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.

Be sure to test for leakage current with the AC plug in both polarities, in addition, in each power ON, OFF and STANDBY

mode, if applicable.

CAUTION

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. be sure to heed these causions and the cautions indicated in the handling instructions.

◎Caution concerning electric shock!

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

internal metal parts when the set is energized could

cause electric shock. Take care to avoid electric

shock, by for example using an isolating transformer and gloves when servicing while the set is energized, unplugging the power cord when replacing parts, etc.

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

care when the set is energized.

◎ Caution concerning disassembly and

assembly!

Through 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 ngers

are moved across them. Use gloves to protect your hands.

◎Only use designated parts!

The set's parts have specific safety properties (fire

resistance, voltage resistance, etc.). For replacement parts, be sure to use parts which have the same poroperties. In particular, for the important safety parts that are marked z 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 seasons, some parts use tape, tubes or other insulating materials, and some parts are mounted away from the surface of printed circuit boards. Care is also taken with the positions of the wores omsode amd 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 disconnected for servicing have been put back in their original positions, inspect that no parts around the area that has been serviced have been negatively affected, conduct an inslation 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 inplug and the externally exposed metal parts (antenna terminal, headphones terminal, input terminal, etc.) is

1MΩ or greater. If it is less, the set must be inspected and

repaired.

CAUTION

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 poreserved. 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 designated part number.

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

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

Using parts other than the designated

parts could result in electric shock, res

or other dangerous situations.

NOTE FOR SCHEMATIC DIAGRAM

NOTE FOR PARTS LIST

WARNING:

Parts indicated by the z mark have critical characteristics. Use ONLY replacement parts recommended by the manufacturer.

CAUTION:

Before returning the set to the customer, be sure to carry out 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 set is defective.

WARNING:

DO NOT return the set to the customer unless the problem is identied and remedied.

WARNING AND LASER SAFETY INSTRUCTIONS

WARNING

All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wrist wrap with resistance. Keep components and tools also at this potential.

ATTENTION

WARNUNG

WAARSCHUWING

AVVERTIMENTO

Alle IC’s en vele andere halfgeleiders zijn gevoelig voor elektrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

Tous les IC et beaucoup d’autres semiconducteurs sont sensibles aux décharges statiques (ESD). Leur longévité pourrait être considérablement écourtée par le fait qu’aucune précaution n’est prise a leur manipulation. Lors de réparations, s’assurer de bien être relié au même potentiel que la masse de l’appareil et enfiler le bracelet serti d’une résistance de sécurité. Veiller a ce que les composa outils que l’on utilise soient également a ce potentiel.

NOTE HANDLING AND REPLACEMENT OF THE LASER PICK-UP

1. Protection of the LD

Short a part of the LD circuit by soldering. After connection to a circuit, remove the short solder.

2. Precautions when handling the laser CD mechanism

• Handle the laser pick-up so that it is not exposed to dust.

• Do not leave the laser pick-up bare. Be sure to cover it.

• If dust adheres on lens of the pick-up, blow it off with a blower brush.

• Do not shock the laser pick-up.

• Do not watch the light of the laser pick-up.

3. Cautions on assembling and adjustment

• Be sure that to the bench, jig, head of soldering iron (with ceramic) and measuring instruments are well grounded.

• Workers who handle the laser pick-up must be grounded.

• The nished mechanism (prior to anchoring in the set) should be protected against static electricity and dust. The

mechanism must be stored that damaging outside forces are not received.

• When carrying the nished mechanism, hold it by the chassis body

• For proper operation, storage and operating environment should not contain corrosive gases. For example H2S, SO2, NO2, CI2 etc. In addition storage environment should not have materials that emit corrosive gases especially from

silicic, cyanic, formalin and phenol group. I the mechanism or the set, existence of corrosive gases may cause no rotation in motor.

4. Determining whether the laser pick-up is defective

Disc no read, unsteady playback, etc.

Measure the waveform at RFO on "MCU CD PCB wRFO". (For measuring points and waveforms, Rrfer to 50 page.)

Range between 0.4 and 1.1(Vp-p)

Laser drive current (Iop) check

(For how to check, see 4. CD test mode, 4.7.Laser current is display.)
