SAFETY PRECAUTIONS

The following items should be checked for continued protection of the customer and the service technician.
leakage current check
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. Be sure to test for leakage current with the AC plug in both polarities, in addition, when the set's power is in each state (on, off and standby mode), if applicable.
CAUTION
Please heed the following cautions and instructions during servicing and
inspection.
◎Heed the cautions!
Cautions which are delicate in particular for servicing are labeled on the cabinets, the parts and the chassis, etc. Be sure to heed these cautions and the cautions described in the handling instructions.
◎Cautions concerning electric shock!
(1) An AC voltage is impressed on this set, so if you
touch internal metal parts when the set is energized, you may get an electric shock. Avoid getting an electric shock, by using an isolating transformer and wearing gloves when servicing while the set is energized, or by unplugging the power cord when replacing parts, for example.
(2) There 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 parts were manufactured from sheet metal, there may be burrs on
the edges of parts. The burrs could cause injury if ngers
are moved across them in some rare cases. Wear gloves to protect your hands.
◎Use only designated parts!
The set's parts have specic safety properties (re
resistance, voltage resistance, etc.). Be sure to use parts which have the same properties for replacement. The burrs have the same properties. In particular, for the important safety parts that are indicated by the z mark on schematic diagrams and parts lists, be sure to use the designated parts.
◎ Be sure to mount parts and arrange the wires
as they were originally placed!
For safety seasons, some parts use tapes, 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 wires by arranging them and using clamps to keep them away from heating and high voltage parts, so be sure to set everything back as it was originally placed.
◎Make a safety check after servicing!
Check that all screws, parts and wires removed or disconnected when servicing have been put back in their original positions, check that no serviced parts have deteriorate the area around. Then make 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 on the power. Using a 500V insulation resistance tester, check that the insulation resistance value between 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 the structural parts used in the set have special safety properties. In most cases these
properties are difcult to distinguish by sight, and the use
of replacement parts with higher ratings (rated power and withstand voltage) does not necessarily guarantee that safety performance will be preserved. Parts with safety properties are indicated as shown below on the wiring diagrams and the parts list in this service manual. Be sure to replace them with the parts which have the designated part number.
(1) Schematic diagrams .......Indicated by the z mark.
(2) Parts lists .......Indicated by the z mark.
The use of parts other than the designated parts could cause electric
shocks, res or other dangerous
situations.

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.
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 composants ainsi que les outils que l’on utilise soient également a ce potentiel.
Alle IC und viele andere Halbleiter sind empfindlich gegen elektrostatische Entladungen (ESD). Unsorgfältige Behandlung bei der Reparatur kann die Lebensdauer drastisch vermindern. Sorgen sie dafür, das Sie im Reparaturfall dem Massepotential des Gerätes verbunden sind. Halten Sie Bauteile und Hilfsmittel ebenfalls über ein Pulsarmband mit Widerstand mit auf diesem Potential.
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 apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevita potrebbe essere fortemente ridatta in caso di non osservazione della piu grande cauzione alla loro manipolazione. Durante le riparazioni occorre quindi essere collegato allo stesso potenziale che quello della massa dell’apparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

Measurement of Board Test Points for Servicing

When measuring the board test points during servicing, the measurements can be performed easily by turning over the
MAIN board with the back panel still attached by screws, as shown in the gure below.
Disassembly Procedure (See "DISASSEMBLY" for details on the disassembly procedure)
1. Remove all of the screws from the MAIN PWB, SMPS PWB, CD Mecha, CD Foot, NET PWB, USB PWB and chassis (CD Mecha and CD Foot are for the M-CR610 only).
2. Remove the SMPS PWB, CD Mecha and CD Foot (CD Mecha and CD Foot are for the M-CR610 only).
3. Remove the wire and FFC connected to the FRONT PWB.
4. Remove the molded parts from the back panel.
5. Raise the MAIN board, slide the entire back panel to the rear, and remove everything from the back panel to PWB as a set.
11
Removing the AMP PWB from the MAIN PWB
Pay close attention to the following two points when removing/attaching the AMP PWB to the MAIN PWB during servicing.
1. Wait for approximately 5 minutes after turning the power off before removing the wire connector that connects the SMPS PWB and AMP PWB. When connected to the SMPS PWB wire connector, a surge current may occur due to the charge stored in the AMP PWB causing damage to the D-AMP IC41 and IC42 (IC41 only for the M-CR510).
2. When attaching the AMP PWB to the MAIN PWB connector, insert the connector pins into the AMP PWB beforehand, and securely connect while checking that the position is correct. If the MAIN PWB and AMP PWB terminals are connected incorrectly (if the connection pins are misaligned), the PWM Processor IC56, D-AMP IC41 and IC42 (IC41 only for the M-CR510) may be damaged by the charge stored in the condenser.

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

Check the Iop(Laser drive current). Check lop in "SPECIAL MODE". (Refer to 21 page.)
If the present Iop (current) value becomes more than 50mA, replace the Traverse unit with a new one.
No mechanical adjustment is necessary after the replacement.
Protective soldering place for laser diode.
