Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the
Schematic Diagram and Exploded View.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent
Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
General Guidance
An isolation Transformer should always be used during the
servicing of a receiver whose chassis is not isolated from the AC
power line. Use a transformer of adequate power rating as this
protects the technician from accidents resulting in personal injury
from electrical shocks.
It will also protect the receiver and it's components from being
damaged by accidental shorts of the circuitry that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this TV receiver is blown,
replace it with the specified.
When replacing a high wattage resistor (Oxide Metal Film Resistor,
over 1 W), keep the resistor 10 mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Before returning the receiver to the customer,
always perform an AC leakage current check on the exposed
metallic parts of the cabinet, such as antennas, terminals, etc., to
be sure the set is safe to operate without damage of electrical
shock.
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source, connect an
electrical jumper across the two AC plug prongs. Place the AC
switch in the on position, connect one lead of ohm-meter to the AC
plug prongs tied together and touch other ohm-meter lead in turn to
each exposed metallic parts such as antenna terminals, phone
jacks, etc.
If the exposed metallic part has a return path to the chassis, the
measured resistance should be between 1 MΩand 5.2 MΩ.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before the
receiver is returned to the customer.
Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5 K / 10 watt resistor in parallel with a 0.15 uF capacitor
between a known good earth ground (Water Pipe, Conduit, etc.)
and the exposed metallic parts.
Measure the AC voltage across the resistor using AC voltmeter
with 1000 ohms/volt or more sensitivity.
Reverse plug the AC cord into the AC outlet and repeat AC voltage
measurements for each exposed metallic part. Any voltage
measured must not exceed 0.75 volt RMS which is corresponds to
0.5 mA.
In case any measurement is out of the limits specified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.

4.2. Adjustment order
(refer to the Adjustment standard and adjustment command
table)
4.2.1. Board Assembly Line
■ Connect input signal to 15pin D-sub.
■ Ready for adjustment: check whether adjustment command
works normally or not and the operating state of each mode.
■ Check the display state of gray color when 256 gray scale
pattern is embodied.
■ Read by EEPROM Read Command to check whether initial
value is correct or not.
4.2.2. Total Assembly Line

■ If error is occurred, write and check again.
■ Ready : Warm-up in 5 minutes in the state with
signal(depends on line condition)
■ Connect input signal to D-sub.
■ Default value before adjustment : Contrast “70” , Brightness
“100(Max)”

position, Clock and Phase at each Mode.
■ There is no special factory mode adjustment.
Writing initial value of EEPROM in Board Assembly line is
adjusting Preset Mode and Reset mode. (EEPROM is
initialized when AC Power is ON first.)
■ If the change of FOS data is needed after M.P, it is possible
by writing Mode Data with EEPROM write command or
modifying the Mode Data in MICOM itself.

address of EEPROM(0xA6) is not 0xAA, do adjust again
■ If all Adjustment is completed, the values of 6500K, User
Color and 9300K are saved automatically.
4.2.4.3. Confirm at Total Assembly Line: adjustment
■ Check the data of 0XFD, 0XFE address of EEPROM(0xA6)

change) whether module name and aging time
disappeared on the self-diagnostics OSD with signal cable
disconnected.
-> If Elapsed Time Clear command isn’t executed, module
name, aging time and TCO word appear on the self-
diagnostics OSD.(Module name and aging time should not
appear after writing EDID)
