SAFETY PRECAUTIONS
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in
the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to
prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
General Guidance
An lsolation 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 circuitary that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace
it with the specified.
When replacing a high wattage resistor (Oxide Metal Film
Resistor, over 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to high vacuum and large surface area of picture tube,
extreme care should be used in handling the Picture Tube.
Do not lift the Picture tube by it's Neck.
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 positioin, 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 1MΩ and 5.2MΩ.
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 1.5K/10watt resistor in parallel with a 0.15uF 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 esposed metallic part. Any
voltage measured must not exceed 0.75 volt RMS which is
corresponds to 0.5mA.
In case any measurement is out of the limits sepcified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.

GROUNDING
Ensure that you connect the grounding / earth wire to prevent possible
electric shock. If grounding methods are not possible, have a qualified
electrician install a separate circuit breaker. Do not try to ground the
unit by connecting it to telephone wires, lightening rods, or gas pipes.
For proper ventilation, allow a clearance of 4” on each
side and 2” from the wall. Detailed installation instruc-
tions are included from your dealer in the optional Wall
Mounting Bracket Installation and Setup Guide.

1. Application Object
These instructions are applied to all of the PDP monitor/TV
with Tuner Box, RF-03GA.
2. Notes
(1) Because this is not a hot chassis, it is not necessary to use
an isolation transformer. However, the use of isolation
transformer will help protect test instruments.
(2) Adjustments must be performed in the correct order.
(3) The adjustments must be performed in conditions between
68° and 86°F with 55-75% relative humidity.
(4) The input voltage of the receiver must keep at 100~240V,
50/60Hz during adjustment(s).
(5) The receiver must be operated for at least 15 minutes prior
to the adjustment(s).
1) The receiver must be operated receiving 100% white
pattern, prior to adjustment(s).
(White condition in HEAT-RUN mode)
2) Enter into HEAT-RUN mode
- Press the POWER ON KEY on Adjustment R/C.
- OSD display HEAT-RUN WHITE and screen display
100% full WHITE PATTERN.
[Set is activated HEAT-RUN without signal generator in
this mode.
[Single color pattern of HEAT-RUN mode uses to check
PANEL. (RED/BLUE/GREEN)
[Caution] If you turn on a still screen more than 20 minutes
(such as Cross Hatch Pattern, Digital Pattern), an
afterimage may be occur in the black level part of the
screen. (Image Burn)
O Data values, adjusted in the board, are valid until the VSC
Board is dissued and must be protected. For the protection of
data, Micom does not permit any more adjustments after
completion.
O In case of re-adjustment, operate First Value Setting.
Each PCB Assy must be checked prior to installation.
(Especially, be careful Power PCB Assy which can cause
damage to PDP Module.)
3. POWER PCB Assy Voltage
Adjustments (Va, Vs Voltage Adjustments)
3-1 Test Equipment :Digital Multi-Meter (DMM)
3-2 Connection Diagram for Measuring
Refer to Fig 1.
3-3 Adjustment Method
(1) Va Adjustment
1) Select White Mode of HEAT RUN or receive a 100%
Full White Pattern with the Video/RGB from a Pattern
Generator.
2) Connect the + terminal of the DMM to Va pin of P805
and the - terminal of the DMM to GND pin of P805.
3) Adjust RV601 until the reading of Va on the DMM is the
same as Va voltage on label of panel Right/Top.
(Deviation : ±0.5V)
(2) Vs adjustment
1) Connect the + terminal of the DMM to Vs pin of P805
and the - terminal of the DMM to GND pin of P805.
2) Adjust RV401 until the reading of Vs on the DMM is the
same as Vs voltage on label of panel Right/Top.
(Deviation : ±0.5V)
4. Auto ADC Adjustments
4-1 RGB Auto Offset & Gain Adjustment
(1) Input Half Black/White (255 Gray) signal from a Pattern
Generator into the RGB Input.

(2) Press POWER ON KEY on the Adjustment R/C and select
RGB Cut.
(3) Press Vol. + key and operate TO SET(Black).
(4) Original Half Black/White(255 Gray) screen will be
presented about 5~10 seconds later. And Cursor moves
with a lower part Y-cut.
This case RGB Auto Offset, MAX Gain adjustment will be
completed.
4-2 Component Auto Offset & Gain
Adjustment (Y, Pb, Pr Adjustment)
(1) Input Half Black/White (255 Gray) signal from a Pattern
Generator into the component Input. (1280*720p 60Hz)
(2) Press Vol. + key and operate To SET from the condition
where the cursor moves with the Y-cut.
(3) Original Half White(255 Gray) screen will be presented
about 5~10 seconds later. And Cursor moves with a lower
part Pb-cut.
This case Component Y-offset & Gain adjustment will be
completed.
(4) After adjustment of item (3), receive Half Blue(127 level)
signal for Pb-offset adjustment.
(5) Press Vol. + key and operate To SET for Pb-offset
adjustment.
(6) Original Half Blue(127 level) screen will be presented
about 5~10 seconds later. And Cursor moves with a lower
part Pr-cut.
This case Component Pb-offset & Gain adjustment will be
completed.
(7) After adjustment of item (5), receive Half Red(127 level)
signal for Pr-offset adjustment.
(8) Press Vol. + key and operate To SET for Pr-offset
adjustment.
(9) Original Half Red(127 level) screen will be presented
about 5~10 seconds later and the OK indication appears.
This case Component Auto offset & Gain adjustment will
be completed.
O You can check whether circuit adjustment is correct or not,
below. (Item 4-1)
(1) Display RGB to the Main picture, CVBS to the Sub picture
in TWIN PICTURE mode. (DOUBLE WINDOW)
(2) To check the Offset, input Full Black (0 gray) signal into
CVBS and RGB input part at the same time in the Pattern
Generator.
(3) To check the MAX-Gain, input Full White (255 gray) signal
into CVBS and RGB input part at the same time in the
Pattern Generator.
(4) Visually compare Black and White Levels. If there is no
Level difference, then the adjustment is correct.
O You can check whether circuit adjustment is correct or not,
below. (Item 4-2)
(1) Display Component to the Main picture, CVBS to the Sub
picture in TWIN PICTURE mode. (DOUBLE WINDOW)
