DISASSEMBLY INSTRUCTIONS
3. After one side is removed, pull in the opposite direction to
remove the other.
3. REMOVAL OF ANODE CAP
Read the following NOTED items before starting work.
NOTE
* 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.
Take care not to damage the Rubber Cap.
INSTALLATION
1. Clean the spot where the cap was located with a small
amount of alcohol. (Refer to Fig. 3-3.)
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.
Location of Anode Cap
GND on the CRT
Fig. 3-3
NOTE
Confirm that there is no dirt, dust, etc. at the spot where
the cap was located.
2. Arrange the wire of the Anode Cap and make sure the
wire is not twisted.
3. Turn over the Rubber Cap. (Refer to Fig. 3-4.)

3. When IC starts moving back and forth easily after
desoldering completely, pickup the corner of the IC using
a tweezers and remove the IC by moving with the IC
desoldering machine. (Refer to Fig. 4-3.)
4. REMOVAL AND INSTALLATION OF
FLAT PACKAGE IC
REMOVAL
NOTE
1. Put the Masking Tape (cotton tape) around the Flat
Package IC to protect other parts from any damage.
(Refer to Fig. 4-1.)
Some ICs on the PCB are affixed with glue, so be
careful not to break or damage the foil of each IC
leads or solder lands under the IC when removing it.
NOTE
Masking is carried out on all the parts located within
10 mm distance from IC leads.

4. Peel off the Masking Tape.
NOTE
5. Absorb the solder left on the pattern using the Braided
Shield Wire. (Refer to Fig. 4-4.)
Do not add the rotating and the back and forth
directions force on the IC, until IC can move back and
forth easily after desoldering the IC leads completely.
NOTE
Do not move the Braided Shield Wire in the vertical

INSTALLATION
4. When bridge-soldering between terminals and/or the
soldering amount are not enough, resolder using a Thintip Soldering Iron. (Refer to Fig. 4-8.)
1. Take care of the polarity of new IC and then install the
new IC fitting on the printed circuit pattern. Then solder
each lead on the diagonal positions of IC temporarily.
(Refer to Fig. 4-5.)

5. Finally, confirm the soldering status on four sides of the
IC using a magnifying glass.
Confirm that no abnormality is found on the soldering
position and installation position of the parts around the
IC. If some abnormality is found, correct by resoldering.

NOTE
When the IC leads are bent during soldering and/or
repairing, do not repair the bending of leads. If the
bending of leads are repaired, the pattern may be
damaged. So, be always sure to replace the IC in this
case.

CLEANING
2. TAPE RUNNING SYSTEM
NOTE
When cleaning the tape transport system, use the
gauze moistened with isopropyl alcohol.
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.
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.)
1. AUDIO CONTROL HEAD
Clean the Audio Control Head with the cotton stick
soaked by alcohol. Clean the full erase head in the
same manner. (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.

PREPARATION FOR SERVICING
How to use the Servicing Fixture
1. Unplug the connector CP351, CP757 and CP302 then remove the TV/VCR Block from the set.
2. Unplug the connector CP810, CP820 and CP850, then remove the Main PCB from the VCR Block.
3. Connect as shown in the below figure using the Service Fixture.
• Connect the Syscon PCB to the Main PCB with the cable JG162C and JG162D.
• Connect the Syscon PCB to the CRT PCB with the cable JG162Y.
4. Remove the Operation PCB from the set, then connect it with the Syscon PCB.
If necessary, connect CP351.
5. Short circuit between TP1001 and Ground with the cable JG154.
(Refer to MAJOR COMPONENTS LOCATION GUIDE)

POST POSITION
1. CONFIRMATION AND ADJUSTMENT
Read the following NOTES before starting work.
1. Set to the PLAY mode.
2. 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.
3. While turning the S Reel clockwise, confirm that the
edge of the Tension Arm is located in the position
described above.
• 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 GND. (Refer to
ELECTRICAL ADJUSTMENT PARTS LOCATION
GUIDE) In this condition the BOT/EOT/Reel Sensor will
not function.
