(MFR’S VERSION A)

The above model is classified as a green product (*1), as indicated by the underlined serial number.

This Service Manual describes replacement parts for the green product. When repairing this green

product, use the part(s) described in this manual and lead-free solder (*2).

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

A1-1

(*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 lead.

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 CE

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.

SERVICING NOTICES ON CHECKING

1. KEEP THE NOTICES

As for the places which need special attentions,

they are indicated with the labels or seals on the

cabinet, chassis and parts. Make sure to keep the

indications and notices in the operation manual.

3. USE THE DESIGNATED PARTS

2. AVOID AN ELECTRIC SHOCK

There is a high voltage part inside. Avoid an

electric shock while the electric current is

flowing.

The parts in this equipment have the specific

characters of incombustibility and withstand

voltage for safety. Therefore, the part which is

replaced should be used the part which has

the same character.

Especially as to the important parts for safety

which is indicated in the circuit diagram or the

table of parts as a mark, the designated

parts must be used.

5. PUT PARTS AND WIRES IN THE

ORIGINAL POSITION AFTER

ASSEMBLING OR WIRING

There are parts which use the insulation

material such as a tube or tape for safety, or

which are assembled in the condition that

these do not contact with the printed board.

The inside wiring is designed not to get closer

to the pyrogenic parts and high voltage parts.

Therefore, put these parts in the original

positions.

PERFORM A SAFETY CHECK AFTER

SERVICING

Confirm that the screws, parts and wiring which

were removed in order to service are put in the

original positions, or whether there are the

portions which are deteriorated around the

serviced places serviced or not. Check the

insulation between the antenna terminal or

external metal and the AC cord plug blades.

And be sure the safety of that.

(INSULATION CHECK PROCEDURE)

Unplug the plug from the AC outlet.

Remove the antenna terminal on TV and turn

on the TV.

Insulation resistance between the cord plug

terminals and the eternal exposure metal

[Note 2] should be more than 1M ohm by

using the 500V insulation resistance meter

[Note 1].

If the insulation resistance is less than 1M

ohm, the inspection repair should be

required.

[Note 1]

If you have not the 500V insulation

resistance meter, use a Tester.

[Note 2]

External exposure metal: Antenna terminal

Earphone jack

4. BE CAREFUL WITH THE

LCD PANEL

Avoid a shock to the panel while servicing.

Take enough care to deal with it.

When you exchange IC and Transistor with a heat sink, apply silicon grease on the contact section of

the heat sink. Befor applying new silicon grease, remove all the old silicon grease.

(Old grease may cause damages to the IC and Transistor.)
