SAFETY PRECAUTIONS
WARNING : TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO
RAIN OR MOISTURE.
●This Plasma Monitor should be set in the way indicated. If not, it may result in a fire hazard.
●Take appropriate space on the top, sides and rear of the Plasma Monitor cabinet for allowing air circulation and
cooling the Plasma Monitor. Minimum distance should be taken. If the Plasma Monitor is to be built into a
compartment or similarly enclosed, the minimum distances must
be maintained. Do not cover the ventilation slot on the Plasma
Monitor. Heat build-up can reduce the life of your Plasma
Monitor, and can also be dangerous.
●If the Plasma Monitor is not to be used for an extended time,
unplug the Plasma Monitor from the power outlet.
READ AND KEEP THIS OWNER'S MANUAL FOR LATER USE.
SIDE and TOP REAR
CAUTION IN INSTALLING
●Handle the Plasma Monitor carefully when installing it and do not drop.
●Locate set away from heat, excessive dust, and direct sunlight.

NOTE :
When Plasma Monitor is not used for a long period of time, unlighting dots may be observed. This is caused by
characteristic of the Plasma Monitor. If this occurs, turn the Plasma Monitor on and leave it on about 1 hour. These
dots will gradually disappear.
■Safety Instructions
Product safety should be considered when a component replacement is made in any area of the monitor.
Components indicated by mark in the parts list and the schematic diagram designate components in
which safety can be of special significance. It is, therefore, particularly recommended that the replacement of
there parts must be made by exactly the same parts.

■Setting the fixed data
(1) Receive the good quality signal.
(2) Enter the Service Mode
(3) Confirm fixed data to be same as data table. If it is different, change to
correct data.
(4) Return to the Normal Mode
This adjustment is controlled by the CPU (IC801) thorough the IIC Data Bus Line in the chassis, and those
adjustment data are memorized into the memory IC (IC808). Therefore, SUB CPU Board or the memory
IC (IC808) is replaced, data of those will be disappeared. Readjustment should be made. Initial data is
provided in the CPU ROM ,when memory IC (IC808) is replaced with new one, CPU ROM data is loaded
into the memory. (Data list will be shown in previous 2 pages.) Initial data is provided to operating the
monitor basically. For operating the monitor quality performance, further adjustment required following
chassis electrical adjustment.

Signal Flow
(1) CVBS, Y/C
CVBS (Composite Video) or Y/C signal from AV1, AV2 or AV3 terminal is input to AV SW IC (IC1001) and
selected signal.
CVBS signal selected by IC1001 is input to 3 Dimension Y/C Separation IC (IC7101) and input to IC1001 again.
(In case of NTSC Signal) On the other hand it is input to Digital Decoder IC (IC401) and output for Monitor Out
signal (CVBS only).
(2) RGB, Component
RGB or Component signal from AV4 terminal is output for “Through Out” terminal and input to RGB /
Component SW IC (IC1123) and selected to D-SUB RGB signal. Selected signal by IC1123 is input to IC1124.
(3) Decoder, I/P Conversion
CVBS or Y/C signal from IC1001 or Component signal (480i) from IC1124 is input to Digital Decoder IC
(IC401). Component signal from IC401 is input to I/P (interlace / Progressive) Conversion IC (IC501).
(4) A/D Conversion
RGB ( or Progressive Component) signal from IC1124 is input A/D Conversion IC (IC207) and converted.
(5) Panel Drive
Signal from IC501 or IC207 is input to RGB Matrix IC (IC601) and proceeded for picture control.
Signal from IC601 is input to Main Scaler IC (IC301) and LVDS Interface IC (IC751) and input to PDP Panel
Module.
