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.

IMPORTANT SAFETY PRECAUTIONS
Product Safety Notice
Some electrical and mechanical parts have special
safety-related characteristics 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 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 shock, fire, and/or other
hazards. The Product’s Safety is under review continuously and new instructions are issued whenever
appropriate. Prior to shipment from the factory, our
products are carefully inspected to confirm with the
recognized product safety and electrical codes of the
countries in which they are to be sold. However, in
order to maintain such compliance, it is equally important to implement the following precautions when a set
is being serviced
Precautions during Servicing
Parts identified by the # symbol are critical for
A.
safety. Replace only with part number specified.
In addition to safety, other parts and assemblies
B.
are specified for conformance with regulations
applying to spurious radiation. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.
Use specified internal wiring. Note especially:
C.
1)Wires covered with PVC tubing
2)Double insulated wires
3)High voltage leads
Use specified insulating materials for hazardous
D.
live parts. Note especially:
1)Insulation tape
2)PVC tubing
3)Spacers
4)Insulators for transistors
When replacing AC primary side components
E.
(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before soldering.
Observe that the wires do not contact heat produc-
F.
ing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.).
Check that replaced wires do not contact sharp
G.
edges or pointed parts.
When a power cord has been replaced, check that
H.
5 - 6 kg of force in any direction will not loosen it.
.
Also check areas surrounding repaired locations.
I.
Be careful that foreign objects (screws, solder
J.
droplets, etc.) do not remain inside the set.
Crimp type wire connector
K.
The power transformer uses crimp type connectors
which connect the power cord and the primary side
of the transformer. When replacing the transformer,
follow these steps carefully and precisely to prevent shock hazards.
Replacement procedure
1)Remove the old connector by cutting the wires at a
point close to the connector.
Important:
2)Strip about 15 mm of the insulation from the ends
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 a crimping tool to crimp the metal sleeve at its
center. Be sure to crimp fully to the complete closure of the tool.
When connecting or disconnecting the internal con-
L.
nectors, first, disconnect the AC plug from the AC
outlet.
Do not re-use a connector. (Discard it.)
1-3-1 DVD_SFN1
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 their original positions. Afterwards, do the following tests and confirm
the specified values to verify compliance with safety
standards.
1. Clearance Distance
When replacing primary circuit components, confirm
specified clearance distance (d) and (d’) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)

Note:
Be sure to confirm the precise values.
2. Leakage Current Test
Confirm the specified (or lower) leakage current
between B (earth ground, power cord plug prongs)
and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and
output terminals, microphone jacks, earphone jacks,
etc.) is lower than or equal to the specified value in the
table below.
Measuring Method (Power ON) :
Insert load Z between B (earth ground, power cord
plug prongs) and exposed accessible parts. Use an
AC voltmeter to measure across the terminals of load

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is properly grounded to remove any static electricity that may
be charged on the body.
2. Ground for Workbench
(4) Be sure to place a conductive sheet or copper plate
with proper grounding (1MΩ) on the workbench or
other surface, where the semi-conductors are to be
placed. Because the static electricity charge on
clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.
