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 usedduring 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 checkon 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.

Apply to 27” /23.8” wide monitor made in Monitor Factory(Kumi Korea) or made in accordance with the standard
of Kumi Factory process.
2. Appointment
2.1 Adjustment must be done as fixed sequence, and adjustment sequence can be modified after agreement with
the responsible R&D engineer considering mass-production condition.
2.2 Power : AC100~240 Voltage (Free)
2.3 Input signal : As Product Standard(Signal ROM : 24MB35PY/23MB35PY/22MB35Y)
2.4 WARM(6500K)-up Time : Over than 5 minutes
2.5 Adjustment equipment : White balance equipment (CA-110/210), Display adjust equipment, VG-819(or VG828),
Oscilloscope, PC (More than 486 computer ) & White balance adjust program.,
HDCP Adjusting Jig equipment.
3. Adjustment
3.1 Overview
Use factory automation equipment and adjust automatic movement. But, do via passivity adjust in error
occurrence.
3.2 Adjustment order(refer to the Adjustment standard and adjustment command table)
3.2.1 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.
3.2.2 Total Assembly Line
Input analog signal. (1920X1080@60Hz)
Write HDCP Key to EEPROM(24C16) by using DDC2AB protocol &HDCP Adjusting Jig
equipment [ Address 0xAC 80, 289 bytes ]
If error is occurred, write and check again.
Ready : Heat-run during 30 minutes in the state with signal
Connect input signal to D-sub.
Default value before adjustment : Contrast “70” , Brightness “100(Max)”
3.2.3 Adjustment of Horizontal/Verticality screen position, Clock and Clock 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.
