ORIGINAL
MFR’S VERSION A
Design and specifications are subject to change without notice.
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
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.
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.
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.

WHEN REPLACING DVD DECK
[ Removing the DVD Deck ]
Before removing Pick Up PCB and DVD PCB connector, short circuit the position shown in Fig. 1
using a soldering iron. If you remove the DVD Deck with no soldering, the Laser may be damaged.
[ Installing the DVD Deck ]
Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD
PCB connector.
NOTE
Before your operation, please read “PREPARATION OF SERVICING”.
•
Use the Lead Free solder.
•
Manual soldering conditions
•
• Soldering temperature: 320 ± 20˚C
• Soldering time: Within 3 seconds
• Soldering combination: Sn-3.0Ag-0.5Cu
When Soldering/Removing of solder, use the drawing equipment over the Pick Up Unit to keep the
•
Flux smoke away from it.
Pick Up PCB
Short circuit using a
soldering iron.
Fig. 1
PREPARATION OF SERVICING
The laser diode used for a pickup head may be destroyed with external static electricity.
Moreover, even if it is operating normally after repair when static electricity discharge is received
at the time of repair, the life of the product may be shortened.
Please perform the following measure against static electricity, be careful of destruction of a
laser diode at the time of repair.
• Place the unit on a workstation equipped to protect against static electricity, such as conductive
mat.
• Soldering iron with ground wire or ceramic type is used.
• A worker needs to use a ground conductive wrist strap for body.

4. 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. 4-1.)
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. 4-3.)
Location of Anode Cap

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.
