Please heed the points listed below during servicing and inspection.
◎Heed the cautions!
Spots requiring particular attention when servicing, such as
the cabinet, parts, chassis, etc., have cautions indicated on
labels or seals. Be sure to heed these cautions and the cau-
tions indicated in the handling instructions.
◎Caution concerning electric shock!
(1) An AC voltage is impressed on this set, so touching inter-
nal metal parts when the set is energized could cause
electric shock. Take care to avoid electric shock, by for ex-
ample using an isolating transformer and gloves when
servicing while the set is energized, unplugging the power
cord when replacing parts, etc.
(2)There are high voltage parts inside. Handle with extra care
when the set is energized.
◎ Caution concerning disassembly and assembly!
Though great care is taken when manufacturing parts from
sheet metal, there may in some rare cases be burrs on the
edges of parts which could cause injury if fingers are moved
across them. Use gloves to protect your hands.
◎Only use designated parts!
The set\'s parts have specific safety properties (fire resis-
tance, voltage resistance, etc.). For replacement parts, be
sure to use parts which have the same properties. In particu-
lar, for the important safety parts that are marked   !   on wiring
diagrams and parts lists, be sure to use the designated parts.
◎Be sure to mount parts and arrange the
wires as they were originally!
For safety reasons, some parts use tape, tubes or other insu-
lating materials, and some parts are mounted away from the
surface of printed circuit boards. Care is also taken with the
positions of the wires inside and clamps are used to keep
wires away from heating and high voltage parts, so be sure to
set everything back as it was originally.
◎ Inspect for safety after servicing!
Check that all screws, parts and wires removed or discon-
nected for servicing have been put back in their original posi-
tions, inspect that no parts around the area that has been
serviced have been negatively affected, conduct an insulation
check on the external metal connectors and between the
blades of the power plug, and otherwise check that safety is
ensured.
(Insulation check procedure)
Unplug the power cord from the power outlet, disconnect the
antenna, plugs, etc., and turn the power switch on. Using a
500V insulation resistance tester, check that the insulation re-
sistance between the terminals of the power plug and the ex-
ternally exposed metal parts (antenna terminal, headphones
terminal, microphone terminal, input terminal, etc.) is 1MΩ or
greater. If it is less, the set must be inspected and repaired.
Concerning important safety parts
Many of the electric and structural parts used in the set have
special safety properties. In most cases these properties are
difficult to distinguish by sight, and using replacement parts
with higher ratings (rated power and withstand voltage) does
not necessarily guarantee that safety performance will be pre-
served. Parts with safety properties are indicated as shown
below on the wiring diagrams and parts lists is this service
manual. Be sure to replace them with parts with the designat-
ed part number.
(1) Schematic diagrams ... Indicated by the   !   mark.
(2) Parts lists ... Indicated by the   !   mark.
Using parts other than the designated parts
could result in electric shock, fires or other
dangerous situations.
SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power
cord is less than 460 kohms, the unit is defective.
LASER RADIATION
Do not stare into beam or view directly with optical instruments, class 3A laser product.

being held by glue. When the flat pack-IC is
removed from the CBA, handle it gently
because it may be damaged if force is applied.
2. Installation
1.
Using desoldering braid, remove the solder from
the foil of each pin of the flat pack-IC on the CBA
so you can install a replacement flat pack-IC more
easily.
2.
The “●” mark on the flat pack-IC indicates pin 1.
(See Fig. S-1-7.) Be sure this mark matches the 1
on the PCB when positioning for installation. Then
presolder the four corners of the flat pack-IC. (See
Fig. S-1-8.)

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 (1 MΩ) 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 (1 MΩ) 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.

CAUTION 2: Electrostatic breakdown of the laser 
diode in the optical system block may occur as a 
potential difference caused by electrostatic charge 
accumulated on cloth, human body etc., during 
unpacking or repair work.
To avoid damage of pickup follow next procedures.
1) Short the three short lands of FPC cable with 
solder before removing the FFC cable (CN201) 
from it. If you disconnect the FFC cable 
(CN201), the laser diode of pickup will be 
destroyed. (Fig. D5)

Power Supply Block Diagram
CAUTION !
Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown , 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.
NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
CAUTION !
For continued protection against fire hazard,
replace only with the same type fuse.

SCHEMATIC DIAGRAMS / CBA’S AND TEST POINTS
Standard Notes
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.
Notes:
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 = 103, M = 106).
3.
Resistor wattages are 1/4W or 1/6W unless 
otherwise specified.
4.
All capacitance values are indicated in µF
(P = 10-6 µF).
5.
All voltages are DC voltages unless otherwise 
specified.
6.
Electrical parts such as capacitors, connectors, 
diodes, IC’s, transistors, resistors, switches, and 
fuses are identified by four digits. The first two 
digits are not shown for each component. In each 
block of the diagram, there is a note such as 
shown below to indicate these abbreviated two 
digits.

AV 1/3 Schematic Diagram
CAUTION !
Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown , 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.
NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
CAUTION !
For continued protection against fire hazard,
replace only with the same type fuse.
