1. For Safe Service

1-1. SAFETY PRECAUTIONS

MIS-4201 is a display device to be divided into a Panel part , a Drive part and a
mechanical part. The Panel part consists of Electrodes, Phosphor, various dielectrics and
gas, the Drive part includes electronic circuitry and Board and The mechanical part
includes mask assembly, back cover and other parts.
When using / handling this monitor, Please pay attention to the below warning and cautions.
Indicates a hazard that may lead to death or injury if the warning is ignored and the
product is handled incorrectly.
Indicates a hazard that can lead to injury or damage to property if the caution is ignored
and the product is handled incorrectly.

1-2. WARNING

1) Do not supply a voltage higher than that specified to this product.
This may damage the product and may cause fire.

2) Do not use this product in locations where the humidity is extremely high,
where it may be splashed with water, or where flammable materials surround it.
Do not install or use the product in a location that does no satisfy the specified
environmental conditions.This may damage the product and may cause a fire.

3) If a foreign substance (such as water, metal, or liquid) gets inside the product,
immediately turn off the power. Continuing to use the product, it may cause fire or
electric shock.

4) If the product emits smoke, and abnormal smell, or makes an abnormal sound,
immediately turn off the power. Continuing to use the product, it may cause fire or
electric shock.

5) Do not disconnect or connect the connector while power to the product is on.
It takes some time for the voltage to drop to a sufficiently low level after the power has
been turned off.Confirm that the voltage has dropped to a safe level before
disconnecting or connecting the connector.

6) Do not pull out or insert the power cable from/to an outlet with wet hands.
It may cause electric shock.

7) Do not damage or modify the power cable. It may cause fire or electric shock.

8) If the power cable is damaged, or if the connector is loose, do not use the product:
otherwise, this can lead to fire or electric shock.

9) If the power connector or the connector of the power cable becomes dirty or dusty,
wipe it with a dry cloth. Otherwise, this can lead to fire.

10) MIS-4201 set uses a high voltage (Max.450V DC). Keep the cautions concerning
electric shock and do not touch the Device circuitry when handling the PDP Unit.
And because the capacitor of the Device circuitry may remain charged at the
moment of Power OFF, standing by for 1 minute is required in order to touch the
Device circuitry

.

11) In order to protect static electricity due to C-MOS circuitry of the Drive part, wear a
wrist band to protect static electricity when handling.

12) When cleaning the Panel, wipe it with a soft cloth moistened with water or neutral
detergent, be careful not to touch the connector part of the Panel. And don’t use
chemical materials like thinner or benzene.

13) If this product is used as a display board to display a static image, “image sticking”
occurs. This means that the luminance of areas of the display that remain lit for a
long time drops compared with luminance of areas that are lit for a shorter time,
causing uneven luminance across the display.
The degree to which this occurs is in proportion to the luminance at which the
display is used. To prevent this phenomenon, therefore, avoid static images as
much as possible and design your system so that it is used at a low luminance, by
reducing signal level difference between bright area and less bright area through
signal processing.

14) Because PDP Module(set) emits heat from the Glass Panel part and the Drive
circuitry, the environmental te mperature must not be over 40°C. the temperature of
the Glass Panel part is especially high owing to heat from internal Drive circuitry.
And because the PDP Module(set) is driven by high voltage, it must avoid
conductive materials.

15) When inserting components or circuit board in order to repair, be sure to fix a lead
line to the connector before soldering.

16) When inserting high-power resistor(metal-oxide film resistor or metal film resistor)
in order to repair, insert it as 10mm away as from a board.

17) During repairs, high voltage or high temperature components must be put away
from a lead line

18) This is a Cold Chassis but you had better use a cold transformer for safety during
repairs. When repairing electricity source part, you must use the cold transformer.

19) Do not place an object on the glass surface of the display. The glass may be broken
or be scratched.

20) This product may be damaged if it is subject to excessive stresses
(such as excessive voltage, current, or temperature).
The absolute maximum ratings specify the limits of these stresses.

21) The recommended operating conditions are conditions in which the normal
operation of this product is guaranteed. All the rated values of the electrical
specifications are guaranteed within these conditions.
Always use the product within the range of the recommended operating conditions.
Otherwise, the reliability of the product may be degraded

22) This product has a glass display surface. Design your system so that excessive
shock and load are not applied to the glass. Exercise care that the vent at the
corner of the glass panel is not damaged.
If the glass panel or vent is damaged, t he product is inoperable.

.

23) Do not cover or wrap the product with a cloth or other covering while power is
supplied to the product.

24) Before turning on the power to the product, check the wiring of the product and
confirm that the supply voltage is within the rated voltage range. If the wiring is
wrong or if a voltage outside the rated range is applied, the product may
malfunction or be damaged.

25) Do not store this product in a location where temperature and humidity are high.
This may cause the product to malfunction. Because this product uses a discharge
phenomenon, it may take time to light (Operation may be delayed) when the
product is used after it has been stored for a long time. In this case, it is
recommended to light all cells for about 2 hours (aging).

26) This product is made from various materials such as glass, metal, and plastic.
When discarding it, be sure to contact a professional waste disposal operator.

27) If faults occur due to arbitrary modification or disassembly, Orion PDP Co. ,Ltd..is
not responsible for function, quality or other items.

28) Use of the product with a combination of parameters, conditions, or logic not
specified in the specifications of this product is not guaranteed. If intending to use
the product in such a way, be sure to consult Orion PDP Co.,Ltd. in advance.

29) Within the warranty period, general faults that occur due to defects in components
such as ICs will be rectified by Orion PDP Co Ltd. However,
IMAGE STICKING due to misapplying the above (12) provision is not included in
the warranty. Repairs due to the other faults may be charged depending on
responsibility for the faults.

5. Board Description

5-1. I/P PCB

For input signal, S-video signal to separately enter luminance and color
signals, Y/C composite video signal, DVD signal, DTV signal and the

graphic signals of analog RGB and digital RGB can be used. In case of
graphic signals, both analog and digital versions use AD9887 ADC.
Each of 3CH even/ odd signals are converted into 8bit signals and
entered to scaler. Similarly, DTV signals are also entered to scaler
through the same route. Video signals are converted to the digital format
of BT601 through the video processor of VPC3230D. Among input
signals, CVBS (only NTSC) is entered to VPC3230D as Y/C is
separated through 3D-comb filter. VPC3230D converts the format of
input signals into 16-bit BT601, thus enters them to the deinterlacer of
MDIN-150. MDIN-150 converts interface signal into progressive to send
signal output to scaler. The output signal format is BT601, that is, Y:U:V
4:2:2 16bit. Scaler receives the input of MDIN-150 from control of
CPU[RDC R2021] and graphic signal from AD9887, thus administers
scaling to the resolution of multi-panel [853*480] and produces signal
output in LVDS format.

5-2. DIGITAL PCB

DIGITAL PCB receives the following signals and data from IP Board.

*LVDS FORMAT

- R, G, B data - DCLK

- Enable - H Sync.

- V Sync. - etc.

The data of R, G, B received from IP PCB is processed and adjusted to be
displayed in PDP through CON PCB and COF (Data drive circuit. )
DIGITAL PCB also has APL(Automatic Power Limit) circuit which controls

the power consumption and the heat in the PDP.
The data of H Sync, V Sync and DCLK is converted to X, Y & Z Timing pulse
data for PDP.
It is also working to reduce the Dynamic false contour and to maximize the
256 Gray level.
