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.
: Nominal specs represent the design specs. All units should be able to approximate these – some will exceed
Note
and some may drop slightly below these specs. Limit specs represent the absolute worst condition that still might
be considered acceptable; In no case should a unit fail to meet limit specs.

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.)

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)
Table 1 : Ratings for selected area
AC Line VoltageClearance Distance (d) (d’)
120 V
This table is unofficial and for reference only.
Note:
Be sure to confirm the precise values.
≥ 3.2 mm (0.126 inches)
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
Z. See Fig. 2 and the following table.

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
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.

Power Supply Trouble Shooting Guide
It is highly recommended that a variable isolation
transformer which can monitor current be used.
(Alternatively a variable AC source which monitors current will do). Read directions below before
power is added!
Repair method
CHECK
Connect unit to the isolation transformer and slowly increase the AC supply while monitoring the current, if it
draws too much current (Be ware fuse
is rated for 1.0 amps), then turn off
supply and do repair method #1.
NO
Check whether the primary rectifying
DC of the Switching power supply has
an output. (Reading should be about
168V.)
YES
With the primary DC working check
the secondary 5V.
YES
Are the 40V, 12V, -30V, 5V and
filaments lines higher than normal?
NO
Although the secondary 5V is working,
are any of the other voltages higher
than normal (40V, 12V, -30V and
filament voltages)?
NO
There is no problem on the SW power
supply.
YES
NO
NO
YES
YES
#1
#2
#3
#4
#5
Repair method #1
(Power must be off)
Short circuit in the secondary side. check diode D013
and {(FIP display model only: D012, D015, D016 and
D017) or (LED display model only: D014, D015 and
D016)}, switching FET (Q001), control transistor
(Q002), diode (D006), and resistor (R014) replace as
necessary.
Disconnect 40V diode (D013), 12V diode (D015), 5V
diode (D016) and {FIP display model only: -30V diode
(D012) and filament voltage diode (D017)}Check the
load continuity of 40V line, 12V line, 5V line, -30V line
and filament voltage line through a tester (resistance
range).
If the tester indicates a lower resistance value around
0 ohm, the line is short-circuited.
Before repairing the switching power supply, find out
the short-circuited area of such line and repair it.
If the tester does not indicate any low resistance value
(around 0 ohm), no load is short-circuited and there is
no problem.
2] Check for any defective parts while the secondary
rectifying diodes are disconnected (D013, D015, D016
and {FIP display model only: D012 and D017)} perform a diode check in both forward and reverse directions through a tester.
3] Remove the following components and check for
defects: snubber diode (D051), switching FET (Q001),
source resistor (R014), control transistor (Q002).
Repair method #2
Check the fuse 1.0A (F001), primary rectifying diodes
(D001-D004) as possible problems. Remove the
above mentioned parts and check them. The circuit
which turns on switching FET (Q001) may be
regarded as a possible cause, even if the load at the
secondary side is shorted, it can't be detected
because switching FET (Q001) isn't operating. Perform check according to the step 1 and 2 of repair
method #1 and check the following parts:
(Remove the part from PCB)
Switching FET (Q001), source resistor (R014), gate
resistor (R008) and start resistor (R004 and R005).
Repair method #3
A circuit to turn on switching FET (Q001) may not work
and this may be regarded as a cause of trouble. Even
if the load at the secondary side is short-circuited, it
cannot be detected because switching FET (Q001)
does not turn on. Therefore, perform check according
to the steps 1] and 2] of the repair method #1 and execute the under-mentioned parts breakage check.
(Remove the part from PCB.)
switching FET (Q001), source resistor (R014), control
transistor (Q002), gate resistor (R008) and start resistor (R004 and R005).
Repair method #4
The feedback circuit which is monitored by the output
of voltage may not work and this may be regarded as
a possible cause, remove control transistor Q002 and
check for defects. More over, a photo coupler (IC001)
and transistor (Q031) may be defective, replace any
defective parts with factory originals.
Repair method #5
If the output voltage of the secondary side is slightly
high, the line load may be in the "OPEN" state and this
may be regarded as a cause of trouble. If there is no
output voltage on the secondary side, the rectifying
diodes (D013), (D015) and {FIP display model only
only: (D012) and (D017)} may be defective.

WARNING
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.

1-A. Preliminary/Final Checking and
Alignment of Tape Path
Purpose:
To make sure that the tape path is well stabilized.
Symptom of Misalignment:
If the tape path is unstable, the tape will be damaged.
Do not use an Alignment Tape for this proce-
Note:
dure. If the unit is not correctly aligned, the tape may
be damaged.
1. Play back a blank cassette tape and check to see
that the tape runs without creasing at Guide Rollers
[2] and [3], and at points A and B on the lead surface. (Refer to Fig M3 and M4.)
2. If creasing is apparent, align the height of the guide
rollers by turning the top of Guide Rollers [2] and
[3] with a Guide Roller Adj. Screwdriver. (Refer to
Fig. M3 and M5.)

1-B. X Value Alignment
Purpose:
To align the Horizontal Position of the Audio/Control/
Erase Head.
Symptom of Misalignment:
If the Horizontal Position of the Audio/Control/Erase
Head is not properly aligned, maximum envelope cannot be obtained at the Neutral position of the Tracking
Control Circuit.
1. Connect the oscilloscope to TP301 (C-PB) and
TP303 (CTL) on the Main CBA. Use TP302 (RFSW) as a trigger.
2. Play back the Gray Scale of the Alignment Tape
(FL8NW) and confirm that the PB FM signal is
present.
3. Set the Tracking Control Circuit to the center position by pressing CH UP button then “ PLAY ” button
on the unit. (Refer to note on bottom of page
2-3-4.)
4. Use the X-Value Adj. Screwdriver so that the PB
FM signal at TP301 (C-PB) is maximum. (Fig. M6)
5. Press CH UP button on the unit until the CTL waveform has shifted by approx. +2msec. Make sure
that the envelope is simply attenuated (shrinks in
height) during this process so that you will know
the envelope has been at its peak.

Page 53
6. Press CH DOWN button on the unit until the CTL
waveform has shifted from its original position (not
the position achieved in step 5, but the position of
CTL waveform in step 4) by approximately -2msec.
Make sure that the envelope is simply attenuated
(shrinks in height) once CTL waveform passes its
original position and is further brought in the minus
direction.
7. Set the Tracking Control Circuit to the center position by pressing CH UP button and then “ PLAY ”
button.
1-C. Checking/Adjustment of Envelope
Waveform
Purpose:
To achieve a satisfactory picture and precise tracking.
Symptom of Misalignment:
If the envelope output is poor, noise will appear in the
picture. The tracking will then lose precision and the
playback picture will be distorted by any slight variation of the Tracking Control Circuit.
1. Connect the oscilloscope to TP301 (C-PB) on the
Main CBA. Use TP302 (RF-SW) as a trigger.
2. Play back the Gray Scale on the Alignment Tape
(FL8NW). Set the Tracking Control Circuit to the
center position by pressing CH UP button and then
“ PLAY ” button on the unit. Adjust the height of
Guide Rollers [2] and [3] (Fig. M3, Page 2-3-3)
watching the oscilloscope display so that the envelope becomes as flat as possible. To do this adjustment, turn the top of the Guide Roller with the
Guide Roller Adj. Screwdriver.
3. If the envelope is as shown in Fig. M7, adjust the
height of Guide Roller [2] (Refer to Fig. M3) so that
the waveform looks like the one shown in Fig. M9.
4. If the envelope is as shown in Fig. M8, adjust the
height of Guide Roller [3] (Refer to Fig. M3) so that
the waveform looks like the one shown in Fig. M9.
5. When Guide Rollers [2] and [3] (Refer to Fig.M3)
are aligned properly, there is no envelope drop
either at the beginning or end of track as shown in
Fig. M9.
Note: Upon completion of the adjustment of Guide
Rollers [2] and [3] (Refer to Fig. M3), check the X
Value by pushing the CH UP or DOWN buttons alternately, to check the symmetry of the envelope. Check
the number of pushes to ensure center position. The
number of pushes CH UP button to achieve 1/2 level
of envelope should match the number of pushes CH
DOWN button from center. If required, redo the “X
Value Alignment.”
1-D. Azimuth Alignment of Audio/Control/
Erase Head
Purpose:
To correct the Azimuth alignment so that the Audio/
Control/Erase Head meets tape tracks properly.
Symptom of Misalignment:
If the position of the Audio/Control/Erase Head is not
properly aligned, the Audio S/N Ratio or Frequency
Response will be poor.
1. Connect the oscilloscope to the audio output jack
on the rear side of the deck.
2. Play back the alignment tape (FL8NW) and confirm
that the audio signal output level is 8kHz.
3. Adjust Azimuth Adj. Screw so that the output level
on the AC Voltmeter or the waveform on the oscilloscope is at maximum. (Fig. M6)

ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align the
individual gears and levers that make up the tape
loading/unloading mechanism. Since information
about the state of the mechanism is provided to the
System Control Circuit only through the Mode Switch,
it is essential that the correct relationship between
individual gears and levers be maintained.
All alignments are to be performed with the mechanism in Eject mode, in the sequence given. Each
procedure assumes that all previous procedures have
been completed.
IMPORTANT:
If any one of these alignments is not performed
properly, even if off by only one tooth, the unit will
unload or stop and it may result in damage to the
mechanical or electrical parts.
