Proper service and repair is important to the safe, reliable operation of all
Funai Equipment. The service procedures recommended by Funai and described in this service manual are effective methods of performing service
operations. Some of these service special tools should be used when and
as recommended.
It is important to note that this service manual contains various CAUTIONS
and NOTICES which should be carefully read in order to minimize the risk of
personal injury to service personnel. The possibility exists that improper
service methods may damage the equipment. It also is impo rtant to understand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Funai
could not possibly know, evaluate and advice the service trade of all conceivable ways in which service might be done or of the possible hazardous
consequences of each way. Consequently, Funai has not undertaken any
such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recommended by Funai must first use all precautions thoroughly so that neither his safety nor the safe operation of the
equipment will be jeopardized by the service method selected.

IMPORTANT SAFETY PRECAUTIONS
Prior to shipment from the fact ory, our products are stri ctly insp ected for recogni zed pr oduct sa fety and elec trical
codes of the countries in which they are to be sold. Howev er, in order to ma intain such c ompliance, it is equally
important to implement the following precautions when a set is being serviced.
Safety Precautions for TV Circuit
1. Before returning an instrument to the custom -
er, alwa ys make a safety check of the entire instru-
ment, including, but not limited to, the following
items:
a. Be sure that no built-in protective devices are de-
fective and have been defeated during servicing.
(1) Protective shields ar e p rovid ed o n thi s ch ass i s
to protect both the technician and the customer.
Correctly replace all missing protective shields, including any removed for servicing convenience.
(2) When reinstalli ng the cha ssis and/o r other as sembly in the cabinet, be sure to put back in place
all protective devices, including but not lim ited to,
nonmetallic control knobs, insulating fishpapers,
adjustment and com part ment covers/shields, and
isolation resistor/capacitor networks. Do not oper-
ate 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 the 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 acr oss the two AC plug prongs.
Place the instrument AC switch in the o n position.
Connect one lead of an oh mmeter to the A C plug
prongs tied together and to uch the other ohmme ter 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 mego hm or greater than 5 .2 megohm, an abnormality exists that must be corrected
before the instrument is r eturne d to the cu stomer .
Repeat this test with the ins trument AC switch in
the off position.
d. Leakage Current Hot Check - With the instru-
ment completely reassembled, plug the AC line
cord directly into a 120V AC outlet. (Do not use an
isolation transformer d uring thi s test.) Use a leak-
age current tester or a me tering syst em that com plies with American National Standards Institute
(ANSI) C101.1 Leakage Current for Appliances
and Underwriters Laborat ories (UL) 1410, (50.7).
With the instrument AC switc h first in the on posi tion and then in the o ff position, measure from a
known earth ground (metal water pipe, conduit,
etc.) to all exposed metal parts of the instrument
(antennas, handle br ackets, metal cabi net, screw
heads, metallic overlay s, control shafts, etc.), es pecially any exposed metal parts that offer an electrical return path to the chassis. Any current
measured must not excee d 0.5 milli-ampere. Re verse the instrument power cord plug in the outlet
and repeat the test.

e. X-Radiation and High Voltage Limits - Because
the picture tube i s the prim ary potentia l source of
X-radiatio n in solid- state TV receiver s, it is s pecially constructed to prohibit X-radiation emissions.
For continued X-radiation pr otection, the replacement picture tube must be the same type as the
original. Also, because the picture tube shields
and mounting hardware perform an X-radiation
protection function, they must be correctly in place.
High voltage must be mea su re d ea ch tim e s er vic -

ing is performed that inv olves B+, horizontal deflection or high voltage. Correct operation of the Xradiation protection circuits also must be reconfirmed each time they are serviced. (X-radiation
protection circuits also may be called "horiz ontal
disable" or "hold do wn.") R ead a nd a ppl y th e hi gh
voltage limits a nd, if the chassis is so e quipped,
the X-radiation protection circuit specifications given on instrument labe ls and i n the P roduct S afety
& X-Radiation Warning note on the service data
chassis schematic. High voltage is maintained
within specified limits by close tolerance safety-related components/adjus tme nts in th e hig h-vo lta ge
circuit. If high voltage exceeds specified limits,
check each component specified on the chassis
schematic and take corrective action.
2. Read and comply with all caution and safety-related notes on or inside th e receiver cabi net, on the
receiver chassis, or on the picture tube.
3. Design Alteration Warning - Do not alter or add
to the mechanical or electrical design of this TV receiver. Design alterations and additions, including,
but not limited to circuit modificatio ns and the addition of items such as auxiliary audio and/or video
output connections, mig ht alter the safety ch aracteristics of this receiver and create a hazard to the
user. Any design alter ations or addition s will void
the manufacturer's warr anty and may make you,
the servicer, responsible for personal injury or
property damage resulting therefrom.
4. Picture Tube Implosion Protection Warning -
The picture tube in this receiver employs integral
implosion protection. For continued implosion protection, replace the pic ture tube only with one of
the same type numbe r. Do not rem ove, install , or
otherwise handle the picture tube in any ma nner
without first putting on shatterproof goggles
equipped with side shields. People not so
equipped must be ke pt safely away while p icture
tubes are handled. Keep the picture tube away
from your body. Do not handl e the pictur e tu be b y
its neck. Some "in-line" picture tubes are equipped
with a permanently at tached deflection yoke ; because of potential hazard, do not try to remove
such "permanently attached" yokes from the picture tube.
5. Hot Chassis Warning -
a. Some TV receiver chassis are electrically connect-
ed directly to one conduc tor of th e AC powe r cor d
and maybe safety-serviced without an isolation
transformer only i f the AC power plug i s inserted
so that the chassis is connected to the ground side
of the AC power source. To confi rm that the AC
power plug is ins erted correctly, with an AC voltmeter, measure 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.
b. Some TV receiver chassis normally have 85V
AC(RMS) between ch assis and earth ground regardless of the AC plug polarity. This chassis can
be safety-serviced only with an isolation transformer inserted in the power line between the receiver
and the AC power so urce , for both pers onnel and
test equipment protection.
c. Some TV receiver chassis have a secondary
ground system in addition to the main chassis
ground. This se conda ry gro und s ystem is no t iso lated from the AC power line. The two ground systems are electrically separated by insulation
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:a.
near sharp edges,b. near thermally hot parts-be
sure that leads and components do not touch thermally hot parts, c. the AC supply,d. high voltage,
and,e. antenna wir ing. Always insp ect in all ar eas
for pinched, out of plac e, or frayed wiring. C heck
AC power cord for damage.
7. Components, parts, and/or wiring that app ear to
have overheated or are otherwise damaged
should be replaced with components, parts, or wiring that meet origin al specifications. Additiona lly,
determine the cause of ov erheating and/or damage and, if nece ss ar y, ta ke corre ct i ve ac ti o n to remove any potential safety hazard.
8. Product Safety Notice - Some electrical and mechanical parts have s pecia l safety- relat ed char acteristics which are often not evident from visual
inspection, nor can the protection they give necessarily be obtained by replaci ng them with components rated for higher voltage, wattage, etc.. Parts
that have special safety characteristics are identified by a ( # ) on schematics and in parts lists. Use
of a substitute replacement that does not have the
same safety characteristics as the recommended
replacement part might create sh ock, fire, and/or
other hazards. The product's safety is under review continuously and new instructions are issued
whenever appropriate . Prior to shi pment from the
factory, our products are strictly inspected to confirm they comply with the recognized product safety and electrical codes of the countries in which
they are to be sold. Howev er, in orde r to mai ntain
such compliance , it is equally i mportant to imple ment the following precautions when a set is being
serviced.
2-2L6115IMP
Precautions during Servicing
A. Parts identified b y the ( # ) symbo l are c ritica l for
safety.
Replace only with part number specified.
B. In addition to safety, othe r parts and assemblies
are specified for conformance with regulations applying to spurious radiati on. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers
4) Insulators for transistors.
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of
wires securely abo ut the terminals before so ldering.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fusible resistor s, etc.)
G. Check that replaced wires do not contact sharp
edged or pointed parts.
H. When a power cord has been replaced, check that
5~6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Use care that foreign objects (screws, solder drop-
lets, etc.) do not remain inside the set.
K. Crimp type wire connector
The power transform er uses crimp type connec-
tors which connect the power cord and the primary
side of the transformer. When replacing the trans-
former, follow these step s carefully and precis ely
to prevent shock hazards.
Replacement procedure
1) Remove the old connector by cutti ng the wires at
a point close to the connector.
Important: Do not re-use a connector (discard it).
2) Strip about 15 mm of the insulation fro m the end s
of the wires. If the wires are stranded, twist the
strands to avoid frayed conductors.
3) Align the lengths of the wires to be connected. Insert the wires fully into the connector.
4) Use the crimping tool to crimp the metal sleeve at
the center position . Be sure to crimp fully to the
complete closure of the tool.
L. When connecting or disconnecting the internal
connectors, first, discon nect the AC plug from the
AC supply outlet.
2-3L6115IMP
Safety Check after Servicing
Examine the area surrounding the repaired location
for damage or deterioration. Observe that screws,
parts and wires have been returned to original positions. Afterwards, perform the following tests and confirm the spec ified values in or der to verify comp liance
with safety standards.
1. Clearance Distance
When replacing primary circuit components, confirm
specified clearance distance (d) and ( d') between sol dered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)

Standard Notes
Many electrical and mechanical parts in this chassis have special characteristics. These characteristics often
pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts that have these special safety character ist ics are
identified in this ma nual and its supplements; electr ical components having such features are ident ified by the
mark " # " in the schematic diagram and the parts list. Before replacing any of these components, read the parts

IMPORTANT SAFETY NOTICE
Proper service and repair is important to the safe, reliable operation of all
Funai Equipment. The service procedures recommended by Funai and described in this service manual are effective methods of performing service
operations. Some of these service special tools should be used when and
as recommended.
It is important to note that this service manual contains various CAUTIONS
and NOTICES which should be carefully read in order to minimize the risk of
personal injury to service personnel. The possibility exists that improper
service methods may damage the equipment. It also is important to understand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Funai
could not possibly know, evaluate and advice the service trade of all conceivable ways in which service might be done or of the possible hazardous
consequences of each way. Consequently, Funai has not undertaken any
such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recommended by Funai must first use all precautions thoroughly so that neither his safety nor the safe operation of the
equipment will be jeopardized by the service method selected.

SCHEMATIC DIAGRAMS / CBA'S AND TEST POINTS
Standard Notes
Many electrical and mechanical parts in this chassis have special characteristics. These characteristics often
pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts that have these special safety characteristics are
identified in this manual and its supplements; electrical components having such features are identified by the
mark " # " in 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 that do not have the same safety characteristics as specified in the parts list may create shock, fire, or other hazards.
Note:
1. Do not use the part number shown on these drawings for ordering. The correct part number is shown in the
parts list, and may be slightly different or amended since these drawings were prepared.
2. All resistance values are indicated in ohms (K=10
3. Resistor wattages are 1/4W or 1/6W unless otherwise specified.

LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON
THE FOLLOWING PAGES:
1. CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME
TYPE_A,_V FUSE.
ATTENTION: UTILISER UN FUSIBLE DE RECHANGE DE MÊME TYPE DE_A,_V.
2. CAUTION:
Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F601) is blown, first check to see that all components in the power supply circuit are not defective
before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power supply circuit to fail.
3. Note:
(1) Do not use the part number shown on the drawings for ordering. The correct part number is shown in the
parts list, and may be slightly different or amended since the drawings were prepared.
(2) To maintain original function and reliability of repaired units, use only original replacement parts which are
listed with their part numbers in the parts list section of the service manual.
4. Wire Connectors
(1) Prefix symbol "CN" means "connector" (can disconnect and reconnect).
(2) Prefix symbol "CL" means "wire-solder holes of the PCB" (wire is soldered directly).
5. Voltage indications on the schematics are as shown below:
Plug the TV power cord into a standard AC outlet.:

Because a hot chassis ground is present in the power
supply circuit, an isolation transformer must be used.
Also, in order to have the ability to increase the input
slowly,when troubleshooting this type power supply
circuit, a variable isolation transformer is required.
