-Safety Precautions

1. This design of this product contains special hardware and many circuits and components specially for safety
purposes. For continued protection, no changes should be made to the original design unless authorized in
writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Services
should be performed by qualified personnel only.

2. Alterations of the design or circuitry of the product should not be made. Any design alterations of the product
should not be made, Any design alterations or additions will void the manufacturers warranty and will further
relieve the manufacture of responsibility for personal injury or property damage resulting therefrom.

3. Many electrical and mechanical parts in the products have special safety-related characteristics. These
characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily
be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which
have these special safety characteristics are identified in the Parts List of Service Manual. Electrical
components having such features are identified by shading on the schematics and by (A) on the Parts List in
the Service Manual. The use of a substitute replacement which does not have the same safety characteristics
as the recommended replacement parts shown in the Parts List of Service Manual may create shock, fire, or
other hazards.

4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the like to be
separated from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of
electric shock and fire hazard. When service is required, the original lead routing and dress should be
observed, and it should be confirmed that they have been returned to normal, after re-assembling.

5. Leakage current check (Electrical shock hazard testing)

After re-assembling the product, always perform an isolation check on the exposed metal parts of the product

(antenna terminals, knobs, metal cabinet, screw heads, headphone jack, control shafts, etc.) to be sure the

product is safe to operate without danger of electrical shock.

Do not use a line isolation transformer during this check.

0 Plug the AC line cord directly into the AC outlet. Using a Leakage Current Tester", measure the leakage
current from each exposed metal parts of the cabinet, particularly any exposed metal part having a return
path to the chassis, to a known good earth ground. Any leakage current must not exceed 0.5mA AC (r.m.s.).

0 Alternate check method
Plug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 ohms per volt or more
sensitivity in the following manner. Connect a 1,500 Q10W resistor paralleled by a 0.1 511 F AC-type capacitor

between an exposed metal part and a known good earth ground. AC VOLTMETER
Measure the AC voltage across the resistor with the AC a (HavinglOOO
voltmeter. ohms/volts,

Move the resistor connection to each exposed metal part, more sen5"'v"y)

particularly any exposed metal part having a return path to
the chassis, and measure the AC voltage across the resistor.

0.1511 F AC TYPE

Now, reverse the plug in the AC outlet and repeat each I Plagethis
pro e on
measurement. Voltage measured any must not exceed 0.75 V 'WV . ~ each exposed

AC (r.m.s.).This corresponds to 0.5 mA AC (r.m.s.). 15009 10W metal part.

Good earth ground

1.This equipment has been designed and manufactured to meet international safety standards.
2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
3. Repairs must be made in accordance with the relevant safety standards.

4. It is essential that safety critical components are replaced by approved parts.

5. If mains voltage selector is provided, check setting for local voltage.

- Warning A CAUTION

Burrs formed during molding may
be left over on some parts of the
chassis. Therefore, pay attention to
such burrs in the case of
preforming repair of this system.

In regard with component parts appearing on the silk-screen printed side (parts side) of the PWB diagrams, the
parts that are printed over with black such as the resistor (I), diode (-) and ICP (.) or identified by the "A"
mark nearby are critical for safety.

When replacing them, be sure to use the parts of the same type and rating as specified by the manufacturer.
(Except the J and C version)

Adjustment method

(1) Initialization method

If microprocessor (IC401,IC402,|C403) or pick-up is replaces, initialize the
DVD player in the following matter

1)Take out the disc and close the tray.

2)Unplug the power plug.

3)lnsert power plug into outlet while pressing both PLAY button and OPEN/CLOSE button.
4)FL Display indicate "TEST * * ¥" . * * :Version, ¥:Region code

5)Press 3D-PHONIC key button of remote controller. and EEPROM initialize start.
6)When indicate "DTS" on the display, initialize finishes.

7)The power is turned OFF, and Unplug the power plug.

(2) Display of "Laser current value" and "Jitter value"

"Laser current value" and "Jitter value" are displayed on the FL display by the undermentioned
method. Please refer to the failure diagnosis.

1)Take out the disc and close the tray.
2)Unplug the power plug.
3)lnsert power plug into outlet while pressing both PLAY button and OPEN/CLOSE button.
4)FL Display indicate "TEST * * ¥" . * * :Version, ¥:Region code
5)Press the "OPEN/CLOSE" button to move the tray outward.
Put the test disc (VT-501) on the tray and press "OPEN/CLOSE" button.
The tray should move inward (NotezDon't push to close the tray directly by hand etc.)
6)Press the PLAY" button.
7)The laser current value and the jitter value is displayed on the FL indicator as follows.

The laser current value becomes 40mA for the above-mentioned.
Becomes a test mode by doing above-mentioned procedure 1) - 4). Afterwards, the laser current value can
be switched by pushing the key to remote control without turning on the disk.

Remote control "4" key Laser of CD *Returns to a usual test mode by the
Remote control "5" key Laser of DVD thing to push the stop button of
remote control.

If the laser current value is 64mA or less, it is roughly good. There is a possibility to which pick-up is
deteriorated, and exchange pick-up, please when there are 65mA or more laser current value.
