GREEN PRODUCT PROCUREMENT

(*1)

The EC is actively promoting the WEEE & RoHS Directives that define standards for recycling
and reuse of Waste Electrical and Electronic Equi pment 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 th e 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.

LEAD-FREE SOLDER

(*2)

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 b y 86°F to 104°F
(30°C to 40°C). Use of a soldering iron designed for lead-based solders to repair produ ct 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.

1. Safety Notices and Precautions

Prior to using this service guide, ensure that you have carefully followed all the procedures outlined in the
15SLDT3R/19SLDT3R/22SLDT3R/26SLDT3R LCD TV user manual. Make sure to note and follow all
warnings and instructions marked on the product. Save these instructions for future reference.

 The LCD TV should be installed on a solid horizontal base.
 Do not use the LCD TV near water.
 Avoid exposing the LCD TV to moisture or high humidity.
 Do not install near any heat sources such as radiators, heat registers, stoves or any other

equipment (including amplifiers) that produce heat.

 Avoid exposing the LCD TV to direct sunlight or high temperatures. Hot air may cause damage to

the cabinet and other parts.

 Slots and openings in cabinet and the back or bottom are provided for ventilation. Adequate

ventilation must be maintained to ensure reliable and continued operation and to protect the
display from overheating. Observe the following.
 Do not block ventilation slots and openings with objects or install the display in a place

where ventilation may be hindered.

 The ventilation slots should never be blocked by placing the product on a bed, sofa, rug, or

other similar surface.

 This product should not be placed in built-installation unless proper ventilation is provided.

 Do not install this display near a motor or transformer where strong magnetism is generated.

Images on the display will become distorted and the color irregular.

 When cleaning, use only a neutral detergent cleaner with a soft damp cloth. Do not spray with

liquid aerosol cleaners.

 Refer all servicing to qualified service personnel. Do not attempt repairs yourself. Your warranty

does not cover repairs or attempted repairs by anyone not authorized by the manufacturer.

CAUTION

THIS LCD COLOR TELEVISION EMPLOYS A LASER SYSTEM.
TO ENSURE PROPER USE OF THIS PRODUCT, PLEASE READ THIS SERVICE MANUAL

CAREFULLY A ND RETAIN FOR FUTURE REFERENCE. SHOULD THE UNIT REQUIRE
MAINTENANCE, CONTACT AN AUTHORIZED SERVICE LOCATION-SEE SERVICE
PROCEDURE.

USE OF CONTROLS, ADJUSTMENTS OR THE PERFORMANCE OF PROCEDURES OTHER
THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

TO PREVENT DIRECT EXPOSURE TO LASER BEAM, DO NOT TRY TO OPEN THE
ENCLOSURE.

VISIBLE LASER RADIATION MAY BE PRESENT WHEN THE ENCLOSURE IS OPENED. DO NOT
STARE INTO BEAM.

Preparation of Servicing

The laser diode used for a pickup head may be destroyed with external static electricity.
Moreover, even if it is operating normally after repair, when static electricity discharge is received at

the time of repair, the life of the product may be shortened.
Please perform the following measure against static electricity, be careful of destruction of a laser

diode at the time of repair.

 Place the unit on a workstation equipped to protect against static electricity, such as

conductive mat.

 Soldering iron with ground wire or ceramic type is used.
 A worker needs to use a ground conductive wrist strap for body.

Servicing Environment

1. This LCD TV should be used only with the power source type identified on the package and on
the user’s guide.

2. Service the LCD TV in a room with low humidity and free of dust.

3. Place the LCD TV on a stable, level surface. Subjecting the LCD TV to a drop or sharp impact
may cause severe damage to thin glass, plastic surface materials, and internal components.

4. If necessary, clean the LCD TV with a slightly damp cloth using clean water. Disconnect the LCD
TV from the power source before cleaning. Do not use ammonia-based cleaning products.

5. In the event that the powered LCD TV rapidly heats, or emits unusual smells or noises,
immediately disconnect the unit from the power source.

6. To avoid electrical hazard, make sure that the LCD TV is fully assembled—the casing closed and
all the screws tightened completely—before plugging it in for testing.

7. The LCD TV’s internal components may be damaged by electrostatic discharge (ESD). Carry out
repairs in an ESD-protected workshop. If no such workshop is available, wear an antistatic wrist
strap or touch a highly conductive metal object.

8. Before opening the housing, disconnect the LCD TV from all power sources and remove all
peripheral cables. If the LCD TV has not been disconnected from the power outlet before being
opened, there is a danger to life through electric shock. There is also a risk of damage to the
components.
