necessary, take corrective action to remove any
potential safety hazard.
PRODUCT SAFETY NOTICE – Many TV electrical
8.
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 in Hitachi service data by shading on
schematics and by ain the parts list. Use of
substitute replacement that does not have the same
safety characteristics as the recommended replacement part in Hitachi service data 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 Hitachi service literature. A subscription to, or
additional copies of service literature may be obtained
at a nominal charge from Hitachi.

Hot Chassis Warning – a. Some TV receiver chassis
5.
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.
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 in the following areas:
sharp edges,
that leads and components do not touch thermally hot

SERVICING PRECAUTIONS
CAUTION: Before servicing instruments covered by this
service data and its supplements and addenda, read and
follow the “Important Safety Instructions” on page 3 of this
publication.
NOTE: If unforeseen circumstances create conflict between
the following servicing precautions and any of the safety
precautions on page 3 of this publication, always follow the
safety precautions. Remember: Safety First.
DP65
7. Do not apply AC power to this instrument and/or any of its
electrical assemblies unless all solid-state device heatsinks are correctly installed.
8. Always connect the test instrument ground lead to the
appropriate instrument chassis ground before connecting
the test instrument positive lead. Always remove the test
instrument ground lead last.
General Servicing Guidelines
1. Always unplug the instrument AC power cord from the AC
power source before:
a. Removing or reinstalling any component, circuit
board, module, or any other instrument assembly.
b. Disconnecting or reconnecting any instrument
electrical plug or other electrical connection.
c. Connecting a test substitute in parallel with an
electrolytic capacitor in the instrument.
CAUTION: A wrong part substitution or incorrect
polarity installation of electrolytic
capacitors may result in an explosion
hazard.
d. Discharging the picture tube anode.
2. Test high voltage only by measuring it with an appropriate
high voltage meter or other voltage measuring device
(DVM, FETVOM, etc.) equipped with a suitable high
voltage probe. Do not test high voltage by “drawing an
arc.” The H.V. Distribution Box has an internal 400M
resistor (bleeder resistor) connected from the high
voltage to ground. After power is removed from the
instrument the high voltage will discharge through the
high voltage bleeder resistor. If the tubes have high
voltage after power is removed, then the bleeder resistor
is defective or the bleeder ground is disconnected.
9. Use with this instrument only the test fixtures specified in
this service data.
CAUTION: Do not connect the test fixture ground strap
to any heatsink in this instrument.
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged
easily by static electricity. Such components commonly are
called Electrostatically Sensitive (ES) Devices. Examples of
typical ES devices are integrated circuits and some fieldeffect transistors and semiconductor “chip” components. The
following techniques should be used to help reduce the
incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor
component or semiconductor-equipped assembly, drain
off any electrostatic charge on your body by touching a
known earth ground. Alternatively, obtain and wear a
commercially available discharging wrist strap device,
which should be removed for potential shock reasons
prior to applying power to the unit under test.
Ω
2. After removing an electrical assembly equipped with ES
devices, place the assembly on a conductive surface
such as aluminum foil, to prevent electrostatic charge
buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or
desolder ES devices.
3. Discharge the picture tube’s anode at any of the R, G, or
B outputs on the H.V. Distribution Box only by (a) first
connecting one end of an insulated clip lead to the
degaussing or kine aquadag grounding system shield at
the point where the picture tube socket ground lead is
connected, and then (b) touch the other end of the
insulated clip lead to the picture tube high voltage
distribution box R, G, or B output, using an insulated
handle to avoid personal contact with high voltage.
4. Do not spray chemicals on or near this instrument or any
of its assemblies.
5. Unless specified otherwise in these service data, clean
electrical contracts by applying the following mixture to
the contacts with a pipe cleaner, cotton-tipped stick or
comparable nonabrasive applicator: 10% (by volume)
Acetone and 90% (by volume) isopropyl alcohol (90%99% strength).
CAUTION: This is a flammable mixture. Unless
specified otherwise in these service data,
lubrication of contacts is not required.
6. Do not defeat any plug/socket B+ voltage interlocks with
which instruments covered by this service data might be
equipped.
TABLE OF CONTENTS
4. Use only can anti-static type solder removal device.
Some solder removal devices not classified as “antistatic” can generate electrical charges sufficient to
damage ES device.
5. Do not use freon-propelled chemicals. These can
generate electrical charges sufficient to damage ES
devices.
6. Do not remove a replacement ES device from its
protective package until immediately before you are
ready to install it. (Most replacement ES devices are
packaged with leads electrically shorted together by
conductive foam, aluminum foil or comparable conductive
material.)
7. Immediately before removing the protective material from
the leads of a replacement ES device, touch the
protective material to the chassis or circuit assembly into
which the device will be installed.
CAUTION: Be sure no power is applied to the chassis or
circuit, and observe all other safety
precautions.
8. Minimize bodily motions when handling unpackaged
replacement ES devices. (Otherwise harmless motion
such as the brushing together of your clothes fabric or the
lifting of your foot from a carpeted floor can generate
static electricity sufficient to damage an ES device.)

SERVICING PRECAUTIONS
General Soldering Guidelines
1. Use a grounded-tip, low-wattage soldering iron and
appropriate tip size and shape that will maintain tip
temperature within the range 500°F to 600°F.
DP65
Removal
1. Desolder and straighten each IC lead in one operation by
gently prying up on the lead with the soldering iron tip as
the solder melts.
2. Use an appropriate lead free solder (see page 10). Lead
solder can be used, but there is a possibility of failure due
to insufficient strength of the solder.
3. Keep the soldering iron tip clean and well-tinned.
4. Thoroughly clean the surfaces to be soldered. Use a
small wire-bristle (0.5 inch or 1.25 cm) brush with a metal
handle. Do not use freon-propelled spray-on cleaners.
5. Use the following desoldering technique.
a. Allow the soldering iron tip to reach normal
temperature (500°F to 600°F).
b. Heat the component lead until the solder melts.
Quickly draw away the melted solder with an antistatic, suction-type solder removal device or with
solder braid.
CAUTION: Work quickly to avoid overheating the
circuit board printed foil.
6. Use the following soldering technique.
a. Allow the soldering iron tip to reach normal
temperature (500°F to 600°F).
b. First, hold the soldering iron tip and solder strand
against the component lead until the solder melts.
c. Quickly move the soldering iron tip to the junction of
the component lead and the printed circuit foil, and
hold it there only until the solder flows onto and
around both the component lead and the foil.
CAUTION: Work quickly to avoid overheating the
circuit board printed foil or components.
2. Draw away the melted solder with an anti-static suctiontype solder removal device (or with solder braid) before
removing the IC.
Replacement
1. Carefully insert the replacement IC in the circuit board.
2. Carefully bend each IC lead against the circuit foil pad
and solder it.
3. Clean the soldered areas with a small wire-bristle brush.
(It is not necessary to reapply acrylic coating to areas.)
1. Remove the defective transistor by clipping its leads as
close as possible to the component body.
2. Bend into a “U” shape the end of each of three leads
remaining on the circuit board.
3. Bend into a “U” shape the replacement transistor leads.
4. Connect to replacement transistor leads to the
corresponding leads extending from the circuit board and
crimp the “U” with long nose pliers to insure metal to
metal contact, then solder each connection.
Power Output Transistor Devices Removal/Replacements
1. Heat and remove all solder from around the transistor
leads.
2. Remove the heatsink mounting screw (if so equipped).
3. Carefully remove the transistor from the circuit board.
d. Closely inspect the solder area and remove any
excess or splashed solder with a small wire-bristle
brush.
IC Removal/Replacement
Some Hitachi unitized chassis circuit boards have slotted
holes (oblong) through which the IC leads are inserted and
then bent flat against the circuit foil. When holes are the
slotted type, the following technique should be used to
remove and replace the IC. When working with boards using
the familiar round hole, use the standard technique as
outlined in paragraphs 5 and 6 above.
4. Insert new transistor in circuit board.
5. Solder each transistor lead, and clip off excess lead.
6. Replace heatsink.
Diode Removal/Replacement
1. Remove defective diode by clipping its leads as close as
possible to diode body.
2. Bend the two remaining leads perpendicularly to the
circuit board.
3. Observing diode polarity, wrap each lead of the new
diode around the corresponding lead on the circuit board.
4. Securely crimp each connection and solder it.
5. Inspect (on the circuit board copper side) the solder joints
of the two “original leads”. If they are not shiny, reheat
them and, if necessary, apply additional solder.

Fuses and Conventional Resistor Removal/Replacement
1. Clip each fuse or resistor lead at top of circuit board
hollow stake.
2. Securely crimp leads of replacement component around
stake 1/8 inch from top.
3. Solder the connections.
CAUTION:Maintain original spacing between the
replaced component and adjacent
components and the circuit board, to
prevent excessive component
temperatures.
Circuit Board Foil Repair
Excessive heat applied to the copper foil of any printed
circuit board will weaken the adhesive that bonds the foil to
the circuit board, causing the foil to separate from, or “liftoff,” the board. The following guidelines and procedures
should be followed whenever this condition is encountered.
In Critical Copper Pattern Areas
High component/copper pattern density and/or special
voltage/current characteristics make the spacing and
integrity of copper pattern in some circuit board areas more
critical than in others. The circuit foil in these areas is
designated as Critical Copper Pattern. Because Critical
Copper Pattern requires special soldering techniques to
ensure the maintenance of reliability and safety standards,
contact your Hitachi personnel.
DP65
At Other Connections
Use the following technique to repair defective copper
pattern at connections other than IC Pins. This technique
involves the installation of a jumper wire on the component
side of the circuit board.
1. Remove the defective copper pattern with a sharp knife.
Remove at least 1/4 inch of copper, to ensure hazardous
condition will not exist if the jumper wire opens.
2. Trace along the copper pattern from both wire sides of
the pattern break and locate the nearest component
directly connected to the affected copper pattern.
At IC Connections
To repair defective copper pattern at IC connections, use the
following procedure to install a jumper wire on the copper
pattern side of the circuit board. (Use this technique only on
IC connections.)
1. Carefully remove the damaged copper pattern with a
sharp knife. (Remove only as much copper as absolutely
necessary.)
2. Carefully scratch away the solder resist and acrylic
coating (if used) from the end of the remaining copper
pattern.
3. Bend a small “U” in one end of a small-gauge jumper wire
and carefully crimp it around the IC pin. Solder the IC
connection.
4. Route the jumper wire along the path of the cut-away
copper pattern and let it overlap the previously scraped
end of the good copper pattern. Solder the overlapped
area, and clip off any excess jumper wire.
3. Connect insulated 20-gauge jumper wire from the
nearest component on one side of the pattern break to
the lead of the nearest component on the other side.
Carefully crimp and solder the connections.
CAUTION: Be sure the insulated jumper wire is
dressed so that it does not touch
components or sharp edges.
Frequency Synthesis (FS) Tuning Systems
1. Always unplug the instrument AC power cord before
disconnecting or reconnecting FS tuning system cables
and before removing or inserting FS tuning system
modules.
2. The FS tuner must never be disconnected from the FS
tuning control module while power is applied to the
instrument.
3. When troubleshooting intermittent problems that might be
caused by defective cable connection(s) to the FS tuning
system, remove the instrument AC power as soon as the
defective connector is found and finish confirming the
bad connection with a continuity test. This procedure will
reduce the probability of electrical overstress of the FS
system semi-conductor components.

SERVICING PRECAUTIONS
DP65
NOTE: These components are affixed with glue. Be careful not to break or damage any foil under the
component or at the pins of the ICs when removing. Usually applying heat to the component for a short
time while twisting with tweezers will break the component loose.
Leadless Chip Components
(surface mount)
Chip components must be replaced with identical
chips due to critical foil track spacing. There are no
holes in the board to mount standard transistors or
diodes. Some chip capacitor or resistor board solder
pads may have holes through the board, however the
hole diameter limits standard resistor replacement to
1/8 watt. Standard capacitors may also be limited for
the same reason. It is recommended that identical
chip components be used. .
Chip resistors have a three digit numerical resistance
code -1st and 2nd significant digits and a multiplier.
Example: 162 = 1600 or 1.6KΩ resistor, 0 = 0Ω
(jumper).
Chip capacitors generally do not have the value
indicated on the capacitor. The color of the component
indicates the general range of the capacitance.
Chip transistors are identified by a two letter code. The
first letter indicates the type and the second letter, the
grade of transistor.
Chip diodes have a two letter identification code as
per the code chart and are a dual diode pack with
either
common anode or common cathode. Check the parts
list for correct diode number.
Component Removal
1. Use solder wick to remove solder from component
end caps or terminals.
2. Without pulling up, carefully twist the component
with tweezers to break the adhesive.
3. Do not reuse removed leadless or chip
components since they are subject to stress
fracture during removal .
Chip Component Installation
1. Put a small amount of solder on the board
soldering pads.
2. Hold the chip component against the soldering
pads with tweezers or with a miniature alligator
clip and apply heat to the pad area with a 30 watt
iron until solder flows. Do not apply heat for more
than 3 seconds

Information for service about lead-free solder introduction
Hitachi introduced lead-free solder to conserve the "Earth Environment".
Please refer to the following before servicing.
(1)
Characteristic of lead-free solder
Melting point of lead free solder is 40-50oC higher than solder containing lead.
(2) Solder for service
Following composition is recommended.
" Sn - 3.0Ag - 0.5Cu " , or " Sn - 0.7 Cu "
Lead solder can be used, but there is a possibility of failure due to insufficient strength of the solder.
Caution when using solder containing lead.

*IMPORTANT
For many of the above adjustments, it is necessary to have an HDTV (1080i or 720P) signal generator, SDTV (480P)
signal generator, as well as the usual NTSC (480i) signal generator.
Hitachi recognizes that few companies offer HDTV or SDTV signal generators and that the cost of these generators is
sometimes prohibitive. For this reason, we suggest the use of a set-top-box for HDTV and SDTV adjustments. Usually,
there is a switch on the set-top-box which enables it to output HDTV (1080i or 720P) or SDTV (480P) signals even with
no input. In this case, the sync is automatically detected by the TV (at the Y-P

needed, the jig screen is not necessary. Use
digital data stored in memory and one color as a
reference (red, green, or blue). DO NOT CLEAR
DATA and WRITE to ROM memory.
2.12.4 Raster position adjustment (minor)
Adjustment preparation
(1) Position adjustment - This will move an entire
color. Use this adjustment to match colors at the
center of the screen. (Active video center from
external signal and physical screen center
should now match from phase adjustment).
(2) Use the buttons below to switch color to adjust.
“INFO” - Green
“0” - Red
“INPUTS” - Blue
Adjustment procedure
(1) Press the button. Extra horizontal lines
appear to confirm raster position mode.
(2) Use the thumb stick to adjust position.
(3) Press again to exit raster position mode.
Notes:(1) Other functions cannot be accessed when
in raster position adjustment mode. Press
and confirm extra horizontal lines
disappear to exit raster position mode.
(2)Press MENU to remove all colors displayed.
2.12.5 Convergence point adjustment
Adjustment preparation
(1) Select color to adjust.
“INFO” - Green
“0” - Red
“INPUTS” - Blue
(2) Use 4, 6, 2, and 5 to move the cursor position
(dotted lines).
(3) Use cursors to move the convergence point.
(4) Three adjustment modes are available:
1.(3x3) Press “INFO” 5 times (only works
when DCU is in uncorrected state)
2.(7x5) Press “0” 5 times
3.(13x9) Press “INPUTS” 5 times
For touch-up, only the (13x9) mode is necessary.
This will adjust every cross-hatch intersection point
on the screen.
For complete adjustment, start with (3x3) mode. This
will adjust center point and eight edge points only,
but will greatly reduce adjustment time. Then use
(7x5) mode, and finally (13x9) mode to finish
convergence.
If “S” distortion appears between cross-hatch
lines repeat (7x5) mode to change calculation
process while adjusting to remove distortion,
then return to (13x9) mode to finish touch-up
convergence.
Adjustment procedure
(1) Receive any NTSC signal.
(2) Start adjustment at the center of the screen.
(3) Continue adjustment at next closest position.
(4) Adjust center area first, ending with edge sections.
(5) Press GUIDE button to perform calculation
operation. This process will take about 1 second and
no picture will be seen at this time.
(6) After interpolation, check convergence again and
repeat (1)-(5) if necessary.
(7) When convergence is acceptable, press ASPECT to
write data to ROM memory. ROM WRITE? is
displayed to alarm system that ROM will be
overwritten with new data. Press the ASPECTbutton
again to write displayed data to ROM.
(8) DATA WRITE TO ROM will take approximately 4
seconds and no picture will be displayed.
(9) Green dots will be displayed when operation is
completed.
(10) Push MUTE to return to convergence pattern , then
confirm again convergence if is acceptable.
(11) Press ASPECT (ROM WRITE) mode, then press
to initialize sensor data positions.
Notes: (1) Display only green for easier adjustment and
match to jig screen. Press “MENU”, THEN
PRESS “INFO”.
(2) Perform interpolation and data write to ROM
after green adjustment. Once green has been
confirmed to match jig screen, the jig screen can
be removed. Do not readjust the green color
after jig screen has been removed. This is now
your reference color.
(3) Display green and red only and match red to
green.
(4) Display all colors and match blue to green and
red. Touch-up red color if necessary.
(5) Existing DATA in ROM can be read by pressing
the DA Y/NIGHTbutton 2 times. This data can be
used after replacing a component (CRT, DY,
etc.) Where complete convergence adjustment
is not necessary, be careful not to overwrite this
data.
DO NOT write cleared RAM data into ROM or a
complete convergence adjustment will be
necessary. Remember to try MAGIC FOCUS
before starting convergence adjustment to
minimize adjustment time.
(6) To confirm and fine tune the convergence at the
edge of the screen, press the button on the
remote control while in the digital convergence
adjustment mode (DCAM) for additional lines at
the edge of the screen. Fine tune the edge
convergence as necessary. To exit, press
again.
