6. AVOID AN X-RAY1. KEEP THE NOTICES

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.

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.

Inferior silicon grease can damage IC's and transistors.
When replacing an IC's or transistors, use only specified silicon grease (YG6260M).
Remove all old silicon before applying new silicon.

IMPORTANT

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.

PUT PARTS AND WIRES IN THE
ORIGINAL POSITION AFTER
ASSEMBLING OR WIRING

4.

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.

7.PERFORM A SAFETY CHECK AFTER
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.

2.

3.

4.

Unplug the plug from the AC outlet.
Remove the antenna terminal on TV and turn
on the TV.
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].
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

Please include the following informations when you order parts. (Particularly the VERSION LETTER.)

1. MODEL NUMBER and VERSION LETTER
The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be

found at the end of the SERIAL NUMBER.

2. PART NO. and DESCRIPTION
You can find it in your SERVICE MANUAL.

HOW TO ORDER PARTS

PCBs (manufactured) using lead free solder will have a PbF printing on the PCB.
(Please refer to figures.)

Caution:

Pb free solder has a higher melting point than standard solder;
Typically the melting point is 86°F~104°F(30°C~40°C) higher.
Please use a soldering iron with temperature control and adjust it to 650°F ± 20°F (350°C ± 10°C).
In case of using high temperature soldering iron, please be careful not to heat too long.
Pb free solder will tend to splash when heated too high (about 1100°F/ 600°C).
All products with the printed circuit board with PbF printing must be serviced with lead free solder.
When soldering or unsoldering, completely remove all of the solder from the pins or solder area,
and be sure to heat the soldering points with the lead free solder until it melts sufficiently.

Distinction of PbF PCB:

Recommendations

Recommended lead free solder composition is Sn-3.0Ag-0.5Cu.

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.

Flip up the sides of the Rubber Cap in the direction of the
arrow and remove one side of the support.

(Refer to Fig. 1-2.)

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

NOTE

Confirm that there is no dirt, dust, etc. at the spot where
the cap was located.

2.3.Arrange the wire of the Anode Cap and make sure the
wire is not twisted.
Turn over the Rubber Cap. (Refer to Fig. 1-4.)

4. Insert one end of the Anode Support into the anode button,
then the other as shown in Fig. 1-5.

5.6.Confirm that the Support is securely connected.
Put on the Rubber Cap without moving any parts.

NOTE

REMOVAL AND INSTALLATION OF
FLAT PACKAGE IC

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.

Blower type IC

IC

Heat the IC leads using a blower type IC desoldering
machine. (Refer to Fig. 2-2.)

2.

Fig. 2-2

NOTE

Do not rotate or move the IC back and forth until IC
can move back and forth easily after desoldering the
leads completely.

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. 2-3.)
