Product Safety Notice; Power Source - Hitachi 27MMV30B Service Manual

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 an a 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.
Production 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.

CHASSIS GROUND
X-Radiation
TUBE: The primary source of X-Radiation in this receiver
is the picture tube. The tube utilized in this chassis is
specially constructed to limit X-Radiation emissions. For
continued X-Radiation protection, the replacement tube
must be the same type as the original HITACHI-approved
type.
When troubleshooting and making test measurements in
a receiver with an excessive high voltage problem, avoid
being unnecessarily close to the picture tube and the high
voltage component.
Do not operate the chassis longer than is necessary to
locate the cause of excessive voltage.
PRODUCT SAFETY NOTICE
This Service Manual is intended for qualified service
technicians; it is not meant for the casual do-it-yourselfer.
Qualified technicians have the necessary test equipment
