TECHNICAL CAUTIONS
SAFETY PRECAUTIONS
WARNING: Since the chassis of this receiver is connected
to one side of the Mains Supply during operation, service
should not be attempted by anyone unfamiliar with the
precautions necessary when working on this type of equipment.
The folfowing precautions should be observed.
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 picture tube away from the body while handing.
. When replacing chassis in the cabinet, all the protective
devices are put back in place, such as; barriers, non-
metallic knobs, adjustment and compartment cover or shields,
isolation resistors-capacitors, etc..
3. When service is required, observe the original lead dress, Extra
care should be taken to assure correct lead dress in the high
voltage circuitry area.
. Always use the manufacturer's replacement component.
Especially critical components as indicated on the circuit
diagram should not be replaced by other makes.
Furthermore where.a short circuit has occurred, replace
those components that indicate evidence of overheating.
5, Before returning a serviced receiver to the customer, the
service technician must thoroughtly 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 instrument by the manufacturer has became
defective, or inadvertenly defeated during servicing.
Therefore, the following checks are recommended for the
continued protection of the customers and service
technicians,
INSULATION
Insulation resistance between the mains poles and any
accessible metal parts should not be less than 7MQ at 500V
DC. Also, no flashover or breakdown should occur during the
dielectric strength test, to apply 4KV AC for one minute
between the mains poles and any accessible metal parts.
bo
>
X-RADIATION
TUBES: Tie 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,
For continued X radiation protection, the replacement tube must
be the same type as the original, HITACHI approved type.
High Voltage
This receiver is provided with a hold down circuit for
clearly indicating that voltage has increased in excess of
a predetermined value, Comply with al! notes described in
this Service Manual regarding this hold down circuit when
servicing, so that this hold down circuit is operated
correctly.
Serviceman Warning
With minimum Black Level and Picture, the operating high
voltage in this receiver is lower than 31.0K. In case any
component having influence on the high voltage is replaced,
confirm that high voltage with minimum Brightness and contrast
is lower than 33.0kV. To measure H. V. use a high impedance H. V.,
meter. Connect (-) to chassis earth and (+) to the CRT anode .
button. (See the following connection diagram).
NOTE: Turn the power switch off without fail before the
connection to the Anode button is made,

PRODUCT SAFETY NOTICE
Many electrical and mechanica! parts in HITACHI television
receiver have special safety related characteristics. These
characteristics are often not evident from visual inspection
nor can be protection afforded by them necessarily be obtained
by using replacement components rated for higher vol tage,
wattage, etc. Replacement parts which have these specia! safety
characteristics are identified in this Service Manual.
Electrical components having such features are identified by
marking with a A mark in the schematics and on the
replacement 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
one shown in the parts list in this Service Manual, may create
electrical shock, fire, X radiation, or other hazards.
Product Safety is continuously under review and new
instrictions are issued from time to time. For the latest
information, al’ ays consult the current HITACHT Service Manual.
A subscription to, or additional copies of, HITACHI Service
Manual may be obtained at a nomina! charge from your HITACHI
sales offices, .

TECHNICAL CAUTIONS
High voltage limiter circuit operation check
1, Connect the high voltage voltmeter between the CPT anode
(anode cap) and GND (CPT grounding Jead).
2, Receive the broadcast signal and set the brightness and
contrast VRs to max. Set the beam current to 1.5mA+10%..
(After cut-off adjustment)
3, Set the AC input voltage to 220-43V,
4, Check that the constant high voltage is 28,0 +1.0kV at this time.
5, Turn the switch of the set to off and connect the jig shown
in Fig.3 at both ends of R956 as shown in Fig. 1.
6. With the brightness and contrast VRs left as set in item 2
and with the AC input voltage stabilized at 220V, turn the
picture disappears with a high voltage of 32.5kV or less.
7. Turn the switch of the set to off immediately after the
check is completed.
8. Remove the adjust jigs and high voltage voltmeter,
NOTE : When connecting disconnecting the high voltage volt-
meter to from the anode cap, be sure to turn the
switch of the set off and do it after the residual
high voltage is discharged to the chassis because the
high voltage may remain at the anode cap.
