SERVICING NOTICES ON CHECKING

6. AVOID AN X-RAY1. KEEP THE NOTICES

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.

3. USE THE DESIGNATED PARTS

5. TAKE CARE TO DEAL WITH THE

CATHODE-RAY TUBE

In the condition that an explosion-proof cathode-

ray 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 consider-

ing about the cathode-ray tube and the high

voltage peripheral circuit, etc.

Therefore, when repairing the high voltage pe-

ripheral 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 cathode-

ray tube.

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

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)

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

Earphone jack

2. AVOID AN ELECTRIC SHOCK

There is a high voltage part inside. Avoid an

electric shock while the electric current is

flowing.

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.
