PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in HITACHI television
receivers have special safety-related characteristics. These are
often not evident from visual inspection nor can the protection
afforded by them necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement
parts which have these special safety characteristics are
identified in this Service Manual.
Electrical components having such features are identified with a
1 mark in the schematics and parts list in this Service Manual.
The use of a substitute replacement component which does not
have the same safety characteristics as the HITACHI-
recommended replacement component, shown in the parts list in
this Service Manual, may create shock, fire, X-radiation, or other
hazards.
Product safety is continuously under review and new instructions
are issued from time to time. For the latest information, always
consult the current HITACHI Service Manual. A subscription to,
or additional copies of HITACHI Service Manuals may be
obtained at a nominal charge from HITACHI Sales Corporation.

1. Follow the general caution recommendations from “Safety
precautions” section.
2. If necessary to replace Panel module, this work must be
started after the panel module and the AC/DC Power supply
becomes sufficiently cool.
3. Special care must be taken with the display area to avoid
damaging its surface.
4. The Panel Module shall not be touched with bare hands to
protect its surface from stains.
5. It is recommended to use clean soft gloves during the
replacing work of the Panel module in order to protect, not
only the display area of the panel module but also the
serviceman.
6. Signal, power supply P.W.B.’s and LCD driving circuits
P.W.B.’s are assembled on the rear side of the LCD module,
take special care with this fragile circuitry; particularly, Flexible
Printed Circuits bonded to surrounding edges of the panel.
They are not strong enough to withstand harsh outer
mechanical forces. Avoid touching the flexible printed circuits
by not only your hands, but also tools, chassis, or any other
object. Extreme bending of the connectors must be avoided
too. In case the flexible printed circuits are damaged, the
corresponding addressed portions of the screen will not be lit
and exchange of the panel will be required.
WARNING
Lead in solder used in this product is listed by the California
Health and Welfare agency as a known reproductive toxicant
which may cause birth defects or other reproductive harm
(California Health and Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components
which contain lead in solder, avoid unprotected skin contact with
solder. Also, when soldering make sure you are in a well
ventilated area in order to avoid inhalation of any smoke or
fumes released.
