WARNING
• Always advise users to keep children away.
There is danger of injury to children from tools, disassembled products, etc.
• Always disconnect the power plug before starting work whenever power is not required.
Failure to disconnect the power plug before starting work can result in electrical shock.
• Depending on the model, use an insulation transformer or wear gloves when servicing with the
power on, and disconnect the power plug to avoid electrical shock when replacing parts.
In some cases, alternating current is also impressed in the chassis, so electrical shock is possible if the chassis is contacted with the power on.
• Always use the replacement parts specified for the particular model when making repairs.
The parts used in products have the necessary safety characteristics such as inflammability,
voltage resistance, etc.; therefore, use only replacement parts that have these same characteristics.
Use only the specified parts when the
• Parts mounting and routing of the wiring should be the same as that used originally.
For safety purposes, insulating materials such as tubing or tape is sometimes used and printed
circuit boards are sometimes mounted floating.
Also make sure that wiring is routed and clamped to avoid parts that generate heat and which
use high voltage. Always follow the original scheme.
• After a repair has been completed, reassemble all disassembled parts, and route and reconnect the wiring, in accordance with the original scheme.
Do not allow internal wiring to be pinched by cabinets, panels, etc.
Any error in reassembly or wiring can result in electrical leakage, flame, etc., and may be
hazardous.
mark is included in a circuit diagram or parts list.
CHECK INSULATION
RESISTANCE
PROHIBIT
REMODELING
• After completing the work, disconnect the power plug from the outlet, remove the antenna, turn
on the power switch. Then, use a 500V insulation resistance meter to check the insulation
resistance of the antenna terminal, other metallic parts and between the prongs of the power
plug to make sure that the insulation resistance is 1M 1 or more.
The set will require inspection and repair if the insulation resistance is below this value.
• Never remodel the product in any way.
Remodeling can result in improper operation, malfunction, or electrical leakage and flame,
which may be hazardous

GENERALADJUSTMENTSSPECIFICINFORMATIONS
HANDLING THE LCD MODULE
Safety Precautions
In the event that the screen is damaged or the liquid crystal
(fluid) leaks, do not breathe in or drink this fluid. Also, never
touch this fluid.
Such actions could cause toxicity or skin irritation. If this fluid
should enter the mouth, rinse the mouth thoroughly with water. If the fluid should contact the skin or clothing, wipe off
with alcohol, etc., and rinse thoroughly with water. If the fluid
should enter the eyes, immediately rinse the eyes thoroughly
with running water.
Precautions for Handling the LCD Module
The LCD module can easily be damaged during disassembly
or reassembly; therefore, always observe the following precautions when handling the module.
1. When attaching the LCD module to the LCD cover, position it appropriately and fasten at the position where the
display can be viewed most conveniently.
3. If the panel surface becomes soiled, wipe with cotton or a
soft cloth. If this does not remove the soiling, breathe on
the surface and then wipe again.
If the panel surface is extremely solied, use a CRT cleaner
as a cleaner. Wipe off the panel surface by drop the cleaner
on the cloth. Do not drop the cleaner on the panel. Pay
attention not to scratch the panel surface.
4. Leaving water or other fluids on the panel screen for an
extended period of time can result in discoloration or
stripes. Immediately remove any type of fluid from the
screen.
2. Carefully align the holes at all four corners of the LCD
module with the corresponding holes in the LCD cover
and fasten with screws. Do not strongly push on the module because any impact can adversely affect the performance. Also use caution when handling the polarized screen
because it can easily be damaged.
The metal edges of the LCD module
CAUTION
are sharp, so use caution to avoid injury.
5. Glass is used in the panel, so do not drop or strike with
hard objects. Such actions can damage the panel.
6. CMOS-LSI circuitry is used in the LCD module, so avoid
damage due to static electricity. When handling the module, use a wrist ground or anchor ground.
-

-
7. Do not expose the LCD module to direct sunlight or strong
ultraviolet rays for an extended period of time.
8. Do not store the LCD module below the temperature conditions described in the specifications. Failure to do so
could result in freezing of the liquid crystal due to cold air
or loss of resilience or other damage.
9. Do not disassemble the LCD module. Such actions could
result in improper operation.
10. When transporting the LCD module, do not use packing
containing epoxy resin (amine) or silicon resin (alcohol or
oxim). The gas generated by these materials can cause
loss of polarity.

WARNING: BEFORE SERVICING THIS CHASSIS, READ THE “SERVICE SAFETY PRECAUTIONS” ON PAGE 3 OF THIS
MANUAL.
CAUTION: The international hazard symbols "" in the schematic diagram and the parts list designate components which
have special characteristics important for safety and should be replaced only with types identical to those in the original
circuit or specified in the parts list. The mounting position of replacements is to be identical with originals. Before replacing
any of these components, read carefully the SERVICE SAFETY PRECAUTIONS. Do not degrade the safety of the receiver
through improper servicing.
NOTICE:
•
The part number must be used when ordering parts, in order to assist in processing, be sure to include the Model
number and Description.

SCHEMATIC DIAGRAM
MODEL : 32HL85
WARNING : BEFORE SERVICING THIS CHASSIS, READ THE "SERVICE SAFETY PRECAUTIONS" ON PAGE 3 OF
THIS MANUAL.
CAUTION : The international hazard symbols " " in the schematic diagram and the parts list designate components
which have special characteristics important for safety and should be replaced only with types identical to those in the
original circuit or specified in the parts list. The mounting position of replacements is to be identical with originals. Before
replacing any of these components, read carefully the SERVICE SAFETY PRECAUTIONS on the MANUAL for this
model. Do not degrade the safety of the receiver through improper servicing.
NOTE:
1. RESISTORResistance is shown in ohm [K = 1.000, M = 1.000.000]. All resistors are 1/6W and 5%
tolerance carbon resistor, unless otherwise noted as the following marks.
1/2R = Metal or Metal oxide of 1/2 watt1/2S = Carbon compsistion of 1/2 watt
1RF = Fuse resistor of 1 watt10W = Cement of 10 watt
K = ±10% G = ±2% F = ± 1%
2. CAPACITOR Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in
?F, and the values more than 1 in pF.
All capacitors are ceramic 50V, unless otherwise noted as the following marks.
Electolytic capacitorMylar capacitor
3. The parts indicated with " * " have special characteristics, and should be replaced with identical parts only.
4. Voltages read with DIGITAL MULTI-METER from point indicated to chassing ground, using a color bar signal with all
controls at normal, line voltage 220 volts.
5. Waveforms are taken receiving color bar signal with enough sensitivity.
6. Voltage reading shown are nominal values and may vary ±20% except H.V.
