SAFETY-RELATED COMPONENT
WARNING!!
THE MARK FOUND ON SOME COMPONENT
PARTS INDICATES THE CRITICAL FOR RISK OF
FIRE AND ELECTRIC SHOCK.
WHEN REPLACING, BE SURE TO USE PARTS OF
IDENTICAL DESIGNATION.
MAKE LEAKAGE-CURRENT OR RESISTANCE
MEASUREMENTS TO DETERMINE THAT EXPOSED
PARTS ARE ACCEPTABLY INSULATED FROM THE
SUPPLY CIRCUIT BEFORE RETURNING THE
APPLIANCE TO THE CUSTOMER.

SERVICE NOTE
PRECAUTIONS
1. Ground for the work-desk.
Place a conductive sheet such as a sheet of copper (with impedance lower than 10Mohm) on the work-desk and
place the set on the conductive sheet so that the chassis.
2. Grounding for the test equipments and tools.
Test equipments and toolings should be grounded in order that their ground level is the same the ground of the power source.
3. Grounding for the human body.
Be sure to put on a wrist-strap for grounding whose other end is grounded.
Be particularly careful when the workers wear synthetic fiber clothes, or air is dry.
4. Select a soldering iron that permits no leakage and have the tip of the iron well-grounded.
5. Do not check the laser diode terminals with the probe of a circuit tester or oscilloscope.

1. Replacing the fuses
This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse , For fuse rating, refer to
the marking adjust to the symbol.
Ce symbole indique que le fusible utilise est e lent.
Pour une protection permanente, n'utiliser que des fusibles de meme
type. Ce demier est indique la qu le present symbol est apposre.

2. Safety-check out
(Only U.S.A. model)
After correcting the original service problem perform the
following safety check before releasing the set to the customer
Connect the insulating-resistance tester between the plug of
power supply cord and terminal GND on the back panel.
Specifications: More than 10M ohm at 500V
LASER CAUTION
The lightning flash with arrowhead symbol, within an equilateral triangle, is
intended to alert the user to the presence of uninsulated "dangerous voltage"
within the product's enclosure that may be of sufficient magnitude to constitute
a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user
to the presence of important operating and maintenance (servicing) instruction
in the literature accompanying the appliance.
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN
WARNING :
OR MOISTURE. DANGEROUS HIGH VOLTAGES ARE PRESENT INSIDE THE ENCLOSURE. DO NOT OPEN THE
CABINET. REFER SERVICING TO QUALIFIED PERSONNEL ONLY.
CAUTION :
TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT.
POUR EVITER LES CHOCS ELECTRIQUE, INTRODUIRE LA LAME LA PLUS LARGE DA LA FICHE DANS LA
ATTENTION :
BORNE CORRESPONDANTE DA LA PRISE ET POUSSER JUSQU' AU FOND.
Initialization of setup
1. Press the "DISC 4" and "CDPLAY" key to the same timing.
The "DISC 4 key is pushed previously.
Then, light off the FL tube.
2. Push the power switch.

DISASSEMBLY PROCEDURE
Replacement of DVD mechanism
The laser diode in the optical pickup block so
sensitive to static electricity, surge current and
etc..
That the components are liable to be broken down
or its reliability remarkable deteriorated.
During repair, carefully take the
following precautions.
Do not touch the optical
pickup object lens with the
hands.
Short Land
1. Remove the top cover with six screws.
2. Remove the tray.
3. Remove the roulette assembly.
4. Remove the roulette. (Roulette is removed as written below.)
5. Solder the LD output lands on the DVD optical pickup.
Please perform right photo to reference.
6. Replace the pickup mechanism assembly etc. . After unsolder the laser diodes
output lands.
DPC-5.2
Remove the roulette
1. Pull out the tray.
2. Stops in the position (cut deeply).
3. Remove in the direction of arrow.
4. Reassembly is performed by 3 to 1.
