SERVICING NOTICES ON CHECKING
As for the places which need special attentions,
they are indicated with the labels or seals on the
cabinet, chassis and parts. Make sure to keep the
indications and notices in the operation manual.
2. AVOID AN ELECTRIC SHOCK
There is a high voltage part inside. Avoid an
electric shock while the electric current is
flowing.
3. USE THE DESIGNATED PARTS
The parts in this equipment have the specific
characters of incombustibility and withstand
voltage for safety. Therefore, the part which is
replaced should be used the part which has
the same character.
Especially as to the important parts for safety
which is indicated in the circuit diagram or the
table of parts as a mark, the designated
parts must be used.
4. PUT PARTS AND WIRES IN THE
ORIGINAL POSITION AFTER
ASSEMBLING OR WIRING
There are parts which use the insulation
material such as a tube or tape for safety, or
which are assembled in the condition that
these do not contact with the printed board.
The inside wiring is designed not to get closer
to the pyrogenic parts and high voltage parts.
Therefore, put these parts in the original
positions.
5. TAKE CARE TO DEAL WITH THE
CATHODE-RAY TUBE
In the condition that an explosion-proof cathoderay tube is set in this equipment, safety is
secured against implosion. However, when
removing it or serving from backward, it is
dangerous to give a shock. Take enough care to
deal with it.
6. AVOID AN X-RAY1. KEEP THE NOTICES
Safety is secured against an X-ray by considering about the cathode-ray tube and the high
voltage peripheral circuit, etc.
Therefore, when repairing the high voltage peripheral circuit, use the designated parts and
make sure not modify the circuit.
Repairing except indicates causes rising of high
voltage, and it emits an X-ray from the cathoderay tube.
PERFORM A SAFETY CHECK AFTER
7.
SERVICING
Confirm that the screws, parts and wiring which
were removed in order to service are put in the
original positions, or whether there are the
portions which are deteriorated around the
serviced places serviced or not. Check the
insulation between the antenna terminal or
external metal and the AC cord plug blades.
And be sure the safety of that.
(INSULATION CHECK PROCEDURE)
1.
Unplug the plug from the AC outlet.
2.
Remove the antenna terminal on TV and turn
on the TV.
3.
Insulation resistance between the cord plug
terminals and the eternal exposure metal
[Note 2] should be more than 1M ohm by
using the 500V insulation resistance meter
[Note 1].
4.
If the insulation resistance is less than 1M
ohm, the inspection repair should be
required.
[Note 1]
If you have not the 500V insulation
resistance meter, use a Tester.
[Note 2]
External exposure metal: Antenna terminal
Earphone jack
HOW TO ORDER PARTS
Please include the following informations when you order parts. (Particularly the VERSION LETTER.)
1. MODEL NUMBER and VERSION LETTER

DISASSEMBLY INSTRUCTIONS
1. 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. 1-1.)
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.
GND on the CRT
3. After one side is removed, pull in the opposite direction to
remove the other.
NOTE
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. 1-3.)
Location of Anode Cap

REMOVAL AND INSTALLATION OF
FLAT PACKAGE IC
REMOVAL
Put the Masking Tape (cotton tape) around the Flat
1.
Package IC to protect other parts from any damage.
(Refer to Fig. 2-1.)
NOTE
Masking is carried out on all the parts located within 10
mm distance from IC leads.
When IC starts moving back and forth easily after
3.
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. 2-3.)
NOTE
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.

Finally, confirm the soldering status on four sides of the IC
5.
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, always be sure to replace the IC in this
case.

ELECTRICAL ADJUSTMENTS
1. ADJUSTMENT PROCEDURE
Read and perform these adjustments when repairing the
circuits or replacing electrical parts or PCB assemblies.
CAUTION
•
Use an isolation transformer when performing any service
on this chassis.
•
Before removing the anode cap, discharge electricity
because it contains high voltage.
•
When removing a PCB or related component, after
unfastening or changing a wire, be sure to put the wire
back in its original position.
•
When you exchange IC and Transistor for a heat sink,
apply the silicon grease on the contact section of the heat
sink. Before applying new silicon grease, remove all the
old silicon grease. (Old grease may cause damages to the
IC and Transistor.)

3. PURITY AND CONVERGENCE
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.
3-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT)
1.
Tighten the screw for the magnet. Refer to the adjusted
CRT for the position. (Refer to Fig. 3-1)
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.
3-2: PURITY
NOTE
Adjust after performing adjustments in section 3-1.
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.

DEFLECTION YOKE SCREW
MAGNET SCREW
3-3: STATIC CONVERGENCE
NOTE
Adjust after performing adjustments in section 3-2.
1.
Receive the crosshatch pattern from the color bar
generator.
2.
Combine red and blue of the 3 color crosshatch
pattern on the center of the screen by adjusting the pair
of 4 pole magnets.
3.
Combine red/blue (magenta) and green by adjusting the
pair of 6 pole magnets.
3-4: DYNAMIC CONVERGENCE
NOTE
Adjust after performing adjustments in section 3-3.
1.2.Adjust the differences around the screen by moving the
deflection yoke upward/downward and right/left.
(Refer to Fig. 3-2-a)
Insert three wedges between the deflection yoke and
CRT funnel to fix the deflection yoke.
