SAFETY PRECAUTIONS
LEAKAGE CURRENT CHECK
Plug the AC line cord directly into a 120V AC outlet (do
not use an isolation transformer for this check). Use an
AC voltmeter, having 5000 Ω per volt or more sensitivity.
Connect a 1500 Ω 10 W resistor, paralleled by a 0.15 µF
150V AC capacitor between a known good earth ground
(water pipe, conduit, etc.) and all exposed metal parts of
cabinet (antennas, handle bracket, metal cabinet
screwheads, metal overlays, control shafts, etc.).
READING SHOULD NOT EXCEED 0.3V
Measure the AC voltage across the 1500 Ω resistor.
The test must be conducted with the AC switch on and
then repeated with the AC switch off. The AC voltage
indicated by the meter may not exceed 0.3 V. A reading
exceeding 0.3 V indicates that a dangerous potential
exists, the fault must be located and corrected.
Repeat the above test with the DVD VIDEO PLAYER
power plug reversed.
NEVER RETURN A DVD VIDEO PLAYER TO THE
CUSTOMER WITHOUT T AKING NECESSAR Y
CORRECTIVE ACTION.

SAFETY NOTICE
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) instructions in the
literature accompanying the appliance.
LASER BEAM CAUTION LABEL
When the power supply is turned on, you may not remove this laser caution label. If it is removed, laser radiation
may be recceived.

1. PREPARATION FOR SERVICING
The Pickup Head consists of a laser diode that is very susceptible to external static electricity.
Although it may operate properly after replacement, if subjected to electrostatic discharge during replacement,
its life might be shortened. When replacing the laser diode, LSI's and IC's, use a conductive mat, soldering iron
with ground wire, etc. to protect against damage from static electricity.

SECTION 2
PART REPLACEMENT AND
ADJUSTMENT PROCEDURES
CAUTIONS BEFORE STARTING SERVICING
Electronic parts are susceptible to static electricity and may easily damaged, so do not forget to take a proper grounding
treatment as required.
Many screws are used inside the unit. To prevent missing, dropping, etc. of the screws, always use a magnetized screwdriver in servicing. Several kinds of screws are used and some of them need special cautions. That is, take care of the
tapping screws securing molded parts and fine pitch screws used to secure metal parts. If they are used improperly, the
screw holes will be easily damaged and the parts can not be fixed.
