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 identifi ed 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 identifi ed 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.
Afi n 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.

SAFETY CHECK-OUT
KV-27FS120/29FA310/29FS120
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.
2. Check the interboard wiring to ensure that no wires are “pinched” or
touching high-wattage resistors.
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.
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 specifi ed 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.
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.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instructions.
2. A battery-operated AC milliampmeter. The Data Precision 245
digital multimeter is suitable for this job.
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).
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
trouble- light (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 fl ash. The number
of times the LED fl ashes translates to a probable source of the problem. A defi nition of the STANDBY/TIMER LED fl ash 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 fl ash 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 fi rst 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”.

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.
✍
You are cautioned that any changes or modifications
not expressly approved in this manual could void
your authority to operate this equipment.

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 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 o nly 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 still fails to fit, contact
your electrician to replace your obsolete outlet. Do not defeat
the safety purpose of the polarized plug.
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 still fails 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 W arning
For the set with a thr ee- wir e gr oundin g type A C plug
This plug will only fit into a
grounding-type 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.
Overloading
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.
Do not disconnect the antenna or the power cord during a
heavy storm. Lightning may strike while you are holding
the cable or cord, causing serious injury. Turn off your TV
and wait for the weather to improve.
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.
Attachments
Do not use attachments not recommended
by the manufacturer, as they may cause
hazards.
Do not place any objects, especially heavy
objects, on top of the set. The object may
fall from the set, causing injury.
Cleaning
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.
If a snapping or popping sound from a TV set

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
Do not allow anything to rest on or roll over the
power cord, and do not place the set where the
power cord is subject to wear or abuse.
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.

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.
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.
•If liquid has been spilled
into the set or objects have
fallen into the product.
•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.
•
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.
•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.
Replacement Parts
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.
Safet y C h eck
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.
