LASER BEAM CAUTION LABEL

When the power supply is being turned on, you may not remove this laser beam caution label. If it removes, radiation of a

laser may be received.

PREPARATION OF SERVICING

Pickup Head consists of a laser diode that is very susceptible to external static electricity.

Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement,
its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire, etc. to
protect the laser diode from damage by static electricity.

And also, the LSI and IC are same as above.

W

The ground resistance
between the ground line
and the ground is less than 10W.

SAFETY NOTICE

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 RECORDER

power plug reversed.

NEVER RETURN A DVD VIDEO RECORDER TO THE

CUSTOMER WITHOUT TAKING NECESSARY

CORRECTIVE ACTION.

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.

PART REPLACEMENT AND

ADJUSTMENT PROCEDURES

CAUTIONS BEFORE STARTING PART REPLACEMENT

Electronic parts are susceptible to static electricity and may be easily damaged, so do not forget to ground as required.

Many screws are used inside the unit. To prevent the screws from missing or dropping, etc. 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.

Waveform and Voltage Measurement

• The waveforms for CD/DVD and RF shown in the circuit diagrams are obtained when a test disc is played back.

• All voltage values except the waveforms are expressed in DC and measured by a digital voltmeter.

Others

• The parts indicated with "NC" or "KETU" etc. are not used in the circuits of this model.

1-2. Precautions for Part Replacement

• In the schematic diagram, parts marked (ex. F801) are critical part to meet the safety regulations, so always use

the parts bearing specified part codes (SN) when replacing them.

• Using the parts other than those specified shall violate the regulations, and may cause troubles such as operation

failures, fire etc.
