SERVICE MANUAL

Mar.,2006 GREEN

FILE No. 810-200627GR

SD-P1700SN

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 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 the 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.

(*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 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.

SAFTY NOTICE

Plug the AC line cord directly into the 120V AC outlet (do

not use an isolation transformer for this check). Use a

AC voltmeter, having 5000 per volt or more sensitivity.

Connect a 1500 10W resistor,paralleled by a 0.15uF

150V AC capacitor between a known good earth ground

(water pipe, conduit, etc.) and all exposed metal parts of

cabinet (antennas, handle bracket, metal cabinet

screwheads, metal overlays, control shafts, etc.).

SAFTY PRECAUTIONS

LEAKAGE CURRENT CHECK

Measure the AC voltage across the 1500 resistor.

The test must be conducted with the AC switch on and

then repeated with the AC switch off. The AC voltage

indicated by the meter may not exceed 0.3V.A reading

exceeding 0.3V indicates that a dangerous potential

exists, the fault must be corrected.

Repeat the above test with the DVD VIDEO PLAYER

power plug reversed.

NEVER RETURN A DVD VIDEO PLAYER TO THE

CUSTOMER WITHOUT TAKING THE NECESSARY

CORRECTIVE ACTION.

READING SHOULD NOT EXCEED 0.3V

The lightning flash with arrowhead symbol, within an

equilateral triangle, is intended to alert the user to the

presence of uninsulated "dangerous voltage" within the

product's enclosure that may be of sufficient magnitude to

constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is

intended to alert the user to the presence of important

operating and maintenance (servicing) instructions in the

literature accompanying the appliance.
