The above models are classified as green products (*1), as indicated by the underlined serial numbers. This Service Manual describes replacement parts for the green products. When repairing these green product(s), use the part(s) described in this manual and lead-free solder (*2).

For (*1) and (*2), see the next page.

Dec., 2006 GREEN

(*1) GREEN PRODUCT PROCUREMENT

The EC is actively promoting the WEEE & RoHS Directives that define standards for recycling and reuse of Waste Electrical and Electronic Equipment and for the Restriction of the use of certain Hazardous Substances. From July 1, 2006, the RoHS Directive will prohibit any marketing of new products containing the restricted substances.

Increasing attention is given to issues related to the global environmental. Toshiba Corporation recognizes environmental protection as a key management tasks, and is doing its utmost to enhance and improve the quality and scope of its environmental activities. In line with this, Toshiba proactively promotes Green Procurement, and seeks to purchase and use products, parts and materials that have low environmental impacts.

Green procurement of parts is not only confined to manufacture. The same green parts used in manufacture must also be used as replacement parts.

(*2) LEAD-FREE SOLDER

This product is manufactured using lead-free solder as a part of a movement within the consumer products industry at large to be environmentally responsible. Lead-free solder must be used in the servicing and repair of this product.

WARNING

This product is manufactured using lead free solder.

DO NOT USE LEAD BASED SOLDER TO REPAIR THIS PRODUCT !

The melting temperature of lead-free solder is higher than that of leaded solder by 86°F to 104°F (30°C to 40°C). Use of a soldering iron designed for lead-based solders to repair product made with lead-free solder may result in damage to the component and or PCB being soldered. Great care should be made to ensure high-quality soldering when servicing this product especially when soldering large components, through-hole pins, and on PCBs as the level of heat required to melt lead-free solder is high.

SERVICE SHOULD NOT BE ATTEMPTED BY ANYONE UNFAMILIAR WITH THE NECESSARY

SAFETY INSTRUCTIONS

WARNING: BEFORE SERVICING THIS CHASSIS, READ THE ＂SAFETY PRECAUTION＂

AND ＂PRODUCT SAFETY NOTICE＂INSTRUCTIONS BELOW.

SAFETY PRECAUTION

WARNING:

PRECAUTIONS ON THIS RECEIVER. THE FOLLOWING ARE THE NECE OBSERVED BEFORE SERVICING THIS CHASSIS.

・An isolation transformer should be connected in the power line between the receiver and the AC line before any service

is performed on the receiver.

・When replacing a chassis in the cabinet, always be certain that all the protective devices are put back in place, such as;

nonmetallic control knobs, insulating covers, shields, isolation resistor-capacitor network etc.

・Always advise users to keep children away. There is danger of injury to children from tools, disassembled products, etc.

・Always disconnect the power plug before starting work whenever power is not required. Failure to disconnect the power

plug before starting work can result in electrical shock.

・Depending on the model, use an insulation transformer or wear gloves when servicing with the power on, and disconnect

the power plug to avoid electrical shock when replacing parts. In some cases, alternating current is also impressed in the chassis, so electrical shock is possible if the chassis is contacted with the power on.

・Always use the replacement parts specified for the particular model when making repairs. The parts used in products have the necessary safety characteristics such as inflammability, voltage resistance, etc. ; therefore, use only

replacement parts that have these same characteristics. Use only the specified parts when the mark is include in a circuit diagram or parts list.

・Parts mounting and routing of the wiring should be the same as that used originally. For safety purposes, insulating materials

such as tubing or tape is sometimes used and printed circuit boards are sometimes mounted floating. Also make sure that wiring is routed and clamped to avoid parts that generate heat and which use high voltage. Always follow the original scheme.

・After a repair has been completed, reassemble all disassembled pars, and route and reconnect the wiring, in accordance with

the original scheme. Do not allow internal wiring to be pinched by cabinets, panels, etc. Any error in reassembly or wiring can result in electrical leakage, flame, etc.,and may be hazardous.

・Never remodel the product in any way. Remodeling can result in improper operation, malfunction, or electrical leakage and

flame, which may be hazardous.

Touch current check

(After completing the work, measure touch current to prevent an electric shock.)

・Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check..

・Connect a measuring network for touch currents between each exposed metallic part on the set and a good earth

ground such as a water pipe, as shown in Figure D.1

・The potential at any point(TOUCH CURRENT) expressed as voltage U

The part or contact of a TERMINAL is not HAZARDOUS LIVE if:

a) the open-circuit voltage does not exceed 35 V (peak) a.c or 60 V d.c.,

or,if a)is not met,

b) the measurement of the TOUCH-CURRENT shall be carried out in accordance with IEC 60990, with the measuring network

described in annex D of this standard.

The TOUCH CURRENT expressed as voltages U

NOTE-Appropriate measures should be taken to obtain the correct value in case of non-sinusoidal waveforms.

The measuring instrument is calibrated by comparing the frequency factor of U

with the solid line in figure F.2 of IEC 60990 at various frequencies. A calibration curve is constructed showing the deviation of U curve as a function of frequency.

PRODUCT SAFETY NOTICE

The use of substitute replacement parts which do not have the same safety characteristics as specified in the parts list

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics

are often passed unnoticed by a visual inspection and the protection afforded by them cannot necessarily be obtained by

using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this manual and its supplements; electrical components having such features are identified by the international hazard symbols on the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully.

may create shock, fire, or other hazards.

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 products 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 being turned on, you may not remove this laser cautions 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.

PART REPLACEMENT PROCEDURES

CAUTIONS BEFORE STARTING PART REPLACEMENT

Electronic parts are susceptible to static electricity and may 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.
