(MFRS VERSION B)

FILE NO. 050-200607GR

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.

(*1) GREEN PRODUCT PROCUREMENTThe EC is actively promoting the WEEE & RoHS Directives that define standards for recyclingand 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 anymarketing of new products containing the restricted substances.

Increasing attention is given to issues related to the global environmental. Toshiba Corporationrecognizes 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 inthe 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 86F to 104F(30C to 40C). Use of a soldering iron designed for lead-based solders to repair product madewith 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 especiallywhen 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

6. AVOID AN X-RAY1. 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 theindications and notices in the operation manual.

3. USE THE DESIGNATED PARTS

5. TAKE CARE TO DEAL WITH THECATHODE-RAY TUBE

Safety is secured against an X-ray by consider-ing about the cathode-ray tube and the high

voltage peripheral circuit, etc.Therefore, when repairing the high voltage pe-

ripheral circuit, use the designated parts and

make sure not modify the circuit.Repairing except indicates causes rising of high

voltage, and it emits an X-ray from the cathode-ray tube.

Please include the following informations when you order parts. (Particularly the VERSION LETTER.)

1. MODEL NUMBER and VERSION LETTER

The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be found at the end of the SERIAL NUMBER.

2. PART NO. and DESCRIPTIONYou can find it in your SERVICE MANUAL.

HOW TO ORDER PARTS

When you exchange IC and Transistor with a heat sink, apply silicon grease on the contact section ofthe heat sink. Befor applying new silicon grease, remove all the old silicon grease. (Old grease may

cause damages to the IC and Transistor.)

IMPORTANT

2. AVOID AN ELECTRIC SHOCKThere is a high voltage part inside. Avoid an

electric shock while the electric current isflowing.

The parts in this equipment have the specificcharacters of incombustibility and withstand

voltage for safety. Therefore, the part which isreplaced 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 designatedparts must be used.

4. PUT PARTS AND WIRES IN THEORIGINAL POSITION AFTER

ASSEMBLING OR WIRING

There are parts which use the insulationmaterial 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.

In the condition that an explosion-proof cathode-ray tube is set in this equipment, safety is

secured against implosion. However, when

removing it or serving from backward, it isdangerous to give a shock. Take enough care to

deal with it.

PERFORM A SAFETY CHECK AFTERSERVICING

7.

Confirm that the screws, parts and wiring which

were removed in order to service are put in the

original positions, or whether there are theportions which are deteriorated around the

serviced places serviced or not. Check theinsulation between the antenna terminal or

external metal and the AC cord plug blades.

And be sure the safety of that.(INSULATION CHECK PROCEDURE)

1.2.

3.

4.

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 byusing 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

1. REMOVAL OF ANODE CAP

Read the following NOTEDitems before starting work.

After turning the power off there might still be a potential

voltage that is very dangerous. When removing the

Anode Cap, make sure to discharge the Anode Cap'spotential voltage.

Do not use pliers to loosen or tighten the Anode Cap

terminal, this may cause the spring to be damaged.

*

*

REMOVAL

1. Follow the steps as follows to discharge the Anode Cap.

(Refer to Fig. 1-1.)

Connect one end of an Alligator Clip to the metal part of a

flat-blade screwdriver and the other end to ground.

While holding the plastic part of the insulated Screwdriver,

touch the support of the Anode with the tip of the

Screwdriver.

A cracking noise will be heard as the voltage is discharged.

Flip up the sides of the Rubber Cap in the direction of the

arrow and remove one side of the support.(Refer to Fig. 1-2.)

NOTE

REMOVAL AND INSTALLATION OFFLAT PACKAGE IC

Some ICs on the PCB are affixed with glue, so becareful not to break or damage the foil of each IC lead

or solder lands under the IC when removing it.

NOTE

Masking is carried out on all the parts located within 10

mm distance from IC leads.

Blower type ICdesoldering machine

IC

Heat the IC leads using a blower type IC desoldering

machine. (Refer to Fig. 2-2.)

2.

Fig. 2-2

NOTE

Do not rotate or move the IC back and forth , until ICcan move back and forth easily after desoldering the

leads completely.

When IC starts moving back and forth easily after

desoldering completely, pickup the corner of the IC using

tweezers and remove the IC by moving with the IC

desoldering machine. (Refer to Fig. 2-3.)

NOTE

When the IC leads are bent during soldering and/orrepairing, do not repair the bending of leads. If the

bending of leads are repaired, the pattern may bedamaged. So, always be sure to replace the IC in this

case.

Finally, confirm the soldering status on four sides of the I

using a magnifying glass.

Confirm that no abnormality is found on the soldering

position and installation position of the parts around the IIf some abnormality is found, correct by resoldering.

5.Solder temporarily

INSTALLATION

Take care of the polarity of new IC and then install the new

IC fitting on the printed circuit pattern. Then solder each

lead on the diagonal positions of IC temporarily.

1. ADJUSTMENT PROCEDURE

Read and perform these adjustments when repairing thecircuits or replacing electrical parts or PCB assemblies.

CAUTION

Use an isolation transformer when performing any

service on this chassis.Before removing the anode cap, discharge electricity

because it contains high voltage.When removing a PCB or related component, after

unfastening or changing a wire, be sure to put the wireback in its original position.

When you exchange IC and Transistor with a heat sink,

apply silicon grease on the contact section of the heatsink. Befor applying new silicon grease, remove all the

old silicon grease. (Old grease may cause damages tothe IC and Transistor.)

Prepare the following measurement tools for electrical

adjustments.
