Please heed the points listed below during servicing and inspection.

Heed the cautions!

Spots requiring particular attention when servicing, such as

the cabinet, parts, chassis, etc., have cautions indicated on

labels or seals. Be sure to heed these cautions and the cau-

tions indicated in the handling instructions.

Caution concerning electric shock!

(1) An AC voltage is impressed on this set, so touching inter-

nal metal parts when the set is energized could cause

electric shock. Take care to avoid electric shock, by for ex-

ample using an isolating transformer and gloves when

servicing while the set is energized, unplugging the power

cord when replacing parts, etc.

(2)There are high voltage parts inside. Handle with extra care

when the set is energized.

Caution concerning disassembly and assembly!

Though great care is taken when manufacturing parts from

sheet metal, there may in some rare cases be burrs on the

edges of parts which could cause injury if fingers are moved

across them. Use gloves to protect your hands.

Only use designated parts!

The set's parts have specific safety properties (fire resis-

tance, voltage resistance, etc.). For replacement parts, be

sure to use parts which have the same properties. In particu-

lar, for the important safety parts that are marked ! on wiring

diagrams and parts lists, be sure to use the designated parts.

Be sure to mount parts and arrange the

wires as they were originally!

For safety reasons, some parts use tape, tubes or other insu-

lating materials, and some parts are mounted away from the

surface of printed circuit boards. Care is also taken with the

positions of the wires inside and clamps are used to keep

wires away from heating and high voltage parts, so be sure to

set everything back as it was originally.

Inspect for safety after servicing!

Check that all screws, parts and wires removed or discon-

nected for servicing have been put back in their original posi-

tions, inspect that no parts around the area that has been

serviced have been negatively affected, conduct an insulation

check on the external metal connectors and between the

blades of the power plug, and otherwise check that safety is

ensured.

(Insulation check procedure)

Unplug the power cord from the power outlet, disconnect the

antenna, plugs, etc., and turn the power switch on. Using a

500V insulation resistance tester, check that the insulation re-

sistance between the terminals of the power plug and the ex-

ternally exposed metal parts (antenna terminal, headphones

terminal, microphone terminal, input terminal, etc.) is 1M or

greater. If it is less, the set must be inspected and repaired.

Concerning important safety parts

Many of the electric and structural parts used in the set have

special safety properties. In most cases these properties are

difficult to distinguish by sight, and using replacement parts

with higher ratings (rated power and withstand voltage) does

not necessarily guarantee that safety performance will be pre-

served. Parts with safety properties are indicated as shown

below on the wiring diagrams and parts lists is this service

manual. Be sure to replace them with parts with the designat-

ed part number.

(1) Schematic diagrams ... Indicated by the ! mark.

(2) Parts lists ... Indicated by the ! mark.

Using parts other than the designated parts

could result in electric shock, fires or other

dangerous situations.

SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis

resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power

cord is less than 460 kohms, the unit is defective.

LASER RADIATION

Do not stare into beam or view directly with optical instruments, class 3A laser product.

CAUTION

DVD-2930/2930CI

WIRE ARRANGEMENT

If wire bundles are untied or moved to perform adjustment or

parts replacement etc., be sure to rearrange them neatly as

they were originally bundled or placed afterward.

Otherwise, incorrect arrangement can be a cause of noise

generation.

DIAGNOSTICS OF OPTICAL PICKUP

AND REPLACING TRAVERSE UNIT

Make failure diagnostics of the Optical Pickup as follows.

If the laser drive current (Iop) becomes more than 1.5 times of

the initial value, the Optical Pickup should be replaced.

The laser drive current initial value is checked by "Iop checked

Method" of next page.

In case of replacing the Pickup, change the whole part of the

Traverse Unit.

No mechanical adjustment is necessary after the replace-

ment.

1. Iop checked Method

Select the laser ON/OFF (CD/DVD) mode of the test mode,

and check the lop value of DVD laser or CD laser.

(See page 16 for test mode.)

1.1. DVD laser current check

(1) Press the SKIP REV or SKIP FWD button to display the

laser current value, and then select T22.

(2) Check the current value of Iop (nnnn).

( : Off, DVD laser, Initial value: mm.mm [mA],

Current value: nn.nn [mA])

1.2. CD Laser current check

(1) Press the SKIP REV or SKIP FWD button to display the

laser current value, and then select T21.

(2) Check the current value of Iop (nnnn).

The protection for the damage of laser diode.

If you want to change the optical device unit from any other

units, you must keep the following.

(1) It should be done at the desk already took measures the

static electricity in care of removing the OPU's (Optical

device unit) connector cable.

(2) Workers should be put on the "Earth Band".

(3) It should be done to add the solder to the short land to

prevent the broken Laser diode before removing the 24P

FFC cable.

(4) Don't touch OPU's connector parts carelessly.

3. Replacement of the Laser Pick-up

(Traverse Unit)

Check the Iop (Laser drive current)

If the present Iop (current) value exceeds.+150% of the ini-

tial value, replace the Traverse unit (Laser Pick-up) with a

new one.

ser current is displayed, then press the SKIP FWD or SKIP

REV button to select T23. (For details, see "Iop checked

For the DVD laser

( : Off, DVD laser, mm.mm [mA], nn.nn [mA])

Laser off

The laser turns off when the laser on/off mode is quit.

In the servo adjustment value display mode (See Table 1 - Servo adjustment value display mode details.)

(XXX : Selection mode, n: Adjustment value (HEX))
