This addendum is due to the change of the Core Block height of model 53UWX10B and 61UWX10B
for improving the production process.
Due to this change, the model name is changed from
53UWX10B and 61UWX10B TO 53UWX10BA AND 61UWX10BA respectively. All features/adjust-
ments for 53UWX10BA, 61UWX10BA are the same as 53UWX10B and 61UWX10B. Please refer to
model 53UWX10B, 61UWX10B Service Manual PA No. 0147 issued in June 2001 when servicing
models 53UWX10BA and 61UWX10BA.
This parts list only lists parts which are different from service manual PA No. 0147.

accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
¥ Reorient or relocate the receiving antenna.
¥ Increase the separation between the equipment and the receiver.
¥ Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
¥ Consult the dealer or an experienced radio/television technician for help.

IMPORTANT SAFETY INSTRUCTION
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 removed 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 fishpaper,
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. Servicers who defeat 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
removed from any AC 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 ohmmeter to the AC plug prongs tied
together and touch the other ohmmeter lead in turn to
each tuner antenna input, exposed terminal screw
and, if applicable, to the coaxial connector. If the
measured resistance is less than 1.0 megohms or
greater than 5.2 megohms, 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 120V AC outlet. (Do not use an isolation
transformer during this test.) Use a leakage current
tester or a metering system that complies with
American National Standards Institute (ANSI) C101.0
Leakage Current for Appliances and Underwriters
Laboratories (UL) 1410, (50.7). With the instrument
AC switch first in the on position and then in the off
position, measure from a known earth ground (metal
waterpipe, 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 0.5 milliamps.
Reverse the instrument power cord plug in the outlet
and repeat 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 circuit for clearly indicating that voltage has
increased in excess of a predetermined value.
Comply will 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 31.5 kV. In
case any component having influence on high voltage
is replaced, confirm that the high voltage with
maximum contrast is lower than 31.5 kV.
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 power switch off without fail before the
connection to the anode button is made.

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 measure-
ments in a receiver with a problem of excessive high
voltage, avoid being unnecessarily close to the pic-
ture 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
1. This receiver is provided with X-ray shield plates
for protection against X-radiation. Do not remove
X-ray shield plates A, B, or C shown in Fig. 1
unnecessarily,
when
troubleshooting
and/or
making test measurements.
2. 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.
