SERVICE MANUAL
MANUEL D'ENTRETIEN
WARTUNGSHANDBUCH
CAUTION:
Before servicing this chassis, it is important that the service technician read
the "Safety Precautions"and "Product Safety Notices"in this service manual.
ATTENTION:
Avant d'effectuer l'entretien du châassis, le technicien doit lire les
«Précautions de sécurité» et les «Notices de sécurité du produit» présentés
dans le présent manuel.
VORSICHT:
Vor Öffnen des Gehäuses hat der Service-Ingenieur die ,,Sicherheitshinweise"
und ,,Hinweise zur Produktsicherheit"in diesem Wartungshandbuch zu lesen.
Data contained within this Service
manual is subject to alteration for
improvement.

SAFETY PRECAUTIONS
WARNING: The following precautions should be ob-
served.
1. Do not install, remove, or handle the picture tube
in any manner unless shatter proof goggles are
worn. People not so equipped should be kept
away while picture tubes are handled. Keep the
picture tube away from the body while handling.
2. When service is required, an isolation transformer
should be inserted between the power line and
the receiver before any service is performed on
the chassis.
3. When replacing the chassis in the cabinet, ensure
all the protective devices are put back in place.
4. When service is required, observe the original
lead dressing. Extra precaution should be taken
to ensure correct lead dressing in the high volt-
age circuitry area.
5. Always use the manufacturer's replacement com-
ponent. Always replace original spacers and
maintain lead lengths. Especially critical compo-
nents are indicated thus I on the parts list and
should not be replaced by other makes. Further-
more, where a short circuit has occurred, replace
those components that indicate evidence of over-
heating.
6. Before returning a serviced receiver to the cus-
tomer, the service technician must thoroughly test
the unit to be certain that it is completely safe to
operate without danger of electrical shock, and
be sure that no protective device built into the in-
strument by the manufacturer has become defec-
tive, or inadvertently damaged during servicing.
Therefore, the following checks are recommended for
the continued protection of the customers and service
technicians.
INSULATION
Insulation resistance should not be less than lOM
ohms at 500V DC between the main poles and any
accessible metal parts.
Also, no flashover or breakdown should occur during
the dielectric strength test, applying 3kV AC or 4.25kV
DC for two seconds between the main poles and ac-
cessible metal parts.
HIGH VOLTAGE
High voltage should always be kept at the rated value
of the chassis and no higher. Operating at higher volt-
ages may cause a failure of the picture tube or high
voltage supply, and also, under certain circumstances
could produce X-radiation levels moderately in excess
of design levels. The high voltage must not, under any
circumstances, exceed 29kV on the chassis.
X-RADIATION
TUBES: The primary source of X-radiation in this re-
ceiver is the picture tube. The tube utilised for the
above mentioned function in this chassis is specially
constructed to limit X-radiation.
For continued X-radiation protection, replace tube with
the same type as the original HITACHI approved type.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in HITACHI tele-
vision receivers have special safety related character-
istics. These characteristics 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 by marking with a I on
the schematics and the replacement parts list con-
tained in this service manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
HITACHI recommended replacement one, shown in
the parts list of this service manual, may create elec-
trical 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 serv-
ice manual. A subscription to, or additional copies of
HITACHI service manuals may be obtained at a nomi-
nal charge from your HITACHI SALES CORPORA-
TION.
CE MARK
Some of these models may contain the CE mark on
the rating plate.
This illustrates that the T.V. contains parts that have
been specifically approved to provide electromagnetic
compatibility to designated levels.
Therefore, when replacing any part in this T.V., please
use only the correct part itemized in the parts list of
this service manual to ensure this standard is main-
tained.
Also, take care to replace lead dressing to its original
state, as this can also have a bearing on the electro-
magnetic radiation/immunity.
TUBE DISCHARGE
The line output stage can develop voltages in excess
of 25kV; if the E.H.T. cap is required to be removed,
discharge the anode to chassis via a high value re-
sistor, prior to its removal from the tube.
