(MFR’S VERSION A)FILE NO. 050-200611GR
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
1. KEEP THE NOTICESAs 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
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.
5. 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.
PERFORM A SAFETY CHECK AFTERSERVICING
6.
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.

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 2.5M ohm byusing the 500V insulation resistance meter[Note 1].If the insulation resistance is less than 2.5Mohm, the inspection repair should berequired.
[Note 1]
If you have not the 500V insulationresistance meter, use a Tester.

4. BE CAREFUL WITH THE PDP PANEL
When you handle the PDP Filter you mustwear the gloves twice, because, you are toavoid soil it by your sweat and dust.When you lift the PDP Filter you should hold itwith the palm of your hand.Don’t pick up it with your fingers.The back side of PDP Filter tends to damaged.Since there is no coating.Therefore, it put into the packing box at thetime of delivery, without piling up even at thetime of unused.Also, when you take out it from a packing box,be careful of the rubbing.When the surface becomes dirty, wipe it with asoft cloth as you draw a circle.When it is dirty hardly, wipe it with a clothethanol infiltrated.Don’t use ethanol for the back side.Do not apply it to direct sunshine so that thecharacteristic may change.When you inspect the surface (the scratch, thedirt and the air bubble), use the fluorescentlight.When you use SCREW DRIVER and SCREW,be careful of a metallic powder being mixed.Do not damage the PDP Module with aDRIVER.Do Handling with the PDP Module by 2persons.There is a step difference between the coverand PDP Module.So, when you remove the screws, place acushion on it so that the PDP Module is notbeing scratched.Then remove the screws carefully.

When you remove the cover, do not scratch theFPC on both ends of PDP Module.Hold the four ends holder and be careful not totouch the glass area.Take care for the damage of vacuum exhaustpipe due to a collision.Moisture condensation may damage the PDPModule.So, leave it for 48 hours at the service room.

HOW TO ORDER PARTS
When you exchange IC and Transistor with a heat sink, apply silicon grease (YG6260M) on the contactsection of the heat sink. Before applying new silicon grease, remove all the old silicon grease.(Old grease may cause damage to the IC and Transistor).

When you handle the PDP Filter, you must wear gloves to avoid soiling it with sweat and dust.When you lift the PDP Filter, use the palm of your hand. Don’t pick it up with your fingers.The back side of the PDP Filter tends to get damaged, since there is no coating. Therefore, it needs to be put into thepacking box at the time of delivery, even if it is not being used at the time. Also, when you take it out of the packing box, becareful not to rub the appearance.When the surface becomes dirty, use a cloth which is soft and dust free and wipe it in a circular motion.When very dirty, lightly use alcohol on the cloth to wipe. Do not use alcohol for the back side.Do not apply it to direct sunlight, the characteristics may change.When you inspect for scratches and dirt, use a light to check for air bubbles on the PDP Filter surface.
