(MFR’S VERSION A)FILE NO. 050-200609GR
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 ofcertain 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 toenhance 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 inmanufacture must also be used as replacement parts.
(*2) LEAD-FREE SOLDERThis product is manufactured using lead-free solder as a part of a movement within the consumerproducts industry at large to be environmentally responsible. Lead-free solder must be used inthe servicing and repair of this product.
WARNINGThis 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 madewith lead-free solder may result in damage to the component and or PCB being soldered. Greatcare 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 heatrequired 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 thecabinet, 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 highvoltage peripheral circuit, etc.Therefore, when repairing the high voltage pe-ripheral circuit, use the designated parts andmake sure not modify the circuit.Repairing except indicates causes rising of highvoltage, 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 DESCRIPTION
You 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 maycause damages to the IC and Transistor.)
IMPORTANT
2. AVOID AN ELECTRIC SHOCKThere is a high voltage part inside. Avoid anelectric shock while the electric current isflowing.
The parts in this equipment have the specificcharacters of incombustibility and withstandvoltage for safety. Therefore, the part which isreplaced should be used the part which hasthe same character.Especially as to the important parts for safetywhich is indicated in the circuit diagram or thetable of parts as a mark, the designatedparts must be used.
4. PUT PARTS AND WIRES IN THEORIGINAL POSITION AFTERASSEMBLING OR WIRINGThere are parts which use the insulationmaterial such as a tube or tape for safety, orwhich are assembled in the condition thatthese do not contact with the printed board.The inside wiring is designed not to get closerto the pyrogenic parts and high voltage parts.Therefore, put these parts in the originalpositions.
In the condition that an explosion-proof cathode-ray tube is set in this equipment, safety issecured against implosion. However, whenremoving it or serving from backward, it isdangerous to give a shock. Take enough care todeal with it.
PERFORM A SAFETY CHECK AFTERSERVICING
7.
Confirm that the screws, parts and wiring whichwere removed in order to service are put in theoriginal positions, or whether there are theportions which are deteriorated around theserviced places serviced or not. Check theinsulation between the antenna terminal orexternal 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 turnon the TV.Insulation resistance between the cord plugterminals 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 1Mohm, the inspection repair should berequired.
[Note 1]
If you have not the 500V insulationresistance meter, use a Tester.
