from the
standard line center of Main Chassis.
After this adjustment, confirm that the cut position is
located in "A" area as shown in Fig. 1-2-B. If it is
located in "B" area, adjust again.

ADJUSTMENTS

NOTE

1.

Turn the unit on and let it warm up for at least 30
minutes before performing the following adjustments.

2.

Place the CRT surface facing east or west to reduce the
terrestrial magnetism.

3.

Turn ON the unit and demagnetize with a Degauss Coil.

4-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT)

1.

Tighten the screw for the magnet. Refer to the adjusted
CRT for the position. (Refer to Fig. 4-1)
If the deflection yoke and magnet are in one body,
untighten the screw for the body.

2.

Receive the green raster pattern from the color bar
generator.

3.

Slide the deflection yoke until it touches the funnel side
of the CRT.

4.

Adjust center of screen to green, with red and blue on
the sides, using the pair of purity magnets.

5.

Switch the color bar generator from the green raster
pattern to the crosshatch pattern.

6.

Combine red and blue of the 3 color crosshatch
pattern on the center of the screen by adjusting the pair
of 4 pole magnets.

7.

Combine red/blue (magenta) and green by adjusting the
pair of 6 pole magnets.

8.

Adjust the crosshatch pattern to change to white by
repeating steps 6 and 7.

NOTE

Adjust after performing adjustments in section 4-1.

1.

Receive the green raster pattern from color bar
generator.

2.

Adjust the pair of purity magnets to center the color on
the screen.
Adjust the pair of purity magnets so the color at the
ends are equally wide.

3.

Move the deflection yoke backward (to neck side)
slowly, and stop it at the position when the whole screen
is green.

4.

Confirm red and blue color.

5.

Adjust the slant of the deflection yoke while watching
the screen, then tighten the fixing screw.
