SAFETY PRECAUTIONS
The following items should be checked for continued protection of the customer and the service technician.
Leakage current check
Before returning the set to the customer, be sure to carry out 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 set is defective.
Be sure to test for leakage current with the AC plug in both polarities, in addition, when the set's power is in each state (on, off and standby mode), if applicable.
Before Servicing
This Unit
CAUTION
Please heed the following cautions and instructions during servic-
ing and inspection.
◎ Heed the cautions!
Cautions which are delicate in particular for servicing are labeled on the cabinets, the parts and the
chassis, etc. Be sure to heed these cautions and the cautions described in the handling instructions.
◎ Cautions concerning electric shock!
(1) An AC voltage is impressed on this set, so if you touch internal metal parts when the set is energized,
you may get an electric shock. Avoid getting an electric shock, by using an isolating transformer and
wearing gloves when servicing while the set is energized, or by unplugging the power cord when
replacing parts, for example.
(2) There are high voltage parts inside. Handle with extra care when the set is energized.
◎ Caution concerning disassembly and assembly!
Through great care is taken when parts were manufactured from sheet metal, there may be burrs on the
edges of parts. The burrs could cause injury if ngers are moved across them in some rare cases. Wear
gloves to protect your hands.
◎ Use only designated parts!
The set's parts have specic safety properties (re resistance, voltage resistance, etc.). Be sure to use
parts which have the same properties for replacement. The burrs have the same properties. In particular,
for the important safety parts that are indicated by the z mark on schematic diagrams and parts lists,
be sure to use the designated parts.
◎ Be sure to mount parts and arrange the wires as they were originally placed!
For safety seasons, some parts use tapes, tubes or other insulating materials, and some parts are mounted away from the surface of printed circuit boards. Care should also be taken with the positions of the
wires by arranging them and using clamps to keep them away from heating and high voltage parts, so
be sure to set everything back as it was originally placed.
◎ Make a safety check after servicing!
Check that all screws, parts and wires removed or disconnected when servicing have been put back
in their original positions, check that no serviced parts have deteriorated the area around. Then make
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 on the power.
Using a 500V insulation resistance tester, check that the insulation resistance value between the inplug
and the externally exposed metal parts (antenna terminal, headphones terminal, input terminal, etc.) is
1M Ω or greater. If it is less, the set must be inspected and repaired.
CAUTION
Many of the electric and the structural parts used in the set have special safety properties. In most cases
these properties are difcult to distinguish by sight, and the use of replacement parts with higher ratings (rated power and withstand voltage) does not necessarily guarantee that safety performance will
be preserved. Parts with safety properties are indicated as shown below on the wiring diagrams and the
parts list in this service manual. Be sure to replace them with the parts which have the designated part
number.
(1) Schematic diagrams Indicated by the z mark.
(2) Parts lists Indicated by the z mark.
The use of parts other than the designated parts could cause electric shocks, res or other dangerous
situations.

NOTE FOR SCHEMATIC DIAGRAM
WARNING:
Parts indicated by the z mark have critical characteristics. Use ONLY replacement parts recommended
by the manufacturer.
CAUTION:
Before returning the set to the customer, be sure to carry out 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 set is defective.
WARNING:
DO NOT return the set to the customer unless the problem is identied and remedied.

NOTICE:
(1) ALL RESISTANCE VALUES IN OHM. k=1,000 OHM / M=1,000,000 OHM
(2) ALL CAPACITANCE VALUES ARE EXPRESSED IN MICRO FARAD, UNLESS OTHERWISE INDICATED. P

(3) EACH VOLTAGE AND CURRENT ARE MEASURED AT NO SIGNAL INPUT CONDITION.
(4) CIRCUIT AND PARTS ARE SUBJECT TO CHANGE WITHOUT PRIOR NOTICE.
HANDLING THE SEMICONDUCTOR AND OPTICS
Electrostatic breakdown of the semi-conductors or optical pickup 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 M ohm) 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 M ohm) 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

TROUBLE SHOOTING
1. POWER
1.1. The unit does not power on
1.2. Fuse is blown
Before Servicing
This Unit
The unit does not power on
Does the power indicator on the front panel ash
in green or white when the power is turned on?
YES
YES
Is a fuse blown?
NO
See "1.2. Fuse is blown"
Is DC 5.2V being supplied from the SMPS PCB
[BN601] to the DIGITAL PCB?
YESYES
Check the circuits around the Microprocessor on the DIGITAL PCB and replace any faulty
parts.
Does the power display on the front panel lights
green or white after approximately 8 seconds?
NO
YES
Does the power shut down after several seconds?
NO
TO "6. SMPS"
NO
NO
Is DC 5.2V output even when the Board in wire
[BN601] supplying power from the SMPS PCB to
the DIGITAL PCB is removed?
Check for breakages and short circuits in the circuits and parts between [CN741] on the DIGITAL
PCB and the microprocessor power supply and
replace any faulty parts.
YESNO
Are there any parts not fully connected into the
connectors that connect the PCBs?
Check for leaks and short circuits
in the parts on the primary side.
Replace any faulty parts.
TO "3-2. Protection History
Display Mode"
Blown fuse
Check the rectier diode in the
rectier circuit on the secondary
side, and check for short circuits.
Replace any faulty parts.
Replace the fuse after repair.
Check for short circuits between the
regulator output terminal and GND
in the power supply stabilization
circuit. Replace faulty parts if there
is a short circuit.
ElectricalMechanicalRepair InformationUpdating
NOYES
YES
Is a fuse blown?Connect the connectors correctly.
NO
