The above models are classified as green products (*1), as indicated by the underlined serial numbers.
This Service Manual describes replacement parts for the green products. When repairing these green
product(s), 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.
PREPARATION OF SERVICING
Pickup Head consists of a laser diode that is very susceptible to external static electricity.
Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement, its
life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire, etc. to protect the
laser diode from damage by static electricity.
And also, the LSI and IC are same as above.

LEAKAGE CURRENT CHECK
Plug the AC line cord directly into a 120V AC outlet (do
not use an isolation transformer for this check). Use an
AC voltmeter, having 5000 Ωper volt or more sensitivity.
Connect a 1500 Ω10 W resistor, paralleled by a 0.15 µF
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.).
Measure the AC voltage across the 1500 Ωresistor.
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 0.3 V. A reading
exceeding 0.3 V indicates that a dangerous potential
exists, the fault must be located and corrected.
Repeat the above test with the DVD VIDEO RECORDER
power plug reversed.
NEVER RETURN A DVD VIDEO RECORDER TO
THE CUSTOMER WITHOUT TAKING 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.

CAUTIONS BEFORE STARTING PART REPLACEMENT
Electronic parts are susceptible to static electricity and may easily damaged, so do not forget to ground as required.
Many screws are used inside the unit. To prevent the screws from missing or dropping, etc. always use a magnetized
screwdriver in servicing. Several kinds of screws are used and some of them need special cautions. That is, take care of
the tapping screws securing molded parts and fine pitch screws used to secure metal parts. If they are used improperly,
the screw holes will be easily damaged and the parts can not be fixed.
