CHAPTER 1 GENERAL ADJUSTMENTS
SAFETY INSTRUCTIONS
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE “X-RAY RADIATION PRECAUTION”, “SAFETY PRECAU-
TION” AND “PRODUCT SAFETY NOTICE” INSTRUCTIONS BELOW.
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous
X-RAY RADIATION. To avoid such hazards, the high voltage must not be above the specified limit. The nominal
value of the high voltage of this receiver is (A) kV at zero
beam current (minimum brightness) under a 120V AC
power source. The high voltage must not, under any circumstances, exceed (B) kV.
Refer to table-1 for high voltage (A), (B).
(See SETTING & ADJUSTING DATA on page 20)
Each time a receiver requires servicing, the high voltage
should be checked following the HIGH VOLTAGE CHECK
procedure in this manual. It is recommended that the reading of the high voltage be recorded as a part of the service
record. It is important to use an accurate and reliable high
voltage meter.
SAFETY PRECAUTION
WARNING : Service should not be attempted by anyone unfamiliar with the necessary precautions on this receiver. The following are the necessary precautions to be observed before
servicing this chassis.
1. An isolation Transformer should be connected in the power
line between the receiver and the AC line before any service is performed on the receiver.
2. Always discharge the picture tube anode to the CRT conductive coating before handling the picture tube. The picture tube is highly evacuated and if broken, glass fragments
will be violently expelled. Use shatter proof goggles and
keep picture tube away from the unprotected body while
handling.
3. When replacing a chassis in the cabinet, always be certain that all the protective devices are put back in place,
such as; non-metallic control knobs, insulating covers,
shields, isolation resistor-capacitor network etc.
4. Before returning the set to the customer, always perform
an AC leakage current check on the exposed metallic parts
of the cabinet, such as antennas, terminals, screwheads,
metal overlays, control shafts etc. to be sure the set is safe
to operate without danger of electrical shock. Plug the AC
line cord directly into a 120V AC outlet (do not use a line
isolation transformer during this check). Use an AC voltmeter having 5000 ohms per volt or more sensitivity in the
following manner:
PRODUCT SAFETY NOTICE
2. This receiver is equipped with a Fail Safe (FS) circuit which
prevents the receiver from producing an excessively high
voltage even if the B+ voltage increases abnormally. Each
time the receiver is serviced, the FS circuit must be checked
to determine that the circuit is properly functioning, following the FS CIRCUIT CHECK procedure in this manual.
3. The only source of X-RAY RADIATION in this TV receiver
is the picture tube. For continued X-RAY RADIATION protection, the replacement tube must be exactly the same
type tube as specified in the parts list.
4. Some part in this receiver have special safety-related characteristics for X-RAY RADIATION protection. For continued safety, parts replacement should be undertaken only
after referring to the PRODUCT SAFETY NOTICE below.
Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15
µ
F, AC type capacitor, between a known good earth ground
(water pipe, conduit, etc.) and the exposed metallic parts,
one at a time. Measure the AC voltage across the combination of 1500 ohm resistor and 0.15 µF capacitor. Re-
verse the AC plug at the AC outlet and repeat AC voltage
measurements for each exposed metallic part. Voltage
measured must not exceed 0.675 volts rms. This corresponds to 0.45 milliamp. AC. Any value exceeding this limit
constitutes a potential shock hazard and must be corrected
immediately.

each exposed
metallic part.
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics are
often passed unnoticed by a visual inspection and the protection afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this manual and its supplements; electrical components having such features are identified by the
international hazard symbols on the schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement
parts which do not have the same safety characteristics as specified in the parts list may create shock, fire, X-ray radiation or other hazards.

CRT REPLACEMENT
When CRT is replaced, main deflection readjustment and color matching are required.
Perform following procedures.
1. Replace two CRT’s of blue and red.
2. Perform horizontal adjustment for blue and red yokes on base of green CRT data. Mount yoke and velocity mod. coil alignment, pushing towards CRT without gap.
3. Adjust alignment of blue and red. (Refer Alignment adjustment for details.)
4. Rotating centering magnet, adjust CRT centers of red and blue to CRT center of green.
(Picture position adjustment)
5. Adjust HIT and WID data of main deflection, and decide data at the most precise screen comparing to green data.
6. Adjust convergence of screen picture for color matching. Do not move green one at this time.
7. After convergence adjustment of screen picture finishes, replace green CRT.
For green CRT as well, repeat steps 2 to 5 above on bases of red and blue color matching to adjust convergence.
8. Execute TOUCH FOCUS following instructions displayed on the screen after finishing convergence adjustments of all the
colors.
Note: Press button "7" again after "PLEASE PUSH TOUCH FOCUS" has been displayed. Then, TOUCH FOCUS will not be
executed, and the current state of convergence will be displayed.

HOW TO CLEAN LENS AND MIRROR
1. Be sure to remove sand dust with an air brush, etc.
2. When it is stained slightly, breathe upon it and wipe away
with the specified cleaning cloth.
For other stains than the above, wipe the stains away with
the specified cloth into which a cleaning liquid has been
soaked.
The Fail Safe (FS) circuit check is indispensable for the final
check in servicing. Checking should be done following the
steps below.
1. Turn the receiver on.
2. Temporarily short TP- (R) and TP- (X) on the DEF/POWER
Board with a jumper wire.
Raster and sound will disappear.
3. The receiver must remain in this state even after removing
the jumper wire. This is the evidence that the FS circuit is
functioning properly.
4. To obtain a picture again, temporarily turn the receiver off
and allow the FS circuit more than 5 seconds to reset. Then
turn the receiver on to produce a normal picture.
ANODE VOLTAGE MEASURING METHOD
CAUTION: Take extra precaution when measuring this high
voltage. High voltages are also present in
surrounding circuit boards (CRT DRIVE assembly, DEFLECTION assembly, and POWER
SUPPLY assembly).
1. Disconnect the FBT anode cable as outlined below. Measure high voltage at the point where the cable enters the
FBT.
2. Holding the rubber cover firmly, turn it counterclockwise
and check that the lock has been disengaged. (See Fig. b
on page 9.)
3. Determine the extent of the rubber cover before disconnecting the cable.
4. Pull straight up the anode cable to disconnect.
5. When reconnecting the cable, proceed in the reverse order.
After reconnecting, tug on the cable to check that it is secure.

PRGRAMMING CHANNELS INTO THE TV’s CHANNEL MEMORY
When you press CHANNEL y or z on the remote control or
TV front panel, your TV will stop only on the channels stored
in the TV’s channel memory.
Follow the steps below to program channels into the TV’s
channel memory.
Programming channels automatically
Your TV can automatically detect all active channels in your
area and store them in its memory. After the channels are
programmed automatically, you can manually add or erase
individual channels.
Note:
• You must configure the antenna input sources before
programming channels.
• The automatic channel programming process does NOT erase
channels that were previously programmed into the TV’s
memory, but adds newly found channels to the existing set of
programmed channels. To remove a channel from the memory,
you must manually delete it .
• To tune the TV to a channel not programmed in the channel
memory, you must use the Channel Number buttons on the
remote control.
• Programming channels for an antenna input configured for
CABLE will take substantially longer than for an antenna input
configured for ANTENNA. This is normal; however, once
channel programming is completed, you should not have to
repeat the programming process again unless your Cable TV
service lineup changes significantly.
• If you have a CableCARD inserted , channel
programming for ANT 1 is disabled because the CableCARD
automatically loads the Cable channel list in the TV’s channel
memory.
To program channels automatically:
1. Make sure you have configured the antenna input sources.
2. Press MENU and open the SETUP menu.
3. Highlight INSTALLATION and press ENTER. (A new set
of INSTALLATION menu icons will appear on-screen.
4. Open the TERRESTRIAL menu, highlight CHANNEL
PROGRAM, and press ENTER.
5. Highlight ANT 1 or ANT 2, depending on which antenna
input you want to program channels for, and then press
ENTER to start automatic channel programming.

through the channels, the message “Scanning channels,
please wait” appears (as shown above right).
To cancel channel programming, either press EXIT or
highlight ABORT in the on-screen display and press
ENTER.
6. When channel programming is done, press

Manually adding and deleting channels
in the channel memory
After you have programmed the channels automatically, you can
manually add or delete individual channels in the channel
memory.
To add or delete channels in the channel memory:
1. Press MENU and open the SETUP menu.
2. Highlight INSTALLATION and press ENTER. (A new set
of INSTALLATION menu icons will appear on-screen, as
shown in step 3).
To add a channel to the channel memory:
Highlight the unchecked box next to the channel number
you want to add, and then press ENTER to check the box.
To manually add digital subchannels on a physical channel:
Use the Channel Numbers and the Dash (–/100) on the
remote control to enter the channel number (for example,
56–1).
If the channel is found, the number will be added to the list
and the box will be checked.
If the channel is not found, a message will appear.

Protective shutdown in these models will be indicated by the power relay disengaging and the
red power LED blinking at a half second rate. The power cord must then be unplugged and
plugged back in to restore operation. The purpose of this guide is to help narrow the cause of
the shutdown to a single section or circuit. Refer to the correct service manual for additional
information.
The voltage test points indicated in this guide should be measured with a peak-response
meter or an oscilloscope set to DC input. If a peak-response (or min-max meter) is used, set
the sampling time to one millisecond. A higher sampling time could cause errors. Do not use
a normal digital meter because the sampling time will be too long. Since you are attempting
to measure the peak voltage just at the point of shutdown, a normal digital meter might not
give correct readings.
Section One: X-ray protection. The high voltage is sampled at the reference pin of the CR
block, Z450 (at the white wire). This voltage passes through the blue CRT board and is
applied to pin 4 of connector P404 on the DEF/POW board. From there it goes to pin 10 of
Q306 and exits at pin 8. Q306 is a quad op amp that is used for current buffering. The
sampled voltage is then applied to the emitter of Q408 and on to Q409. If the voltage at the
emitter of Q408 exceeds the reference voltage across D490, Q408 and Q409 will be turned
on. This will cause the circuit of Q471, Q472 and Q473 to latch the set into shutdown.
For X-ray shutdown suspect the following components: T461, Z450, C440, C443, C444,
deflection yokes and other components in the horizontal output section.
Section Two:Over-current shutdown. Transistor Q470 and resistor R470 are part of the
over-current sensing circuit for the horizontal output section. The current for the horizontal
output transistor passes through R470. The base to emitter junction of Q470 monitors the
voltage drop across R470. If the current draw of the horizontal output circuit increases, the
voltage drop across R470 will increase. Shutdown will occur when this voltage drop
1.5 volts. (This voltage is very difficult to measure reliably. Since the voltage is measured
across the resistor and neither side of the meter is at ground potential, voltages induced into
the meter leads affect the measurement).
Measure the voltage at resistor R474 on the power/deflection board. Take this measurement
on the end of the resistor toward the rear of the set. If this voltage
exceeds 13.2 volts at the
point of shutdown, then the set is going into over-current shutdown.
For over-current shutdown, suspect components in the horizontal deflection area such as:
Q404, D461, T461, C440, C443, C444, etc.
Section three:Power supply regulation. Problems with the main power supply regulation
can cause the secondary voltages to go too high. If the secondary supply voltage to the
horizontal output section rises above 120 volts, the output transistor will draw excessive
current and indirectly cause an over-current shutdown.
For main power supply regulation problems, suspect components such as: Q801, Q862,
Q881, D880, etc.
