SAFETY PRECAUTIONS
1. Before returning an instrument to the customer,
always make a safety check of the entire instrument,
including but not limited to the following items:
a) Be sure that no built-in protective devices are
defective and/or have been deleted during servicing.
(1) Protective shields are provided on this chassis to
protect both the technician and the customer.
Correctly replace all missing protective shields,
including any removal for servicing convenience.
(2) When reinstalling the chassis and/or other
assembly in the cabinet, be sure to put back in place
all protective devices, including but not limited to
nonmetallic control knobs, insulating fish-paper,
adjustment and compartment covers shields, and
isolation resistor/capacitor networks. Do not operate
this instrument or permit it to be operated
without all protective devices correctly installed
and functioning. Service technician who
disregard safety features or fail to perform safety
checks may be liable for any resulting damage.
b) Be sure that there are no cabinet openings through
which an adult or child might be able to insert their
fingers and contact a hazardous voltage. Such
openings include, but are not limited to
(1) spacing between the picture tube and cabinet
mask,
(2) excessively wide cabinet ventilation slots, and
(3) an improperly fitted and/or incorrectly secured
cabinet back cover.
c) Antenna Cold Check - With the instrument AC plug
source, connect an electrical jumper across the two
AC plug prongs. Place the instrument AC switch in
the ON position. Connect one lead of an ammeter to
the AC plug prongs tied together and touch the other
ohmmeter lead to each tuner antenna input,
exposed terminal screw and, if applicable, to the
coaxial connector in sequence. If the measured
resistance is less than 4.0 megohm or greater than
10 megohm, an abnormality exists that must be
corrected before the instrument is returned to the
customer. Repeat this test with the instrument AC
switch in the OFF position.
d) Leakage Current Hot Check - With the instrument
completely reassembled, plug the AC line cord
directly into a 220V outlet. (Do not use an isolation
transformer during this test.) Use a leakage current
tester or a metering system with the instrument AC
switch first in the ON position and then in the OFF
position, measure from a known earth ground (metal
water-pipe, conduit, etc.), to all exposed metal parts
of the instrument (antennas, handle bracket, metal
cabinet, screw heads, metallic overlays, control
shafts, etc.), especially any exposed metal parts that
offer an electrical return path to the chassis. Any
current measured must not exceed 0.7 milliamps.
Reverse the instrument power cord plug in the outlet
and repeat test. (See the following connection
diagram)
AC Leakage Test
ANY MEASUREMENTS NOT WITHIN THE LIMITS
SPECIFIED HEREIN INDICATE A POTENTIAL
SHOCK HAZARD THAT MUST BE ELIMINATED
BEFORE RETURNING THE INSTRUMENT TO THE
CUSTOMER OR BEFORE CONNECTING THE
ANTENNA OR ACCESSORIES
e) High Voltage - This receiver is provided with a hold
down clearly indicating that voltage has increased in
excess of a predetermined value. Comply with all
notes described in this Service Manual regarding
this hold down circuit when servicing, so that this
hold down circuit may correctly be operated.
f) Service Warning - With maximum contrast,
operating high voltage in this receiver is lower than
30.9kV(4:3 Model) or 31.9kV(16:9 Model). In case if
any component having influence on high voltage is
replaced, confirm that the high voltage with
maximum contrast is lower than 30.9kV(4:3 Model)
or 31.9kV(16:9 Model). 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: Must turn power switch off before the connection
to the anode button is made.

SAFETY PRECAUTIONS
Fig. 1 X-ray shield plates
g) X-radiation (TUBE) -The primary source of
X-radiation in this receiver is the picture tube. The tube
utilized for the above mentioned function 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 a problem of excessive high voltage,
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.
h) X-radiation Shield -This receiver is provided with
X-ray shield plates for protection against X-radiation.
Do not remove X-ray shield plates A, B, C, or D
shown in Fig.1 unnecessarily, when troubleshooting
and/or making test measurements.
To prevent X-radiation, after replacement of picture
tube and lens, confirm these components to be fixed
correctly to bracket and cabinet, and not to be taken
off easily.

SAFETY PRECAUTIONS
2. Read and comply with all caution and safety-related
notes on or inside the receiver cabinet, on the
receiver chassis, or on the picture tube.
3. Design Alteration Warning - Do not alter or add to
the mechanical or electrical design of this TV receiver.
Design alterations and additions, including but not
limited to circuit modifications and the addition of
items such as auxiliary audio and/or video output
connectors, might alter the safety characteristics of
this receiver and create a hazard to the user. Any
design alterations or additions may void the
manufacturer’s warranty and may make you, the
servicer, responsible for personal injury or property
damage resulting therefrom.
4. Picture Tube Implosion Protection Warning - The
picture tube in this receiver employs integral
implosion protection. For continued implosion
protection, replace the picture tube only with one of
the same type number. Do not remove, install, or
otherwise handle the picture tube in any manner
without first putting on shatterproof goggles equipped
with side shields. People not so equipped must be
kept safely away while picture tubes are handled.
Keep the picture tube away from your body. Do not
handle the picture tube by its neck.
5. Hot Chassis Warning
a) Some TV receiver chassis are electrically connected
directly to one conductor of the AC power cord and
may be safely serviced without an isolation
transformer only if the AC power plug is inserted so
that the chassis is connected to the ground side of the
AC power source. Confirm that the AC power plug is
inserted correctly with an AC voltmeter by measuring
between the chassis and a known earth ground. If a
voltage reading in excess of 1.0V is obtained, remove
and reinsert the AC power plug in the opposite polarity
and again measure the voltage potential between the
chassis and a known earth ground.
b) Some TV receiver chassis normally have 85V AC
(RMS) between chassis and earth ground regardless
of the AC plug polarity. These chassis can be safely
serviced only with an isolation transformer inserted in
the power line between the receiver and the AC power
source, for both personnel and test equipment
protection.
c) Some TV receiver chassis have a secondary ground
system in addition to the main chassis ground. This
secondary ground system is not isolated from the AC
power line. The two ground systems are electrically
separated by insulating material that must not be
defeated or altered.
6. Observe original lead dress. Take extra care to assure
correct lead dress (the AC supply, high voltage and
antenna wiring) in the following areas:
a) Near sharp edges
b) Near thermally hot parts
Be sure that leads and components do not touch
thermally hot parts. Always inspect in all areas for
pinched, out-of -plate, or frayed wiring; Do not
change spacing between components and the printed
circuit board; Check AC power cord for damage.
7. Components, parts, and/or wiring that appear to have
overheated or are otherwise damaged should be
replaced with components, parts or wiring that meet
original specifications. Additionally, determine the
cause of overheating and/or damage and, if
necessary, take corrective action to remove any
potential safety hazard.
8. PRODUCT SAFETY NOTICE - Many TV electrical
and mechanical parts have special safety-related
characteristics some of which are often not evident
from visual inspection, nor can the protection they
give necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc.
Parts that have special safety characteristics are
identified by a
! in the replacement parts list. Use of
substitute replacement that does not have the same
safety characteristics as the recommended
replacement part in the parts list might create shock,
fire, and/or other hazards. Product safety is under
review continuously and new instructions are issued
whenever appropriate. For the latest information,
always consult the appropriate current service
literature. A subscription to, or additional copies of
service literature may be obtained at a nominal
charge from manufacturer.

LEAD FREE SOLDERING GUIDE
● Lead free solder
With some exception, this product is going to use lead free solder (unleaded) to help preserve the
environment from the September of 2004. Please read these instructions before attempting any soldering
work.
Caution: Always wear safety glasses to prevent fumes or molten solder from getting into the eyes.
Lead free solder can splatter at high temperatures. (600ºC).
■ Lead free solder indicator
There is a F mark made behind the name of PWB or close to its on the printed circuit boards with lead free
solder.
■ Properties of lead free solder
The melting point of lead free solder is 40--50ºC higher than lead solder.
■ Servicing solder
Unleaded solder with an alloy composition of Sn-3.0Ag-0.5Cu is recommended. Although servicing with
leaded solder is possible, there are a few precautions that have to be taken. (Not taking these precautions
may cause the solder to not harden properly, and lead to consequent malfunctions.)
■ Precautions when using leaded solder
● Remove all lead free solder from soldered dots when replacing components.
● If leaded solder should be added to existing unleaded soldered dots , melt the leaded solder thoroughly
and mix it in the unleaded solder after the unleaded soldered dots have been completely melted. (It’s not
permitted to solder directly with soldering iron without solder)
■Servicing soldering iron
A soldering iron with a temperature setting capability (temperature control function) is recommended. The
melting point of unleaded soldering tin is higher than that of leaded ones. Use a soldering iron that maintains
a high stable temperature (large heat capacity) and allows temperature adjustment according to the parts
awaiting serviced to avoid poor servicing performance.
■ Recommended soldering iron
● Soldering iron with temperature control function (temperature range:320--450ºC)
Recommended temperature range per part:
PARTS Soldering iron temperature
Mounting (chips) on mounted PCB 320ºC±30ºC
Mounting (chips) on empty PCB 380ºC±30ºC
Chassis, metallic shield, etc. 420ºC±30ºC
