WARNINGS AND CAUTIONS
CAUTION
Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield, or carbon painted on the CRT,
after removing the anode.
WARNING!!
An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis. The chassis of
this receiver is directly connected to the AC power line.
! SAFETY-RELATED COMPONENT WARNING!!
Components identified by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for
safe operation. Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements
published by Sony. Circuit adjustments that are critical for safe operation are identified in this manual. Follow these procedures
whenever critical components are replaced or improper operation is suspected.
ATTENTION!!
Apres avoir deconnecte le cap de l’anode, court-circuiter l’anode du tube cathodique et celui de l’anode du cap au chassis metallique
de l’appareil, ou la couche de carbone peinte sur le tube cathodique ou au blindage du tube cathodique.
Afin d’eviter tout risque d’electrocution provenant d’un chássis sous tension, un transformateur d’isolement doit etre utilisé lors de tout
dépannage. Le chássis de ce récepteur est directement raccordé à l’alimentation du secteur.
! ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!
Les composants identifies par une trame et par une marque ! sur les schemas de principe, les vues explosees et les listes de
pieces sont d’une importance critique pour la securite du fonctionnement. Ne les remplacer que par des composants Sony dont
le numero de piece est indique dans le present manuel ou dans des supplements publies par Sony. Les reglages de circuit dont
l’importance est critique pour la securite du fonctionnement sont identifies dans le present manuel. Suivre ces procedures lors de
chaque remplacement de composants critiques, ou lorsqu’un mauvais fonctionnement suspecte.

SAFETY CHECK-OUT
Leakage Test
The AC leakage from any exposed metal part to earth ground and from
all exposed metal parts to any exposed metal part having a return to
chassis, must not exceed 0.5 mA (500 microamperes). Leakage current
can be measured by any one of three methods.
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly soldered
connections. Check the entire board surface for solder splashes and
bridges.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to use these
instructions.
2. Check the interboard wiring to ensure that no wires are “pinched” or
touching high-wattage resistors.
2. A battery-operated AC milliampmeter. The Data Precision 245 digital
multimeter is suitable for this job.
3. Check that all control knobs, shields, covers, ground straps, and
mounting hardware have been replaced. Be absolutely certain that
you have replaced all the insulators.
3. Measuring the voltage drop across a resistor by means of a VOM
or battery-operated AC voltmeter. The “limit” indication is 0.75 V,
so analog meters must have an accurate low voltage scale. The
Simpson’s 250 and Sanwa SH-63TRD are examples of passive VOMs
that are suitable. Nearly all battery-operated digital multimeters that
have a 2 VAC range are suitable (see Figure A).
4. Look for unauthorized replacement parts, particularly transistors,
that were installed during a previous repair. Point them out to the
customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious signs of
deterioration. Point them out to the customer and recommend their
replacement.
6. Check the line cords for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values. Make sure
your instruments are accurate; be suspicious of your HV meter if sets
always have low HV.
8. Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts for AC leakage. Check leakage
as described below.
How to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground; the cover-plate retaining
screw on most AC outlet boxes is also at earth ground. If the retaining
screw is to be used as your earth ground, verify that it is at ground
by measuring the resistance between it and a cold-water pipe with an
ohmmeter. The reading should be zero ohms.
If a cold-water pipe is not accessible, connect a 60- to 100-watt troublelight (not a neon lamp) between the hot side of the receptacle and the
retaining screw. Try both slots, if necessary, to locate the hot side on the
line; the lamp should light at normal brilliance if the screw is at ground
potential (see Figure B).

SELF-DIAGNOSTIC FUNCTION
Self Diagnosis
Supported model
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to flash. The number
of times the LED flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER LED flash indicators is listed in the
instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the Remote Commander can be used to review
the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
Diagnostic Test Indicators
When an error occurs, the STANDBY/TIMER LED will flash a set number of times to indicate the possible cause of the problem. If there is more than
one error, the LED will identify the first of the problem areas.
Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

SECTION 6: EXPLODED VIEWS
Components not identified by a part number or
description are not stocked because they are seldom
required for routine service.
The component parts of an assembly are indicated by
the reference numbers in the far right column of the parts
list and within the dotted lines of the diagram.
NOTE: The components identified by shading and ! mark are critical for safety.
Replace only with part number specified.
* Items marked with an asterisk are not stocked since
they are seldom required for routine service. Expect
some delay when ordering these components.
NOTE: Les composants identifies par un trame et une marque ! sont critiques pour
la securite. Ne les remplacer que par une piece portant le numero specifie.

WARNING
To reduce the risk of fire or electric shock, do not expose the TV to rain or moisture.
CAUTION

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
This symbol is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to persons.
This symbol is intended to alert the user to the presence of important operating
and maintenance (servicing) instructions in the literature accompanying the
appliance.
Note to the CATV Installer
This reminder is provided to call the CATV system installer’s attention to Article 820-40 of
the NEC that provides guidelines for proper grounding and, in particular, specifies that the
cable ground shall be connected to the grounding system of the building as close to the
point of cable entry as practical.
SAFETY PRECAUTIONS
Operate the TV only on 120 V AC.
One blade of the power plug is wider than the other for safety purposes and will fit
into the power outlet only one way. If you are unable to insert the plug fully into the
outlet, contact your dealer.
If any liquid or solid object falls into the TV, unplug it and have it checked by qualified
personnel before operating it further.
CAUTION
When using TV games, computers, and similar products with your TV, keep the brightness
and contrast functions at low settings. If a fixed (non-moving) pattern is left on the screen
for long periods of time at a high brightness or contrast setting, the image can be
permanently imprinted onto the screen. Continuously watching the same channel can cause
the imprint of station logos onto the TV screen. These types of imprints are not covered by
your warranty because they are the results of misuse.
To reduce the risk of electric shock, do not use this polarized plug with an
extension cord, receptacle, or other outlet unless the blades can be fully
inserted to prevent blade exposure.
Connecting Additional Equipment
You are cautioned that any changes or modifications not expressly approved in this
manual could void your authority to operate this equipment.

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/TV technician for help.
Protecting the TV
To prevent internal heat build-up, do not block the ventilation openings.
Do not install the TV in a hot or humid place, or in a place subject to excessive dust or
mechanical vibration.
Note on Caption Vision
This television receiver provides display of television closed captioning in accordance with
§ 15.119 of the FCC rules.
Use of this television for other than private viewing of programs broadcast on UHF or VHF
or transmitted by cable companies for the use of the general public may require
authorization from the broadcaster-cable company and/or program owner.

User Guide
Important Safeguards
For your protection, please read these instructions completely, and keep this manual for
future reference. Carefully observe and comply with all warnings, cautions and instructions
placed on the set, or described in the operating instructions or service manual.
WARNING
To guard against injury, the following basic safety precautions should be observed in the
installation, use, and servicing of the set.
Use
Power Sources
This set should be operated only from the
type of power source indicated on the
serial/model plate. If you are not sure of
the type of electrical power supplied to
your home, consult your dealer or local
power company. For those sets designed to
operate from battery power, refer to the
operating instructions.
Grounding or Polarization
This set is equipped with a polarized AC
power cord plug (a plug having one blade
wider than the other), or with a three-wire
grounding type plug (a plug having a third
pin for grounding).
Follow the instructions below:
For the set with a polarized AC power
cord plug
This plug will fit into the power outlet only
one way. This is a safety feature. If you are
unable to insert the plug fully into the
outlet, try reversing the plug. If the plug
should still fail to fit, contact your
electrician to have a suitable outlet
installed. Do not defeat the safety purpose
of the polarized plug by forcing it in.
Alternate Warning
For the set with a three-wire
grounding type AC plug
This plug will only fit into a groundingtype power outlet. This is a safety feature.
If you are unable to insert the plug into the
outlet, contact your electrician to have a
suitable outlet installed. Do not defeat the
safety purpose of the grounding plug.
Connecting Additional Equipment
Overloading
Cleaning
Do not overload wall outlets, extension
cords or convenience receptacles beyond
their capacity, since this can result in fire or
electric shock. Always turn the set off
when it is not to be used. When the set is
left unattended and unused for long
periods of time, unplug it from the wall
outlet as a precaution against the
possibility of an internal malfunction that
could create a fire hazard.
Unplug the set from the wall outlet before
cleaning or polishing it. Do not use liquid
cleaners or aerosol cleaners. Use a cloth
lightly dampened with water for cleaning
the exterior of the set.
Object and Liquid Entry
Never push objects of any kind into the set
through the cabinet slots as they may touch
dangerous voltage points or short out parts
that could result in a fire or electric shock.
Never spill liquid of any kind on the set.
If a snapping or popping sound from a TV
set is continuous or frequent while the TV
is operating, unplug the TV and consult
your dealer or service technician. It is
normal for some TV sets to make
occasional snapping or popping sounds,
particularly when being turned on or off.

etc.
User Guide
Accessories
Do not place the set on an unstable cart,
stand, tripod, bracket, table, or shelf. The
set may fall, causing serious injury to a
child or an adult, and serious damage to
the set. Use only a cart or stand
recommended by the manufacturer for the
specific model of TV any mounting of the
product should follow the manufacturer’s
instructions, and should use a mounting
accessory recommended by the
manufacturer. An appliance and cart
combination should be moved with care.
Quick stops, excessive force, and uneven
surfaces may cause the appliance and cart
combination to overturn.
•
Never place the set in a confined
space, such as a bookcase, or built-in
cabinet, unless proper ventilation is
provided.
•
Do not place the set near or over a
radiator or heat register, or where it
is exposed to direct sunlight.
Power-Cord Protection
Ventilation
The slots and openings in the cabinet and
in the back or bottom are provided for
necessary ventilation. To ensure reliable
operation of the set, and to protect it from
overheating, these slots and openings must
never be blocked or covered.
•

or abuse.
Connecting Additional Equipment
Grounding or Polarization
This set may be equipped with a polarized alternating current line plug (a plug having one
blade wider than other). This plug will fit into the power outlet only one way. This is a
safety feature. If you are unable to insert the plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit, contact you electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug.
Antennas
Outdoor Antenna Grounding
If an outdoor antenna is installed, follow the precautions below. An outdoor antenna
system should not be located in the vicinity of overhead power lines or other electric light or
power circuits, or where it can come in contact with such power lines or circuits.
WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM, EXTREME CARE SHOULD
BE TAKEN TO KEEP FROM CONTACTING SUCH POWER LINES OR CIRCUITS AS
CONTACT WITH THEM IS ALMOST INVARIABLY FATAL.
Be sure the antenna system is grounded so as to provide some protection against voltage
surges and built-up static charges. Section 810 of the National Electrical Code (NEC) in USA
and Section 54 of the Canadian Electrical Code in Canada provides information with respect
to proper grounding of the mast and supporting structure, grounding of the lead-in wire to
an antenna discharge unit, size of grounding conductors, location of antenna discharge unit,
connection to grounding electrodes, and requirements for the grounding electrode.
Antenna Grounding According to the NEC
Refer to section 54-300 of Canadian Electrical Code for Antenna Grounding.

Lightning
For added protection for this television receiver during a lightning storm, or when it is left
unattended and unused for long periods of time, unplug it from the wall outlet and
disconnect the antenna. This will prevent damage to the receiver due to lightning and
power-line surges.
User Guide
Service
Damage Requiring Service
Unplug the set from the wall outlet and
refer servicing to qualified service
personnel under the following conditions:
•
When the power cord or plug is
damaged or frayed.
•
•
When the set exhibits a distinct
change in performance — this
indicates a need for service.
Servicing
Do not attempt to service the set yourself
since opening the cabinet may expose you
to dangerous voltage or other hazards.
Refer all servicing to qualified service
personnel.
If liquid has been spilled into the set
or objects have fallen into the
product.
Replacement Parts
•
If the set has been exposed to rain or
water.
•
If the set has been subject to
excessive shock by being dropped,
or the cabinet has been damaged.
When replacement parts are required, be
sure the service technician certifies in
writing that he has used replacement parts
specified by the manufacturer that have the
same characteristics as the original parts.
Unauthorized substitutions may result in
fire, electric shock, or other hazards.
Safety Check
•
If the set does not operate normally
when following the operating
instructions. Adjust only those
controls that are specified in the
operating instructions. Improper
adjustment of other controls may
result in damage and will often
require extensive work by a
qualified technician to restore the set
to normal operation.
Upon completion of any service or repairs
to the set, ask the service technician to
perform routine safety checks (as specified
by the manufacturer) to determine that the
set is in safe operating condition, and to so
certify. When the set reaches the end of its
useful life, improper disposal could result
in a picture tube implosion. Ask a qualified
service technician to dispose of the set.

PRINTING THE SERVICE MANUAL
The PDF of this service manual is not designed to be printed from cover to cover. The pages vary in size, and must therefore be printed in sections
based on page dimensions.
NON-SCHEMATIC PAGES
Data that does NOT INCLUDE schematic diagrams are formatted to 8.5 x 11 inches and can be printed on standard letter-size and/or A4-sized paper.
SCHEMATIC DIAGRAMS
The schematic diagram pages are provided in two ways, full size and tiled. The full-sized schematic diagrams are formatted on paper sizes between
8.5” x 11” and 18” x 30” depending upon each individual diagram size. Those diagrams that are LARGER than 11” x 17” in full-size mode have been
tiled for your convience and can be printed on standard 11” x 17” (tabloid-size) paper, and reassembled.
TO PRINT FULL SIZE SCHEMATIC DIAGRAMS
If you have access to a large paper plotter or printer capable of outputting the full-sized diagrams, output as follows:
1) Note the page size(s) of the schematics you want to output as indicated in the middle window at the bottom of the viewing screen.
2) Go to the File menu and select Print Set-up. Choose the printer name and driver for your large format printer. Confirm that the printer settings
are set to output the indicated page size or larger.
3) Close the Print Set Up screen and return to the File menu. Select “Print...” Input the page number of the schematic(s) you want to print in the
print range window. Choose OK.
TO PRINT TILED VERSION OF SCHEMATICS
Schematic pages that are larger than 11” x 17” full-size are provided in a 11” x 17” printable tiled format near the end of the document. These can be
printed to tabloid-sized paper and assembled to full-size for easy viewing.
If you have access to a printer capable of outputting the tabloid size (11” x 17”) paper, then output the tiled version of the diagram as follows:
1) Note the page number(s) of the schematics you want to output as indicated in the middle window at the bottom of the viewing screen.
2) Go to the File menu and select Print Set-up. Choose the printer name and driver for your printer. Confirm that the plotter settings are set to output
11” x 17”, or tabloid size paper in landscape (
) mode.
3) Close the Print Set Up screen and return to the File menu. Select “Print...” Input the page number of the schematic(s) you want to print in the
print range window. Choose OK.
TO PRINT SPECIFIC SECTIONS OF A SCHEMATIC
To print just a particular section of a PDF, rather than a full page, access the Graphics Select tool in the Acrobat Reader tool bar.
1) To view the Graphics Select Tool, press and HOLD the mouse button over the Text Select Tool which looks like: T
This tool will expand to reveal to additional tools.
Choose the Graphics Select tool by placing the cursor over the button on of the far right that looks like:
2) After selecting the Graphics Select Tool, place your cursor in the document window and the cursor will change to a plus (+) symbol. Click and
drag the cursor over the area you want to print. When you release the mouse button, a marquee (or dotted lined box) will be displayed outlining
the area you selected.
3) With the marquee in place, go to the file menu and select the “Print...” option. When the print window appears, choose the option under the section
called “Print Range” which says “Selected Graphic”.
Select OK and the output will print only the area that you outlined with the marquee.

ON-SCREEN SEARCH OPTION
All of the text within the service manual PDF is content searchable. This means that you can enter any text, word, phrase or reference number that
appears in the manual, and the PDF software will search, find and move the cursor to the location where you requested text first appears. This feature
can be particularly useful in locating components on a specific schematic or printed wire circuit board (PWB) diagrams.
Follow these steps to effectively locate a component on a schematic diagram:
1) Locate the schematic you want to search by clicking on the corresponding bookmark on the left side of the screen. The view on the right of the
screen will then jump to the desired schematic page.
2) Magnify the diagram to at least 400% before conducting a component search. This will enable you to easily view the reference number when
it is highlighted on screen. To do this, click on the magnifying glass button on the tool bar at the top of the screen. Move the cursor over the
diagram and RIGHT click you mouse. Select the 400% magnification option on the pop-up menu. Click on the button with the icon of the open
hand to deactivate the magnification tool
3) Search the diagram (or the entire manual) by clicking on the binocular button tool at the top of the screen. The “Find” window will appear and
allow you to type in your desired text. Type in a reference designator, such as R502, and click on the “Find” button. If the component is not on the
diagram, but is listed anywhere else in the manual, the cursor will jump to the first location the text is found in the file. To find another instance of
that same text, click on the binocular button again and select “Find Again.”
