■ TO SERVICE PERSONNEL

1. Critical Components Information
Components having special characteristics are marked Z
and must be replaced with parts having specifications equal
to those originally installed.

2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.

● Meter impedance should be equivalent to 1500 ohms

shunted by 0.15µF.

● Leakage current must not exceed 0.5mA.

● Be sure to test for leakage with the AC plug in both

polarities.

THE DVD AUDIO/VIDEO PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIED
SERVICE PERSONNEL.

WARNING: CHEMICAL CONTENT NOTICE!

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or
plastic (where applicable) components may also contain traces of chemicals found by the California Health and
Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR
ANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes

DVR-C310

or expose eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands

before handling food.

WARNING: Laser Safety

This product contains a laser beam component. This component may emit invisible, as well as visible radiation,
which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must
be used during servicing of the unit.

1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from
the laser pick-up unit at all times. Do not stare at the laser beam at any time.

2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.

3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.

Laser Emitting conditions:

1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the "ON" position, the laser component will
emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through
the lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laser
emissions.

2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory
prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this
manual. Adjustment of this control can increase the laser emission level from the device.

Warning for power supply

The primary side of the power supply carries live mains voltage when the player is connected to the mains
even when the player is switched off !

This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing the player.
Service personnel have to take precautions to prevent touching this area or components in this area.

Note:
The screws on the DVD mechanism may never be touched, removed or re-adjusted.
Handle the DVD mechanism with care when the unit has to be exchanged!
The DVD mechanism is very sensitive for dropping or giving shocks.

■ PREVENTION OF ELECTROSTATIC DISCHARGE

The laser diode in the traverse unit (optical pickup) may be damaged due to static electricity from clothes or the human
body. Use caution to prevent electrostatic damage when servicing or handling the laser diode.

1. Grounding for electrostatic damage prevention

1. Worktable grounding
Put a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.

2. Human body grounding
Use an anti-static wrist strap to discharge the static electricity from your body.

Anti-static wrist strap

1MΩ

Conductive material
(sheet) or steel sheet

2. Handling of the optical pickup

1. To prevent damage to the optical pickup replacement parts during transportation and before installation, both ends
of the laser diode are short-circuited. After installing the new part, remove the short circuit according to the correct
procedure in this service manual.

2. Do not use a tester to check the laser diode in the optical pickup. The power supply in the tester will damage the
laser diode.

DVR-C310

3. Handling Precautions for the Traverse Unit (Optical Pickup)

1. Handle the traverse unit (optical pickup) gently, as it is an extremely high-precision assembly.

2. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable.

3. The semi-fixed resistor for laser power adjustment should not be adjusted. Do not turn the resistor.

● Preventive measure for laser diode from electrostatic breakdown

When replacing the MONO Board or DVD 5-disc changer module, solder between lands of
the optical pick up P.C.B. to protect the laser diode against electrostatic breakdown.

Notes

• Use an anti-static soldering iron to short-circuit and unshort­circuit laser diode.

• After you have finished repairing, remove the solder from the
